Three tiers, not one set of rules
Every federal purchase falls into one of a few tiers based on dollar value, and the tier decides which procedures the agency has to follow. This matters before you read a single notice, because the tier tells you how heavy the competition and the paperwork are likely to be.
Micro-purchases, card swipe territory
At the bottom sits the micro-purchase threshold, a purchase small enough that a government employee can often buy it directly, commonly with a government purchase card, without running a formal competition. As of 2026 this threshold sits in the low thousands of dollars. Below it, there is often no posted notice at all. This is the easiest tier to sell into and the hardest to find, because so little of it is advertised anywhere you would normally look.
Simplified acquisition, lighter but not casual
Above the micro-purchase line sits simplified acquisition. As of 2026, this covers purchases up to somewhere in the low hundreds of thousands of dollars. The procedures here are genuinely lighter than a full negotiated procurement, built deliberately to be friendlier to small businesses: fewer formal proposal requirements, faster timelines, and rules that favor small business competition by default when a purchase falls in this range. If you want a realistic first win, this tier is usually a better hunting ground than the eight-figure program everyone already knows about.
Above both, the full machinery
Once a purchase is priced above the simplified acquisition threshold, it falls under the full negotiated procurement rules: formal evaluation factors, a source selection process, often a longer solicitation with many more sections to satisfy. Nothing about this tier is impossible for a small business, but it asks more of you, a fuller proposal, more compliance detail, sometimes past performance you have not built yet.
The numbers move, so verify before you rely on them
The thresholds themselves are not permanent. They get adjusted periodically, sometimes tied to inflation, which is exactly why this page gives ranges instead of figures you might mistake for fixed. Before you rely on an exact number for a real decision, such as whether a purchase you are chasing needs a full proposal or just a quick quote, check the current figures on acquisition.gov, where the FAR itself is published.
Why you should check the tier before anything else
The tier tells you what kind of competition you are walking into before you read a word of the requirement itself. A simplified acquisition set-aside is a different fight than an eight-figure negotiated award that happens to also be set aside. Same label, different weight class. The full negotiated tier also tends to draw larger, more practiced competitors with dedicated proposal teams, while the lower tiers draw a thinner, more approachable field, which is part of why they are worth learning first. Get in the habit of noticing which tier a notice sits in as the first thing you check, not the last.
