Purchase Order Finance: Funding Sales Before Delivery

Purchase order (PO) finance advances capital against confirmed customer orders before the goods are manufactured, imported, or delivered. It solves a different problem from invoice finance: where invoice finance releases cash tied in invoices already raised, PO finance funds the production or procurement necessary to fulfil an order in the first place. For UK product businesses with significant upfront costs relative to order value, PO finance can be the difference between being able to accept a large order and having to turn it down.

How purchase order finance works
The mechanics are straightforward. You receive a confirmed purchase order from a creditworthy customer. The PO finance provider verifies the order and advances funds, typically direct to your supplier, to fund the production or procurement. When you deliver and invoice the customer, an invoice finance facility repays the PO finance provider from the proceeds. The cost is the PO finance fee plus the invoice finance fee covering the combined period.
Because PO finance bridges two funding stages - production and payment - it is inherently more expensive than invoice finance alone. Cost typically runs at 2-4% per month on the advanced amount, reflecting the higher risk relative to a completed, invoiced transaction. This cost needs to be factored into contract pricing or margins to ensure the order remains profitable after financing.
Which UK businesses benefit most
PO finance suits UK businesses that: have confirmed orders from creditworthy buyers, have suppliers who will accept payment from a finance provider, operate in a sector where goods can be clearly identified and valued, and have margins sufficient to absorb the finance cost. Importers, manufacturers, and distributors in consumer goods, electronics, industrial products, and food are among the most common users.
The key qualifying factor is the creditworthiness of the end customer: PO finance lenders are advancing against the order, so the customer's ability and willingness to pay is central to their assessment. Orders from FTSE 350 companies, government bodies, and established retailers attract the most competitive terms. Orders from new or smaller buyers are harder to finance and more expensive.
"Purchase order finance turns a confirmed order from a promise into working capital - enabling UK businesses to say yes to contracts they would otherwise have to decline."

PO finance vs other short-term working capital tools
The main alternative to PO finance for order funding is an unsecured business loan or revolving credit facility used to fund production. For small orders, this is often simpler and cheaper. For large orders relative to the business's size, a loan facility may not provide enough capital, and the mismatch between drawing capital speculatively and funding against a specific confirmed order becomes relevant.
Some businesses use a combination of PO finance for specific large orders alongside a general working capital facility for smaller orders. This hybrid approach maximises capital efficiency: using the most appropriate and cost-effective tool for each situation rather than a one-size-fits-all approach.

Frequently Asked Questions
What is the minimum order size for purchase order finance in the UK?
Most PO finance providers require a minimum order value of £50,000-£100,000. Below this, a business loan or revolving credit is typically more practical.
Does my customer need to know I am using PO finance?
Often yes, because the finance provider may pay your supplier directly and need to notify your customer of the assignment of the receivable. This is a standard commercial arrangement and should not concern creditworthy buyers.
Can I use PO finance for both domestic and overseas orders?
Yes, though the structure differs. Domestic PO finance is simpler. International PO finance often involves letters of credit to manage supplier payment risk alongside the advance.
