The ultimate warning sign: If a supplier refuses cards or escrow and only pushes for non-reversible payment methods, walk away immediately. This is the number one sign of a scam. Either insist on escrow or drop the deal.
Double-check the names: The name on the bank account must perfectly match the officially registered company name. If it doesn't, stop right there.
First-time orders: Always use an independent escrow service for your first order. This ensures the supplier only gets paid after you have the goods in hand.
