Most fraud guides teach buyers how to avoid fake suppliers. Sellers face the mirror image: fake buyers, forged payment proofs, diverted shipments and chargebacks. In phone wholesale, where one lot can be worth tens of thousands, a single bad buyer can wipe out several clean deals.
A buyer who disappears after receiving goods, or who disputes a card payment after delivery, hits a seller with two losses: the stock is gone and the payment is clawed back. Because wholesale moves on trust and speed, sellers often skip the verification steps that would catch a fraudster. The fix is a short, non-negotiable sequence: verify the buyer, then extend credit, then ship — in that order, every time.
None of these proves fraud on its own, but any two together should stop you from releasing stock. The goal is not to become suspicious of everyone; it is to make the verification steps automatic so a fraudster has to work harder than an honest buyer ever would.
Run know-your-business checks before you quote a real price or extend terms. Verify the company exists, confirm the buyer's identity and authority to purchase, screen sanctions and restricted-party lists, and record the result. A buyer who resists basic verification is a red flag, not a busy person. Our buyer onboarding guide walks through the full KYB sequence, and credit limits should reflect what a buyer has earned, not what they promise.
Confirm funds have cleared your own account before releasing stock, not when a receipt arrives. For card payments, require address and CVV match and be alert to mismatched billing and shipping. For wire transfers, wait for the funds to settle in your account. A payment proof is a promise; cleared funds are a fact — and only cleared funds protect you when a buyer later disputes the charge.
Ship only to the verified business address on the contract. Treat any last-minute change of receiver or destination as a red flag requiring re-verification. Use tracked, signed-for delivery and keep the proof of delivery with the IMEI manifest, so a "never arrived" claim can be answered with evidence. A clean chain-of-custody record proves exactly what left and where it went.
Put the buyer's verified details, the payment method, the delivery address and the dispute window into the purchase order. A clean document trail — invoice, IMEI packing list, signed delivery proof and a cleared-funds record — turns a fraud claim into a winnable dispute. For ongoing buyers, a defined accounts-receivable discipline keeps credit exposure visible instead of accumulating quietly.
