Payment Terms in International Trade: T/T, L/C, D/P and D/A Explained

The payment method you agree with a supplier is not a financial detail — it is the risk contract of your entire transaction. It decides who is exposed if the goods are late, defective, or never shipped, and who bears the cost if the buyer delays or defaults. Understanding the four standard methods is essential before you negotiate any international order.

T/T (Telegraphic Transfer) — A bank wire transfer, usually split as a deposit and a balance payment. The most common structure in Asian manufacturing is 30% deposit with the order and 70% balance against a copy of the bill of lading. T/T is fast and cheap, but it gives the buyer almost no leverage once the deposit is paid — your recourse is the supplier’s goodwill.

L/C (Letter of Credit) — A bank promises to pay the seller when they present compliant documents (invoice, bill of lading, inspection certificates) that prove shipment. An irrevocable, confirmed L/C is the safest method for both parties: the seller is guaranteed payment against documents, and the buyer is guaranteed the documents match the terms before payment. The cost — bank fees of roughly 0.5–2% of the order value plus cash collateral requirements — makes L/C most suitable for large or first-time transactions.

The L/C trap: documents, not goods — Banks examine documents, not cargo. If the goods arrive damaged but the bill of lading is clean, the bank still pays. That is why L/C buyers should always pair letters of credit with a pre-shipment inspection and a quality clause — the documents are only as good as the checks behind them.

D/P (Documents against Payment) — The buyer’s bank releases the shipping documents only when the buyer pays the draft at sight. D/P is cheaper than an L/C and gives the buyer control of documents without upfront payment. However, the seller carries significant risk: if the buyer refuses the documents, the seller must absorb return freight or sell the goods elsewhere.

D/A (Documents against Acceptance) — The buyer accepts a time draft and receives the documents, promising to pay at a future date (typically 30–90 days). D/A is effectively unsecured trade credit — the buyer gets the goods now and pays later, and the seller has little practical recourse if payment never arrives. It should only be offered to long-term, trusted partners.

Choosing the right structure — New relationships: L/C or T/T with deposit, plus a pre-shipment inspection. Growing relationships: 30/70 T/T with balance against shipping documents. Mature partnerships: open account or D/A with credit limits. The general principle is to reduce risk exposure in proportion to the trust you have actually earned — not the trust the supplier claims to deserve.

Also remember the hidden costs of payment: wire fees, exchange rate spreads, and L/C amendment charges all belong in your total cost calculation. A supplier who quotes a low price but demands payment methods with expensive compliance burdens may not be the bargain they appear.
