WestRock challenges

Volume & complexity

Invoices from suppliers, purchase orders for materials, packing slips, and compliance certificates arrive in many formats. Some are scanned PDFs, others are system-generated. The variety makes automation difficult across both SAP S/4HANA and Coupa.

Supplier invoices, material orders, packing slips, and certificates arrive in many formats. The variety slows automation.

Manual load despite automation

Existing automation systems haven’t delivered. Teams still re-enter data line by line into SAP S/4HANA and Coupa. This slows turnaround, creates bottlenecks, and raises cost. Even small errors in quantities, prices, or delivery dates cause downstream rework.
