Reverse Invoices and Credit Notes
Invoice, Reverse Invoice, Credit Note, and Customer CN
A Reverse Invoice formally cancels an Invoice and remains under Invoices. A Credit Note is created without a source Invoice and is listed under Credit notes. Customer CN is a separate module for documents received from customers.
Reverse Invoices
A Reverse Invoice is created from an Invoice, remains under Invoices, and keeps the source document visible in its details.
Credit Notes
A Credit Note is created without a source Invoice and appears on the Credit notes tab. It can be copied, marked as Paid, or returned to Unpaid when those actions are available.
