Two jobs, one check
The compliance answer is also a credit answer.
Banks, credit unions and non-bank lenders alike carry Bank Secrecy Act obligations: a Customer Identification Program, customer due diligence, beneficial ownership at 25% or control, and ongoing monitoring across the life of the loan. Non-bank lenders often have lighter direct obligations and then inherit equivalent ones by contract, from funding sources, warehouse lenders or loan purchasers.
What is easy to miss is that the same file answers a second question. Whether a business is in good standing is eligibility; whether it is actually operating is underwriting. Years in business is a track record. Ownership stability is management continuity. The check is paid for once and can be read twice.

Why it is hard
The largest lending market is the least documented one.
33 million U.S. businesses have fewer than 500 employees, and 27 million of those are non-employer businesses — solo operators. Many sole proprietors have no formal registration at all. There are no audited financials, no public filings, and often almost no online presence.
Traditional KYB was built for larger companies: check the Secretary of State record, verify the corporate officers, trace institutional ownership. None of that reaches a plumber operating as a sole proprietor under a DBA. The method is not weak, it is aimed somewhere else.
03
The framework
Four tiers, and most applications stop at the first.
Tier 1 is instant and decides basic eligibility in the application flow: the legal entity exists and is active, the name matches or resolves, a registered agent and address are on file, no sanctions hit on the business or its principals, the business type is inside policy. Failures stop here; passes continue.
Tier 2 confirms beneficial ownership and verifies principal identities. Tier 3 is the one lenders under-build: operating verification — evidence that the business is trading now, rather than merely registered. Tier 4 is enhanced due diligence, and it should be triggered rather than routine.
The discipline is in the ordering. Every tier costs more than the one before it, so anything that can decline at Tier 1 must decline at Tier 1, and anything that can approve on operating evidence should never reach Tier 4.

Segments
The same policy meets three different difficulties.
An established business with years of history, a formal structure and documentation is the easy case, and standard KYB works on it. A newly formed entity has a thin file by definition — the absence of history is not evidence of anything, and treating it as such declines real businesses.
Sole proprietors are the hard case, because they lack most of the anchors the process is built on. There is no incorporation record to check. What exists instead is operating evidence: a licence, a DBA registration, an address that resolves, transactions that happened. A programme that can only verify corporations will decline a large share of the market it is trying to serve.

What it costs to get wrong
Both errors are expensive, in opposite directions.
Verify too little and the loss is fraud and a regulatory finding. Verify too much and the loss is quieter but larger: borrowers abandon slow applications, and the ones with the most options abandon them first. A KYB programme that takes three days to clear a real business is a credit policy, whether or not anyone wrote it down as one.
