Customer concentration risk in SaaS acquisitions
How to evaluate customer concentration before buying a SaaS business.
Quick Answer
Customer concentration risk in SaaS acquisitions
Customer concentration risk appears when a small number of customers represent too much revenue. In small SaaS acquisitions, one churned account can change the payback period, valuation, and buyer risk profile immediately.
What to check
Ask for revenue by customer and plan, then model the deal if the largest customer leaves.
- 01Top 1, 3, 5, and 10 customers by revenue.
- 02Contract terms and renewal dates.
- 03Usage depth for the largest accounts.
- 04Whether customers know the seller personally.
