A customer has overpaid on several invoices, I need to leave the balance on their account and not allot it to other invoices as yet. How do I do this?

Hi kim_h

Select receive payment on the invoice,on the payment page overwrite the amount displayed in the amount received field, on the right hand side, with the amount that was actually received from the customer, a credit/unapplied payment will be applied to the customers page, you can then apply this to future invoices, it will appear when you select receive payment on another invoice.
