      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      Mobile App Development Review from Mica Palmer

      They helped us solve issues. They designed an app for us.High level/quality of client attention and interaction. All communications, information exchages, and client servicing were well-conceived and well-executed. They kept me on my toes to provide them the information they needed from me. They kept excited about the project and, because of that, kept me optimistic and driving toward the success of my project. The culture of coaching and support they provide start-ups. They don't sleep well unless they know you have all the tools and chops to obtain success. I've never seen any other company provide such rich and valuable deliverables along with ingenious and compassionate client support. Kodevent is a beacon of know-how and wisdom in an otherwise dark ocean for any start-up that is hoping for success.

      We needed help designing the Frontend pages on my website. Also some design work. Everyday I would assign my Frontend developer some key tasks and deliverables. He would report back to me. An example of key deliverable he did was help design the logic of flow of grading when we have multiple types of questions. They were quick to respond and professional. They had great professionalism, good talent, and good support.

      Kodevent and their team were always great at communicating with our team. They worked very hard to finish tasks in the allotted time frame. When we had requests or changes, they were always quick to find a superior solution. Our project is still ongoing, but they are waiting on our side of things to complete and go live. I am appreciative of their great communication skills. They were always quick to respond and worked within our time frame.

      Software Development Review from Harshal Chhajed

      They have highly skilled support staff for faster resolution which leads to customer satisfaction. Also, it has many features including IoT and blockchain apart from regular software development. If there are any changes in the scope of the project at a later stage, it can prove quite costly and also difficult to accommodate last-minute client-side scripting changes. They are versatile, cost-effective, and offer quick customer support. They offer a very customized software development tool where business needs can be addressed. It is very cost-optimized and hence can help generate good returns for business investment.

      I had a great experience working with Tepia. Abraham, the Founder and CEO, was available, helpful, and actively involved throughout every stage of the process. Kimmy, my assigned project manager, was organized, responsive, and clear in her communication from start to finish. They anticipated potential obstacles before they became issues and approached everything with a thoughtful, solutions-oriented mindset. The team was consistently proactive, professional, and transparent. I truly appreciated their structure and ability to keep things moving smoothly. I would highly recommend working with Tepia.

      Mobile App Development Review from Robert Beknazarian

      Working with Tepia Co has been an exceptional experience from start to finish. They played a critical role in developing our mobile app for RELI, and I can confidently say they exceeded our expectations on every level From day one, Tepia demonstrated a deep understanding of both the technical and business sides of app development. They didnt just execute tasks they asked the right questions, challenged assumptions when needed, and helped us think through complex workflows in a way that improved the final product. Their team truly operates as a strategic partner, not just a development vendor The communication was excellent throughout the entire process. We always knew where things stood, timelines were clear, and any issues or changes were handled proactively and transparently. For a project as complex as ours involving pricing logic, user flows, financing options, compliance considerations, and scalability this level of clarity and responsiveness made a huge difference. What really stood out was Tepias attention to detail and commitment to quality. The app they helped build is stable, clean, intuitive, and built with long-term growth in mind. They were thoughtful about architecture, performance, and future enhancements, which is critical for a company like ours that plans to scale aggressively. They were also extremely flexible and patient as our requirements evolved (which happens in real-world startups). Instead of pushing back, they collaborated with us to find smart, efficient solutions that aligned with our vision and budget. If youre a founder or business owner looking for a team that: Truly understands mobile app development Communicates clearly and consistently Thinks strategically, not just technically Delivers high-quality, scalable work I highly recommend Tepia Co without hesitation. They have been a trusted partner in bringing RELI to life, and we look forward to continuing to work with them as we grow

      They provide consulting services for a healthcare service provider. Sidebench contributed their expertise to a comprehensive mobile application to make sure it would pass Apple Store requirements. Thanks to Sidebench`s input, the application launched on the Apple Store after the first submission. Sidebench`s response times were quick, and they were willing to accommodate a unique working arrangement. The relationship that we had was probably unique; most companies would push to do the development themselves. We only needed Sidebench`s know-how, and they were willing to accommodate us.

      Software Development Review from Lori Feld Oakley

      Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

      I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Hiring Guide: How to Choose the Best Software Testing Company in the US

What do the best software testing companies in the US do for businesses?

Software testing benefits

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%).

How to choose the best company for your business?

To choose the best US software testing company for your business, evaluate its expertise and experience against your requirements. Here are some steps to guide you:

  1. Define testing requirements
    Outline current software issues, testing goals and priorities, project scope, compliance requirements, budget, and timeline.
  2. Search for relevant experience
    Evaluate case studies and client references to find a company familiar with your industry-specific requirements, tech stack, and testing coverage and methodology.
  3. Conduct due diligence
    Assess the company’s certifications, vendor partnerships, awards and recognitions, and client reviews to confirm it’s trustworthy and credible.
  4. Issue a request for proposal (RFP)
    Provide a detailed project brief illustrating your business's current predicaments, so that the company can provide an accurate quote that aligns with your needs.
  5. Schedule a consultation
    Meet the team who’ll work on your project and request sample reports or pilot tests to further gauge project fit.
  6. Make your decisions
    Beyond technical proficiency, select an agency that aligns with your values and is capable of supporting your growing needs with flexible team sizes and service levels.

What questions should you ask a US software testing firm before hiring?

Before hiring a US software testing firm, consider asking these questions:

Relevant Background

  1. How familiar are you with our industry-specific requirements? What deliverables can you provide to help us comply with the regulations?
  2. Can you share projects similar to our testing coverage, methodology, and criteria?
  3. What testing tools and frameworks do you use?

Services and Processes

  1. What is your software testing process — from discovery and planning to execution and reporting?
  2. How will you set up/manage test environments and test data?
  3. How do you balance manual vs automated testing? What are your criteria for automating tests?
  4. How do you handle access control, credentials, and confidentiality?

Relevant to Your Project

  1. What test types do you recommend for us, and why?
  2. What are your SLAs for triage, retesting, and regression after fixes?
  3. How do you measure quality and progress (coverage, defect trends, escape rate, release readiness)?

What are common mistakes to avoid when hiring a software testing agency?

Selecting the right testing partner requires careful evaluation beyond surface-level factors.

Common mistakes include:

  • Choosing based solely on cost: The cheapest option often leads to lower quality, missed defects, and costly rework. Organizations should evaluate "results per dollar" rather than "hours per dollar."
  • Failing to define requirements clearly: Vague project scopes lead to miscommunication, scope creep, and budget overruns. Clear documentation of testing objectives, success criteria, and testing entrance and exit criteria is essential.
  • Underestimating testing needs: Setting up additional testing environments and infrastructures beyond the agreed scope leads to longer project timelines and higher fees. One way to avoid this is to ask the company to conduct audits, so you can more clearly define the testing needs and strategies.
  • Neglecting long-term maintenance planning: Testing isn’t a one-time launch task. Without ongoing QA as the product changes, defects and security gaps reach users and become far more expensive to fix after release.
  • Ignoring communication and cultural fit: Testing teams need to integrate with development workflows. Time zone differences and communication barriers can impact collaboration quality.

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.

How to evaluate the effectiveness of a US software testing firm?

Per the State of Testing Report, these are the most common metrics businesses are using to measure a software testing team’s effectiveness:

  • Test coverage (56%): Compares how much of the software has been tested to determine the thoroughness of the testing process.
  • Defect metrics (54%): Measures the number of identified defects, organizes them according to severity, and the rate at which they’re identified.
  • Test execution metrics (45%): Monitors the speed, progress, and outcomes of running tests through test execution rate, test pass/fail/block percentage, and cycle time.
  • Escaping defects rate (34%): Tracks the percentage of defects or issues identified after a software has been released.
  • Test effectiveness metrics (25%): Identifies testing process performance in identifying defects and ensuring product quality before launch.
  • Test economics (8%): Determines if the business maximizes the return on investment (ROI) of software testing.

FAQs for Software Testing Companies

What services does a software testing company provide for your business in the United States?

They provide a comprehensive range of services designed to validate and improve software quality through systematic evaluation and advanced tooling. 

Core testing services include: 

  • Quality assurance and testing strategy: Audits software and defines testing scope, priorities, coverage, approach, and reporting. 
  • Functional testing: Verifies that software features work according to specified business and functional requirements. 
  • Regression testing: Detects unintended issues introduced by system changes and releases.  
  • Performance and load testing: Measures the application’s reliability and responsiveness during peak usage. 
  • Security testing: Identifies and resolves security vulnerabilities and tests against compliance and governance requirements. 
  • Usability testing: Assesses user experience, interface intuitiveness, and overall accessibility of the solution. 
  • Integration and API testing: Validates how different system components and third-party services work together. 

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.  

How much does software testing cost?

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: 

  • Critical systems and highly regulated industries: 40%-50% 
  • Enterprise applications: 25%-35% 
  • Consumer-facing applications: 15%-25% 
  • Mobile applications: 20%-30% 

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. 

Are there any additional costs to consider when working with US software testing agencies?

Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA: 

  • Tooling and platform fees: Software license or subscription fees for device farms, performance testing platforms, and security scanning tools may be billed separately from the company’s overall rates. 
  • Device/browser lab coverage: For tests that require broad compatibility coverage, costs can increase based on access to real devices, operating system versions, and browsers.  
  • Scope growth: New testing requirements, additional integrations, new platforms (mobile/web), or expanding acceptance criteria often require a change order. 
  • Additional test cycles: Extra rounds of re-testing and regression tests beyond what’s defined in the service level agreement (SLA) incur additional costs. 
  • Defect remediation effort: Fixing defects is often outside the testing scope and is billed as an additional engineering or development fee. 
  • Compliance and security deliverables: If you require additional formal evidence (e.g., audit artefacts and traceability) or expanded security testing, expect incremental charges. 

How long does software testing usually take?

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 
(e.g., Landing platforms)

 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. 

What industries do US software testing firms typically work with?

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: 

  • Tech: 35.2% 
  • Finance and insurance: 16.9% 
  • Others: 12.7% 
  • Healthcare: 10.9% 
  • Business and information: 4.5% 
  • Retail: 4.1% 
  • Marketing: 3.7% 
  • Transportation: 3% 
  • Government: 3% 
  • Gaming: 2.6% 
  • Education: 1.9%
