Purchase order financing solves a specific problem: a business has a confirmed customer order it can't afford to fulfill. The PO funder pays the supplier directly (or issues a letter of credit), the goods ship to the customer, the customer pays, and the funder is repaid out of the proceeds. It's most common in import/export, wholesale, and contract manufacturing.
How a typical transaction flows
The borrower presents the PO funder with a customer purchase order, a supplier quote, and supporting documents. The funder evaluates the customer's credit, the supplier's reliability, and the gross margin on the deal. If approved, the funder pays the supplier directly — usually 70%–100% of supplier cost — and may issue a letter of credit if the supplier requires one.
Once goods ship and the customer is invoiced, the receivable is typically transitioned to a factor or paid directly into a controlled account that the PO funder uses for repayment.
What the funder is really underwriting
The customer's credit matters more than the borrower's. The funder is taking the risk that the end customer pays. Strong customers (Fortune 500, well-known retailers, government agencies) are easier to fund than long-tail customers.
Gross margin matters too. Most PO funders want at least 20%–25% gross margin on the deal — below that, the fee structure consumes too much of the profit.
Cost
PO financing fees are typically quoted as a percentage of the supplier cost per 30 days outstanding (commonly 1.5%–6% per month). The shorter the production-to-payment cycle, the cheaper the financing in absolute terms.
Where PO financing doesn't fit
It rarely fits service businesses (no goods to fund), low-margin commodity transactions, or orders with weak customers. It also doesn't fit borrowers who need general working capital — PO financing is transaction-specific.
