Designli Reviews & Testimonials
Mobile App Development Review from John Laporte
Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.
Mobile App Development Review from Brandi Heffner
Designli built our SaaS product from scratch, using AI to speed up development, with AWS and Cloudflare in the stack, and they also handle our hosting and maintenance. We had a working MVP in just 30 days and have kept adding features since. In the first 60 days they went beyond what we expected, largely because they took the time to really learn our business and our market. Coordination through Basecamp and Google Meet has kept everything organized.
Mobile App Development Review from Thomas Simmons
Designli took over app development and marketing for our driving school, with the goal of building a product we could eventually offer to other schools. Within two and a half months, the app was up and running in our own school. Their project management is excellent, and they push back constructively, thinking through what we actually need instead of building every request as-is.

I just want to express my deepest gratitude for all of your help. I can't tell you enough how much I LOVE the website. I think it's so beautiful, professional and elegant. I think it's one of the best therapist's website[s] on the market. :) Thanks to Jeanette and [the] rest of the team for their creativity and neat work and Irina for her incredible knowledge about SEO and resources! You guys rock! (Verified via email)
Web Design Review from Alyssa Brenke
Specifically, working with Ben was amazing! He was incredibly responsive and answered all my questions throughout the process of updating our website. Our original site was built roughly a decade ago (or longer) so we were in need of some streamlining and modernization. The team did just that and quickly! The first iteration was spot on for what we were looking for. Not to mention, they were able to launch quickly and without any interruption to our daily operations. Would 100% recommend [it]!
Web Design Review from George Shvaya
Irina and Ben from [eSEOspace] were a dream to work with! Not only did they turn[...]around work quickly, but their attention to detail is fantastic, as is their regular communication. I will definitely be reaching out to [eSEOspace] again in the future with more work! (Verified via email)

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.
Core services include:
- Functional testing
- Performance testing
- Security testing
- Usability testing
- Regression testing
- Automation testing
- Accessibility testing
- Mobile app testing
- API testing
- Compatibility testing across devices/browsers
- Compliance testing
- Testing with artificial intelligence (AI) tools
- QA audit
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.
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
