The accounts payable department is a necessity for most enterprises – generally viewed as an operational cost – and therefore needs to be run as economically as possible. In an ideal world, the department would generate a high volume of invoices processed per person with short invoice posting times and have checks and balances to ensure high data quality.
Even with SAP ERP, the process of supplier invoice payment can be expensive, with many tasks requiring a lot of manual effort. Invoice posting is usually time-consuming. Process inefficiencies are often identified by intuition rather than with real supporting evidence.
