L/C adds bank document control; T/T is faster/cheaper but trust-based.

Key Differences at a Glance

L/C uses banks to pay against compliant documents under UCP rules. T/T transfers cash directly when buyer initiates wire — no automatic document gate.

Seller vs Buyer Obligations

L/C protects seller if documents perfect; T/T favors seller only when buyer pays advance or reputable relationship exists.

L/C lets buyer delay payment until bank accepts docs; T/T often requires advance — buyer bears non-delivery risk on prepayment.

Risk Transfer and Cost Structure

L/C risk = discrepancy, fraud docs, bank/country risk. T/T risk = buyer default before pay or seller non-performance after pay.

L/C bank fees higher (opening, confirmation, negotiation). T/T mainly SWIFT and FX spread.

Which Term to Choose

Use L/C for new markets, weak buyer credit, or regulatory requirement. Use T/T for trusted partners, samples, or repeat low-dispute trade.

Examples

LC win

USD 500k first order to new distributor — LC at sight reduces seller exposure.

TT win

5-year OEM partner — monthly T/T saves USD 800/month LC fees.

FAQ

Combine LC and TT?
Sometimes deposit T/T + balance LC — spell clearly in contract.
LC then TT for amendments?
Amendment fees add up — consider TT for small repeat orders.
Which for services?
T/T common; standby LC for performance.
eUCP digital docs?
Electronic records under eUCP — still mainly LC channel.
Sanctions screening?
Both paths hit bank compliance — factor delay.
