I decided to make a concrete dollar model to try to make the SaaS economic model more understandable (to me as well, because it’s hard to get my mind around it and actually grasp what they are doing). I’m guessing at the figures and will be glad to have others make suggestions, but my figures do seem to come out pretty realistic (in the ball park, anyway). Here goes:
Let’s say our SaaS company, ABC, has $100 million in annual revenue. It’s growing revenue at 60% and will thus grow revenue by $60 million this year. For simplicity sake let’s say it adds $15 million each quarter.
If ABC was selling refrigerators it would have to cost them a lot less than $15 million in S&M each quarter for them to be profitable, but ABC is selling a complicated set of programs that have to be integrated into the customer company’s business with no resulting problems, and this takes a lot longer and a lot more effort than selling refrigerators. Let’s say that ABC will be happy if the first year’s lease covers the cost of S&M… a “one-year payback,” as they will have the customer for many years (which is the key to their model).
Let’s say there is a one-year contract paid in advance. (If someone wants to do the model with a two-year contract that would be nice, or altering the payback period, or whatever)
Okay, we had decided that they sign a quarter of the new customers each quarter:
The first quarter new customers pay for 12 months but on average only 10½ months are recognized as revenue in 2018
The second quarter new customers pay for 12 months but on average only 7½ months are recognized as revenue in 2018
The third quarter new customers pay for 12 months but on average only 4½ months are recognized as revenue in 2018
The fourth quarter new customers pay for 12 months but on average only 1½ months are recognized as revenue in 2018
So 24 months of new customer payments get recognized, out of 48 months actually paid in 2018. (On average, it’s as if they all signed up in the exact middle of the year, all paid one year’s lease, and all only had six months of that lease recognized as revenue in 2018).
We said that ABC would be happy if the first year’s lease covers the cost of S&M (one-year payback). So ABC paid out the equivalent of 48 months of new contracts as S&M expense in 2018, but only 24 months got recognized. Are you with me so far?
What does that mean in dollars? Let’s go back to see:
ABC has $100 million in annual revenue. It’s growing revenue at 60% and will thus grow revenue by $60 million this year. But they have a dollar-based net retention rate of 120%, so they only are recognizing $40 million in new-client revenue. And we just figured out that they paid $80 million in sales and marketing expense in 2018 to get the new $40 million that was recognized. (This doesn’t worry them in the slightest because the rest of those first year contracts will be recognized during the next year with no new S&M expense. And they already have the money in the bank).
Let’s go on. That $20 million that they got in expanded sales from existing customers probably cost them something too, but these are established customers, so it doesn’t cost as much to sell them. Let’s say just it costs just a quarter as much. The $20 million recognized came in from added contracts sold spread out over the course of the entire year, so it means there were $40 million in actual added annual contracts, of which only $20 million was recognized as revenue in 2018, and since these were only a quarter as expensive as the new contracts, the $40 million cost just $10 million in sales and marketing expense.
Finally we have the $100 million existing contracts that were renewed during the year. For simplicity, lets say they only cost one-tenth as much as selling a new contract so they added another $10 million in sales and marketing expense.
Thus for 2018, we’ll have $100 million in sales and marketing total expense (80 + 10 + 10), and $160 million in recognized revenue. Thus S&M expense came to 62.5% of recognized revenue, which is pretty representative of a lot of our SaaS businesses. When you add in R&D and G&A expense, that’s probably enough to give them a small “loss” on the year.
But should we worry about that loss? They re-signed $100 million of existing customers at a total cost of $10 million. They upsold $40 million per year, at a cost of $10 million total, and they signed $80 million per year in new business for $80 million, but those new customers will renew next year probably for $96 million at a much lower S&M expense (120% dollar-based net retention).
I recognize that there are flaws in this simplified calculation of course, lots of them that I can see myself, but as a birds-eye overall view, and an attempt to make a complicated situation understandable, I hope it helps. If someone else can make a better example it would be wonderful! I’m worn out.
Best,
Saul
