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.
Core Flow
An MVP does not need every feature, but the main user path should work without hand-holding.
Test signup and login.
Test onboarding from a new account.
Test the main product action.
Check empty, error, and loading states.
Confirm basic emails are sent correctly.
Launch Safety
Early users will expose weak spots quickly. Fix the problems that damage trust before inviting them in.
Check billing and access rules.
Review admin visibility for support.
Set up error monitoring or logs.
Prepare rollback or hotfix steps.
Write a short support response process.
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.
