L/S SaaS Economics and Modeling Question

For a SaaS business, while the goal may be to drive higher ARR and a higher ARR per customer when focusing on growth, how does one think about a business when it seems like its new customer ARR and average ARR per new customer is inflecting and growing faster than previous quarters, but that is accompanied by lower expansion ARR and net retention rate? With this, ultimately, while the business is driving higher ARR with new customer expansion (and more ARR per new customers), likely because S&M efforts are very focused on these newer customers, net retention rate is going down with increased churn, and expansion ARR might start slowing in growth and start decreasing q/q. How does one think about this?

Ah, the classic SaaS conundrum! You're seeing new customer ARR and average ARR per new customer growing faster than previous quarters, but at the same time, you're noticing a decrease in net retention rate and potentially a slowdown in expansion ARR. This is a tricky situation, but let's break it down.

Firstly, it's important to remember that SaaS businesses are all about recurring revenue. So, while it's great that new customer ARR is growing, the decrease in net retention rate is a red flag. This could indicate that while you're acquiring new customers, you're losing existing ones at a faster rate. This is not a sustainable model for growth in the long run.

The decrease in expansion ARR is also concerning. Expansion ARR, or the additional recurring revenue from existing customers, is a key indicator of a SaaS company's health. If this is slowing down, it could mean that your existing customers are not finding enough value to upgrade their plans or purchase additional services.

So, how should you think about this? Well, it seems like the company is doing a great job at attracting new customers, but perhaps not enough to retain and expand existing ones. This could be due to a number of reasons - perhaps the product or service doesn't meet the needs of the customers as they grow, or maybe the customer service is lacking.

In this case, it might be worth shifting some focus from sales and marketing (S&M) efforts towards customer success and product development. Remember, it's often cheaper to retain an existing customer than to acquire a new one. Plus, happy customers are more likely to become advocates for your product, bringing in new customers through word-of-mouth.

In terms of modeling, you'd want to take these factors into account. Look at the trends in net retention rate and expansion ARR, and try to understand what's driving these changes. This will help you make more accurate projections and identify areas where the company can improve.

Remember, every cloud has a silver lining, or in this case, every SaaS business has an opportunity for growth. It's all about finding the right balance between new customer acquisition and existing customer retention and expansion.
