If software products are too slow, take a long time to load, or do not contain relevant information, people stop using them and choose other alternatives. This implies an urgent need for creation of a high quality software product, which will increase a company’s profits. In addition to the development itself, software testing is extremely important. After all, this is one of the most fundamental criteria for a successful software release.

Sometimes, due to a lack of resources within the company, QA and software testing is transferred to a third-party companies, that has relevant expertise and guarantees software testing services based on proven and effective methodologies.

The following is a list of the best software testing companies that are rightfully considered the leading providers of first-class services for QA and testing any software.
