Finding a trustworthy software testing company is not piece of cake. It may take weeks, and it is guaranteed to cost you some efforts and nerves. Yet, it’s not like you can release your software solution without proper testing done. Users become less forgiving when it comes to less-than-perfect user experience and bugs. What is more, if you are determined to update and improve your software, you will need to cooperate with a QA company on a regular basis. And if you don’t want to switch to another company in a rush because you need to meet deadlines, you’d better make sure your first choice is the optimal one.
