Let me share some information about allocating receipts to sales invoices, enquiries46.
First, could you please clarify whether the receipt you mentioned is an attachment to an invoice? QuickBooks does not support automatic matching of receipts to invoices. Any additional information you provide will help me offer the most effective solution.
It’s possible that you created a recurring transaction with a receipt linked to it. After generating the initial invoice, you may have allocated the receipt to a different invoice, which could explain why the receipt appears linked to both invoices. When you check the audit log, this change is recorded as an indirect edit by the system, due to the recurring invoice you created.
Additionally, you can refer to this article for detailed information about indirect edits by the system in your audit log: Use the audit log in QuickBooks Online.
Moreover, I've added this article as your reference for receiving invoice payments in QuickBooks: Record invoice payments in QuickBooks.
