Saving by using an e-Invoicing system to manage supplier invoices:
100% scanned invoices with workflow => 5,41$ / invoice.
Over time the % of electronic invoices increase to 40% => 4,39$ / invoice.
The OCR invoices increases but in the longer term supplier move to e-invoicing ( via cXML, EDI...) up to 75%. => 3,10$ / invoice
