Software development remains one of the keys to the companies’ strategic success. Planning, designing, and creating an app that will meet the needs of consumers is a huge, time-consuming process, and it requires a team of professionals from an outsourcing company, many resources, and plenty of testing.
The testing part can give businesses a real headache. Having an in-house QA team might be a good idea for large companies, but this decision is extremely costly. That’s why more and more people choose IT outsourcing for their projects. True, turning to outsourcers is a smart choice, but an inevitable question pops up: how do you choose the most suitable company?
Follow the tips below, and you’ll find all the answers you need.

8 Factors to Consider When Choosing A Software Testing Company
Important decisions should be made after thorough consideration. To choose a reliable software testing outsourcing company, you have to devise a list of key features that matter most to you. Fact-check each company against it and make certain your list mentions the following factors.
Proven Certifications for an Outsourcing Company
A respectable outsourcing company that delivers software testing services must hold internationally recognized certifications. The testers must be ISTQB-certified — this will guarantee that they are actual professionals whose practical experience has been verified by the international board.
Another important certificate to look out for is ISO 27001. It’s the standard ensuring the specialists’ adherence to information security principles, something you need to make certain that your product-related info stays confidential.
The ISO 9001 for quality management is also a must. The outsourcing company you trust must check the work of its employees regularly to ensure it corresponds to the highest standards.
Range of Testing Services
Every business has different needs. To produce the best product, you’ll need experts who deliver the exact software testing consulting and outsourcing services that can help you achieve the results you envision. Here are the options you can consider.
- Automated and manual testing. First, the specialists run various scripts and do AI testing to catch potential issues or bugs. Next, human experts join in, removing every issue they encounter.
- Functional & non-functional testing. Functional testing is what you want done to make sure your software works as it should. Non-functional testing means going above and beyond your expectations, checking for even those aspects that might have never occurred to your team.
- Security and performance testing. Checking whether the software is safe and performs well is paramount to its future success; stress testing is a part of this process.
- Integration testing. Your users might want to integrate your software with some other apps or platforms. Professional testers must guarantee that every component works properly independently and combined.
- Mobile and web app testing. There are many devices and mediums through which clients can access your software — that’s why it’s essential to make it universally accessible.
Doing wholesome testing is the best solution for developers who want to achieve a 100% efficiency rate.
Verified Market Experience
Go for the companies with an established reputation in the area of outsourcing their software testing specialists. They might have more expensive rates, but the final result will be worth it. Don’t risk the safety and efficiency of your software — trust professionals who know how to test it properly.
Communication Strategies
How many account managers can the company you’re considering offer? What are the feedback deadlines and guarantees? Clarify all communication strategies well in advance. You won’t want to be stuck with no answers and reports for who knows how long.
Available Tools for an Outsourcing Company
It might benefit you to learn what tools your company is using to do software testing. How do they check mobile optimization? Do they use JMeter or something else to do performance evaluations? The more you know, the more informed your choice is going to be.
Security Protocols
The outsourcing company you select must sign the NDA agreement. In addition, they have to stick to the latest cybersecurity protocols, guaranteeing protection against all potential data breaches.
Don’t be embarrassed to clarify this issue — the safety of your software depends on it. The last thing you want is for your ideas to surface in the hands of your competitors.
The Pricing
Different companies charge different prices. Naturally, if you choose a firm capable of delivering top outsourced offshore quality assurance, their price tag won’t be small, so it’s a question of whether you can afford to work with the best experts.
Smaller businesses might have to look for cheaper options, and that’s also a possibility. The most common drawback of such scenarios is that the testing process won’t be as comprehensive, but it might be sufficient enough to meet your current needs.
Customer Reviews
This is the most obvious but the most underestimated part of the evaluation process. Before trusting any company to work with your software, check what its previous clients said. If you have trustworthy business connections, ask around — perhaps someone you know can recommend a good company.
