Send invoice
Email an invoice to the customer with the PDF attached.
MCP tool myob_write → send_invoice
write Confirm
Sends the invoice from the Share menu, Email invoice, to the address on the customer card unless you pass to. Attachments total up to 25MB. If the customer has no email address and you pass none, the call fails and sends nothing. The invoice then shows Emailed in its activity history. By default you confirm each call; you can switch that off for this tool.
