Case Study: GAF achieves automated PO and invoice processing and reduces rogue spend with SAP Ariba

GAF Automating POs and Invoices to Improve Compliance and Spend Management

GAF, North America’s largest commercial and residential roofing manufacturer with 23 plants and nearly $3 billion in annual sales, needed to modernize its procure-to-pay operations. Despite moving to an external invoice system, GAF had only an 8% touchless invoice processing rate, heavy buyer involvement, and significant rogue spend—limiting procurement’s ability to focus on strategic sourcing and to capture early-payment discounts.

GAF joined the Ariba Network and deployed Ariba PO Automation, Invoice Automation, and Procurement Content to expand catalogs and automate PO/invoice matching. In the first phase it enabled more than 975 suppliers, raised straight-through processing from 8% to 67% (100% for vending-machine catalog items), automated 60% of MRO transactions (covering 80% of Maximo spend), and significantly reduced rogue spend while enforcing contracted pricing and increasing supplier consolidation and discounts.
