How do I void a payment recorded on an invoice?

"Payment voided" / "The invoice is open again for the amount it paid." The balance comes back, and the bank balance and receivables go back to match. On an owner-collection invoice, the management fee taken from that payment is reversed too.

If that payment had paid an online invoice in full, the online payment link stops working; record later payments by hand.

• "This payment is matched to a bank transaction. Unmatch it in the bank feed first, then void the payment." with Open in Bank Feed.
• "This collection was already paid out to the owner, so it can't be voided. Void the owner payout first." with Open owner payouts.
• "This invoice was written off, so its payments can't be voided."
• A closed period: "Couldn't void the payment".
