My relationship with Troy Web Consulting began in 2019, and I am very proud to say it still continues. Their experience and expertise is second to none, and their incredible customer service makes communication between you and your project manager and the team something you look forward to. It has truly been an enjoyable experience growing my company with the help and abilities of such a great group. A special thanks goes out to Anthony and Mark, two of the best to work with.
Caring Gene's Review Sourced from Google
Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

ISBX is a very professional and talented web development company. The overall experience I had with them in the redesign of our website was outstanding. They were extremely creative, provided viable options at all junctures, and delivered on time and on budget. ISBX also provided a very hands-on, and professional team who understood our need for brand engagement and outreach to a new audience with our website refresh. The team also optimized the new site for mobile usage which was very important to us. ISBX successfully executed our complex project efficiently, with excellent communication and attention to detail at every step. I wouldn't hesitate to work with them again.
Kim Farley's Review Sourced from Google
ISBX helped us from concept to launch without any issues. They were communicative, patient, and able to quickly implement solutions to project changes that came up along the way. We appreciate that they took the time to hold our hands with explanations and detailed questions to make the process as stress free as possible and to get a good understanding of our product.

I've been a client of ISBX for nearly three years. They are hands down the best development firm I have ever worked with. They are on budget and on time consistently. They are trustworthy, highly communicative, and very versatile. Nothing is in the "too hard box" for them.

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]!

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)

Web Development Review from Undisclosed
Aristek Systems developed, tested, and released a new website for an e-commerce development company. The team utilized Ruby on Rails, Elixir, Phoenix Framework, JavaScript, GraphQL, PostgreSQL, and AWS. Aristek Systems was able to deliver a fully functional software, much to the client's delight. The team was highly communicative, and internal stakeholders were particularly impressed with the vendor's professionalism and attention to detail.

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.

They help businesses reduce release risks, enhance user experience, and strengthen security posture by ensuring that the finished solution meets industry and business-specific standards.
In fact, research found that fixing bugs before product release results in 6.5x less cost than resolving the issue after launch.
Moreover, automating load and performance tests can accelerate the regression testing timeline by up to 90%.
Gartner’s study also found that the top reasons that organizations use automated testing are to improve product quality (60%), accelerate deployment speed (58%), and enhance department agility (41%).

Common mistakes include:
When asked about the most significant challenges to automated software testing deployment, struggles with implementation (36%), automation skill gaps (34%), and high upfront costs (34%) were among the most commonly reported.
Per the State of Testing Report, these are the most common metrics businesses are using to measure a software testing team’s effectiveness:
Rated 4.8 on Google and 4.7 on Trustpilot, DesignRush Agency Directory is a reliable resource for finding software testing companies in the United States.

Core testing services include:
In addition to these services, software testing companies implement a mix of manual (often for exploratory and user experience-focused scenarios) and automated (repeatable checks throughout the development cycle for speed and consistency) testing models.
Software testing costs about 15%-25% of the development costs or 23% of the IT budget. In terms of hourly rates, US software testing companies charge an average of $100-$250 per hour, with more complex systems or specialized tests going beyond $300/hour.
The final rate will depend on solution complexity, testing coverage, quality requirements, project timeline, and current technical debt.
Here’s how much software testing costs as a percentage of the software development budget:
In practice, basic one-time testing projects, such as a website penetration test, cost approximately $5,000-$10,000.
On the other hand, continuously evolving software solutions that require regular comprehensive testing can fetch between $20,000 and $70,000+ per month.
Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA:
On average, software testing takes around 20%-40% of the total software development time. However, the final timeline will depend on infrastructure complexity, test scope and methodology, and quality requirements.
Here’s an approximate software testing timeframe based on the typical software project schedules:
| Full Release Schedule | Software Testing Timeframe | |
Small software builds | 12-24 weeks | 2-4 weeks |
| Mid-sized builds (e.g., Fully customized mobile apps) | 16-40 weeks | 3-4 months |
| Large builds (e.g., Multi-module platforms) | 36-144 weeks | 6-12 months |
Notably, software testing is often integrated into the software development lifecycle (SDLC). As such, it’s common to see QA and testing done in 1-2-week sprints rather than a separate stage altogether.
US software testing providers work with a wide range of industries, as all digital solutions need to be tested in some capacity. However, these are the sectors that quality assurance (QA) and testing experts work in based on the State of Testing Report 2025:
