If a supplier only accepts methods you cannot reverse and refuses card or escrow, that is the number one scam signal. Walk away or use escrow.
The bank account name must match the registered company name. If it does not, stop.
For a first order, use an independent escrow service so the supplier is paid only after you receive the goods.
