How to record invoice payments correctly

orienzk1_

Hello, I issued a few receipts for clients that are a single receipt for multiple payments within a year. In order to do so, I had to create an invoice then mark them as paid, but that created duplicate payments, and they cannot be merged since they are of different amounts (i.e. 5 payments of $200= one $1000 receipt.) I realized I should have issued 5 receipts for $200, but can't go back to change them now (although will do going forward). Can I just simply delete those invoices even if the clients used them for their tax filing purposes? Thank you!
