QA Testing (Quality Assurance)
QA testing (quality assurance) is the process of checking that a product works correctly — across features, edge cases, browsers, and devices — before real users see it. It catches the bugs that erode trust when they slip through.
Why does QA testing matter to your business?
A bug a customer hits costs far more than one caught before launch — in trust, support time, and lost sales. QA is the safety net that keeps a product feeling reliable. Skipping it is a shortcut that customers pay for on your behalf.
At Nabee, QA is part of building and shipping, not an optional extra, and fixes after launch are covered under the Maintenance Plan. Because the same team builds and tests, quality is owned end to end.
A concrete example
An app used by 2,500+ musicians like Metro X has to work across many phones and situations. QA across those devices is what keeps the experience consistent instead of breaking for whole groups of users.

Common questions
- Is QA the same as usability testing?
- No. QA checks that things work correctly; usability testing checks that people can use them easily. Both matter.
- Does Nabee include QA?
- Yes. Testing is part of building and shipping, and post-launch fixes are covered under maintenance.
- Can't I just fix bugs after launch?
- You can, but bugs customers hit cost trust and sales. QA catches them before they reach anyone.
