Save a sales invoice as Unfinished and return the totals.
POST https://cotlet.dev/api/v1/procountor/partners/{partner_id}/sales-invoices
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.
