When an invoice has been sent to a customer it could happen that the customer disagrees with the invoice due to incorrect amounts, discounts, products, etc.
Depending on whether the customer or vendor has already paid the invoice there are several options to handle this situation:
The customer has not paid the invoice yet
The customer has paid the invoice and allows offsetting against other (possibly future) invoices
The vendor has not paid the invoice yet
The vendor has paid the invoice and allows offsetting against other (possibly future) invoices
