Sale Invoice Automatic Deliver

When you use the "Create Invoice" wizard on a sales order, a new choice appears in the invoicing method list: "Invoice the whole sales order + Automatic Deliver".

If you pick it, the module looks at the delivery orders linked to the selected sales orders. It first tries to reserve the stock for those deliveries. If every delivery can be fully reserved, it validates them immediately (using the standard immediate transfer confirmation), so the deliveries become done.

• If some products are not available, the delivery cannot be reserved and the module stops with an error message: "You cannot automatic deliver this order, some products are not available". No invoice is created in that case.
• If all deliveries are successfully validated, the invoicing method is switched to "Delivered quantities" and the normal invoice creation continues, so the invoice is based on the delivered quantities.

This affects the sales invoicing wizard (sale.advance.payment.inv) and works together with stock pickings (stock.picking) and the immediate transfer wizard. It is useful when you want to invoice and ship in a single action without manually validating the delivery first.
