QA and software testing companies check that your website, app or software works before your users find the problems. Services include manual testing, automated test suites, performance and load testing, mobile device testing, accessibility checks and testing of APIs and integrations.
The best results come when testing starts early and the testers understand how your users work. Ask how they write test cases, which tools they use, and how bugs are reported, prioritised and re-tested.
What to check before you hire
- The kinds of testing they offer: manual, automated, performance, mobile, API.
- Sample test plans and bug reports with client details removed.
- Tools and frameworks they use, and whether automated tests are handed over to you.
- Devices and browsers covered for web and mobile testing.
- How testing fits your release cycle and who signs off a release.

FAQ
Questions about qa & software testing companies
Why use an outside testing company?
Independent testers find problems developers miss and can add automated tests or device coverage your team does not have.
Manual or automated testing?
Both. Automation suits checks that repeat every release; manual testing suits new features, usability and edge cases.
What should a bug report include?
Steps to reproduce, expected and actual results, screenshots or recordings, the device and browser, and a severity rating.
