A BPA is a simplified ordering arrangement under FAR Part 13, designed for repetitive, low-dollar acquisitions where issuing individual contracts for each purchase would be inefficient. The BPA establishes terms — pricing, ordering procedures, authorized users, and a maximum dollar threshold per call — that govern subsequent purchases (called BPA calls). BPAs are most commonly issued against existing GSA Schedule contracts but can also be standalone agreements outside of Schedule.
A BPA itself is not a contract — it is an agreement that creates the conditions under which contracts (BPA calls) will be issued. Multiple awardees can hold BPAs against the same scope, and the agency can compete BPA calls among the holders for orders above a competition threshold. Below that threshold, calls can be issued directly to a single BPA holder. BPAs typically have a maximum order value and an aggregate dollar cap; once the cap is reached, the BPA must be re-established or extended through modification.
For small contractors, a BPA against an active customer is a low-friction sales channel. The procurement lead time for BPA calls is dramatically shorter than for new contracts — sometimes hours rather than months — and the customer relationship is built into the structure. The strategic question is whether the BPA's expected order volume and pricing structure justify the time invested in negotiating it. For frequently-buying customers, BPAs are extremely high-leverage; for sporadic buyers, they are administrative overhead.
