One expensive surprise.
A discount disappears when a declined payment is retried.

LESS GUESSWORK AT RELEASE TIME
Test what matters.
Explain what happened.
Your checkout, onboarding, permissions, and core workflows deserve more than a generic click-through. We agree what success looks like, then test against it.
02
Build the checks
Create or improve approved browser and API tests using controlled staging data and explicit expectations.
03
Review the evidence
Investigate failures and distinguish suspected product issues from test or environment problems.
04
Improve the release
Give engineers reproducible findings, show untested scope, and measure checking effort before and after.
EVIDENCE YOUR ENGINEERS CAN USE
A finding should
start a fix.
Not another meeting.
Every reviewed issue should explain the steps, expected behavior, observed behavior, and the environment tested. A likely cause stays a hypothesis until it is verified.

WHERE SENTINEL FITS
A service today.
A platform taking shape.
Estech Autonomous QA is delivered by senior QA engineering. Sentinel is our developing platform for risk-based test selection and evidence reporting.
The prototype runs controlled Playwright checks and produces real local evidence. Repository integrations and managed customer infrastructure are being developed. Your pilot is a scoped engineering engagement, not access to a finished self-service SaaS.
