How do I delete a payment set against an invoice?

How can I delete a payment set against an invoice as I need to put incremental payments to match my bank records.

Hi bjbmach,
The money you received for that invoice must also been shown on one of your bank accounts (petty cash, merchant account, current bank account and so on). Go just to that bank account in quickfile and click the red cross behind the transaction line. That will delete the payment and will show that invoice as unpaid.
