Web Development Review from Griffin Joliboix
The team at Genetech did a great job helping us get our website back on track when updates were pushed through that we were unaware of. These updates caused implications that were problematic to our website performance at the most crucial time of the year for our sales, and their timely work helped out tremendously.

Bintime Reviews & Testimonials

Software Development Review from Oksana Pozhydaieva
We brought Bintime in to add senior full-stack capacity to one of our engineering teams at HelloPrint. We're a Dutch online print marketplace working with 300+ production partners across Europe. We were already working with other suppliers, and Bintime stood out by providing two full-stack developers who integrated smoothly into our feature teams. They worked alongside our engineers across our Node.js, Vue and React stack, contributing to feature development, bug fixes and ongoing maintenance, while keeping up with our fast, roughly weekly delivery cycles. Both developers stayed throughout the engagement, which made a real difference in terms of continuity. A solid, low-drama staff-augmentation partner.

eCommerce Development Review from Jelena Falatov
I'm happy to recommend Bintime based on our experience working together for more than 15 years. Throughout our collaboration, Bintime has been a trusted long-term development partner, supporting the delivery and continuous evolution of business-critical digital solutions. Their engineers work closely alongside our own teams, taking ownership of core business capabilities and contributing to long-term product development rather than isolated projects. What has consistently stood out is the quality of the people. Bintime has provided technically strong, dependable, and collaborative engineers who integrate naturally into our teams, take ownership of their work, and adapt well to changing priorities and technologies. Over the years, they have earned the trust to work on some of our most important products and services. The partnership has been built on trust, openness, and a shared commitment to solving problems together. As our engineering practices, technologies, and organization have evolved, Bintime has evolved alongside us. They have consistently approached change with professionalism, flexibility, and a genuine willingness to improve, making them a trusted extension of our engineering organization. Based on our experience, I would confidently recommend Bintime to organizations looking for a reliable software development partner with strong technical expertise, a collaborative mindset, and the ability to build long-term partnerships based on trust.

Software Development Review from Martijn J. Hoogeveen PhD
We have a long term relation with Bintime for providing software development services and resources to our core team. The team works in biweekly sprints, and the predictability and quality of the results are high. Which is necessary for a mature business relying on the quality and stability of our online services. The team participated into developing an MCP server as well for enabling us to be AI ready.

Briana B's Review Sourced from Google
Spams via email but also somehow got a hold of my phone number. They call every single day and leave a long message that I cannot understand because of the accent. How is annoying your potential clients to death a viable business model? Go away. Ignoring you 40 times CLEARLY means I'm not interested.

Frequently Asked Questions About Software Testing Companies
What services do software testing firms provide?
Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable.Â
Core services include:Â
- Functional testing Â
- Performance testing Â
- Security testing Â
- Usability testing Â
- Regression testing Â
- Automation testing Â
- Accessibility testing  Â
- Mobile app testing Â
- API testing Â
- Compatibility testing across devices/browsers Â
- Compliance testing Â
- Testing with artificial intelligence (AI) tools
- QA auditÂ
How much do software testing services cost?
Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche. Â
The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour. Â
Special software testing services such as QA audit goes from $5,000 to $25,000.Â
How can businesses know what type of software testing do they need?
Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:Â Â
- Core functionality issues: Use functional testing to verify features work as expectedÂ
- Unstable code or new features: Use unit testing for individual components and integration testing for modules working togetherÂ
- Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing featuresÂ
- Performance and load issues: Use performance and load testing to evaluate speed and scalabilityÂ
- Security issues: Security and penetration testing are commonly used across apps handling sensitive user dataÂ
- Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end usersÂ
- Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versionsÂ
There is also the option to choose between manual and automated testing. Â
Is automated testing more expensive than manual testing?
As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers. Â
So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment.Â
The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results. Â
Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features.Â
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:Â
- Code coverage: The percentage of the code that has been testedÂ
- Defect density: The number of defects found per unit of codeÂ
- Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective testsÂ
- Time to detect and fix defects: The time it takes to identify and fix software defects and software bugsÂ
- Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase Â
