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]!

Christine Terrill Founder at Zetya Pty
1.0★
eCommerce Development Review from Christine Terrill
We hired Selleo to do a redesign of our app. Poor communication, repeated missed timelines and a very poor quality of the small items that were delivered. Anna (Head of Business Development) ironically kept asking us if the "project was on track" and if we were "happy" with the project and despite our negative feedback did nothing to get the project back on track. We eventually fired Selleo after wasting $20k on this project. I would not recommend using Selleo.

Software Development Review from Rajeev Singh
We built a very comprehensive software that was complex in nature. Ideally, this requires either thorough understanding of accounting practices or a very meticulous approach of capturing the requirement. While Finoit's team had an analyst form finance assigned, what impressed me most(Being a developer in the past myself) was the latter part i.e. their project and development team's thoughtfulness in understanding all the aspects and getting back to us with intelligent questions.Highly impressed and recommend for their software development capabilities.

We recently worked with Geeks to do a scoping workshops/Solution Design for the development of a application for streamlining our reporting and surveying processes.The process from opening meeting to final wireframing was seamless. The knowledge and approach of the Business Analysts and the whole team were excellent, they listened, advised and offered thoughtful suggestions for improvements.The end specification for the application met and in many ways exceeded my expectations.Professional, friendly and smart. Great experience

Bradley Ebsworth-Willis's Review Sourced from Google
We recently completed a solution design project with Geeks, and I can not speak highly enough about the service we received. Geeks really are experts are making the complex appear (relatively) simple. Through a thorough and detailed solution design process, we created a prototype product that met all of our requirements. Geeks focus on producing visual representations of the product you are seeking - which is a far more efficient and helpful way of solution designing (as opposed to a written specification). Thank you very much for your support once again and I look forward to working together again in the future! Bradley (Associate Director)

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
