The Vendor Support Center (VSC) is the online source for vendors to obtain information, review and report sales, and more. The VSC website contains a wealth of information to assist both GSA Schedule and Governmentwide Acquisition Contract (GWAC) contractors in fulfilling the contract administration requirements of their respective contracts. Online information is available 24 hours a day, 7 days a week.

The VSC also contains information regarding the Multiple Award Schedule (MAS) Express Program, a specialized program designed to simplify, streamline, and ultimately accelerate the process for vendors to obtain GSA Schedule contracts.

The VSC maintains a staff ready to assist vendors in the preparation and submission of electronic catalog files to GSA Advantage!®, and in the submission and reporting of sales data. Vendors may contact the VSC staff Monday - Friday, 7:30 a.m. - 5:30 p.m. Eastern Time, on (877) 495-4849, or via email at vendor.support@gsa.gov.
