1. The Churn Reality
TL;DR > Validating a SaaS is not just about proving someone will buy it once. You must prove they will use it repeatedly. You are validating retention.
SaaS (Software as a Service) is the holy grail of business models because of recurring revenue. But that means your validation must prove that the problem is recurring. If the problem only happens once a year, you do not have a SaaS.

The Monthly Churn Death Zone
If your SaaS churns 5% of its customers every month, you lose nearly half your customer base every year. You must validate retention early to survive.
2. The Concierge SaaS
Before you build the software, be the software. If you are building an automated bookkeeping SaaS, charge 5 companies $100/month for bookkeeping. Do the work manually in Excel on Friday nights.
If they cancel after month 2, ask why. Did the "software" (you) make a mistake? Or is the problem just not painful enough to pay for continuously?
