WOSB or EDWOSB: the one most people get backwards

EDWOSB sounds like the smaller certification. It reaches more contracts, not fewer.

Almost every guide online describes EDWOSB as a narrower, harder version of WOSB. That is backwards, and believing it can cost you contracts you were entitled to bid.

What the two actually reach

SBA studies which industries women are underrepresented in, and publishes the result as a list of NAICS codes split into two groups. There are 733 designated industries in total.

Every EDWOSB is also a WOSB. So an EDWOSB certification reaches all 733 designated industries. A plain WOSB certification reaches 626 of them and cannot touch the other 107.

Janitorial services is one of the 107, and so are several other high-volume service industries. Certify WOSB alone and you will watch contracts you cannot bid on go past.

Who qualifies as economically disadvantaged

All three of these must be true of the qualifying owner, and they are separate tests that get conflated constantly.

The net worth cap of $850,000 is the tight one, and it is a different number from the $6.5 million asset test. Plenty of sites quote the asset figure as if it were the net worth limit. It is not. Net worth calculations for this purpose also exclude your primary residence and your ownership stake in the business itself, which is why more applicants clear it than expect to.

What to do about it

Check whether your NAICS code sits in the 626 or the 107. If it is in the 107, EDWOSB is the only certification that reaches your industry and there is no decision to make. If it is in the 626 and you meet the economic thresholds, apply for EDWOSB anyway: it costs the same, takes the same time, and covers strictly more ground.
