FAQ
Questions we get about our QA outsourcing services
QA outsourcing, also called quality assurance outsourcing or outsourced software testing, is the practice of delegating your software testing (planning, execution, automation, and reporting) to a specialized external partner instead of building an in-house team. Done well, it delivers certified quality assurance expertise in days, removes fixed overhead, and keeps you in full control of quality.
It depends on scope, engagement model, and team size, but outsourcing is almost always lower than fully-loaded in-house QA once you count recruitment, salaries, tooling, and a device lab. See the true cost of building software.
