Frequently asked questions about contract vehicles
A contract vehicle is a pre-negotiated, government-wide agreement that allows agencies to purchase products and services without running a full competitive acquisition each time. The most common types are Multiple Award Schedules (GSA MAS), Government-Wide Acquisition Contracts (GWACs), and Blanket Purchase Agreements (BPAs).
The GSA Multiple Award Schedule (MAS) is the broadest vehicle covering thousands of categories, open to businesses of all sizes. GWACs (like SEWP, OASIS+, STARS III) are more specialized — typically focused on a specific domain like IT or professional services — and usually offer higher ceiling values and longer terms. GWACs often require stronger past performance than GSA MAS.
GSA Schedule applications typically take 6–12 months from submission to award. Responsive, complete applications are processed faster. A GSA Schedule consultant can reduce rejection risk but adds cost. The schedule is valid for 20 years with annual modifications.
Yes — and most successful government contractors hold multiple vehicles. GSA MAS is typically the foundation; GWACs like SEWP or OASIS+ add access to specific agency programs. Having multiple vehicles increases the number of agencies that can buy from you without running a full competition.
Many GWACs are closed (no new applicants) for most of their contract period. Open seasons are limited windows when new companies can apply for a spot on the vehicle. Missing an open season can mean waiting years for the next one. Monitor SAM.gov and GSA websites to catch them.
OASIS+ is the successor to the original OASIS contract, launched in 2024. It covers complex professional, management, and technical services with separate pools for unrestricted, small business, 8(a), WOSB, HUBZone, and SDVOSB firms. OASIS+ replaces both the original OASIS and its small business companion.
