how to change a paid linked invoice to a different estimate

You can delete and recreate both the payment and invoice and link it to the correct estimate, @M Bader.

 

To begin with, if an invoice was paid but linked to the wrong estimate, QuickBooks Online (QBO) doesn't provide a direct way to change the estimate link after the invoice has been created and paid. To correct this, you'll need to delete both the payment and invoice, then create a new one linked to the correct estimate.

 

Here's how:

You can now create a new invoice linked to the correct estimate then re-enter the payment afterwards using the original payment date.
