Use this as a working checklist, not a polished report. Open the page, flow, or system you want to review, go through each section, and write down what is broken, unclear, slow, missing, or hard for a customer to complete. If a check does not apply to your situation, skip it. The point is to find the few issues that would make the biggest difference before you spend time or money on SaaS & MVP Development.
Start with the sections closest to revenue or lead flow. If something is broken, unclear, or untracked, write it down before jumping into a rebuild.
Product State
A SaaS MVP can look close to done while the core flows are still unreliable. Start by testing the product like a real user.
Create a new account from scratch.
Complete onboarding without internal help.
Use the main feature the product is supposed to sell.
Test upgrade, payment, cancellation, and account settings.
Write down every place the product blocks or confuses the user.
Codebase
The rescue plan depends on whether the codebase is understandable, deployable, and stable enough to improve without creating bigger problems.
Confirm the project runs locally.
Check environment variables and setup documentation.
Review authentication and role handling.
Review API structure and database access patterns.
Check whether deployments are repeatable.
Payments
Subscriptions and payments are often where MVPs become fragile. Billing needs to work before serious users arrive.
Test subscription signup.
Test failed payment behavior.
Test cancellation and plan changes.
Check webhook handling.
Confirm access changes when billing status changes.
Admin Tools
A founder should not need a developer for every customer support issue. Basic admin visibility can prevent daily operational pain.
View and search users.
Check payment and subscription status.
Review key customer activity.
Handle common support actions safely.
Log important changes where useful.
Launch Risk
Before adding more features, stabilize the flows that affect trust, payment, onboarding, data, and support.
Fix broken signup and login flows.
Fix payment and access mismatches.
Fix errors in the main product workflow.
Add basic error handling and useful empty states.
Prepare a short launch checklist and rollback plan.
Payment problems should not be guessed through. If customers are charged but access is wrong, webhooks are failing, renewals are out of sync, or checkout errors are affecting revenue, get technical help before more transactions pile up.
Successful payments are not updating orders, accounts, or subscriptions.
Customers are charged but cannot access what they paid for.
Webhook errors, duplicate events, or failed renewals are showing up.
Staff are manually correcting payment status too often.
This resource is written for people who need practical checks, not a long theory document. It should help you decide what to fix, what to ignore, and what needs a deeper review.
