      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.

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 weeks2-4 weeks
Mid-sized builds 
(e.g., Fully customized mobile apps)
16-40 weeks3-4 months
Large builds
(e.g., Multi-module platforms)
36-144 weeks6-12 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%
