To fix an overpayment
If you've overpaid an employee you can make an adjustment on their next pay, or if they have paid back the amount, record a new pay for the employee using the Process Payroll Assistant (Payroll command centre > Process Payroll).
Enter the adjustment as a negative (-) amount in the Hours or Amount columns of the category that was overpaid. Remember to zero out all the categories that you are not adjusting. The net pay amount should be equal to the overpayment, and shown as a negative amount.
Note that when recording a pay with a negative net pay amount, the payment method is automatically changed to Cash and the linked bank account for cash payments will be used. This can't be changed.
Can't record a negative pay? Yes, however, this feature is only available in the new AccountRight (not AccountRight v19).
