Find Success as an IPG Supplier

Registering as a Supplier

IPG’s supplier management program requires non-media suppliers to register via the SAP Ariba Network. The SAP Ariba Network offers increased information security and efficiency in the supplier onboarding process by allowing suppliers to self-register and directly maintain their data whether a supplier is a new partner or an existing partner that needs to update their supplier information. The below instructions are only applicable to suppliers supporting IPG’s agencies in the U.S.

IPG media suppliers supporting agencies in the U.S. and all suppliers supporting IPG agencies outside of the U.S. will continue to follow the legacy onboarding and maintenance processes.

Supplier Onboarding

What To Expect

All non-media suppliers supporting IPG’s United States agency operations should expect to receive a system generated email invitation to begin the registration process with IPG via the SAP Ariba Network. This email will include the following attributes:

From: ‘IPG Corporate’ with a domain including

Subject: Invitation: Register to become a supplier with [followed by specific IPG agency name, etc.]

A daily automated reminder email is sent after this initial invitation to register. If you are not able to locate this email, please check your spam or other email folders, or contact your local IT support desk to adjust your email settings for restricted domains. Suppliers will have 9 business days to complete the form after the initial invitation is received.

If you have previously done business with the Interpublic Group of Companies or its subsidiaries, you should have received an email prior to the invitation with instructions for validating and updating the information we currently have on file.

In preparation for receiving an invitation, please collect the following documents:

  • Bank support: A copy of your bank statement with full account holder name and number, voided check, OR, deposit slip; please note that bank letters are not acceptable
  • Tax document: W9, if a non-US supplier your W8 form is available via the Comply process outlined below. Tax documents must be signed and dated within the last two years.
  • Support for any third-party management arrangements, if applicable
  • Diversity certificates, if applicable
