Trade Finance And Documentary Credits
Sight Letter Of Credit vs Usance Letter Of Credit: Differences, Costs, Risks, And When To Use Each
A sight letter of credit is designed to pay once compliant documents are presented and accepted. A usance letter of credit, also called a deferred payment or time letter of credit in many transactions, pays at a future maturity date. The practical difference is cash timing. The commercial difference is who carries that timing burden and at what cost.
Many businesses treat the choice between sight and usance terms as a minor drafting decision. It is not. This is one of the most important economic choices in a documentary credit transaction because it shapes working capital, supplier leverage, discounting needs, and the final cost of the trade.
Put simply, a sight LC is better for sellers who want to get paid quickly after shipping and presenting compliant documents. A usance LC is better for buyers who need time to sell, process, or distribute the goods before settlement falls due. That extra time can make a trade workable, but it is never free.
Commercial reality:
a usance letter of credit does not remove financing cost. It shifts it. The exporter may build the delay into pricing, request discounting, or require stronger terms elsewhere in the deal.
What A Sight Letter Of Credit Means
Under a sight LC, payment is due once the bank determines that the presentation is compliant under the credit terms. In theory, that means fast settlement after shipment and document examination. In practice, the exact timing depends on the bank chain, document quality, and whether any discrepancies appear.
This structure is often preferred by exporters because it shortens the cash-conversion cycle. The seller ships, presents, and expects payment without having to carry the receivable for a longer tenor.
Why Sellers Prefer Sight LCs
The exporter does not want to finance the buyer’s working-capital needs and wants quicker access to sale proceeds after compliant presentation.
Where Sight LCs Fit Best
They are common where the supplier has leverage, the goods are in strong demand, or the seller wants to minimise post-shipment credit exposure.
What A Usance Letter Of Credit Means
Under a usance LC, payment is due at a future date, for example 30, 60, 90, or 180 days after shipment, bill of lading date, presentation, or another date specified in the credit. The seller still needs a complying presentation, but actual cash is delayed until maturity.
This structure is often used when the buyer needs time. That might be because the goods must be imported, warehoused, processed, or resold before enough cash is available to settle the underlying obligation.
Why Buyers Prefer Usance LCs
They get more time to manage inventory turnover, collections, or downstream resale before payment falls due.
Where Usance LCs Fit Best
They are common in import, commodity, and distribution trades where the buyer’s commercial cycle needs breathing room.

Which One Costs More?
There is no universal answer, but usance structures usually create more economic friction because somebody is financing the delayed payment period. That can show up as a higher product price, discounting cost, confirmation cost, or a broader trade finance charge somewhere else in the transaction.
Businesses sometimes compare only the LC issuance fee and miss the bigger economic picture. The more useful question is this: once payment timing is delayed, who is carrying that exposure and how are they being compensated for it?
Common mistake:
buyers sometimes ask for usance terms assuming the seller will absorb the delay quietly. Strong sellers usually do not. They either raise the price, tighten other terms, or expect a bankable discounting path.
Risk Differences Between Sight And Usance Structures
For The Seller
A sight LC reduces the period during which cash is tied up. A usance LC increases exposure to timing, liquidity, and sometimes bank or country risk if confirmation is not added.
For The Buyer
A sight LC compresses the buyer’s working-capital cycle. A usance LC gives breathing room but may make the trade more expensive overall.
For Financing Parties
Usance structures create clearer scope for discounting, acceptance, or other receivables-led financing discussions, provided the bank and credit wording are acceptable.
For The Transaction
The longer the time between compliant presentation and payment, the more important the bank risk, country risk, and documentation quality become.
When A Sight LC Makes More Sense
- The seller has stronger negotiating leverage
- The exporter wants fast liquidity after shipment
- The goods are in demand and the supplier does not need to offer extra time
- The margin is tight and cannot comfortably absorb delayed-payment economics
When A Usance LC Makes More Sense
- The buyer needs time to sell or process the goods
- The transaction requires built-in trade credit from the supplier side
- The exporter is willing to wait or has a viable discounting route
- The trade still works economically after timing cost is included
Practical lesson:
the right structure is the one that still works after you include funding cost, not the one that looks more attractive in isolation.
How Discounting Fits In
One reason usance LCs remain popular is that the seller may still be able to accelerate cash through discounting. If the issuing bank, wording, and document presentation are acceptable, the future payment can sometimes be discounted so the exporter gets liquidity earlier while the buyer still benefits from delayed settlement.
That is why the discussion does not stop at “sight versus usance.” It often extends into the broader trade finance structure, including whether the receivable can be financed efficiently and whether the bank chain is acceptable for that purpose.
Where Financely Fits
For many clients, the real issue is not simply choosing sight or usance language. It is making sure the structure still works commercially once the timing, cost, and payment route are viewed together. A transaction that looks attractive on paper can become uneconomic once the delayed-payment burden is properly priced.
That is why this discussion often overlaps with broader trade finance structuring
and asset-based lending and underwriting
, especially where supplier credit, receivables timing, or post-shipment liquidity are part of the deal.

Frequently Asked Questions
What is a sight letter of credit?
It is a documentary credit designed to pay once compliant documents are presented and accepted under the credit terms.
What is a usance letter of credit?
It is a documentary credit that pays at a future maturity date, giving the buyer additional time before settlement is due.
Is usance always cheaper for the buyer?

Can a usance LC be discounted?
Sometimes yes, depending on the issuing bank, the wording, the document presentation, and the broader financing structure.
