Record invoice payment
Record money received from a customer against one or more open invoices.
MCP tool myob_write → record_invoice_payment
write Confirm
Records the payment as Sales > Record invoice payment does and returns the amount applied to each invoice with its new balance and status. A payment that settles an invoice in full closes it; a smaller amount leaves it open. An amount above the open invoices makes MYOB create a customer credit, so check the balance with get_invoice first. Payments already reconciled cannot be changed later. By default you confirm each call; you can switch that off for this tool.
