Documentary credits and documentary collections are the primary instruments for managing payment risk in international trade. Despite the growth of open account trading, letters of credit and documentary collections remain essential for UK businesses trading with new buyers, higher-risk markets, or counterparties where payment certainty is required. Understanding how each instrument works, when to use it, and how to administer it efficiently is a practical necessity for UK businesses with international operations.

How letters of credit work
A documentary letter of credit (LC) is an irrevocable commitment from the buyer's bank to pay the seller (the UK exporter) upon presentation of specified documents that demonstrate the goods have been shipped in accordance with the contract terms. The seller ships the goods, prepares the required documents (bill of lading, commercial invoice, packing list, certificate of origin, etc.), and presents them to their bank, which forwards them to the issuing bank. Payment follows upon document verification.
The irrevocability of the LC is its central value: once issued and accepted, neither the buyer nor their bank can unilaterally cancel it. The risk of buyer insolvency or payment refusal is effectively transferred to the buyer's bank. For UK exporters selling to buyers in markets with political or currency instability, this bank guarantee is the primary protection against non-payment.
Documentary collections: a lighter alternative
Documentary collections (D/C) are less expensive but offer less protection than LCs. In a D/C, the UK seller's bank sends shipping documents to the buyer's bank with instructions to release them only against payment (Documents against Payment, D/P) or against acceptance of a bill of exchange (Documents against Acceptance, D/A).
The key difference from an LC is that in a D/C, the buyer's bank does not guarantee payment - it merely acts as an agent. If the buyer refuses to pay or accept the bill of exchange, the documents (and therefore the goods) remain with the buyer's bank, and the seller must deal with the consequence. D/Cs are appropriate for established relationships with trusted buyers but not for first transactions with new counterparties.
"Documentary letters of credit transfer payment risk from the buyer to their bank. For UK exporters entering new markets, this is not optional - it is standard commercial prudence."

Practical administration of trade instruments
UK businesses using LCs for the first time frequently underestimate the precision required in document preparation. A single discrepancy between the LC terms and the documents presented (a date format difference, a description mismatch, a quantity stated differently) constitutes a discrepancy that can delay or block payment. Most LC discrepancies are technical rather than substantive, but they still require resolution.
Working with a trade finance specialist at your bank or through a trade finance broker ensures that LC terms are reviewed before acceptance and that document preparation meets the requirements precisely. The cost of professional guidance is trivial compared with the cost of a payment delay or dispute on a large international transaction.

Frequently Asked Questions
How much does a letter of credit cost in the UK?
LC costs include issuance fees (typically 0.5-1.5% of LC value), advising and confirmation fees, and document handling fees. Total costs for a standard LC are usually 1-3% of the transaction value.
What is a confirmed letter of credit?
A confirmed LC adds the UK exporter's bank's guarantee to that of the issuing bank. If the issuing bank fails to pay, the confirming bank is obligated to pay. Confirmation is used for higher-risk country transactions.
What documents are typically required under a letter of credit?
Most LCs require: commercial invoice, full set of clean shipped bills of lading, packing list, and certificate of origin. Additional documents (inspection certificates, phytosanitary certificates, quality certificates) are common in specific sectors.
