What’s the biggest source of hidden revenue loss in your SaaS?

SaaS companies spend a lot of time optimizing acquisition but I’m curious about what happens after the customer converts.

In your experience, where does the most revenue quietly disappear?

• Customer churn
• Failed payments
• Downgrades
• Disputes & chargebacks
• Low product engagement
• Something else?

We’re building KeepRev around this problem, and I’d love to hear from other SaaS founders and operators.
