Understanding GSA Order Types: Delivery Orders vs. Task Orders

GSA Order Types: Delivery Orders vs. Task Orders

GSA Schedule contracts are indefinite delivery vehicles — they establish pricing and terms but do not guarantee any work volume. Actual purchases happen through individual orders placed against your Schedule contract. Understanding the two order types — delivery orders and task orders — clarifies your contractual obligations and helps you structure your proposal responses correctly.

Delivery Orders (Products)

A delivery order is issued for the purchase of products (supplies) from your Schedule contract. The delivery order specifies the item(s), quantities, delivery location, and delivery date. Payment is typically tied to successful delivery and acceptance. Delivery orders are used when the government needs physical goods — IT hardware, office supplies, lab equipment, or other tangible items listed on your Schedule pricelist. The ordering agency places a delivery order using your Schedule contract number and the specific SIN covering the items.

Task Orders (Services)

A task order is issued for services under your Schedule contract. The task order defines the scope of work, performance period, deliverables, place of performance, and ordering agency requirements. Services under GSA Schedules are often ordered as Labor Hour (LH) or Time-and-Materials (T&M) task orders, though Firm Fixed Price (FFP) task orders for defined deliverables are also common. Task orders may include a base period with option periods, which the ordering agency can exercise to extend performance without issuing a new competition.

Fair Opportunity for Orders Over $25,000

For orders expected to exceed $25,000, the ordering agency must provide all Schedule contractors offering the relevant SIN a fair opportunity to be considered. This is distinct from a full and open competition — it is a simplified competitive process conducted within the Schedule vehicle. For orders exceeding $10 million, additional requirements apply, including a requirement for the agency to document why the ordering contracting officer did not follow the procedures for a competitive task or delivery order. Orders under $25,000 (the simplified acquisition threshold exception) can be placed without a competition.

Order-Level Materials (OLMs)

Order-Level Materials are supplies and/or services acquired in direct support of a task order, not separately priced on the Schedule contract. OLMs allow the ordering agency to include needed ancillary items in a task order without requiring a separate procurement. OLMs are subject to a limitation: they cannot exceed 33.33% of the total task order value. Understanding OLMs is important for professional services contractors who are often asked to procure materials alongside labor.
