Purchase Order Finance UK 2026
Market Invoice is an independent UK invoice finance comparison site that ranks 89 UK invoice finance providers.
Purchase Order (PO) finance lets UK businesses fund supplier costs against a confirmed customer purchase order, before goods are delivered or an invoice is raised. The lender pays the supplier directly (or via a back-to-back letter of credit), the goods are delivered to the customer, the customer pays the invoice, and the lender takes its principal plus 2 to 5 percent fee. Used by importers, manufacturers and distributors who win large orders that exceed working capital. UK specialists include Optimum Finance, Nucleus, Time Finance and Stenn (export-only). Often combined with invoice finance to cover the entire order-to-cash cycle.
