Checks completed in a given month are charged via invoice on the first day of the following month. Onfido only charges for checks that are completed, so checks that have been initiated in a given month won’t necessarily appear on the next month’s invoice. If more than one check is being performed, the charges may be split across multiple invoices if the checks complete at different times.
