Supplier FAQs
The supplier knowledge you need, all in one place.
Coupa at WM
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.
WM is committed to paperless processing as part of our Green initiatives. We hope that all our Suppliers will partner with us by signing up for a Coupa account to transact electronically.
To begin this process, Contact Supplier Support at [email protected]. Please include your company name and contact information so that we can reach out to you.
Coupa doesn't charge suppliers to use the CSP.
Suppliers that need registration help can use the Coupa Success Portal or download the Suppliers Guide for Registration and E-Invoicing.
If you have a CSP account, go to your Customer Profile and select WM as the customer. Complete the WM SIM form with the info needing to be updated, then click Submit. Otherwise, reach out to your local WM contact.
WM will not issue payments through Coupa. However, you will be able to see your payment details through the Coupa Supplier Portal.
If you do not have a Coupa Supplier Portal Account, WM offers an Invoice Portal where you can see your payment status.
If you have confirmed that payment has been issued on our Coupa Supplier Portal or through the Invoice Portal but you did not receive it, please reach out to us at [email protected].
Invoicing
Contact the WM Corporate Accounts Payable team at [email protected] 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.
For any purchase order issues, email the WM Corporate Accounts Payable team at [email protected].
To add additional funds or to inquire about a change order, contact the requestor. Their contact information will be available on the purchase order you received.
Regardless of the method used to submit invoices, please ensure you clearly denote the WM PO # and PO Requester on the invoice.
