General Concept

The invoice feature within procurement is a simplification of a regular invoicing system and is not meant to replace proper invoices. Instead it shall be used as a way to inform customers (Consumers) about inbound invoices and their content. On top, because the Procurement platforms presents invoices in a well definite structure via API, it allows the consumer to analyse invoices and to optimize future orders.
