Flow-Guard
A human-led QA review for SaaS products before launch, followed by automated regression runs once the product is live.

Overview
Flow-Guard is a service, not a software product. Before launch, a QA specialist goes through the product the way a first-time user would: signing up, running payment flows and checking it on several devices. After launch, automated regression tests cover critical flows such as sign-up, onboarding and checkout on every deploy.
Problem
Automated checks confirm that what was specified still works, but they rarely notice confusing flows or UX problems a first-time user hits. Small teams shipping fast often have no one to do that pass before going public.
Who it's for
Founders and small teams preparing a SaaS product for public release.
Key features
- Pre-launch manual review of the whole product, including payment flows and multiple devices
- Automated regression runs on every deploy after launch
- Pre-launch and post-launch work can be combined in one engagement
- A short application form with labelled fields and announced errors; scope is agreed after the product has been reviewed

Challenges & trade-offs
- One validation schema shared by the browser and the server, so the application form gives instant feedback but is still checked again where it counts.
- A fast, accessible one-page site: fields tied to their labels, errors announced to screen readers, and scroll animations that fail open so content is never hidden.
