The supplier knowledge you need, all in one place.
The Coupa solution provides many benefits to our suppliers, including free access to the Coupa Supplier Portal (CSP) where customers can manage their company information, view their POs, invoices, payment status and initiate e-invoicing to eliminate paper and support WM's green initiatives.
Contact the WM Corporate Accounts Payable team at wmsc.ap@wm.com and request to have your Coupa invoice disputed. Once the invoice shows in disputed status, you can submit a correction or void the invoice. Disputed invoices will be voided after 90 days of inactivity.
