There is no 100% bug-free software.
No matter how professional you are, it's impossible to develop the perfect application without bugs, but that's something you can aspire to. You should understand that testing the application once before the release is not enough. It is better to start testing software or application as soon as possible in the early stages of development. Thus, you can save money and time to fix bugs.  
If you do not have a QA team or software testing department in your company, you need to hire specialists from outside. I hope this article helps you to choose the best software testing company.
Software testing companies can also offer the following services:
  • Manual and Automated Testing Services for Web applications;
  • Manual and Automated Testing Services for Mobile applications;
  • Load, Performance, Stress Testing Services;
  • etc.
While a decision had not yet been taken, there's something else you should know. 
Paying attention only to those aspects which are necessary, you have an opportunity to get a quite complete initial idea about the software testing company, you’d be working with. So I recommend you to put your mind to:
  • if they have the knowledge of different industry-specific;
  • experience and skills of the software testing team;
  • if the company support long-term relationships with their customers;
  • if the company is complying with stringent timelines and any changes to technology;
  • what a variety of types of software testing services the company has;
  • what types of frameworks, technologies, and methods the company uses;
  • discussing with candidates the strategy and ask them all about software testing and their methods;
  • how do they approach the issue of security.

How to choose the best software testing company

Another crucial factor in choosing the best software company is reviews. You can find reviews from real customers and clients on the websites of:
  • Clutch;
  • GoodFirms;
  • SoftwareTestingHelp.
Especially check out the first website – Clutch. Publishing review there is not the easiest task. Their representative calls and take an interview with clients over the phone and only then publish the review. You can really trust this source of information.
Finally, in conclusion, after you have implemented all the recommendations, make a shortlist of suitable candidates, and interviewing them. Ask them about their experience, case studies, working process, and QA team. Are they acceptable? Do they still suit to achieving your business purposes? Pick up the one that really does. I hope my recommendations and list of the best software companies were useful for you.
