Trade Finance & Payment
Open Account
Also known as: O/A, Open Account Terms
Open account is a sale in which the exporter ships the goods and sends the invoice with payment due at a later agreed date — commonly thirty, sixty, or ninety days after shipment or delivery — extending unsecured credit to the buyer. It is the most buyer-friendly and competitive payment method and dominates trade between trusted partners and within supply chains, but it places the risk of non-payment squarely on the seller. Exporters mitigate that risk with credit insurance, factoring, or supply-chain finance, turning the receivable into cash or transferring the default risk to a third party.
The dominant term in established trade, and pure credit risk on the seller. From a customs standpoint it is the cleanest arrangement there is — the price paid or payable is exactly what the invoice says, with no financing structure to unpick.
