Create a credit note
Reverse a posted invoice with a credit note.
MCP tool odoo_write → create_credit_note
write Confirm
Uses the Credit Note window of the invoice. In reverse mode the credit note is a draft prefilled from the original invoice. In reverse_and_new mode it is validated, reconciled with the original and a new draft invoice is opened. If money goes back to the customer, register that payment afterwards. By default you confirm each call; you can switch that off for this tool.
