The A/R reserve invoice allows you to issue invoices for warehouse items without deducting the items from the inventory. If you create a reserve invoice, SAP Business One creates an accounting journal entry without creating an inventory entry.

SAP Business One enables you to create an A/R reserve invoice with a zero amount. You can do this when delivering items without a charge, for example, items that are part of a promotion or covered by a service contract.

Like an ordinary invoice, a reserve invoice is closed against an incoming payment. However, inventory closure takes place in the delivery.
