What Is the GSA Vendor Support Center and How to Use It
The GSA Vendor Support Center (VSC) at vsc.gsa.gov is a free support resource for GSA Schedule contractors and applicants. It provides how-to guides, FAQs, webinars, pre-submission review, and a help desk for addressing questions about the Schedule program. The VSC is one of the most underutilized resources available to contractors — most applicants are unaware that free pre-submission review can catch deficiencies before they reach a CO's desk.
Key VSC Resources
The VSC maintains an extensive library of resources: how-to guides for eOffer and eMod workflows, recorded training webinars on pricing, compliance, and application preparation, FAQs organized by topic (pricing, modifications, reporting, etc.), and the VSC help desk that answers specific questions about solicitation requirements. The help desk can be reached by email or phone and typically responds within 1–2 business days. For complex questions about specific SIN requirements, the help desk can often tell you whether your approach to a section will satisfy the CO's review criteria.
The Pre-Submission Review Service
The most valuable VSC service is the free pre-submission review. Submit your draft offer to the VSC before submitting in eOffer, and VSC staff will identify obvious deficiencies, missing documents, or issues with your pricing structure. This review does not guarantee CO approval — it is not a formal review — but it catches the most common errors that generate deficiency letters. Schedule the VSC review at least two weeks before your intended submission date to allow time to incorporate feedback.
