What is User acceptance testing (UAT)?
User acceptance testing is the final testing stage, where real users check that a system supports their actual work before it goes live. They follow realistic scenarios and confirm the results are correct.
Why it matters for your business
UAT catches gaps that technical testing cannot, such as a missing step in a real process, and gives the business confidence to sign off.
Before go-live, the accounts team runs a full month-end close in the new ERP's test environment and confirms the reports match.
