How Do I Know If a Business Buyer Is Serious? Proof of Funds and the Other Tells

The fastest tell: a serious buyer proves they can pay before they ask to see your books, and a tourist is offended you asked. Everything else — the probing questions, the lender pre-qualification, the steady response cadence — follows from that first exchange. The stakes of getting this right are not small: only 20–30% of listed businesses ever sell, and every month spent entertaining a fantasy buyer is a month your real buyer is signing someone else's LOI.

Proof of funds: the price of admission

Proof of funds means recent bank or brokerage statements showing liquid cash for the down payment, or a pre-qualification letter from a named lender. It's requested after the NDA, before detailed financials — that ordering is industry standard, and a buyer who's bought anything before expects it. What doesn't count: screenshots, "my investor group is finalizing commitments," wealth that's all home equity, or net-worth statements with nothing liquid in them.

Note what you're testing: not whether the buyer is rich, but whether their cash matches their appetite. With about 78% of buyers using SBA financing, a buyer pursuing your $600,000 business needs roughly 10% down plus working capital — call it $80,000–$100,000 liquid. A buyer with $30,000 isn't dishonest, just shopping two sizes up. It happens to be the same screening a confidential sale needs anyway: the fewer unqualified eyes on your financials, the fewer leaks.

The math a serious buyer has already run

Real buyers arrive having done the lender's arithmetic, because they know the bank — not the seller — approves the deal. You can run it from your side in five minutes, and you should, for every offer you're weighing.

Behavioral tells: cadence beats charm

Serious buyers move on a rhythm. They answer within a day or two, ask for specific documents by name — three years of P&Ls, the lease, revenue by customer — and their questions get narrower each round, converging on a decision. They talk about their timeline unprompted ("I want to be under LOI by March") and they've engaged an accountant or attorney you can verify exists.

Tourists drift. Weeks between emails, questions that stay big and dreamy ("what's the growth potential?"), a fourth site visit with no offer in sight, and financing plans that reorganize themselves each time you ask. The polite-but-firm move: after the second meeting, ask directly — "What do you need to make an offer, and when will you make one?" Serious buyers answer with a list and a date. Tourists answer with a feeling.

A special mention for the buyer who wants you to finance nearly the whole price. Seller notes are normal — 90% of buyers expect some — but "10% down from me, 90% carried by you" isn't a purchase, it's a lease with your name on the risk. Our seller financing guide covers where the sane boundaries sit.

What disciplined screening looks like

This is a large part of what a good broker's fee buys. The sequence: inquiry → NDA plus buyer profile → proof of funds → then, and only then, the CIM with your identity and numbers. Ask a broker you're interviewing what fraction of inquirers ever see the full package; a disciplined answer is a small number said without apology. Ask how they pre-qualify deals with SBA lenders before buyers even appear — the best ones have the loan half-built before the right buyer walks in. (It's also a fine interview question for separating dealmakers from listing mills.)

And when a genuinely serious buyer does show up — proof of funds, crisp cadence, numbers that work — move. Qualified buyers are the scarce side of this market. The discipline isn't just about rejecting tourists; it's about recognizing the real one fast enough to close before the calendar does its damage.

Frequently asked questions

What is proof of funds when selling a business?

Bank or brokerage statements showing liquid cash for the down payment, or a named lender's pre-qualification letter — provided after the NDA, before detailed financials. Screenshots and unnamed investors don't count.

How do brokers screen out unqualified buyers?

NDA, buyer profile, and proof of funds before identity and financials are released, then a check that cash, timeline, and target size match reality. A small share of inquirers seeing the full package means the filter is working.

What are the red flags of an unserious buyer?

Refusing proof of funds, vague financing, no questions with numbers in them, weeks of silence, near-total seller financing requests, and repeat visits with no offer. Serious buyers produce a list and a date when asked what they need.
