Revenue growth
A company’s long-term sales performance can indicate its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Over the last five years, RingCentral grew its sales at a 12.1% annual rate. Though this growth is acceptable on an absolute basis, we need to see more than just topline growth for the software sector, which can display significant earnings volatility. This means our bar for the sector is particularly high, reflecting the non-essential and hit-driven nature of the products and services offered. Additionally, five-year CAGR starts around Covid, when revenue was depressed then rebounded.
Long-term growth is the most important, but within software, a half-decade historical view may miss new innovations or demand cycles. RingCentral’s recent performance shows its demand has slowed as its annualized revenue growth of 5.5% over the last two years was below its five-year trend. We’re wary when companies in the sector see decelerations in revenue growth, as it could signal changing consumer tastes aided by low switching costs. 
This quarter, RingCentral reported year-on-year revenue growth of 5.9%, and its $676 million of revenue exceeded Wall Street’s estimates by 1.3%. Company management is currently guiding for a 5% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 4.1% over the next 12 months, similar to its two-year rate. This projection doesn’t excite us and implies its products and services will face some demand challenges.

Billings
Billings is a non-GAAP metric that is often called “cash revenue” because it shows how much money the company has collected from customers in a certain period. This is different from revenue, which must be recognized in pieces over the length of a contract.
RingCentral’s billings came in at $676.8 million in Q3, and over the last four quarters, its growth was underwhelming as it averaged 6.8% year-on-year increases. This performance mirrored its total sales and suggests that increasing competition is causing challenges in acquiring/retaining customers. 
Customer acquisition efficiency
The customer acquisition cost (CAC) payback period represents the months required to recover the cost of acquiring a new customer. Essentially, it’s the break-even point for sales and marketing investments. A shorter CAC payback period is ideal, as it implies better returns on investment and business scalability.
It’s relatively expensive for RingCentral to acquire new customers as its CAC payback period checked in at 1,808.7 months this quarter. The company’s slow recovery of its sales and marketing expenses indicates it operates in a highly competitive market and must invest to stand out, even if the return on that investment is low.
Key takeaways from RingCentral’s Q3 results
We enjoyed seeing RingCentral beat analysts’ adjusted operating income expectations this quarter. We were also happy its billings outperformed Wall Street’s estimates. Overall, this print had some key positives. The stock traded up 14.8% to $91.14 immediately following the results.
RingCentral put up rock-solid earnings, but one quarter doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. If you’re making that decision, you should consider the bigger picture of valuation, business qualities, as well as the latest earnings. We cover that in our actionable full research report which you can read here (it’s free).
