We worked with CIDT on building a web3 tax module for our platform. The team created the full backend: blockchain data processing, NFT and DeFi event detection, VAT logic, and reporting.

We partnered with CIDT to integrate a cryptocurrency payment module into a custom eCommerce platform we were developing for one of our clients. Our goal was to add a secure and seamless crypto payment option without disrupting the existing checkout flow.The CIDT team handled everything related to blockchain integration from wallet connections and smart contract setup to documentation and testing. Their work was well-structured, efficient, and fully aligned with our development process.A special mention goes to Ramil, CIDTs CTO, whose technical expertise and leadership were outstanding. He guided our team through the blockchain-specific parts of the project, explained complex concepts in simple terms, and helped ensure that the solution was both reliable and easy to maintain.All milestones were delivered on time, communication was smooth, and the final integration performed flawlessly. Within the first three months after launch, over 3% of transactions were completed via crypto payments, with a higher average order value than traditional methods.Overall, working with CIDT was an excellent experience. Theyre a professional, knowledgeable, and trustworthy team, and we look forward to future collaborations.

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:
