All Adaface plans are credit based. All credits you purchase are valid for 1 year from the date of purchase.
Here is how credits work:
5 credits for ready-to-go test
10 credits for custom test
1 credit per candidate invite (unused credits are refunded)
Example 1: You get 1 custom test made (10 credits) and invite 90 candidates (90 credits). That's a total of 100 credits used.
Example 2: You access 1 ready-to-go test (5 credits) and get 2 custom tests made (10 credits each) and invite 100 candidates (100 credits) to complete the test. That's a total of 125 credits used.
