      Mobile App Development Review from Dr. Lesley Kirkpatrick, MD

      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

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%
