A business for sale is legitimate when three things hold up. The seller is who they claim, and owns the store and the company behind it. The order ledger shows a real operating history, not just a claim. And the seller accepts escrow, not a direct wire. A listing's story or a screenshot proves none of that on its own.

Does the Entity Actually Exist
Identity gets checked before revenue does because fraud is what actually kills a marketplace, not a bad multiple, so ownership is the first door, not the last. Ask the seller directly who legally owns the company - a name, not a brand - and check it matches the login and the bank account the money would move to. Ask whether there are co-owners or investors the listing never mentioned. A vague or shifting answer to either question is the answer: an entity that will not confirm who owns it is not one to wire money toward yet. That costs nothing but a conversation, and it works on any marketplace. Kairos's paid, human-reviewed tier runs this same check by hand - an ID on the seller, ownership confirmed against records, a look for undisclosed co-owners. The free automated tier does not: it reads a store's order data, never who is behind it. A free or automatic revenue check is not an identity check, here or anywhere else, so ask the ownership questions yourself regardless of what a badge says.
Does the Business Have a Real Operating History
A real business leaves an order ledger; a fabricated one leaves a story. Ask for the order-level export, not a revenue summary the seller typed up, and set the total against whatever revenue was claimed yourself - a spreadsheet can say anything, an order ledger takes months to fake convincingly. On Kairos this comparison runs as a published check: the gap warns past 10% and fails past 20%, because a real business's own bookkeeping does not drift from its own story by more than that. Run the same math on any listing, on any marketplace: months of orders that reconcile against a claim are a different animal from a growth story with nothing behind it. This is an existence check, not a benchmark - it tells you the business is real and operating, not whether its numbers are good ones.
Does the Money Move the Right Way
Escrow resistance is a tell because of what it costs a legitimate seller to accept it: nothing. If the business, the assets, and the ownership are real, waiting on a confirmed transfer costs a genuine seller a few days, not the deal. A seller who needs the money moving before you can check anything is usually the one with something that will not survive the check. The Kairos rule is published and checkable: Funds release only after the full amount is funded in escrow, the APA is signed, every critical asset is handed over, and the buyer confirms the transfer. Our fee is auto-deducted at that moment, before the seller is paid. The full amount there means the full purchase price, never a deposit or a partial wire. A seller or a platform pushing you toward a direct wire, an off-platform payment, or a shortcut around that sequence is answering the legitimacy question with their own behavior, no matter how convincing the business itself looks. Ask which of those steps happens before your money moves, on any marketplace you buy through - if the answer is trust us, that is the answer.
