A customer just sent you the biggest order you have ever had. That is great news, until you look at the supplier's bill. You need to pay for the goods before you ship them, and your customer will not pay you until they arrive. If you are wondering how to fill a big order without the cash, purchase order financing is one option to know about. This guide explains it in plain words, step by step, and shows what to compare before you decide.
What is purchase order financing, in plain words?
Purchase order financing is funding that helps you pay your supplier so you can fill a large order from a customer. A "purchase order" is the written order your customer sends you. The funding is repaid when your customer pays you.
Think of it as a bridge. On one side is the order you want to say yes to. On the other side is the day your customer pays. The financing covers the gap in the middle.
How does purchase order financing work, step by step?
Here is the usual order of events. Details differ from one provider to another.
- Your customer sends a purchase order. It says what they want, how many, the price and when.
- You tell a financing provider about the order. You share the order, your supplier's quote and a little about your business.
- The provider checks the pieces. They usually look at how reliable your customer is, whether your supplier can deliver, and whether the order leaves enough room after costs.
- The provider pays your supplier. In many cases the money goes straight to the supplier, not to you.
- Your supplier makes or ships the goods, and they are delivered to your customer.
- Your customer pays. The provider is repaid first, along with its charges, and the rest comes to you.
Because the order is the focus, your own track record often matters less than how strong the customer and the order are. That does not mean everyone is approved. Nobody can promise that before looking at the details.

Example only: A small business sells custom winter gear. A large retailer sends an order that is much bigger than the owner has ever handled. The factory wants payment before it starts, and the retailer pays only after delivery. With purchase order financing, a provider pays the factory. The goods ship, the retailer pays, the provider is repaid, and the owner keeps what is left after costs. Your situation will be different.
Who is purchase order financing for?
It often suits businesses that buy products from someone else and sell them on, or have goods made for them. For example:
- Resellers and distributors who buy stock for a big customer
- Importers who pay overseas suppliers up front
- Small makers who need materials for a large run
- Wholesalers who win a larger contract than usual
It may not suit you if the order has thin room for profit after costs, if the work is mostly services instead of goods, or if the customer is new and untested. In those cases, the cost may be bigger than the benefit.
What do providers usually look at?
Every provider is different, but these are common things:
- The customer. Are they established and likely to pay on time?
- The supplier. Can they deliver the right goods when promised?
- The order itself. Is there enough left over after paying everyone?
- Your business. How long have you been operating, and have you filled orders before?
- The paperwork. A clear purchase order and a written quote from your supplier help a lot.

What does it cost, and what should I compare?
We cannot give you a number, because costs change from provider to provider and over time. What we can tell you is how to compare:
- The total you will repay, not just one headline number
- How long the money is outstanding. The longer it takes your customer to pay, the more it may cost
- Every fee, written down
- What happens if the customer pays late or the order changes
- Who deals with your customer, and how they are contacted
Our guides on APR vs. interest rate vs. fees and comparing business loan offers show how to do this step by step.
How is it different from invoice financing?
The two are cousins, but they work at different moments.
- Purchase order financing helps you pay for goods before you deliver them.
- Invoice financing helps you get cash after you have delivered and sent the bill, while you wait to be paid.
Some businesses use both, one after the other. Read our guide on invoice financing vs. factoring to see how the second step works. You can also look at asset-based financing, which uses things like unpaid invoices and stock.
What other options could help fill a big order?
Purchase order financing is not the only way. You might also consider:
- A business line of credit that you can draw from when an order arrives. See how it works.
- A working capital loan for the cost of the order. See working capital financing.
- A deposit from your customer. Even a partial payment up front reduces how much you need.
- Better payment terms from your supplier. Many will give more time to a good customer who asks.
- Splitting the order into smaller shipments.
The right choice depends on your situation. Talking it through often shows an option you had not thought of.
Common mistakes to avoid
- Saying yes to an order before you know how you will pay for it.
- Ignoring the cost of waiting. The longer your customer takes to pay, the more it may cost.
- Skipping a written quote from your supplier.
- Not checking your customer is likely to pay.
- Comparing only one number instead of the total you will repay.
- Taking the first offer when you could compare a few.
