After the SAP Ariba invoicing solution receives an invoice from SAP Business Network, or a user manually creates an invoice in the SAP Ariba invoicing application, the next step is to reconcile the data on the invoice with the matching purchase order, receipt, or contract data to make sure the invoice is correct. The matching of the related documents can be done automatically by the system, or, if that is not possible, by an exception handler. The system allows for setting up different levels of matching.
Customers have the option to choose between a 2-way or 3-way invoice match. This choice determines whether it is sufficient to match the invoice with the corresponding order (2-way match), or if an additional record, such as a goods receipt or an approved service entry sheet, is necessary (3-way match).
Many companies prefer a 3-way match to gain an adequate understanding of their spending. Others adopt a 2-way match to simplify the process for low value purchases. For example, a 2-way match might be sufficient for low value purchases, such as office supplies. However, if the invoice is for a core purchase, for example, IT items, a 3-way match is recommended.
