Understanding how test credits billing works is an important aspect of using our platform. At our company, test credits are billed only when a candidate begins a test, not when they are simply invited to take a test. This means that test credits will only be deducted from your account once a candidate has actually started the test.

It's important to note that test credits are billed the moment a candidate enters a test, so it's important to make sure that you have sufficient credits in your account before allowing candidates to begin a test.

We hope this helps clarify how test credits billing works at our company. If you have any further questions, please don't hesitate to contact us for more information.
