Lauren Sobin's Review Sourced from Google
The team at BLL went above and beyond. They took my app idea and designed/developed it with lots of thought and care. The planning and "sprints" were well organized and we kept on-target with frequent catch-ups & project management tools. Looking forward to launching the app to the public with their support.

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%).

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:
