There's a lot of people wondering why the stage of QA and software testing is so necessary, isn't it easier to create at once a website, an application, or software without errors and defects?

Errors and bugs occur as a normal part of the development phase. By adding new functionality, a developer always is far from able to predict how it will influence the behavior of already existing tools. Well, that's where QA companies come in. Performance errors in hundreds of features are hard to detect and debug; therefore, development requires dynamic quality assurance testing services for identifying and debugging errors.

If we are talking about the development of e-commerce, Saas systems, mobile, and web applications, you shouldn't underestimate the importance of QA. You need to pay close attention to all the details. Otherwise, future users of your app or customers have to deal with the problems, which will undoubtedly spoil their experience of working with you. Moreover, some bugs cannot be corrected at all, and that, in turn, could lead to a loss of consumer confidence and loss of the company's reputation. Everything needs to be done right, and you are not afforded the luxury of making such mistakes in the current competitive environment.

So, if you decide that it's time to outsource the testing services, the next question is who entries this vital responsibility to. And if you are not going to create an in-house QA team, then you will need QA outsourcing companies. According to statistics, more and more companies are outsourcing some or other IT services for obvious reasons:

Quality assurance companies must possess technical tools and gadgets that are imperative for the testing of your software.
The region/country where the QA company is located is also a matter for most business owners: taxes, average rates, level of English. In some countries, QA services are cheaper and have poor quality, in other - more expensive but take more time.
Also, you should pay attention to their experience: how many years in the market, in which industries they worked, etc.
