Letters of credit, documentary collections and supply chain finance can unlock working capital and reduce payment risk. A practical guide to choosing the right tool for each trade.

By M&G Signature Advisory Team

For a growing business that trades internationally, cash is usually the constraint. Suppliers want paying before goods ship. Customers want to pay after goods arrive. In between sit weeks of shipping, customs and inspection. Trade finance exists to bridge that gap and to manage the risk that one side does not perform.

The core tools

Letters of credit

A letter of credit is a bank's undertaking to pay the seller, provided the seller presents documents that match the terms of the credit. Most are issued under the ICC's UCP 600 rules. For the seller, it replaces the buyer's credit risk with a bank's. For the buyer, it means payment only happens against the agreed documents.

Letters of credit are most useful with new trading partners, in higher-risk markets and for large orders. They do carry cost and paperwork, and a discrepancy in the documents can delay payment. Precision in drafting and presentation matters.

Documentary collections

In a documentary collection, banks handle the shipping documents but do not guarantee payment. The buyer receives the documents, and with them control of the goods, only when they pay or accept a bill of exchange. Collections are cheaper and simpler than letters of credit and suit established relationships where some security is still wanted.

Supply chain finance

Supply chain finance lets suppliers be paid early, usually at a discount based on the buyer's credit rather than their own, while the buyer keeps longer payment terms. It can strengthen a supply base and free up working capital on both sides, but it needs a buyer with enough scale and credit standing to support a programme.

Invoice and inventory finance

Receivables finance releases cash against unpaid invoices. Inventory and pre-shipment finance fund stock and production. Both can be useful for businesses that are growing faster than their cash flow.

Export credit support

The UK's export credit agency, UK Export Finance, can provide guarantees and insurance that help exporters secure finance and protect against non-payment. Many businesses do not realise they are eligible.

Banking relationships

Trade finance depends on banks that understand your corridors. A bank that is strong in European trade may have little appetite for Asian or African flows. Businesses that trade across several regions often need more than one banking relationship, and they need those relationships in place before a large order arrives, not after.

The shift to digital documents

Trade has always run on paper: bills of lading, invoices and certificates moving by courier. That is changing. In England and Wales, the Electronic Trade Documents Act 2023 gave electronic trade documents the same legal standing as paper ones, provided they meet the Act's requirements. As banks, carriers and platforms adopt digital documents, presentation is becoming faster and less prone to error.

Common mistakes

  • Choosing on price alone. The cheapest instrument is not always the safest for a particular trade.
  • Poor document discipline. Most delays come from documents that do not match the terms exactly.
  • Ignoring currency risk. A well-financed trade can still lose money if exchange rates move. Hedge known exposures.
  • Leaving it too late. Facilities take time to set up. Arrange them before the order, not when the supplier demands payment.

The bottom line

Trade finance is not only for large corporates. Used well, it lets growing businesses take on bigger orders, trade with new partners and protect their cash. The key is matching the tool to the trade, and building the banking relationships before they are needed.
