Guide
What a QA agency actually delivers
From manual testers checking new features before release to fully automated test suites that run on every code update, QA agencies cover the full range. The real value rarely comes from more tests, though. It comes from the right ones: tests that actually catch bugs before your users do, and that don't flag false failures on every small change.
What matters in your test strategy
Your test strategy should fit your product, not a generic template. Some applications mainly need interface-level tests, others get more value from tests at the API or component level. A good agency explains which test levels bring the most value for your project, rather than testing everything by default.
Integration into your existing development pipeline determines the long-term payoff. Tests that only run manually once a quarter catch bugs too late. Automated tests that run on every commit give you immediate feedback.
Test maintainability is often underestimated. Test code that breaks with every minor interface change quickly becomes a burden instead of a help. Ask about the test architecture, not just the number of tests written.
What quality assurance costs
€90 to €160 per hour is typical. Building test automation for an existing application costs €15,000 to €50,000, depending on the application's scope. Ongoing manual QA support is often billed by effort or booked as monthly capacity, starting around €3,000 a month for part-time capacity.
Typical QA projects
Building an automated test suite for a previously untested application. Manual quality assurance before major releases as an independent, external check. Performance and load testing ahead of an expected traffic surge. Test automation for mobile apps across multiple device types.

Frequently asked questions
QA agencies: questions and answers
What does building test automation cost?
€15,000 to €50,000 is typical for building automation for an existing application, depending on scope. Agencies charge €90 to €160 per hour. Ongoing manual QA support is often booked as monthly capacity, starting around €3,000 for part-time capacity.
Is test automation worth it for a small project?
Often not, for an application that changes rarely, since the effort of building it out outweighs the benefit. For software that's developed further on a regular basis, automation pays off quickly, because every later change gets checked immediately for unwanted side effects instead of needing manual retesting.
How many tests does my application actually need?
Fewer than most templates suggest. What matters isn't the count, but whether your application's critical flows are covered, things like the checkout process in a shop or the login flow. An agency that promises 100 percent test coverage right away is usually promising more than makes economic sense.
Does test automation replace manual testing entirely?
No. Automated tests reliably confirm that known behavior keeps working. Manual testing and exploratory checks, on the other hand, catch unexpected problems nobody thought of beforehand. Combining both approaches gives you the most reliable quality assurance.
