Answer 1

To get assistance setting up Microsoft Advertising and to work with an Account Manager for supplier/billing-related setup, use the Microsoft Advertising Customer Support channels and your Xandr/Microsoft Advertising representatives.

If there is already a Microsoft Advertising/Xandr relationship:
- Reach out directly to the existing Microsoft Advertising (Xandr) Account Representative for any business-related inquiries, including billing, onboarding, and supplier setup. Business-related topics are explicitly handled by the Account Representative rather than technical support.
If there is no known Account Manager or the contact is unclear:
- Go to the Microsoft Advertising Customer Support Portal: https://support.ads.microsoft.com.
- Open the Customer support contact form ("Contact Support").
- Submit a request describing that the organization needs to set up “Microsoft Online Inc” as a supplier and requires connection with an appropriate Microsoft Advertising Account Manager or Business Support team.
- In the request, include:
  - Company details and billing/supplier requirements.
  - Any existing Microsoft Advertising Member ID or account identifiers (if available).
  - A clear statement that the request is business-related (supplier setup, billing, payments) so it can be routed to Business Support/Account Management.
For billing-address or finance-related changes once a relationship exists:
- Use the Microsoft Advertising Customer Support Portal and select Contact Support to reach the Client Finance team for billing and remittance questions.

For ongoing business topics such as billing, training, and general commercial setup, communication is expected to go through the Microsoft Advertising Account Representative or Business Support rather than the technical support queue.

Answer 2

Hi Lizanne,

Thank you for using our Microsoft Advertising Learn Q&A Platform!

I understand the urgency around setting up Microsoft Online, Inc. as a supplier for Microsoft Advertising.

To support your request, Microsoft Advertising can provide official supplier/vendor documentation that is typically required for onboarding Microsoft as a vendor in your procurement or accounts payable system. These documents include standard vendor forms, tax forms (such as W‑9 where applicable), and banking details.

Please note that Microsoft generally does not complete or sign third-party supplier forms or questionnaires. Instead, we provide our own standardized documentation, which is designed to meet most supplier setup and compliance requirements. Additionally, Microsoft adheres to its own published corporate policies, including the Microsoft Standards of Business Conduct and Privacy Statement, which may support your internal review process.

I hope the information provided here will at least partly answer your question. If you have any additional questions, please do not hesitate to reach out to our support. I have also sent you a private message asking for further details. You are more than welcome to respond to me so that I can begin the investigation on my end.

Kind regards,

Arsen D. | Microsoft Advertising Support Specialist | 800-518-5689
