FAR 13.203—Purchase guidelines.
Plain-English Summary
FAR 13.203 sets the basic purchase guidelines for micro-purchases under simplified acquisition procedures. It addresses four main topics: equitable distribution of micro-purchases among qualified suppliers, when a contracting officer or authorized purchaser may award a micro-purchase without soliciting competitive quotations, when and why price reasonableness must be verified, and what documentation is needed when competitive quotations were obtained but award is made to someone other than the low quoter. The section is designed to keep micro-purchase buying fast and low-burden while still protecting the Government from unreasonable prices and arbitrary purchasing decisions. In practice, it gives contracting officers and authorized buyers flexibility to use common-sense judgment instead of full competition for very small buys, but it also requires enough oversight to avoid favoritism, poor value, or unsupported award decisions. It is especially important because micro-purchases are frequent, time-sensitive, and often made with minimal paperwork, so this rule balances efficiency with basic accountability.
Key Rules
Equitable distribution
To the extent practicable, micro-purchases must be distributed equitably among qualified suppliers. This means agencies should avoid repeatedly favoring the same vendor when other qualified sources are available, but the requirement is flexible and tied to practicality.
No quotes required if price is reasonable
A micro-purchase may be awarded without soliciting competitive quotations if the contracting officer or authorized individual determines the price is reasonable. The rule allows quick awards based on judgment rather than mandatory competition.
Verify price only when needed
The Government does not need to routinely verify price reasonableness for every micro-purchase because the administrative burden may outweigh the savings. Verification is required only when there is reason to suspect the price is unreasonable or when no comparable pricing information is readily available.
Triggers for price review
Price reasonableness should be checked when the buyer has a suspicion or information suggesting the price may be too high, such as a comparison to a prior price paid or personal knowledge of the item or service. It is also required when buying something that is not comparable to recently purchased competitive items or services.
Limited documentation for non-low award
If competitive quotations were solicited and award is made to other than the low quoter, the documentation may be limited to identifying the firms solicited and explaining why the selected offer was chosen. The rule keeps paperwork light while still requiring a basic record of the decision.
Responsibilities
Contracting Officer
Ensure micro-purchases are distributed equitably among qualified suppliers to the extent practicable, determine whether a quoted or unquoted micro-purchase price is reasonable, decide when price verification is necessary, and document the basis for award when competitive quotations were received but the low quoter was not selected.
Individual appointed under FAR 1.603-3(b)
When authorized to make purchases, apply the same judgment as the contracting officer in determining price reasonableness, deciding whether verification is needed, and making or supporting award decisions consistent with micro-purchase rules.
Agency/Buying Activity
Establish and oversee micro-purchase practices that support equitable supplier distribution, reasonable-price determinations, and minimal but sufficient documentation. The agency should ensure personnel making micro-purchases understand when competition, price checks, and records are required.
Qualified Suppliers
Compete for micro-purchase opportunities when solicited and provide pricing and other information needed for the buyer to assess reasonableness and make an award decision.
Practical Implications
Micro-purchases are meant to be fast, so buyers do not need to run a full competitive process every time, but they still need a defensible basis for believing the price is fair.
A common mistake is treating micro-purchases as having no oversight at all; FAR 13.203 still expects reasonable judgment and, in some cases, price verification.
Another pitfall is repeatedly buying from the same vendor without considering whether distribution among qualified suppliers is practicable, which can create appearance-of-favoritism concerns.
If quotes are solicited and the award goes to someone other than the lowest-priced offer, the file should still show who was asked and why the selected supplier was chosen; otherwise the award decision may look unsupported.
When no comparable pricing information exists, buyers should be more cautious and gather enough information to support reasonableness, since the rule specifically calls for verification in that situation.
Official Regulatory Text
(a) Solicitation, evaluation of quotations, and award. (1) To the extent practicable, micro-purchases shall be distributed equitably among qualified suppliers. (2) Micro-purchases may be awarded without soliciting competitive quotations if the contracting officer or individual appointed in accordance with 1.603-3 (b) considers the price to be reasonable. (3) The administrative cost of verifying the reasonableness of the price for purchases may more than offset potential savings from detecting instances of overpricing. Therefore, action to verify price reasonableness need only be taken if- (i) The contracting officer or individual appointed in accordance with 1.603-3 (b) suspects or has information to indicate that the price may not be reasonable ( e.g., comparison to the previous price paid or personal knowledge of the supply or service); or (ii) Purchasing a supply or service for which no comparable pricing information is readily available ( e.g., a supply or service that is not the same as, or is not similar to, other supplies or services that have recently been purchased on a competitive basis). (b) Documentation. If competitive quotations were solicited and award was made to other than the low quoter, documentation to support the purchase may be limited to identification of the solicited concerns and an explanation for the award decision.
