How much do CRO agencies typically charge?

CRO pricing varies a lot depending on the agency, project size, and scope of work. A smaller project or audit might start around $2,000 to $5,000. Ongoing monthly retainers for more in-depth testing and support typically range from $5,000 to $15,000 or more. Some CRO agencies work on performance-based models, charging based on the results they deliver. Others charge hourly or per test. Before signing anything, get clarity on what’s included: strategy, testing, design, dev work, or just recommendations? A good agency will be transparent about costs.
