What's the difference between a small business set-aside and an 8(a) sole source award?

A general small business set-aside is open to all eligible small businesses, while an 8(a) sole source award is specifically designated for a single firm participating in the SBA's 8(a) Business Development Program. For a general small business set-aside, the contracting officer expects offers from at least two responsible small business concerns at fair market prices, which is known as the Rule of Two (FAR 19.502-2(b)). Your 8(a) firm would compete against all other small businesses. For an 8(a) sole source award, the government can directly award a contract to your firm without full competition, if the anticipated value does not exceed $5.5 million for most acquisitions or $8.5 million for manufacturing NAICS codes (FAR 19.805-1(a)). This direct award process typically offers a higher chance of winning for an 8(a) firm because it limits the competition to a single firm. However, such opportunities are at the discretion of the contracting officer and the SBA.
