Usance and Acceptance LCs Are Not the Same Thing
A usance letter of credit
gives the buyer time before payment is due. An acceptance letter of credit
is a more specific structure in which a bank accepts a time draft drawn by the beneficiary and becomes obligated to pay that draft at maturity.
That distinction matters. In commercial conversation, people often compare "usance LC" and "acceptance LC" as if they were opposite products. Technically, an acceptance credit can itself be a form of usance or time credit because payment still falls due at a future date.
Under UCP 600, a documentary credit must state whether it is available by sight payment, deferred payment, acceptance or negotiation. "Usance" describes the future payment tenor; "acceptance" describes one specific method by which the bank honours that future-dated obligation.
The Key Difference
In a deferred-payment usance LC, the bank incurs a deferred payment undertaking and pays at maturity. A bill of exchange is not required simply to create that deferred payment obligation.
In an acceptance LC, the beneficiary draws a time draft on the bank. The bank accepts that draft and undertakes to pay it at maturity.
Usance
Describes payment at a future maturity rather than immediate settlement at sight.
Deferred payment
The bank undertakes to pay at maturity without requiring an accepted time draft.
Acceptance
The beneficiary draws a time draft and the relevant bank accepts it for payment at maturity.
Discounting
Both deferred payment undertakings and accepted drafts may support pre-maturity financing.
What Does Usance Mean in a Letter of Credit?
In trade finance, usance
refers to a period of time allowed before payment becomes due.
A usance LC may therefore provide payment 30, 60, 90, 120, 180 days or another agreed period after a defined event.
The maturity basis can be linked to:
- the bill of lading date;
- shipment date;
- the date of presentation;
- sight of documents;
- invoice date;
- another clearly defined contractual date.
The crucial point is that usance describes timing. It does not, by itself, tell you whether the documentary credit is available by deferred payment, acceptance or another permitted method.
For a broader treatment of payment-tenor structures, see our usance letter of credit guide.
What Is an Acceptance Letter of Credit?
An acceptance LC is a documentary credit available by acceptance.
The beneficiary presents the stipulated commercial documents together with a time draft or bill of exchange
drawn on the bank identified in the credit.
If the presentation complies and the bank is obligated to honour, the relevant bank accepts the draft. Acceptance converts the draft into an obligation of the accepting bank to pay the amount at its maturity date.
Banker's acceptance:
when a bank accepts the bill of exchange, the resulting instrument is commonly referred to as a banker's acceptance. It can potentially be held until maturity or sold or discounted before maturity.
Usance LC vs Acceptance LC Comparison
| Feature |
Deferred-Payment Usance LC |
Acceptance LC |
| Payment timing |
Payment occurs at a future maturity. |
Payment occurs at the maturity of the accepted time draft. |
| UCP 600 availability |
Available by deferred payment. |
Available by acceptance. |
| Time draft required |
No draft is required merely to create the deferred payment undertaking. |
Yes. Acceptance involves a bill of exchange drawn by the beneficiary. |
| Bank obligation |
The relevant bank incurs a deferred payment undertaking and pays at maturity. |
The relevant bank accepts the draft and pays it at maturity. |
| Evidence of future claim |
The deferred payment undertaking exists under the documentary credit structure. |
The accepted time draft is a distinct payment instrument evidencing the accepting bank's obligation. |
| Pre-maturity financing |
The deferred payment undertaking may be prepaid or purchased by an eligible bank. |
The accepted draft may be discounted before maturity. |
| Administrative burden |
Generally avoids the need to create and process a bill of exchange. |
Requires the beneficiary to prepare the draft correctly and the bank to accept it. |
| Typical commercial objective |
Give the importer payment terms while preserving a bank-backed maturity obligation. |
Create a future-dated bank acceptance that can be held or financed before maturity. |
Important:
an acceptance LC is not the opposite of a usance LC. An acceptance LC normally has a usance tenor itself. The more technically accurate comparison is often deferred-payment LC vs acceptance LC.
How UCP 600 Treats Deferred Payment and Acceptance
UCP 600 defines different methods by which a documentary credit can be made available.
A credit can be available by:
- sight payment;
- deferred payment;
- acceptance;
- negotiation.
Under the UCP 600 definition of honour:
- a sight credit is honoured by paying at sight;
- a deferred-payment credit is honoured by incurring a deferred payment undertaking and paying at maturity;
- an acceptance credit is honoured by accepting a bill of exchange drawn by the beneficiary and paying it at maturity.
This distinction is fundamental when drafting the availability field of a documentary credit. Our UCP 600 guide
covers the wider rules governing documentary credits.
Current ICC Practice Favors Simpler Deferred Payment Structures
ICC guidance has recommended that banks use deferred-payment availability for usance documentary credits instead of requiring drafts by acceptance unless there is a specific commercial, regulatory or legal reason to create a banker's acceptance.
That matters because many transactions do not gain anything economically from creating a separate time draft when a deferred payment undertaking already achieves the required maturity structure.
How a Deferred-Payment Usance LC Works
A deferred-payment LC gives the buyer a future payment maturity without requiring the beneficiary to draw a bill of exchange simply to establish the bank's payment obligation.
- The documentary credit is issued.
The LC states that it is available by deferred payment and defines the maturity basis, such as 90 days after the bill of lading date.
- The seller ships the goods.
The beneficiary prepares the documents required by the LC.
- A complying presentation is made.
The documents are presented to the nominated, confirming or issuing bank as applicable.
- The future payment obligation is established.
The relevant bank incurs the deferred payment undertaking according to the credit.
- Payment occurs at maturity.
The bank pays the amount due on the agreed maturity date.
This structure is covered in more depth on our deferred-payment letter of credit
page.
How an Acceptance LC Works
Acceptance uses a different mechanism because the beneficiary must draw a time draft.
- The LC is issued available by acceptance.
The credit identifies the bank on which the beneficiary must draw the time draft and establishes the required tenor.
- The beneficiary ships and presents.
Commercial documents and the required time draft are presented under the credit.
- The bank determines compliance.
If the presentation complies and the bank must honour, the bank accepts the draft.
- The accepted draft becomes payable at maturity.
The accepting bank becomes obligated to pay the accepted amount on the due date.
- The beneficiary chooses whether to wait or finance.
The accepted draft may be held until maturity or, where a bank is willing, discounted before maturity.
Example of the Difference in a USD 5 Million Trade
Assume an importer purchases USD 5 million of equipment and negotiates 120-day payment terms with the exporter.
Deferred-Payment Usance LC
The buyer's bank issues a USD 5 million LC available by deferred payment at 120 days from the bill of lading date.
The seller ships and makes a complying presentation. The bank incurs its deferred payment undertaking. USD 5 million becomes payable at maturity.
No acceptance draft is required merely to create that future payment obligation.
Acceptance LC
The buyer's bank issues a USD 5 million LC available by acceptance at 120 days from the bill of lading date.
The seller presents the required documents plus a 120-day time draft. The bank accepts the draft after determining that the presentation complies.
The accepted USD 5 million draft is payable by the accepting bank at maturity.
Can Usance and Acceptance LCs Be Discounted?
Yes, but the financing mechanics are different.
Deferred-Payment LC Discounting
Under UCP 600, when a nominated bank is authorized to incur a deferred payment undertaking, the issuing bank also authorizes that nominated bank to prepay or purchase the undertaking it has incurred.
In commercial terms, this can allow the exporter to receive money before the contractual maturity rather than waiting through the full usance period.
Acceptance LC Discounting
Once a bank has accepted the time draft, the beneficiary holds a banker's acceptance payable at maturity. Subject to bank appetite and applicable law, that accepted draft can potentially be discounted.
Discount pricing can depend on:
- the issuing or accepting bank;
- the maturity period;
- country and transfer risk;
- whether the credit is confirmed;
- currency and funding rates;
- transaction documentation;
- whether the financing is with or without recourse;
- the financing bank's balance-sheet appetite.
For execution mechanics, see our usance letter of credit discounting
page and our broader letter of credit discounting
service page.
Where UPAS Fits
UPAS
stands for Usance Payable at Sight.
It is designed to solve a common commercial conflict:
- the importer wants 90, 120 or 180 days to pay;
- the exporter wants cash at or shortly after compliant presentation.
In a properly structured UPAS transaction, a financing or nominated bank pays the seller at sight while the importer retains the agreed usance period. The financing bank is then repaid according to the agreed maturity structure.
UPAS is not simply another name for an acceptance LC.
It describes an economic result in which the seller receives sight proceeds while the buyer receives usance terms. The underlying LC availability and bank financing structure must still be drafted correctly.
See our UPAS letter of credit guide
and UPAS and usance LC financing
page for the wider structure.
Usance LC Maturity Must Be Defined Precisely
Many problems attributed to the type of LC are actually maturity-calculation problems.
A credit should clearly state both the tenor and the date from which the tenor runs.
| Wording |
How Maturity Is Determined |
| 90 days after bill of lading date |
Maturity is calculated from the date of the relevant transport document. |
| 120 days after shipment |
The operative shipment date must be identifiable from the documentary presentation. |
| 60 days after sight |
The credit needs clear mechanics for determining the relevant sight date. |
| 180 days after invoice date |
Maturity is linked to the date of the commercial invoice where the credit permits that basis. |
Avoid vague tenor wording."90 days usance" is incomplete if the credit does not clearly establish the event from which the 90 days are calculated.
How the LC Is Reflected in MT700
The documentary credit must identify how it is available and with which bank.
The availability section should be consistent with the intended structure. A deferred-payment credit should not casually include acceptance language or a time draft where the parties do not actually intend to create a banker's acceptance.
Likewise, if the commercial structure genuinely requires acceptance, the credit must identify the correct drawee and tenor.
See our MT700 guide
for the wider documentary credit message structure.
Credit Risk in Deferred Payment and Acceptance LCs
Both structures can provide the exporter with bank risk rather than pure unsecured buyer risk, but the form of the bank obligation differs.
Deferred Payment Risk
The beneficiary relies on the relevant bank's deferred payment undertaking under the credit. Where confirmation has been added, the confirming bank may also have its own obligation under the confirmed credit.
Acceptance Risk
Once the relevant bank accepts the beneficiary's time draft, the beneficiary or subsequent holder relies on the accepting bank for payment at maturity.
If the issuing bank or its country is the principal concern, confirmation may be more important than whether the credit uses acceptance or deferred-payment mechanics. See our confirmed vs unconfirmed letter of credit
comparison.
Deferred Payment vs Acceptance vs Negotiation
These concepts are frequently mixed together, but UCP 600 treats them differently.
| Availability |
Bank Action |
Payment Timing |
| Deferred Payment |
Bank incurs a deferred payment undertaking. |
At maturity. |
| Acceptance |
Bank accepts a bill of exchange drawn by the beneficiary. |
At maturity. |
| Negotiation |
Nominated bank purchases drafts and/or documents under a complying presentation. |
Beneficiary receives funds on or before reimbursement is due. |
For the third structure, see our letter of credit by negotiation guide.
Should You Use Deferred Payment or Acceptance?
Deferred Payment May Be Preferable When
- the commercial objective is simply to give the importer time to pay;
- there is no legal or regulatory reason to create a bill of exchange;
- the banks prefer simpler documentary mechanics;
- the future payment undertaking can be financed without an accepted draft;
- UPAS or another funded usance structure will be used.
Acceptance May Be Appropriate When
- a banker's acceptance is specifically required;
- local law or market practice favors bills of exchange;
- the exporter or financing bank wants an accepted time draft;
- the market has an established financing channel for banker's acceptances;
- the commercial documentation already relies on draft-based settlement.
For Most Transactions, Start With the Commercial Objective
If the buyer wants 90 or 120 days and the seller is willing to receive payment at maturity, a deferred-payment LC may be sufficient.
If the seller needs immediate proceeds, evaluate discounting or a UPAS structure. If there is a genuine requirement for banker's acceptance paper, then acceptance may be justified.
Common Drafting Mistakes
Mixing Acceptance and Deferred Payment
The LC says "deferred payment" in one section but requires a time draft for acceptance elsewhere without explaining the intended structure.
Undefined Tenor Start
The credit states "90 days" without identifying whether the period runs from shipment, bill of lading date, sight or another event.
Wrong Drawee
An acceptance credit must identify the correct bank on which the beneficiary is required to draw the draft.
Financing Added Too Late
The parties agree usance terms and only after issuance discover that the exporter expected sight proceeds or discounting.
Documentary defects can create additional problems after shipment. See our common LC discrepancies under UCP 600
page.

Usance and Acceptance LC FAQ
What is the difference between a usance LC and an acceptance LC?
Usance describes a future payment tenor. An acceptance LC is a specific type of time credit in which the beneficiary draws a time draft and the relevant bank accepts that draft for payment at maturity.
Is an acceptance LC a type of usance LC?
Yes, in ordinary commercial terminology an acceptance LC can have a usance tenor. Under UCP 600, however, "acceptance" is the formal method of availability, while usance describes the fact that payment is deferred to a future date.
Does a usance LC require a bill of exchange?
Not necessarily. A documentary credit available by deferred payment can create a future payment obligation without requiring a bill of exchange. A draft is central to a credit available by acceptance.
What is a banker's acceptance?
A banker's acceptance is a time draft that has been accepted by a bank. Acceptance creates an obligation of the accepting bank to pay the draft at maturity.
Can a deferred-payment LC be discounted?
Yes, subject to bank appetite and the structure of the credit. UCP 600 permits a nominated bank authorized to incur a deferred payment undertaking to prepay or purchase the undertaking it has incurred.
Can an acceptance LC be discounted?
Potentially. Once a bank accepts the beneficiary's time draft, the accepted draft may be financed or discounted by a bank willing to purchase it before maturity.
What is the difference between usance and UPAS?
A normal usance LC provides future payment terms. A UPAS structure is designed so that the seller receives sight proceeds while the importer retains the agreed usance period and ultimately reimburses according to the financing structure.
What is better, deferred payment or acceptance?
Neither is universally better. Deferred payment is generally simpler where there is no reason to create a time draft. Acceptance may be appropriate where a banker's acceptance is required for legal, regulatory, commercial or financing reasons.
What is a 90-day usance LC?
It is a documentary credit under which payment is due 90 days after the event specified in the credit, such as the bill of lading date or another clearly defined maturity trigger.
Who pays the financing cost on a usance LC?
That depends on the commercial agreement and financing structure. The importer may bear the funding cost, the exporter may accept a discount from proceeds, or costs may be allocated through the LC charges clause or separate financing agreement.
Can a usance LC be confirmed?
Yes. A confirming bank can add its own undertaking to a qualifying documentary credit, including a deferred-payment or acceptance structure, subject to its approval and the terms of the credit.
