SAP Convergent Invoicing has four main agreements that you must be aware of. They are Master Agreements, Invoice Agreements, Invoice List Agreement, and Discount Agreement. This lesson defines these agreements, going into more detail on discount agreements at the end, as it is more complex.
Master Agreement
A master agreement is a contract between a provider and another party (usually a large company) in which common terms for future contracts are defined. The common terms can cover aspects of invoice creation (layout, recipient, payer, and so on) as well as discounting (which services have a reduced price and who benefits).
The master agreement in SAP S/4HANA concentrates on the processing/billing side of provider contracts which reference a master agreement. Billable items which belong to such a provider contract have to be treated as specified and agreed upon in the master agreement. For instance, for which invoice and which discount(s) should the billable item be considered.
The reason for having a master agreement in place is for the customer to benefit from the common terms. With them, a consolidated and harmonized processing of billable items is possible. One business partner can have multiple master agreements.
