Why Hire Software testing services provider companies?

With the cut-throat competition in the technical market, Quality Assurance (QA) plays a predominant role in defining the success of any software. The quality assurance and testing of software is done to ensure that it achieves all the specified goals and technical requirements as it was supposed to. However, many organizations lack the required resources, skills, or qualifications to perform this unavoidable task.

That’s the major reason why companies prefer to outsource software testing services and get the required results. Outsourcing QA services to a professional 3rd party firm with expertise in this is one of the best business decisions. Partnering with a software testing company can accelerate the overall software development process. It is not just limited to speed, but it also fosters effectiveness and efficiency while maintaining the objectivity of the process. Here are a few main benefits of hiring a software testing services provider company:

1. Skills & Expertise:

It requires high experience and expertise for software testing. Generally, the in-house QA teams are not equipped with the latest tools, technological trends, and better practices. Proper testing requires a range of tools & tests to perform on various devices, platforms, and multiple parameters.

Thus, it becomes essential to outsource to the best software testing company that has a dedicated team of QA experts and relevant experience in the same. A specialist 3rd party, QA & testing company can bring all the essential skills and best-in-class resources for your project.

2. Cost-effectiveness:

Costing is another major reason to outsource the testing and QA requirements. You don’t need to maintain an in-house team and avoid various overhead costs like office space, salary, maintenance, insurance and others. Also, you have to pay the salary even if you don’t have any work for the QA team. Conversely, in hiring a software testing company, you pay only for what you want.

3. Efficient & Objective Assessment:

Most coders struggle to look at faults, errors, and problems objectively. However, when you choose to separate coding from testing using a third-party testing agency, you benefit from an unbiased evaluation of your program. An outsourced team will do an impartial audit to find all the existing issues that require attention.

4. Faster Results & Better Focus:

You can get faster results by outsourcing the testing stage of your software development process. This is because the development team can focus only on their part while the QA team simultaneously find the issues and the developers can resolve them later. Thus, the development team can focus only on the coding part. You can focus on other business parts like revenue, marketing, and others.

5. Complete Confidentiality of Code:

Using third-party software testing services means your company retains access to unique testing scripts and defect-free software without divulging code specifics.

You also don’t have to worry about infringing intellectual property rights when you use QA Outsourcing.

6. QA Automation:

Automated testing has been hugely popular as it ensures a seamless multi-device app experience for users. However, not everyone is skilled in automated testing, while a 3rd party testing company always has a team that can perform automated testing.

A professional QA tester always employs advanced test automation tools, bug tracking, and cutting-edge technologies for faster and more efficient testing.

How do you Choose the best software testing company?

Here are some QA factors to consider while you are outsourcing the testing responsibilities to a 3rd party software testing company:

1. Set your objectives & goals:

You must chart out your objectives and measurable goals for a robust outsourcing strategy. These goals will assist you in making critical judgments about crucial areas such as a project’s business value, outsourcing models, vendors, projects to outsource, and various risks to assume.

Goals, on the other hand, are events and functional metrics that assist management in monitoring progress, taking corrective action, and forecasting future performance.

2. Choose the way of outsourcing:

There are multiple ways of outsourcing the testing requirements, among which the three major types are:

Expert/Specialist QA Providers:

These companies have core services of QA and testing and don’t focus on any other service like development. They can be within your country or overseas.

IT Generalists

These are the QA service providers that offer QA service along with other outsourced services such as Web Development, Mobile App development, etc. You can ask them to develop your whole software or hire them for only the testing part.

Crowdsourcing providers:

These enterprises typically give out your testing activity to individual freelance testers. This model gives you the advantage of many different people conducting your tests under real-world conditions.

It’s important to consider your requirement for the type of QA solution that best fits your project.

3. Maintain a balance between quality and cost:

It is never a good option to opt for a company that offers the lowest cost for testing & QA because a lesser price doesn’t mean good quality at a reduced cost.

A company with good experience, a skilled team, and a diverse portfolio may charge a higher price but will also ensure the best quality to its client. Thus, it would be best if you did not consider the lowest cost as your criteria.

4. Flexibility and Adaptability:

Different software testing providers follow different testing processes and workflows. Generally, a third-party testing service provider follows the clients’ QA processes, which require flexible teams to offer excellent service.

Also, the company should be able to quickly learn and adapt to the new workflows while working with a new client.

5. Communication:

In technological development, communication plays an important role. The 3rd party must ensure meaningful communication instead of just inundating the customer with useless information.

Factors To Consider While Choosing the Best Software Testing Company:

Here are some important aspects to consider while choosing your software testing partner:

1. Past Experience:

The chosen software testing company must have a diverse portfolio showcasing its experience. There should be numerous projects or industries like your project or industry. It will be a plus for your software development as they could find quick and easy solutions from their similar prior experience.

2. Background:

There are a lot of companies in the market that boast of being the best software testing company. Firstly, we suggest choosing a software testing company from the above list. And if those don’t fit your requirements, then you must have a careful background of your potential testing partner. Many companies promise great rates, the best tools, the finest quality, quick turnaround time, etc. but most of these are gimmicks. You must scrutinise the vendor by its reviews, ratings, returning clients, list on popular platforms like Clutch, etc.

Also, you must check whether your chosen partner is doing the work itself or is further outsourcing to another vendor.

3. Service-level agreement:

A clear and well-defined SLA serves as a roadmap that guides the project from start to finish. It should preferably include the deadlines, milestones, project overview, communication pattern, and other critical factors.

SLAs serve as legally enforceable documents that protect both parties’ interests and serve as guidance for the processes to be followed in certain situations. Make sure that the SLA consists of the following items:

  • Process compliance
  • Entire reporting and project management timelines
  • Knowledge transfer
  • Core business know-how
  • Product quality measures include defect reporting, test case efficiency, etc.

4. Domain Expertise:

Even though the chosen testing provider has a lot of experience but needs more projects in your domain, it could be a disaster for your overall service delivery time. It will also affect the timeline and product quality. So, if your product is a website, and the testing company has all the skills but lacks Web app testing experience, it may not yield the right results for you.

5. Communication:

Barriers in communication due to any aspect like language, time zone, accent, or any factor may even create a complete roadblock in the work. That’s why a proper communication strategy is critical when choosing a software testing vendor. In simple words, an effective communication model must incorporate the following factors:

  • Escalation
  • Reporting
  • Issue Resolution

6. Data/Intellectual Property Security:

The vendor you choose should prioritize the security of your data and shouldn’t be shared with anyone. Make sure that the following outsourcing standards are being addressed while you are outsourcing to a QA partner:

  • Confidentiality contracts for employees
  • IP protection
  • ·Non-disclosure agreements

7. Robust Engagement Model:

If you are outsourcing for the first time, you should outsource smaller modules to analyze the quality of the vendor based on delivery, delivery timelines, quality of the bugs, etc. If all things are fine then you can move further with larger deliveries.

What process do top software testing services companies follow?

A top software testing company follows an effective QA process simultaneous with the software development process. It is generally 2-6 weeks, depending upon the project size. This process has four major steps, which many independent software testing services companies bifurcate into more steps.

1. Analysis of Software Requirements and Existing QA Process (if any):

In the first step, a QA consultant will understand your requirements (both functional & non-functional) to define the project’s scope and outline a path for establishing the QA process. If there is an existing QA process, the consultant will analyze it, evaluate its maturity level, point out flaws, and outline a new QA process.

2. QA process (re)design:

  • Check software requirements (functional & non-functional) to improve the development process consistency and completeness and future testing.
  • Analyze potential risks like timelines or any change in requirements, and define a risk mitigation plan.
  • Create a test plan and plan regular checks of design reviews to spot logical errors
  • Take a shift-left approach to testing and move testing activities closer to the beginning of the software development process.

3. Software testing:

This is the most important stage of testing. It includes:

  • Creating design scenarios and cases
  • Setting up a test environment and preparing test data
  • For automated testing, test scripts are written.
  • Execution of manual and/or automated tests
  • Adding automated tests into the CI/CD pipeline to speed up the testing process
  • The identified issues should be reported in a defect tracking system on a proper schedule.

4. QA process monitoring and improvement:

  • The flow of quality assurance process activities is monitored at all SDLC levels.
  • Gathering and evaluating key performance indicators (KPIs) (test coverage, requirements coverage, etc.).
  • Continuously improve the QA process (for example, modifying the test automation share, performing root cause analysis, and so on). 


How much does it cost to hire the best QA testing companies?

There are a lot of factors that decide the cost of hiring the best QA testing companies. Here we are considering the cost of only outsourcing companies, as the in-house cost of QA services is many times higher.

1. Level of Experience:

It is obvious that a beginner-level QA expert will have a low cost compared to a mid-level or senior QA expert team. Hiring a junior or senior QA team is not always necessary; it depends on the requirements. A basic web app will require the expertise of a junior QA, while if the project is quite complex, then only a Senior QA will be fruitful.

2. Location:

The geographical location plays a predominant role in deciding the cost. The salary of a QA living in Western countries, Europe, would be significantly higher than an equivalent skilled QA living in the Middle East or Southeast Asian countries. Here is a table of the average salary of QA experts in different locations:

CountryAnnual QA Expert Salary (in USD)
US98,305
UK78,000
Australia103,602
Germany65,894
France48,755
Netherlands51,106
Ukraine21,000
Poland23,486
Hungary26,587
India8,098
China30,873
Mexico21,076
Brazil27,451
Colombia13,120

In comparison to in-house, outsourcing is always at a lower cost. Here is an estimated difference:

Type of ExpenseIn-houseOutsourcing
Hourly rate$55$18
Yearly Rate$114,500$37,340
Cost of hiring$3,600$0
Benefits & Insurance$6,000/year$0
Taxes & overhead costs$9,000/year$0
Total$132,800$37,340

Thus, from a financial point of view, QA outsourcing companies are much better than an in-house testing team. These independent software testing services companies are affordable and can provide better services, trustable quality, and complete assurance.
