process for overpayment from customer

SOLVED

Hi everyone,

I 'd like to ask about the process to deal with overpayment for our customer.

we continually receive overpayment from our customer, eg double payment for one invoice...

Our current process is enter as unapplied payment if there is no other open invoice in the system for this customer and if there is one open invoice, we use the double payment apply to the open invoice and the rest of money will be entered as unapplied payment.

Problem we have here is normally customer does not realize we apply the overpayment payment to the next invoice, and later we will receive the payment for the next invoice as well... everyday we have lots of overpayment like this and after we apply the overpayment, another overpayment comes in....


Any suggestion to this process? what have you done with you ACCPAC system for this kind of overpayment.


Many thanks in advance!
