Once the integration is enabled, Plastiq will charge your card automatically every time you process payroll. There are no other steps you need to take aside from running payroll as usual with ADP.
Please note, should your credit card decline or fail to process, you will receive an immediate alert from Plastiq. If your card is declined, that payroll run may need to be funded by other means. Please contact ADP if you would like to attempt a payroll reversal.
