Just-in-Time Delivery (Government)

Just-in-Time (JIT) delivery in government contracting is a supply chain management approach in which contractors deliver goods and materials to government facilities at or near the moment they are needed for use, rather than delivering large batches for storage in government warehouses. JIT arrangements reduce the government's inventory carrying costs, minimize storage requirements, and shift the burden of warehousing to the contractor or its supply chain. Federal agencies have adopted JIT principles across a range of commodity purchases, from medical supplies and office products to maintenance parts and food service items.

What is Just-in-Time delivery in government contracting?

JIT delivery in the federal context is implemented through contract terms that specify delivery windows, lead times, and demand signals. Delivery orders under indefinite-delivery contracts (FAR Part 16.5) are the most common mechanism: the government issues individual delivery orders as needs arise, specifying quantities and required delivery dates, and the contractor fulfills each order within the contractually stipulated lead time. The Defense Logistics Agency (DLA), which manages supply chain operations for all military services, extensively uses JIT principles in its prime vendor contracts for medical, food, construction, and industrial hardware commodities.

FAR Part 47 governs transportation and delivery terms in government contracts. Standard commercial delivery terms such as FOB Destination (FAR 52.247-34) establish when title and risk of loss transfer to the government, which is relevant to JIT arrangements because the contractor bears title and risk during transit. Contractors structuring JIT supply relationships must ensure that their own supplier agreements include corresponding lead time guarantees so that contractual delivery commitments to the government can be met without the contractor absorbing excess inventory.

DLA's prime vendor program for subsistence (food) is a widely cited federal JIT model. Under this program, a prime vendor contractor maintains relationships with food distributors and delivers to military dining facilities on a daily or every-other-day cycle based on menu requirements transmitted electronically. The government holds virtually no food inventory at installation level, relying entirely on the contractor's distribution network.

Why it matters for contractors

JIT contracts reward contractors with robust supply chain infrastructure and real-time inventory visibility systems. The government's demand signals - issued as electronic delivery orders or procurement system transactions - must be matched quickly with available stock or a confirmed supplier commitment. Contractors who cannot reliably meet stated lead times face cure notices, delivery deductions, and potential termination for default under FAR 49.4.

The risk profile of JIT contracts differs from traditional stocking contracts. Under a stocking model, the government absorbs the risk of demand variability through held inventory. Under JIT, demand variability risk shifts to the contractor. Contractors must price this risk into their bids, factoring in the cost of maintaining supplier relationships and buffer stock at their own facilities to protect against demand spikes or supply disruptions.

Supply chain risk management and business continuity planning are therefore essential for any contractor performing JIT delivery. Single-source supplier dependency is a common vulnerability that procurement auditors and agency program managers scrutinize in JIT arrangements.

Example

A DLA prime vendor contractor for industrial hardware delivers fasteners, gaskets, and other consumable maintenance parts to a Navy shipyard. The shipyard submits electronic requisitions each morning, and the contractor delivers to designated receiving docks within four hours for routine items and two hours for priority items flagged as mission-critical. The contractor maintains a regional distribution center near the shipyard stocked with the top 500 highest-velocity items to guarantee fill rates above 98 percent without carrying excess inventory at the government facility.
