IDIQs & GWACs
12 min read
Indefinite Delivery/Indefinite Quantity (IDIQ) contracts and Governmentwide Acquisition Contracts (GWACs) are the backbone of federal procurement. Getting on the right contract vehicle can mean years of recurring revenue with lower competition.
What Is an IDIQ?
An IDIQ is a master contract that allows the government to order goods or services from pre-approved vendors over a period of time (usually 5–10 years) for an unspecified — but bounded — total value. Think of it as being on an approved vendor list.
Minimum Guarantee
The lowest the government must order — often just $1. Don't count on minimums.
Maximum Ceiling
The most the government can order total across all vendors. Often billions.
Task / Delivery Orders
Individual orders placed against the IDIQ. You compete for task orders, not the IDIQ itself.
Types of Contract Vehicles
One vendor holds the contract. Guaranteed revenue stream but harder to win. Common for agency-specific requirements.
Multiple vendors hold contracts. You then compete for task orders. Most common federal vehicle structure.
Government-wide — any federal agency can use it. Managed by a single agency (GSA, NASA, NIH). Highest visibility, hardest to get on.
A simplified ordering agreement, often established from GSA Schedule. Agency sets up a BPA with 1–5 schedule holders for their routine buys.
Similar to MATOC but used in specific sectors. DOD uses this term frequently for construction and services.

How to Get on a Contract Vehicle
- 1
Watch for Open Periods
Most IDIQs have limited on-ramp periods. GSA MAS is open continuously. Others open every 1–3 years. Monitor SAM.gov for solicitations.
- 2
Meet the Qualifications
Each vehicle has minimum requirements: years in business, past performance, financial statements, technical capabilities.
- 3
Write a Strong Technical Proposal
IDIQ proposals focus on capability, experience, and past performance — not price. This is where small businesses can compete on quality.
- 4
Price Reasonably
For GWACs and schedules, your rates are negotiated and published. Set competitive but sustainable rates.
- 5
Win Task Orders
Getting on the vehicle is the beginning. You still must respond to task order RFPs and win individual awards against other vehicle holders.
Pro Tip: Start with the GSA Multiple Award Schedule (MAS). It's the most accessible vehicle for new contractors and used by every federal agency. Once on schedule, agencies can place orders without a full competition.
