Blockchain Review from Shubham Naliyapara
We worked with Solicy to build our decentralized application from the ground up and it was a great decision. Their team took time to understand our goals and users, helping us shape the product beyond just development.
They handled everything including clean and user-friendly design, secure and efficient smart contracts, seamless backend and frontend integration, and easy connection to popular crypto wallets. Security was a priority throughout the process.
Communication was clear and consistent. Solicy kept us informed at every stage and offered practical solutions whenever challenges appeared. They adapted quickly and made sure the project stayed on track.
Thanks to Solicy, our DApp launched successfully and runs smoothly. If you need a partner who truly understands Web3 and cares about quality, we highly recommend them.

Mobile App Development Review from Bruna Bison Franceschi
Solicy developed a blockchain based KYC mobile app for us and the result was exactly what we needed. The app allows users to verify their identity in a few simple steps and all data stays secure thanks to the blockchain layer.
The process is fast user friendly and fully compliant with regulations. Our partners and clients appreciate how easy it is to complete KYC now.
Solicy was very responsive throughout the project and delivered everything on time. Great experience from start to finish.

IT Services Review from Valentin Shtefan
We reached out to Solicy to help us integrate multiple third-party APIs into our platform, including payment processing, KYC verification, and real-time crypto pricing. They made the entire process smooth and stress-free.
The team understood our business logic fast and mapped out a clean integration plan. They connected everything securely and tested each API to make sure the data was accurate and stable. We now have a dashboard that pulls in live data, handles user verifications, and tracks payments all in real time.
Communication was clear, and their team stayed responsive throughout. Solicy also documented everything properly so our internal devs can manage updates later on.
If you need a team that knows how to handle real API work and not just write boilerplate code, Solicy is a solid choice.

Singh Alka's Review Sourced from Google
We are incredibly grateful to Webcom System for their outstanding work creating a website for our optical firm. The company owner and the team walked us through the procedure, were patient with our questions, and took the initiative to keep us on our timeline.
They presented us with a website showing a smooth new design and simplified management; in Chinese, there is an expression, 三百六十行，行行出状元, which means in every profession, there are only a handful of specialists. The team were just the professionals we needed for our website. They went above and beyond.
We recommend the Webcom system to companies looking for excellent, efficient, affordable web design.

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
