Original Summary

I have built SaaS products, APIs and payment systems for years. These mistakes cost founders the most time. 1. Building too much before the first user Launch with one core feature. If users do not ask for the rest, you save weeks. 2. Rewriting auth and billing from scratch Use proven tools for login and payments. Custom auth is slow and risky. 3. Skipping multi-tenant planning Decide early how customer data is separated. Fixing this later means a painful rewrite. 4. Weak payment handling Handle failed payments, retries and duplicate events from day one. Missing this leads to lost revenue and angry users. 5. No simple tracking Track signups, activation and cancellations from the start. Without it, you guess why people leave. What cost you the most time when building your MVP?   submitted by   /u/Swimming_Year5735 [link]   [comments]
