An A/R reserve invoice is a special form of A/R invoice that provides revenue recognition (and payment) prior to the delivery of goods or services.

The initial advance calculation is used in cases in which a Pro forma invoice is required for special declarations (e.g. customs). Only the necessary accounting transactions are created, while the inventory postings are made at a later date.
This is the case if the goods have been delivered and a delivery has been created in SAP Business One on the basis of the A/R reserve invoice. It is also possible to create an A/R reserve invoice with a zero amount.
This method can be used to article that were intended to be delivered free of charge, e.g. those that are part of a promotion or are subject to a Service contract fall.
