Supplier Frequently Asked Questions

Once you have registered and your information is verified, your profile will be available to all of our procurement professionals worldwide. Due to the volume of inquires we receive you will NOT be contacted until a purchasing professional matches one of our current needs with your offerings. 

US individuals and organizations complete the online registration, attaching a current IRS W-9 and a completed Supplier Registration Form. Organizations and individuals outside the US submit a completed Supplier Registration Form and current IRS form W-8BEN or W-8BEN-E to [email protected] prior to doing business with GW. Please visit the New Supplier Registration page for more information.

We ask that you ensure your data is correct and up-to-date. As this is a global database, it is important that your vendor profile is accurate so that projects and/or divisions within GW that may not be familiar with your company are presented with the best information.

The WCF determines whether an individual should be paid as an employee or as an independent contractor based on IRS guidelines. The department engaging the individual’s services is responsible for completing the form and submitting to the Tax Department for review prior to the individual being engaged and services performed. When approved, the form accompanies all other vendor registration documents. When not approved, the department should work with their Human Resource Representative to pay as an employee.

Existing suppliers should manage their organization’s banking and address information through the iSupplyGW portal. For additional assistance, call the iSupplyGW hotline at (571)553-0300 or email [email protected].

Due to the large volume of inquiries we receive, we do not provide direct phone numbers or email addresses of our purchasing organization. Instead, we use the Supplier Database as a means of routing information to one or more of our purchasing managers by product category. If you have a product or service you would like to introduce to GW, please register with us in the prospective Supplier Database and include any relevant brochures or attachments. When your registration is complete, your company information will be made available to all procurement professionals within GW.
