Trade Finance Explained: Letters of Credit, PO Finance, and Supply Chain Finance
By Zolvo Team · 3 min read
Buying and selling goods, especially across borders, runs into two problems at once. The seller wants to be sure it will be paid before it ships; the buyer wants to be sure it will receive the goods before it pays; and in between, someone has to fund production and shipment while nobody has yet been paid. Trade finance is the set of tools that solve both problems, bridging the trust gap and the cash gap along the journey from order to cash. This guide explains the main tools and how they fit together.
The Problem Trade Finance Solves
Every trade has a timing mismatch. A supplier has to buy materials and produce goods before it can ship them, and then it waits, often 30, 60, or 90 days, to be paid. The buyer, meanwhile, does not want to release cash until it knows the goods are real and on their way. Left unmanaged, that mismatch either kills deals between parties who do not fully trust each other, or starves a growing business of the cash tied up in inventory and receivables. Trade finance provides the guarantees and the funding that let the trade happen anyway.
The Main Tools, Along the Order-to-Cash Cycle
The tools of trade finance line up with the stages of a transaction:
- Purchase order finance. Before goods ship, purchase order finance pays the supplier against a confirmed customer order, so a business can fulfill an order it could not otherwise afford to produce.
- Letter of credit. A letter of credit is a bank's guarantee that the seller will be paid once it presents compliant shipping documents, substituting the bank's credit for the buyer's and de-risking the payment.
- Supply chain finance. Supply chain finance lets suppliers get paid early on approved invoices, usually funded on the strength of the buyer's credit, smoothing cash flow across the chain.
- Factoring. After delivery, factoring monetizes the resulting invoice, advancing most of its value rather than waiting the full payment terms.
How They Fit Together
These tools are complementary, not competing. A single large order can move through several of them in sequence: purchase order finance pays the supplier so production can begin, a letter of credit secures payment on shipment, the goods are delivered and invoiced, and a factoring advance on that invoice repays the purchase order facility. Each tool addresses a different point in the cycle, the cost of producing, the risk of paying, and the wait to collect, and together they keep goods and cash moving when a single product could not.
Why Trade Finance Is Servicing-Intensive
Trade finance is document-heavy and multi-party, which makes it operationally demanding to service. A lender has to verify orders, suppliers, and end customers before funding, track each deal through fulfillment across counterparties, and reconcile the hand-offs as a purchase order becomes an invoice and an invoice becomes a payment. Done by hand, a stalled shipment or an unverified counterparty is easy to miss until it is a loss, which is why the discipline behind the paperwork matters as much as the structures themselves.
How Zolvo Fits
Zolvo automates the verification, monitoring, and reconciliation behind trade-finance lending on top of the systems a lender already runs. It verifies counterparties and documents before funding, tracks each deal through fulfillment, and reconciles the hand-off when a purchase order converts to a factored invoice, across purchase order finance, supply chain finance, and factoring as one connected operation.
