Software Testing Review from Brenda Collin FIH
Our busy online marketplace couldnt afford downtime or broken features after updates. BetterQA built and maintained a robust automated regression suite that tested checkout, search, user dashboards, and seller workflows. Their automation scripts run with every deployment and catch issues before users experience them. The improvement in deployment confidence and QA turnaround has been tremendous. Their technical skills in Selenium and Cypress, plus their understanding of business workflows, helped us scale operations without QA bottlenecks.

Applications Review from Denis Khorolsky
We worked with DevIT on a Shopify app for one of our ecommerce clients. The app handled product personalization, pricing rules, and personalized order data, while our team worked on the main Shopify platform and customer experience. The teams worked well together, and the client was able to launch the new feature without changing the existing store.

Small Businesses Website Development Review from Oleksandr Romanov
We worked together with DevIT Group on a financial operations platform for a shared client. Our team focused more on the core product and Python backend, while DevIT handled the infrastructure side using Node.js services built with NestJS and Fastify.
They worked on integrations, payment flows, internal APIs, notifications, and async processing between different services. A lot of the project depended on things working reliably in the background, and their part stayed stable even as new integrations were added later.
The collaboration felt pretty easy overall. Most discussions were direct and technical, without too much unnecessary process around them.

Small Businesses Website Development Review from Viktoriia Rekonvald
We worked alongside DevIT Group on a fintech platform for a shared client. Our team handled the blockchain layer, while DevIT was responsible for the web application built on a MERN stack.
They took care of the full application layer, including the React frontend and Node.js backend. Their part covered wallet connection flows, transaction tracking, and syncing on-chain data with the app. The way they handled API logic and off-chain data storage kept the system predictable even when blockchain confirmations were delayed.

eCommerce Development Review from Olha Yilmaz
We were searching for a partner because advertising alone can't deliver great results if the website isn't well-designed, user-friendly, and fast. That's why we chose to work with DigitalSuits, integrating their development services to enhance site performance alongside our advertising and SEO optimization efforts.
DigitalSuits exceeded our expectations. They redesigned the entire store to create a modern, responsive interface, developed a dynamic product configurator that enabled real-time customization, and optimized the sites performance for faster loading times. As a result, our client saw an increase in engagement rates, a 33% reduction in page load times that led to lower bounce rates, and a 25% boost in average order value. DigitalSuits' project management was exceptional, they responded quickly to the clients needs and kept us informed throughout the entire process.

eCommerce Development Review from Kateryna Sheremet
We needed a website for selling something special like experiences. As it was not a simple Shopify functionality, we chose DigitalSuits company as a Shopify expert. With their help, we created an e-commerce solution to sell experiences. Before the development process, DigitalSuits implemented all documentation covering the business requirements, guides on mockup creation, and product functionality. DigitalSuits experts know how to support and provide further improvements to our website.

eCommerce Development Review from Andrey Ryabuhin
Our client asked DigitalSuits to help with Shopify store development. To do so, the company was responsible for website design and development, and post-release maintenance and support. The company provided us with a team of 3 developers, 1 UI/UX designer, and a Project Manager.
To help increase brand awareness and make the E-Commerce platform as useful as possible, DigitalSuits added the FAQ section, Blog and About pages, custom features like bundle creator, and a User Profile page.

Heres the translated comment:
Comment:
Great job! The application looks intuitive, with a modern design and smooth user interface. The functionality is implemented at a high level: convenient specialist search, a transparent booking system, and a clear service payment structure. Additionally, I want to highlight:
1. Performance: The app runs quickly and without lags, leaving a positive impression on users.
2. Usability: The navigation logic and functionality are user-friendly for both clients and specialists.
3. Code: If the internal code is written with the same care as the external interface, its a testament to your professionalism.
If there are any upcoming updates, consider:
Adding ratings/reviews for specialists to build client trust.
Integrating reminders through push notifications or email.
Thank you so much for your contribution to the project!

Mobile App Development Review from Chelsea Husemann
In the first week of the launch, our internal team was happy with the app. Our user metrics and revenue are both going up and to the right, which is an early indicator of success. Weve only been up for about a week and a half, so its also still a little early to tell.
But, the app is more convenient. Users can use it to play games to get more entries into the sweepstakes. Retention numbers are solid, the artwork is fun, and everything is suitable for our demographic.
Wed been struggling with Google penalties at the time, and my consultant helping me with the issue said he was impressed that we made as much financial headway with the app as we had.
They were steady, consistent workhorses, setting a nice pace for the effort. We had a dedicated team, and the resource management was great. Their price point wasnt the most or least expensiveit was fair.

Mobile App Development Review from Andre Budinarta
The measurable outcomes from the project were highly impressive and demonstrated significant progress and success. Our website traffic increased by 50% within the first three months of launching the revamped site, leading to a noticeable boost in lead generation and inquiries. The mobile app received positive feedback from our clients, who appreciated the intuitive user interface and quick property search functionality.
What impressed me most about EB Pearls was their ability to understand our specific needs and translate them into a polished and functional digital solution. They took the time to conduct thorough research on our target audience and industry, resulting in a website and mobile app that perfectly aligned with our brand identity. Their attention to detail, creative problem-solving, and commitment to delivering high-quality work were truly exceptional.

Claim to be experts in Magento 2 dev. Had a meeting booked with them for nearly a week. Called minutes prior to meeting saying they don't do any Magento development work whatsoever.
Never a great look when a website developer can't even maintain the accuracy of their own website.

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.
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.
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.
Special software testing services such as QA audit goes from $5,000 to $25,000.
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:
Core functionality issues: Use functional testing to verify features work as expected
Unstable code or new features: Use unit testing for individual components and integration testing for modules working together
Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing features
Performance and load issues: Use performance and load testing to evaluate speed and scalability
Security issues: Security and penetration testing are commonly used across apps handling sensitive user data
Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end users
Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versions
There is also the option to choose between manual and automated testing.
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.
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.
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.
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.
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:
Code coverage: The percentage of the code that has been tested
Defect density: The number of defects found per unit of code
Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective tests
Time to detect and fix defects: The time it takes to identify and fix software defects and software bugs
Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase
