Letters of Credit vs Trade Finance for Australian Importers
Guide information. Written by Ben. Published: 8 June 2026. Reviewed: 8 June 2026.
Letters of credit and trade finance both help Australian importers manage supplier payments, shipment timing, and working capital pressure, but they solve different problems. A letter of credit is mainly a bank-backed payment undertaking used to give an overseas supplier confidence that payment will be made if agreed documents are presented. Trade finance is the broader funding category that may include import loans, purchase order finance, supplier payment facilities, receivables finance, and working capital support.
The practical difference is simple: a letter of credit manages payment risk between buyer and seller, while trade finance usually manages cash-flow timing for the importing business. Many importers need both risk control and funding, but the right structure depends on supplier trust, documentation, shipment stage, inventory cycle, and the borrower's repayment pathway.
For business owners comparing import funding options, Emet Capital usually starts with the commercial question: are you trying to reassure the supplier, pay the supplier, fund the goods in transit, or bridge the gap until customers pay you?

Who This Is For
This guide is for Australian importers, wholesalers, manufacturers, distributors, and business owners comparing payment instruments with finance facilities. It is especially relevant when an overseas supplier wants payment certainty, a customer order is profitable but cash is tied up, or inventory will not convert to cash until weeks after shipment.
It is not a replacement for legal, tax, customs, or foreign exchange advice. Import transactions can involve contract law, Incoterms, marine insurance, currency exposure, and customs obligations. This article explains the commercial finance side only.
What Is a Letter of Credit?
A letter of credit is a payment instrument where a bank undertakes to pay a seller if the seller presents documents that match the letter of credit terms. In import trade, the Australian buyer's bank may issue the letter of credit in favour of the overseas supplier.
The supplier is not relying only on the buyer's promise to pay. The supplier is relying on the issuing bank's conditional undertaking. That can be valuable where the supplier does not know the buyer, the shipment value is large, or the supplier wants documentary control before releasing goods.
A letter of credit does not automatically mean the importer has solved its working-capital problem. The buyer may still need to fund the bank line, collateral, margin, fees, import GST, freight, customs duty, storage, and the period before customers pay.
What Is Trade Finance?
Trade finance is a broader category of business funding used to support the movement, purchase, sale, or conversion of goods. For importers, it may help fund supplier deposits, balance payments, goods in transit, landed inventory, or receivables after the goods are sold.
Trade finance can sit alongside working capital loans, invoice finance, debtor and supply chain finance, and sometimes private lending when the borrower needs a more flexible structure.
The lender is usually looking at the full trading cycle: who ordered the goods, who supplies them, when title moves, where the goods are, how they are insured, who will buy them, and when cash comes back in.
When To Use a Letter of Credit
A letter of credit is most useful when payment confidence and documentary control are the main issues. It can help when a supplier wants proof that a bank will pay if compliant documents are provided, or when the importer wants shipment documents controlled before payment is released.
Common situations include:
- first transactions with a new overseas supplier
- high-value shipments where trust is still developing
- suppliers in jurisdictions where payment enforcement is difficult
- goods that require strict shipping, inspection, or insurance documents
- transactions where the supplier will not release goods on open account terms
The key is precision. A letter of credit can protect both sides, but it can also create friction if documents do not match exactly. Even small wording differences can delay payment or require amendments.
When To Use Trade Finance
Trade finance is usually more relevant when the importer needs capital to complete the transaction. The business may have orders, customers, and profit margin, but cash is trapped in the gap between paying the supplier and being paid by customers.
Trade finance may fit when:
- a supplier deposit is due before customer revenue arrives
- the importer must pay a balance before shipment release
- goods are in transit for weeks before sale
- inventory has landed but customer invoices are not yet paid
- seasonal stock builds are straining cash flow
- a business wants to preserve cash while funding repeat import cycles
For businesses with confirmed customer demand, purchase order finance vs trade finance is often the next comparison. Where the pressure comes after delivery, invoice finance may be more relevant than funding the supplier stage.
Letter of Credit vs Trade Finance: The Core Difference
The core difference is that a letter of credit is a payment assurance tool, while trade finance is a funding tool. A letter of credit says, in effect, that payment will be made if documentary conditions are met. Trade finance says the business has capital available to fund part of the trade cycle.
This distinction matters because importers sometimes ask for a letter of credit when the real problem is working capital. If the supplier already trusts the importer but wants earlier payment, a finance facility may solve more than a documentary payment instrument. If the importer has cash but the supplier needs a bank undertaking, a letter of credit may be cleaner.
In practice, the best solution may combine both. A bank or financier may issue or support a letter of credit, then provide post-import or inventory funding once the goods are shipped or landed.
Documentation Lenders Usually Want
Strong files explain the trade cycle without forcing the lender to guess. For a letter of credit, the required documents usually focus on the contract and shipping terms. For trade finance, the file also needs to show repayment logic.
Useful documents include:
- supplier invoices and purchase contracts
- customer purchase orders or sales contracts
- bills of lading, airway bills, packing lists, and insurance certificates
- customs broker information and landed-cost estimates
- bank statements, management accounts, and aged receivables
- evidence of repeat trading history with supplier or customer
- details of currency, payment terms, shipment dates, and expected sale dates
If the importer also needs broader business funding, lenders may look at available security, including receivables, inventory, equipment, or property. That is where asset-backed lending can become relevant.
When Not To Use These Structures
Do not use a letter of credit or trade finance to hide an unprofitable trade cycle. If the imported goods have weak margin, uncertain demand, slow stock turnover, or unclear customer payment timing, finance may increase pressure rather than fix it.
A letter of credit may be poor fit where the transaction documents are likely to change repeatedly, the supplier is not familiar with documentary requirements, or the importer cannot tolerate delays caused by discrepancies.
Trade finance may be poor fit where there is no clear repayment source, the goods are speculative, the buyer base is uncertain, or the business is already using short-term facilities to cover long-term losses. In that scenario, business debt consolidation or a wider cash-flow review may be more appropriate than another import line.
Broker View: How To Choose the Right Structure
The cleanest choice starts with the bottleneck. If the supplier needs payment certainty, assess a letter of credit. If the business needs money to fund the supplier, freight, duty, inventory, or receivable gap, assess trade finance.
A broker can help compare lender appetite across banks, non-bank trade financiers, invoice finance providers, and private lenders. That comparison matters because lender fit varies by transaction size, product type, supplier location, customer quality, security, and how quickly the business needs funds.
For importers, the strongest applications show a profitable repeat cycle rather than a one-off scramble. The more clearly the file explains the purchase, shipment, sale, and repayment steps, the easier it is to match the transaction with the right facility.

FAQs
Is a letter of credit the same as trade finance?
No. A letter of credit is a conditional payment undertaking supported by a bank, while trade finance is a broader funding category that helps businesses pay suppliers, fund goods in transit, or bridge working-capital gaps.
Does a letter of credit give an importer cash?
Not directly. A letter of credit gives the supplier payment confidence if documents comply, but the importer may still need a facility, credit limit, collateral, or working-capital funding to support the transaction.
When is trade finance better than a letter of credit?
Trade finance is usually better when the core problem is cash-flow timing. If the importer needs capital to pay a supplier, land goods, hold inventory, or wait for customer payment, a funding facility may be more useful than a payment instrument alone.
Can an importer use both a letter of credit and trade finance?
Yes. Some import transactions use a letter of credit to manage supplier payment risk and a trade finance facility to fund the purchase, shipment, or post-import working-capital gap.
What documents matter most for import trade finance?
Lenders usually want supplier invoices, purchase orders, shipping documents, customer orders or invoices, insurance details, bank statements, and a clear repayment pathway showing how the facility will be cleared.
Is trade finance suitable for speculative stock purchases?
Trade finance is harder to justify when stock is speculative and there is no clear customer demand or repayment event. Lenders usually prefer transactions with identifiable buyers, repeat trading history, or strong evidence of stock turnover.
