This page teaches how a letter of credit protects a factory and states exactly what a bank promises, and to whom

A letter of credit is a bank's own written promise to pay the seller a fixed sum once the seller presents documents matching the credit's own terms exactly. Anyone at a factory taking an order paid this way, a merchandiser confirming payment security before committing fabric, or an owner deciding whether to accept a new buyer's order, needs to know what that promise covers and what it does not.

Delta Garments meets this every time Northline Apparel places an order under a letter of credit, as Order B (the jeans)'s own fixed terms require. Mona, the merchandiser, cannot treat "the buyer opened a letter of credit" as the end of the question; she must know which bank made the promise and what could still go wrong even with one in place.

Without this skill, a factory can commit fabric and production against a payment method it believes is guaranteed, only to find later that the guarantee depends on conditions it never checked. This lesson states the rule a letter of credit follows and works through Order B (the jeans)'s own letter of credit as Delta Garments receives it.

03Before you start

You need: Track 15 Course 1 on payment methods, since this course builds directly on the payment-method spectrum already taught there; a letter of credit sits at the safer end of that spectrum for the seller.

By the end of this lesson you can:

  • state what a letter of credit actually promises, and to whom;
  • name the four parties a letter of credit usually involves and what each one does;
  • explain why the promise is a bank's own promise, not the buyer's;
  • recognise the one condition on which the whole promise depends;
  • identify Order B (the jeans)'s own letter of credit correctly against this rule.

Not covered here: reading a letter of credit's own detailed terms, such as its dates and its required documents, is lesson 15.2.2's own subject; discrepancies are lesson 15.2.3's own subject.

04Key terms

Words you will meet in this lesson

TermMeaning
Letter of creditA bank promise to pay the factory once the shipping documents match the order.
Issuing bankThe bank that opens a letter of credit on the buyer's own instruction, promising to pay once compliant documents are presented.
Advising bankThe bank in the seller's own country that receives the letter of credit from the issuing bank and passes it to the seller, confirming it is genuine.
Confirming bankA bank that adds its own promise to pay to a letter of credit already opened by the issuing bank, so the seller has two banks' promises instead of one.
BeneficiaryThe party named in a letter of credit who is entitled to be paid once its documents comply, usually the seller or factory.
ApplicantThe party who instructs its own bank to open a letter of credit, usually the buyer, and who must pay the bank back once it honours the credit.
05Teaching
The rule

A letter of credit is a bank's own promise, separate from the buyer's own promise, to pay a fixed sum once the beneficiary presents documents that comply with the credit's own terms

Once a buyer's bank opens a letter of credit, the bank itself, not the buyer, owes the payment, provided the beneficiary's documents match what the letter of credit states. This is the whole reason a letter of credit exists: it moves the seller's payment risk away from "does this buyer pay its bills" and onto "does a named bank keep its own written promise," which is a far safer question for a factory to answer, since banks are regulated and their promises are governed by internationally standard rules for letters of credit. The promise is conditional, not unconditional: it depends entirely on the documents complying, and on nothing else the buyer or factory might separately agree between themselves.

ApplicantNorthlineIssuing bankBuyer's bankAdvising bankSeller's bankBeneficiaryDelta Garments
The issuing bank's own promise flows to the beneficiary through the advising bank, not through the applicant. Delta Garments is paid by a bank's written promise, not by Northline directly asking its own bank to send money.
What you meet in real life

A letter of credit's own structure is fixed, but who plays each part, and how many banks are involved, differs by order

What can differThe shapes you will meetWhy it matters
A new buyer relationship, export, made to order, such as Order B (the jeans) for Northline ApparelThe issuing bank is a bank the factory has never dealt with before, so the factory's own bank may be asked to add a confirmation.A confirming bank gives the factory a second, closer promise to rely on, useful when the issuing bank's own country carries more risk.
A long-standing buyer relationship, export, made to orderThe same issuing bank opens letters of credit for many orders in a row, so the factory already trusts its record of paying on compliant documents.Confirmation is requested less often once a bank's own payment record is proven, saving the confirming bank's own fee.
A domestic sale, such as Cedar & Co.'s own purchases from Delta GarmentsNo letter of credit is used at all; Cedar & Co. buys on 60-day open account instead.A letter of credit is a cross-border tool built for buyers and sellers who do not already trust each other directly; it is largely irrelevant to a domestic relationship built on an ongoing account.
A hosiery, terry or home-textile order rather than a cut-and-sew garment orderThe same four-party structure and the same conditional bank promise apply; only the shipped goods and their own documents differ.Confirms the letter of credit's own structure is general to any exported, made-to-order goods, not specific to garments.
The case we follow

Northline Apparel's own bank opens a letter of credit naming Delta Garments as the beneficiary of Order B

Sara, the buyer at Northline Apparel, instructs Northline's own bank to open a letter of credit for Order B, the five-pocket jeans, at Order B's own fixed buyer target FOB of USD 9.80 per piece for 3,000 pieces. Northline's own bank, the issuing bank, sends the letter of credit to a bank in Egypt, the advising bank, which passes it to Delta Garments, the factory, named in the letter of credit as the beneficiary. Mona checks that the advising bank has confirmed the letter of credit is genuine before Delta Garments commits any fabric to Order B.

The worked number

The order value Order B (the jeans)'s own letter of credit places at risk if the issuing bank ever fails to keep its promise

Order B's own fixed figures give the total value the letter of credit covers, and the portion already committed to fabric once cutting begins.

Order B's own total order value covered by the letter of credit:
USD 9.80 per piece × 3,000 pieces = USD 29,400
Order B's own denim cost committed once fabric is cut, from docs/02 section 7:
1.45 m per piece × USD 3.20 per metre = USD 4.64 per piece
USD 4.64 × 3,000 pieces = USD 13,920 already committed to denim alone
USD 13,920 denim (47%)Remaining order valueUSD 29,400 total order value under the letter of creditthe whole sum depends on one bank keeping its own written promise
Nearly half of Order B's own order value is already spent on denim before the letter of credit's own promise is ever tested. A factory that has not checked which bank made the promise is exposed on the full USD 29,400, not only the denim share.
The method

How to confirm a letter of credit actually protects your factory before committing production to it

  1. Identify all four parties named in the letter of credit: the applicant, the issuing bank, the advising bank, and the beneficiary.
  2. Confirm the advising bank has verified the letter of credit is genuine, not merely forwarded a document it has not checked.
  3. Check the issuing bank's own record and country, and decide whether to ask for a confirming bank if the issuing bank is unfamiliar or based in a higher-risk country.
  4. Read what sum and what currency the letter of credit actually promises, and match it against the order's own agreed price before committing fabric.
  5. Note that the promise is conditional on compliant documents, not a guarantee that payment happens automatically once goods ship.
  6. Keep the letter of credit's own reference number on file and quote it on every document prepared for presentation.
The trap

Treating "the buyer opened a letter of credit" as proof that payment is already guaranteed

A common mistake is committing fabric and production to an order as soon as a factory hears a letter of credit has been opened, without checking which bank issued it, whether it has been advised through a bank the factory trusts, or what documents it actually requires. A letter of credit from an unfamiliar issuing bank, unconfirmed, still depends on that one bank's own promise being honoured and on the factory's own documents complying exactly; skipping this check does not remove the risk, it only hides it until the goods are already shipped.

06In plain words

A letter of credit is a written promise from a bank, not from the buyer, that says: pay this named seller a fixed amount once it hands over the right shipping papers. The buyer's own bank makes the promise, another bank in the seller's own country usually passes it along and checks it is real, and sometimes a second bank adds its own promise on top for extra safety. The whole promise only works if the seller's papers match exactly what the letter says; nothing else the buyer and seller agreed between themselves on the side changes that. For Delta Garments, this means checking who actually made the promise and what it depends on before committing a single metre of Order B's own denim, not simply trusting that a letter of credit means the money is already safe.

07Quick check
  • A letter of credit is a bank's own promise, not the buyer's own promise, to pay a fixed sum.
  • The promise is conditional: it depends entirely on the beneficiary's documents complying with the letter of credit's own terms.
  • Four parties are usually involved: the applicant, the issuing bank, the advising bank, and the beneficiary.
  • A confirming bank adds a second bank's own promise, most useful with an unfamiliar issuing bank or a higher-risk country.
  • Order B (the jeans)'s own letter of credit covers USD 29,400 in total order value, at USD 9.80 per piece for 3,000 pieces.
  • A letter of credit is a cross-border tool; it is not used on a domestic open-account relationship such as Cedar & Co.'s own account with Delta Garments.
08Workplace scenario

Mona is asked to start cutting Order B's own denim the same day Sara tells her the letter of credit has been opened

Sara, the buyer at Northline Apparel, emails Mona to say Northline has instructed its own bank to open the letter of credit for Order B and asks Delta Garments to start cutting immediately so the timeline is not lost.

  • Mona has not yet received the letter of credit itself from any bank, only Sara's own email.
  • Order B's own denim cost committed once cutting begins is USD 13,920, from this lesson's own worked number.
  • Delta Garments has no direct relationship with Northline's own issuing bank and has not used it before.
  • Cutting cannot be reversed once the denim is cut to the pattern; the fabric cost is lost if the letter of credit never actually arrives as described.

The document Mona reads:

Sara's email: "Our bank has opened the L/C for Order B. Please start cutting today so we keep to the 22-week production timeline."

Should Mona instruct cutting to begin today, or wait for the advising bank to confirm the letter of credit has actually been received and verified? Decide before opening the answer.

Show decision

Mona should wait for the advising bank's own confirmation before instructing cutting to begin.

First fact. A buyer's own email stating a bank "has opened" a letter of credit is not the same as the letter of credit itself arriving at a bank Delta Garments trusts; the promise this lesson describes is a bank's own promise, not the buyer's own word.

Second fact. Cutting Order B's own denim commits USD 13,920 that cannot be recovered once the fabric is cut to pattern; committing it against an unverified claim exposes that whole amount to the small but real chance the letter of credit never arrives as described, or arrives with terms Delta Garments cannot meet.

Waiting for the advising bank's own confirmation costs at most a few days against a 22-week production timeline; cutting early against an unverified letter of credit risks USD 13,920 of fabric that Northline has no obligation to pay for until a real, confirmed letter of credit exists.

09What it costs

The order value exposed if Delta Garments commits production before a letter of credit is actually confirmed

Order B's own total order value under its letter of credit is USD 29,400 (9.80 × 3,000, from this lesson's own worked number), and USD 13,920 of that is already at risk in denim alone once cutting begins. Against a fixed FOB target of USD 9.80 per piece, committing that fabric before the advising bank confirms the letter of credit is genuine risks the full USD 13,920, about 47% of Order B's own total order value, for the sake of saving a few days against a 22-week production timeline.
