Of course you can! I'll be happy to help with this. QuickBooks Online offers a flexible platform that lets you manage your financial operations quickly and efficiently. To undo a payment received entry, follow these steps:
Select Sales from the left menu
Select the All Sales tab
Select the Payment you wish to undo
Select More from the bottom menu
Select Void or Delete depending on your needs. Keep in mind that:
When you void, you only zero out a transaction. You can still open a voided transaction and see important details like customer or supplier name, transaction date, and transaction number.
When you delete, you permanently erase a transaction and its trace from your books. The only place you can check some details of a deleted transaction is on Audit Log.
Select Save and close
