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:

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:
