How to monitor partial payment

Dear All:

In my case, I always pay more money for original AR because I forgot partial payment had been done before. How I monitor AR overpayment when past partial payment exist?

Thanks for the help suggestion first. Sorry for error description above.

1.first for specific overdue analysis policy of company, we use partial payment.

2.And then the question comes. According to contract item, we send invoice to customer only once and receive payment in several step. Each time income received, we use partial payment to clear the AR (to relate payment with original AR). But one customer may have some contracts with us, it always pay for all contract in certain amount at one time. We shall manually divide amount for each contract. If user forgot one contract was paid partially before, he may clear the AR totally at sencond time and then the first payment will still outstanding in open item. Finally we can find many partial payments received but can't refered to any invoice.

So we are finding a way to control AR clearing to check whether partial payment exist and if the total amount is over original invoice it couldn't be cleared.

Thanks to give me some suggestion.
