Eric B. Stang - President, CEO & Chairman
Thank you, Matt. Hi, everyone. Welcome to Ooma's Q4 Fiscal Year 2022 Earnings Call. Thank you for joining us today. I'm pleased to report we exceeded expectations for Q4 and our full fiscal 2022 year. And I'm excited to talk with you about our outlook and the many initiatives we have underway to drive growth in our upcoming fiscal year.
We capped off our fiscal 2022 with Q4 revenues of $50.5 million, representing 14% growth year-over-year. Total revenue for fiscal 2022 was $192.3 million, up $23.3 million from fiscal 2021 and also representing 14% growth year-over-year. We accomplished this growth while increasing our ARPU, generating EBITDA of $15.6 million and increasing our cash on hand to over $30 million.
FY '22 was a strong year for us and one we're proud of. Looking back at FY '22, we're also proud of the investments we made in our future. As I go through my remarks today, I will highlight a number of growth opportunities that we put in place during FY '22 and which hold tremendous potential for this year and beyond.
Looking first though at our progress in Q4, we continued to execute our core strategy of growing our SMB and enterprise subscription revenues through feature enhancements and sales and marketing expansion. For our SMB customers, we added features such as hot desking, which facilitates shared workspaces; Dynamic Caller ID, which allows individual control of Caller ID, and calendar integration with Google G Suite and Microsoft Office 365.
We also continued development of our upcoming Pro Plus tier, which will extend our range of features to serve even larger businesses and facilitate further ARPU growth for Ooma Office. I'm pleased to report we remain on track to launch Ooma Office Pro Plus in Q2 of this year.
For our Enterprise customers, we launched our integration with Jazzware to link Ooma's UCaaS features with Jazzware's cloud service and control of property management solutions. Our plan is for Ooma and Jazzware together to enable advanced features for the hospitality industry. We also continued our ongoing effort to modernize each of the ways our users interact with Ooma Enterprise.
In this regard, I'm pleased to report that we believe we will complete our update of Ooma Enterprise in the first half of this year with the release of new mobile apps and an updated admin portal. On the sales and marketing front, we made good progress, although we did face some headwinds driven by the intensity of Omicron and typical Q4 seasonality. One particularly exciting new customer for Ooma Office in Q4 is a large fast food franchise group with over 300 users. We also added more than 150 new locations representing nearly 500 users with franchises of a large services firm, bringing us in total now to over 5,000 franchise users with this firm.
In hospitality, we landed 6 new properties in Q4 and are seeing our backlog of opportunities build since the recent launch of our Jazzware integration. We also signed with over 80 new agents and VARs in Q4 as part of our continued effort to expand sales through channel partners and resellers. All in, we made good progress expanding our business in Q4.
We also accomplished a lot in Q4 to enable our largest customer to roll out at scale to more users. While we know this has been a long time coming, we fully expect that rollout will begin in Q1 and accelerate through the balance of the year. In addition, through our efforts over the last couple of quarters, we have expanded the longer-term scope of opportunity for us with this customer. Our immediate goal, as we stated previously, is to add 25,000-plus users taking us to 50,000 users approximately in total. And once that is achieved, we anticipate further expansion will follow.
Last quarter, we made the exciting announcement that we are introducing Ooma AirDial. As you'll recall, AirDial provides analog to digital conversion, remote management, battery backup and wireless LTE over a controlled network to replace copper lines serving critical building applications. The market reception to AirDial has been strong, and we have already signed multiple resellers. Currently, we have beta units in use at customers and production underway of AirDial units that will be available for sale starting late Q1.
We anticipate our biggest challenge through this year will not be demand, but rather our ability to build and supply units. At this time, we are conservatively forecasting AirDial in our business outlook until we have more certainty on market development, our build quantities and timing. Nonetheless, we see significant upside potential for AirDial in FY '23 and are actively working internally to execute on this opportunity.
Last quarter, we also made the exciting announcement that T-Mobile will offer Ooma Telo to T-Mobile's 5G Home Internet customers. Ooma and T-Mobile are working together to pursue this opportunity, and Telo is the only solution being offered. We're excited by T-Mobile's significant growth plans for home Internet and by the continued market demand we see from customers who want to combine Internet with home phone. As of now, Telo is included as an add-on option on T-Mobile's website and joint work is underway to implement other marketing initiatives. We are experiencing sales every day with T-Mobile, but still too early to forecast the full potential of this partnership.
As we look forward to FY '23, we believe we have built a solid foundation for growth. We see ourselves today as a leader in each of our target segments, serving SMB customers, select enterprise applications and residential customers. We have built a robust and very flexible end-to-end platform that is operating at large scale, serving approximately 2.5 million users today. Online marketing and direct sales are strategic competencies of ours, and we are investing to build our channel reseller sales. Our scope now extends beyond North America to Europe and soon will extend beyond that to other regions of the world. We are increasingly charting our own direction as we broaden our solutions to include integrated services such as Ooma Connect, Ooma Wi-Fi and Ooma AirDial.
Overall, we are not only driving growth but also generating positive cash flow from operations. Our accomplishments to date create a strong foundation for future growth. Strategically, our vision remains to provide leading communications and related services that deliver advanced features, superior ease of use and uncommon value to businesses worldwide.
As we seek to implement this vision, we are focused in FY '23 on 5 priorities for growth. First, execute to grow sales to business customers. In particular, we intend to launch Ooma Office Pro, which is a higher service tier, to expand our sales and marketing activities and to continue to build our brand recognition. Number two, develop new verticals and stronger channel sales. As part of achieving this, we intend to grow the number of agents and bars we work with and to strengthen our support for channel resellers.
Number three, expand in Europe. We'll achieve this in FY '23 by rolling out service to a large number of new users as part of our expansion plans with our largest customer. Number four, capitalize on AirDial to replace copper lines that are sunsetting. Our intention is to create both the most extensive solution and the best value solution and be the leader serving this opportunity. And finally, number five, leverage the transition to 4G and 5G Internet to drive added growth. With Telo offered by T-Mobile and with Ooma Connect, we have the first steps in place to achieve this. As you can see, while we have a lot to accomplish this year, we also have more opportunity in front of us than ever before.
I will now turn the call over to Shig, our CFO, to discuss our results and outlook in more detail and then return with some closing remarks.
Shigeyuki Hamamatsu - VP, CFO & Treasurer
Thank you, Eric, and good afternoon, everyone. I will begin with a review of our fourth quarter and full year fiscal 2022 financial results and then provide our outlook for the first quarter and full fiscal year 2023.
We delivered another quarter with strong financial results, achieving $50.5 million in total revenue, exceeding our guidance range of $49.7 million to $50.2 million. On a year-over-year basis, total revenue grew 14% in the fourth quarter driven by the strength of Ooma business subscription and services revenue, which accounted for 49% of total subscription and services revenue as we continue to make progress towards achieving more than 50% of our subscription and services revenue coming from business customers in the near future.
On a full year basis, total revenue was $192.3 million compared to $168.9 million in the prior year, representing 14% growth year-over-year, including 23% growth in Ooma business subscription and services revenue. Non-GAAP net income for the fourth quarter was $3.2 million, which exceeded our guidance range of $2.3 million to $2.8 million. And net income for full year fiscal '22 was $12.6 million compared to $11.5 million in the prior year driven by the growth in subscription and services revenue and expansion of related gross margin.
Now some details on our revenues for Q4 and fiscal 2022. Ooma business subscription and services revenue grew 19% year-over-year in Q4 and 23% for fiscal year 2022 driven by user growth as well as ARPU growth. Residential subscription and services revenue grew 3% for both fourth quarter and full fiscal year 2022. For the fourth quarter, total subscription and services revenue was $45.8 million or 91% of total revenue compared to 93% in the prior year quarter.
During the fourth quarter, as expected, we saw product and other revenue increase to $4.7 million as compared to $3.1 million for the same period last year driven by the sale of additional units of our fixed wireless products to the same strategic customer, which we discussed in our third quarter earnings call.
Now some details on our key customer metrics. We ended fiscal 2022 with 1,100,000 core users, up from 1,074,000 core users at the end of the prior fiscal year driven by the growth in business users. I am excited to report that we now have 308,000 business users, which represented 28% of our total core users, up from 25% at the end of the prior fiscal year.
Our blended average monthly subscription and services revenue per core user or ARPU increased 8% to $13.41, up from $12.46 in the prior year quarter driven by an increase in mix of business users, including higher ARPU Office Pro users. During the fourth quarter, 44% of our new Office users opted for Office Pro service and for full fiscal year 2022, 45% of new Office users opted for Pro service, which was up from 40% in the prior fiscal year. Overall, 20% of our Office users have now subscribed to our Pro tier.
Our annual exit recurring revenue in Q4 grew to $176.9 million and was up 10% year-over-year. Our net dollar subscription retention rate for the quarter was 96%, which remained stable compared to the prior year quarter. For the entirety of fiscal 2022, our quarterly net dollar retention rate averaged 98%, which was an improvement from 96% in fiscal 2021.
Now some details on our gross margin. Our subscription and service gross margin for the fourth quarter was 73%, which was an improvement from 72% in the prior year. The improvement in subscription and service gross margin was driven by our increase in scale and the greater mix of higher ARPU business customers.
Product and other gross margin for the fourth quarter was negative 49% compared to negative 58% for the same period last year. This improvement over the prior year quarter was mostly due to the sale of fixed wireless products to the strategic customer I mentioned earlier. On an overall basis, total gross margin for Q4 was 62% as compared to 63% for the same quarter prior year as we had a higher mix of product revenue during the quarter.
And now some details on operating expenses. Total operating expenses for the fourth quarter were $27.9 million, up $3 million or 12% from the same period last year. Sales and marketing expenses for the fourth quarter were $14.5 million or 29% of total revenue, up 13% year-over-year driven by higher marketing and channel development activities for Ooma Business. Research and development expenses were $8.9 million or 18% of total revenue, up 9% on a year-over-year basis from $8.2 million driven by investments in new features for both Ooma Office and Ooma Enterprise as well as new products such as Ooma AirDial.
G&A expenses were $4.5 million or 9% of total revenue for the fourth quarter compared to $3.9 million for the prior year quarter. On a non-GAAP net income of $3.2 million resulted in a diluted earnings per share of $0.13 for the fourth quarter as compared to $0.12 of diluted earnings per share in the prior year quarter. Adjusted EBITDA for the quarter was $4 million or 8% of total revenue as compared to $3.6 million for the prior year quarter.
Adjusted EBITDA for full fiscal year '22 was $15.6 million as compared to $14 million in the prior fiscal year. The increases in non-GAAP net income and adjusted EBITDA were driven by economies of scale, especially for the growth -- especially the growth in subscriptions and services revenue and related gross margin.
We ended the quarter with total cash and investments of $31.3 million compared to $28.3 million at the end of Q4 in the prior year. Cash generated from operations for the fourth quarter was $1.8 million compared to $2.2 million in the same period last year. For full fiscal year 2022, cash generated from operations was a record $6.7 million as compared to $4.4 million in the prior year.
On the headcount front, we ended the quarter with 979 employees and contractors. Now I will provide guidance for the first quarter and full fiscal year 2023. Again, our guidance is on a non-GAAP basis and has been adjusted for expenses such as stock-based compensation and amortization of intangibles. For the first quarter of fiscal 2023, we expect total revenue to be in the range of $49.5 million to $50.2 million.
The first quarter revenue guidance range assumes product and other revenue will normalize to the level we saw in the first half of fiscal 2022, as we do not anticipate additional shipment of fixed wireless products to the same strategic customer discussed earlier. The guidance range also reflects a normal seasonal decline of Talkatone revenue in the first quarter as Talkatone revenue typically peaks in the fourth quarter driven by its ad-based revenue over the holiday season. We expect the first quarter net income to be in the range of $2.2 million to $2.8 million. Non-GAAP diluted EPS is expected to be between $0.09 to $0.11. We have assumed 25.1 million weighted average diluted shares outstanding for the first quarter. For full fiscal 2023, we expect total revenue to be in the range of $209.5 million to $212.5 million.
Let me give you additional context for our fiscal 2023 revenue guidance. It is important to remember that fiscal 2022 revenue included approximately $3 million of product revenue to a strategic customer that we currently do not anticipate will recur in fiscal 2023. Excluding the impact of this product revenue in fiscal 2022, the midpoint of our fiscal 2023 revenue guidance represents approximately 11.5% revenue growth year-over-year, which assumes subscription and services revenue growth rate of 20% of Ooma Business and between 1% to 2% for Residential.
The revenue guidance for full fiscal year 2023 also reflects our current expectation that contribution from AirDial will be more meaningful in the second half of the fiscal year. We expect non-GAAP net income for fiscal 2023 to be in the range of $8.5 million to $10.5 million after incorporating increasing cost of labor, costs to expand our channel strategy, launch new products such as AirDial and to enable significant expansion of services in international locations. We expect non-GAAP diluted EPS for fiscal 2023 to be in the range of $0.33 to $0.41. We have assumed approximately 25.7 million weighted average diluted shares outstanding for fiscal 2023.
In summary, we are very pleased with a solid performance in fiscal 2022, which demonstrates strength in our execution while we make progress towards our long-term objectives. I'll now pass it back to Eric for some closing remarks. Eric?
Eric B. Stang - President, CEO & Chairman
Thanks, Shig. I mentioned at the outset of my remarks that in FY '22, we made significant investments in our future. Those investments in international expansion, in higher-level service tiers, in the development of new verticals and channels, in creating the most complete solution for replacing copper lines, in partnering Telo with T-Mobile and more, now they all position us better than ever for FY '23. While our visibility and what we will achieve in FY '23 will improve through the year, we clearly have the potential to drive significant growth. As always, the Ooma team is 100% focused on building Ooma's long-term success.
Thank you. We will now take your questions.

(Operator Instructions) Your first question today comes from the line of Matt Stotler with William Blair.
Matthew Alan Stotler - Analyst
I guess, first off, it's helpful color you gave on the guidance and kind of the puts and takes, both on the large customer and some of the seasonality in Q1. It's been kind of a tough environment towards the end of the year, early this year for a lot of people. And we saw, looking at some of the KPIs and net adds, were a little bit down sequentially, retention took a little bit of a step down. There's a little bit of a deceleration in business revenue growth. So can you just talk about maybe some of the factors that you saw that impacted those KPIs, whether it's seasonality or what you saw with Omicron and some of those face-to-face channels potentially? And then thoughts on how those -- how to think about those going forward?
Eric B. Stang - President, CEO & Chairman
Sure. Matt, you hit some of the issues right there in your question. If you look at Q4, it was December that was the tough month of the quarter for us. We -- with Omicron and seasonality, we had a tougher December than we'd expect. But we bounced back well in January. I would add a secondary comment. This was less significant for us, but we did launch a new line of IP phones in the quarter, and we had some teething pains with those phones as we first brought users up on them. And that affect us a little bit as well.
But what I can say is that January was strong, February is running at the kind of run rates that would lead to us back at our previous middle of last year churn levels. And also back at our previous of last year, adding net business users in, how do I say it, 5 figures, over 10,000 for the quarter. So I'm feeling pretty good about the business for where we are today. But you're right, Q4, particularly in the December period was a little challenging.
Matthew Alan Stotler - Analyst
Got it. Got it. That's helpful. And then maybe one on the vertical-specific opportunities. You talked a little bit about the specific opportunities in hotels and hospitality, and you made some announcements around that after the Jazzware partnership. How do you think about the potential for additional -- obviously, this one's still early, right? So maybe some thoughts on how that plays out? And then the potential for additional vertical-specific opportunities going forward and maybe what you're focused on there?
Eric B. Stang - President, CEO & Chairman
Yes. Well, you've captured our strategy at the enterprise level pretty distinctly with the question. Rather than trying to be everything to everybody, we're finding applications and verticals where our unique capabilities can really differentiate. In hospitality, particularly in conjunction with Jazzware, we have a great kind of integrated solution that can bring UCaaS features together with more basic features for powering individual rooms, analog and digital combined, connected up to PMS systems. So it's become a bit of a focus for us. It's a way to develop our business and also, frankly, convince new channel partners and resellers to work with us because we've got something special to bring to them.
In that vein, AirDial also is helping us open up new channel partners -- new channel reseller relationships because, again, we have something that's fairly unique in the industry that causes these resellers to want to work with us. Through this year, we are intending to develop additional verticals. We have some that I could talk with you about here, but they take time to really come together and they -- our -- they're strongest when we can bring some real extra dimensionality around the feature set as well. But no, that's part of our strategy for building Enterprise, and we'll at least target a couple more this year.

Your next question comes from the line of Josh Nichols with B. Riley.
Michael Joshua Nichols - Senior Analyst of Discovery Group
I'd like to touch on T-Mobile. It seems like an interesting longer-term opportunity. I realize it's early stage, but any commentary you can make like what type of traction you're seeing? And I'm curious how conservative you're being in your guidance for T-Mobile for this year on the revenue side, given that you did mention it's relatively early stage. Could you elaborate on that a little bit, please?
Eric B. Stang - President, CEO & Chairman
Yes. Happy to. It starts with T-Mobile's own comments around their intentions with home Internet. They are very committed to the space. They talked about building out their user base to millions of users as we look forward to the next few years. I won't try to requote what they've said, but I'm sure you can look back at that. That's exciting.
And alongside that effort, they feel, and I think the market has spoken, that some customers want to have what we call a double-play solution, have phone service and Internet together. So there's a natural fit between the 2 of us. And in addition, some customers may be switching away from cable-based solutions where they may already have both services and they want to continue to get both in order to switch. So it's a great partnership to work together on this. We do have a cadence of planning and marketing meetings with them as we develop the next steps that will happen to try to capture this opportunity.
So far, the only thing that's happened is the -- there's been a section put up on their website. When you buy home Internet, you can also click on that section to get phone service. We're seeing sales every day from that. But I would say what -- compared to what this could be, it's not big numbers today. But as I said, it's early stage. I think that you asked about how we forecasted it in our outlook. We forecasted it fairly low because we just want to wait to see how it unfolds.
We -- if we take the forecast that they gave us for how many units we should be planning for this year, it is a much, much bigger number than what we have in our forecast today. So let me just leave it at that. It's -- we thought we'd have a little bit more visibility than I can give you right now by this time, but December and January weren't the easiest times to kind of pursue this, and it's -- but it's developing well now.
Michael Joshua Nichols - Senior Analyst of Discovery Group
That provides some really good clarity. And then just to touch on that one more. Historically, 30-ish percent of the company's revenue has been allocated to sales and marketing. One of the really interesting things, at least from my perspective, with T-Mobile is the idea that you wouldn't have a lot of those expenses. You may have some. Is that fair to assume? Or is there going to be some joint marketing that you may do to partner with T-Mobile. How should we think about the flow-through?
Eric B. Stang - President, CEO & Chairman
No. What we're doing with T-Mobile, we're enabling their marketing and sales efforts. We have put together a special offer for their customers, but aside from that, we're really an enabler to them doing the things they want to do. And -- so far, we're just on their Internet website, but the joint plans discussed between both of us is to do more than that.
Michael Joshua Nichols - Senior Analyst of Discovery Group
Got it. And then last question for me, then I'll jump back in the queue. Just to elaborate a little bit. Looking at the guidance for this year, I think everything kind of makes sense on the revenue side, given what you said and some of the conservatism that's built in there, but I know the EPS guidance is going to be down year-over-year. Where are those additional investment dollars going to be allocated to? Is it going to be more front half, back half weighted? And how should we think about the operating side of the guidance?
Shigeyuki Hamamatsu - VP, CFO & Treasurer
Yes, Josh, thanks for the question. And with respect to the areas of investments, the biggest piece is going to be in the sales and marketing. And as we said before, we want to continue to invest into channel developments to drive the user growth on the business side. And I think in the whole of '22, we spent about 29%. That's -- as Eric and I said before, that's a little bit lower than we probably like to be to drive growth and -- so between the channel development and also hiring front, which we were behind in FY '22.
And also, just in general, as we come out of pandemic here and things normalize, we see that activities and trade shows and travel probably start to pick up towards the second half of the year. So those investments in sales and marketing. And I think we'll probably see that sales and marketing as a percent of revenue to be more like in the range of 31.5% to 32%. By the way, that level, it's still a low end of midterm model that we talked about in the past, but you want to invest.
And then other areas just across OpEx, as I said in my remarks, that there's a general increase in cost of labor, which is not unique to us, but -- and international expansion that with the largest customer we talked about. That piece, I mean, one can say that some of that spend I'm projecting in FY '23 is something that we originally intended to spend in '22. But because of the timing of the ramp with the largest customer, that's kind of moving into next year. So hopefully that gives you a little color there.

Your next question comes from the line of [Sharon Karuba] with Northland Capital Markets.
Unidentified Analyst
This is [Sharon] on behalf of Mike Latimore. Can you please talk about the pipeline for AirDial. And what are the marketing strategies you're currently using for it?
Eric B. Stang - President, CEO & Chairman
Sure. So the pipeline that we add up even now is more than we think we can produce this year. It's pretty encouraging. We don't know that we need to do that much marketing. We see 3 or 4 ways in which the product will go to market. One is through channel resellers who, as I spoke earlier, can bring AirDial in to meet the needs of their enterprise as they go to.
We are seeing some, call them, distributors or aggregators who want to be able to offer the solution. And we are also finding some CLECs that have a real need to be able to replace copper lines with this type of solution. So those activities, I mentioned we've already signed multiple -- we'd already signed up multiple parties to work with us on going to market for AirDial. I think there's a lot of interest in it. I think everyone is waiting for us to get going with it and get products flowing in quantity.
Unidentified Analyst
Okay. And in regards with your largest customer, do you think that they will be moving materially forward this year internationally?
Eric B. Stang - President, CEO & Chairman
Yes.

Your next question comes from the line of Matthew Harrigan with Benchmark.
Matthew Joseph Harrigan - Senior Equity Analyst
Actually reverting back to the target model that you alluded to. It feels like you've got a number of growth initiatives, and I know the priority, I mean, if you can get sales growth, you're going to opt for that at reasonable ROI versus just trying to top out the margins immediately.
But do you see the timing on the transition from the midterm to long-term margins getting pushed out a little bit by the level of activity that you have going on? Is there any flex at all in the long-term model? I know that some of this was probably devised by Shig's predecessor, but I'd just love to know if there's any sense of variation in timing of this, of the new initiatives or even some of the long-term objectives have maybe even been tweaked a little bit color wise.
Shigeyuki Hamamatsu - VP, CFO & Treasurer
Yes. So Matt, thanks for the question there. I think when I look at gross margin model, we talked about midterm or long-term model in the past. And I'm looking at this now. Midterm, we aim to be in the 62% to 65%, total margin I'm talking about. In subscription, 70% to 75%. We do feel good about the subscription margin. I think we're in the right middle of it, 73%. And as we scale further with user ads on the business side, and when AirDial ramps, that's a business user, so we think we have a path to continue to improve incrementally from where we are. So I -- we feel good about the subscription.
That's number one data point. I think the total gross margin, I know we reported 62% total this past quarter, but that's more a function of having a heavier product mix to that strategic customer last 2 quarters. So do keep in mind that product mix at the beginning of this past year did not expect to happen in the last half of this past year, that threw us off a little bit. But so going into next year, as I said, Q1, we expect the product -- the revenue mix, excuse me, between subscription revenue to go back to what it was in first half of last fiscal year, which means that more like a 93% subscription, 7% product. I see that in the first half.
And so that should improve our overall gross margin because it's going to be tilted more towards the subscription margin. That's one data point. And I think if we go into second half of next year, I'm seeing that the -- right now, the product mix I just describe -- revenue mix, excuse me, is probably shift towards 92% subscription, 8% product, only because we're anticipating a more meaningful ramp on AirDial, which has a product component to pick up, and so that changed the mix of the revenue a little bit. But overall, to answer your question, we still feel good about our midterm and long-term model, and I think we're progressing pretty well towards those.

And then on AirDial, you have the happy circumstance of functionally having the only alternative in the market from the vantage point of the CLECs, as you just said. And I'm curious, how long do you think you're going to have that circumstance where you're the real innovator and de facto the only alternative. Is that something that's kind of in your business plan? Or would you anticipate getting more competition or some competition at some point?
Eric B. Stang - President, CEO & Chairman
The market is big enough that there's already competition today, and there won't be more in the future. But when we look at that competition, it isn't approaching the solution the way we have. We are a unique company in that we can design hardware to work in conjunction with our cloud and provide an integrated service. And through our partnership with T-Mobile on this as well, that includes the wireless Internet that is part of the controlled network that these devices require.
So I think that we've -- there are competitors out there, but they tend to be small and they tend to be just product makers. And we have put together a very complete solution. So I feel like we're in a very good spot, and that will -- we'll be able to maintain that for a while. These things -- we've worked on this solution for about a year to get to where we are today. And now we're scaling up production, and scaling up production in this product environment is difficult because we don't have an existing supply chain for the product, we've got to create it, and trying to get components these days can be difficult. So I think what we've been doing over the last year puts us ahead of anyone else and maybe looking at this today as well.

It doesn't look like it's going to be getting easier immediately.

Your next question comes from the line of Andrew King with Colliers Securities.
Andrew King;Colliers International;Equity Research Associate
Eric, just really good to see this partnership with Jazzware going forward. Just want to get an idea how -- what hurdles do you have to go as you look to get the sales force ramp to efficiently sell a more specialized solution to the hospitality services area? And then off of that also, how many of these 80 VARs that you added in this quarter were hospitality focused?
Eric B. Stang - President, CEO & Chairman
So generally, when we work with agents and VARs, they're not focused on just an industry. But what they do find -- or what we do find is that when they get success in a vertical, they will follow it up with focus on it because it's something they know they can build. Of the 80-plus VARs and resellers we added, about half would be the type that I would say would be more focused on selling Ooma Office, and about half were of the type that I would say would be more focused on a larger company enterprise type sale.
And all of those resellers that we added from an Enterprise perspective, I can't say all, but I think a significant majority, would be easily capable of selling into the hospitality space. There are some resellers out there that are focused on that space and one in particular, we have just recently started to work with, and we're excited about that. So we're looking at it that way as well.
But no, these are -- it's traditional -- it's the way our space is traditionally developed, which is you've got, in this case, hotels, motels, et cetera, where they've got old, antiquated solutions that are expensive to run and they need to modernize and they're kind of stuck and you can come in with a solution that really takes some to a modern result. And that's the way you sell it. And the more success we have in the vertical though, the more we get known for it, and that helps us, too, as we grow. But I hope I've answered your question there with the different comments I just made.
Andrew King;Colliers International;Equity Research Associate
Yes. That's great. And then also just looking at the hospitality vertical, can you give us any color as to if there's any material differences in the sales process in the hospitality vertical versus the other verticals. And if there's any sort of seasonality we should expect in that business?
Eric B. Stang - President, CEO & Chairman
Well, like any vertical, it helps if you can talk their needs and walk in with solutions to the problems you know they're going to have. In this case, one of the key issues is -- or problems is how to integrate analog and digital capabilities together in one solution. A lot of these -- a lot of hospitality industry doesn't want to change the phones and rooms, but they do obviously need modern capabilities at the front desk and otherwise. So I think through focus, you can establish that. Also keep in mind, what's really underlying what we're doing in this vertical and underlie what we do in other verticals is our enterprise solution is very flexible. It's API-based. It's a very modern design, and we can use it both to customize for very large customers but also to do something like what we're talking about here with you about the hospitality space where we can put together something that's kind of unique to their needs.
And so with that, I think we're well placed to serve the vertical. In terms of seasonality, I don't see any particular seasonality in this regard. I think that it's just something we're going to have to build over time. And what will pace our growth a little bit is how fast we can bring on the agents and the resellers and get them comfortable with the solution and taking it to market.

Your next question comes from the line of Brian Kinstlinger with Alliance Global Partners.
Brian David Kinstlinger - Head of TMT Research, MD & Senior Technology Analyst
Great. In terms of T-Mobile and the Ooma Telo Air program, like you said, I looked on T-Mobile's website, on the ISP website. And to be honest, it's exceptionally hard to find. You got to scroll down. You almost have to be looking for it. So can you talk about when and the other ways, first, that T-Mobile is planning to make home Internet users aware of the program? How much inventory do you have to deliver this? And what are the lead times for suppliers?
Eric B. Stang - President, CEO & Chairman
Yes. So on the first question, I really shouldn't comment because it's -- I don't really want to talk about a partner and what they're going to do. I can tell you that they have plans to do significantly more than what you'll see on their website today. But I really can't get into what they're planning until they do it.
Yes, we have -- on the product availability side, we -- since last fall, we've been planning for the kinds of quantities that they've told us they'd like to get from us for this year. And I think in terms of the components needed that are unavailable if you don't plan ahead, we've put those plans in place.
Some components that we need to scale up to big quantities would probably cost us more in short term to get them, but we would work through that. So I feel we're placed well enough today that if -- as they do more things and more customers come to us through that relationship, we'll be able to satisfy it.
Brian David Kinstlinger - Head of TMT Research, MD & Senior Technology Analyst
Great. And then in terms of once that program ramps, is there going to be a hardware piece that pressures the margin while, and there's also the recurring piece? And then same question kind of on AirDial. When that starts to ramp, what's the impact it's going to have on the overall gross margin?
Shigeyuki Hamamatsu - VP, CFO & Treasurer
Sure. Yes, Brian. Thanks for the question. On the first piece on Telo, yes, so there's a product piece and subscription piece. And by the way, just a remainder. On the subscription piece, they are all premium users on the Telo side.
But the way I would say it is that we're not expecting right now that when it ramps that Telo cost of sales on the product side would have a materially different impact on the profile -- the gross margin profile on the product side. Right now, so if you look at -- like I said in the earlier remarks, Q2 last year, as we go into this Q1 and forward in FY '23, when I look at the normalized level of product revenue and gross margin profile for product revenue, it's about minus 50% to minus 55%.
So I think that's a good range even with the ramp of Telo through T-Mo. So that's one reference point for you. AirDial, it does have both the subscription component and also product component. The -- I do think that the -- on the product side revenue, we do think that has a positive impact on the product margin when we do ramp. So I'll just leave it at that without quantifying too much there since it's early. And also, it should have a positive impact on the subscription margin as well, and that's a business subscription by the way. So hopefully, that gives you some color there.

Your next question comes from the line of Joe Goodwin with JMP Securities.
Joseph P. Goodwin - VP & Equity Research Analyst
So Eric, on the 5 priorities for growth for FY '23, could you stack rank those in order of importance for you this year?
Eric B. Stang - President, CEO & Chairman
Sure. Joe, so I started off with number one is just executing the gross sales to business customers. I think that, that is #1 for us, to continue to bring out Pro Plus and expand our sales and marketing activities. We did not grow our sales and marketing team this last year like we wished. Hiring and other things were challenges, but we believe we will achieve it this coming year. After that, it's hard to rank the next 4. We are very focused on developing new verticals and stronger channel sales, but that is a longer-term multiyear strategy of ours which will -- some things will happen this year, some things will happen thereafter.
I feel pretty comfortable, as I've stated in the -- in my remarks, very comfortable actually, that we are going to expand our users significantly with our largest customer, and we're ready to go. And they are moving forward now, starting this quarter. So expanding in Europe will happen, I believe. We are not intending to expand beyond serving users at this large customer. We want to get that to happen and have that under our belt before we try to look at doing more with Ooma in Europe, particularly Ooma Office in Europe before -- so our focus this year is really expanding with our largest customer.
AirDial and the transition to 4G -- transition to 5G and what we're doing with T-Mobile, those have tremendous upside. I think in the first case, it'll depend on how many units we can build; and in the second, it will depend on what sales and marketing activities T-Mobile chooses to do and how they do them but -- and the market response. But I think each is material. So I don't know if I've answered your question very well, but after #1, we think all of the next 4 are important.
And we are -- we invested in all 4 of these last year. So as I look at this year, while it's a lot to say we're going to go do, I actually think most of the work on these next 4 is done, and so -- at least Europe, AirDial and Telo with T-Mobile. So I feel like we can accomplish all of them as well this year.
Joseph P. Goodwin - VP & Equity Research Analyst
Got it. Okay. And then just another question for me. Can you talk about the current strategy that you're employing to upsell your existing Ooma Office customers to Ooma Office Pro. Are you reaching now? Are you providing any sort of like offers or anything like that? Or just kind of how do you actually approach the upselling to your existing base?
Eric B. Stang - President, CEO & Chairman
So the upselling to our existing base is relatively simple. As we bring out a new feature in Ooma Office Pro, we just let our base know. And it's a way to reach out to them and show them what we can do. And if they're interested, they'll take it from there. And so we do have an installed base marketing program in the company, and that's essentially how we do it. We're not getting too aggressive with that. We don't give free trials. We don't offer special promotions or anything like that. But we do make a point to tell people about the exciting features as they come along. So when Pro Plus launches this year, that will give us a whole new basis to go out to our customer base with and tell them about now what's also available there.

Eric B. Stang - President, CEO & Chairman
Everyone, thank you for joining us today. I'll close with one final comment. It's just of a fun thing. I don't want to make too much out of this. But -- in January, we were named, Ooma was named one of the best tech brands for 2022. We were in the top 10 list, along with names like Tesla and Apple and Sony. It was a lot of fun. This was something that PCMagazine put out, I think, based on some kind of reader survey, though don't quote me on that.
But it's just fun to see that kind of recognition for Ooma. We're very focused on the customer experience and our users having a good experience and telling their friends is helping to drive our growth. And so it was rewarding to us as a team to see that. Thank you, everyone. Appreciate your time today, and look forward to next time we can talk. Bye-bye.
