Case Study: Vestas achieves unified procurement, better supplier collaboration, and 75% faster invoice handling with SAP Ariba solutions

Vestas Scaling Quality, Sustainability, and Efficient Supplier Collaboration with Digital Procurement

Vestas, a global leader in wind turbine solutions, faced fragmented, manual procurement as it expanded into new onshore and offshore markets and scaled a supplier network that manages about half of its manufacturing. The company needed a single, user-friendly platform to standardize supplier onboarding, ensure sustainability and compliance across suppliers, and accelerate product cycles while reducing administrative overhead.

Vestas implemented SAP Ariba solutions (with SAP Signature Management by DocuSign) integrated with its SAP ERP to create a unified source-to-pay platform, enable guided buying, e-auctions, automated PO/invoice matching, and digital contract management. The rollout onboarded thousands of suppliers and ~2,000 users, delivering one place for supplier and procurement data, a 75% reduction in parked/blocked invoice handling time (7x fewer such invoices), measurable cost savings (including 7% from e-auctions) and an estimated >€20 million in savings over five years, while improving compliance, traceability, and time-to-market.
