Micro purchases are smaller government buys — roughly $100,000 and below for most agencies, around $200,000 with the Department of Defense — that follow a dramatically simplified process. The agency does not have to collect multiple bids, so awards work close to first-come, first-served, and the submission can be as simple as a one-page quote with your price, quantity, and delivery date.
They matter for newer contractors for several reasons:
The paperwork is minimal, often with no capability statement requirement, so you can respond yourself without mentor representation.
Because many contractors overlook them, they are low-hanging fruit that pops up daily at every level of government.
They are a practical way to start transacting with agencies and building past performance, which then supports bidding on larger contracts.
Being registered and visible in the government's vendor systems is what makes these purchases come to you — agency employees simply contact registered vendors directly. Above the micro purchase threshold, contracting officers must collect multiple bids and formally justify the winner, which is where heavier proposals begin.
