Small purchases that never start
The cardholder's rulebook is layered: the FAR, the DFARS, a department guidebook, Navy and Army supplements, local procedures and the cardholder's own written appointment. The most restrictive one decides, and few vendors or customers know where it sits for a given buy.
The costliest misunderstanding involves labor. A buyer who reads every service as covered by the Service Contract Labor Standards applies a $2,500 ceiling to professional work that can qualify for $15,000. The government makes that call, and a vendor's description of its offering shapes how easily it gets made correctly.
What the paper answers
- Which micro-purchase limit applies to products, covered services, construction and contingency buys?
- When does a study, assessment or workshop fall outside the Service Contract Labor Standards?
- What can a card do above the micro-purchase threshold, and which designation does a Navy cardholder need for it?
- Which purchases do the department, the Navy and the Army prohibit or restrict, and where do the lists differ?
- Why do third-party payment processors, surcharges and click-through licenses stall a card sale?
- What does a card payment change about the Prompt Payment Act and assignment of claims?
A look inside
One of three tables in the paper. The micro-purchase threshold depends on what is being bought.
| What is being bought | Limit per purchase | Why |
|---|---|---|
| Products, and services not covered by the service-contract wage law | $15,000 | The general micro-purchase threshold |
| Services covered by the Service Contract Labor Standards | $2,500 | The wage law applies above this amount, which requires a contract with wage clauses |
| Construction covered by the prevailing-wage law | $2,000 | The prevailing-wage law applies above this amount |
| Contingency operations, certain defense against attack, and disaster response | $25,000 inside the United States; $40,000 outside | Higher thresholds set by regulation |
| Commercial purchases made overseas for use overseas | Up to $25,000 | Specially appointed and trained buyers only |
