If you reasonably believe the awardee of a small business set-aside is really a large business, then you can file a Small Business Administration (“SBA”) size protest. The federal government reserves a portion of its procurement dollars for purchasing products or services from small businesses. These set-asides help small businesses compete for federal government contracts. Not surprisingly, however, some businesses who are initially awarded these contracts are actually large businesses posing as small business concerns. A size protest presents a quick and economical option to challenge the award to such a large business.
