Create sales invoice
Save a sales invoice as Unfinished and return the totals.
MCP tool procountor_write → create_sales_invoice
write Confirm
Creates the invoice the way Save does in Invoice view. Procountor generates the invoice number on save. The invoice stays Unfinished: editable, not sent and not yet counted in tax reports. Returns net, VAT and gross totals and the due date calculated from the payment terms. By default you confirm each call; you can switch that off for this tool.
