What is the difference, in one sentence?
Where the cash gap sits. Purchase order financing funds the period before delivery, when the supplier wants paying and nothing has shipped. Factoring funds the period after the invoice is raised, when the goods have gone and the customer has terms. Same order, two different gaps, separated by the delivery.
That distinction settles most of the confusion, because it converts a product question into a timing question the business can answer without help. If the money is needed to pay a supplier so that goods can be made or bought, no invoice exists yet and factoring has nothing to buy. If the goods have shipped and an invoice is outstanding, the supplier has already been paid and purchase order financing has nothing left to fund.
The consequence people miss is that these are not competing answers to one question. They are consecutive answers to two, and a business filling a large order with thin working capital often meets both gaps on the same transaction, five or six weeks apart.
| Purchase order financing | Invoice factoring | |
|---|---|---|
| What it funds | Paying the supplier so the order can be filled | The wait between invoice and customer payment |
| When in the cycle | Before delivery | After the invoice is raised |
| What it is advanced against | A confirmed purchase order and the supplier invoice | An invoice a customer already owes |
| Advance rate | 70% to 90% of supplier invoice, up to 100% for stronger profiles; 80% to 90% of order value on one funder's terms | 95% on one publisher's comparison |
| Published cost | 1% to 6% per 30 days, 20% to 80% annualized | 1% to 5% per 30 days, 20% to 70% annualized |
| What repays it | The factoring or receivables proceeds once the order is delivered | The customer's payment |
Why is almost every comparison written by a factor?
Because factoring is the larger and older market, and its providers publish more. Search the comparison directly and the ranked results are, with few exceptions, pages published by companies that sell one of the two products, plus an education publisher that monetizes through lender referrals (FitSmallBusiness, Lauren McKinley, reviewed by Tricia Jones, updated 20 May 2025).
This is worth naming without making it an accusation. Those pages are not dishonest; the strongest of them publish their own rates and annualize them plainly, which is more than several markets further up the capital stack manage. But a comparison written by a seller of one product resolves toward that product by construction, and a comparison whose honest answer is sometimes neither is not one any single-product provider can publish.
The neutral version of the answer is short enough to state here in full. Before delivery, purchase order financing. After the invoice, factoring. Recurring rather than occasional, and with a fundable balance sheet behind it, an asset-based facility instead of either, because transaction pricing paid indefinitely is the most expensive mistake available in this part of the market.
“A business asking which of the two it needs is usually describing the gap without realizing it. Whether the goods have shipped decides the answer, and it decides it before anyone gets to price.”
What does each cost, and why does the headline comparison mislead?
They price within sight of each other and are used for different lengths of time. On one publisher's side-by-side, purchase order financing runs 1% to 6% per 30 days for an annualized 20% to 80%, and invoice factoring runs 1% to 5% per 30 days for an annualized 20% to 70% (FitSmallBusiness, updated 20 May 2025). Purchase order funders' own published ranges sit inside that: 1.8% to 6% per month, annualizing to 30% to 80% and above on one funder's page and 20% to 75% on another's (Crestmont Capital, Allan Garfinkle, 31 March 2026; Drip Capital, Romina Mohan Gopalan, 25 April 2026).
The annualized figures invite a comparison the products do not support. Purchase order funding is typically outstanding for a trade cycle of 30 to 90 days, averaging around 45 (Drip Capital, 25 April 2026), while a factoring line is a standing arrangement against a rolling receivables book. Comparing an annualized rate on a one-off six-week exposure with an annualized rate on a permanent facility is comparing two numbers that were built to answer different questions.
The advance rates differ in a way that matters more than the fee. Factoring advances against an invoice a customer already owes, so the advance runs high, quoted at 95% on that publisher's comparison. Purchase order financing advances against goods that do not exist yet, at 70% to 90% of supplier invoice value with up to 100% for stronger profiles on one funder's terms and 80% to 90% of order value on another's. Anything below 100% is working capital the business still has to find, which is precisely the thing it did not have.
How do the two work together on one order?
In sequence, with the second repaying the first. The purchase order line pays the supplier and funds production; once the order is delivered and the customer is invoiced, that line is closed and repaid out of the proceeds of the factoring line, which then carries the receivable until the customer pays (Commercial Capital LLC, Marco Terry, accessed 6 September 2026).
The reason to run both rather than one is cost, not convenience. Purchase order financing is the more expensive of the two, and the point of handing the exposure to a factor at delivery is to stop paying transaction pricing for the waiting period. One funder states the objective plainly: use purchase order financing for as short a period as possible (same source).
The mechanics of running two funders against one transaction come down to one document. Where a purchase order line sits alongside a factoring or asset-based facility, both lenders sign an inter-creditor agreement setting out who has what and in which order, and providers in this market execute those routinely (Commercial Capital LLC, accessed 6 September 2026). A borrower who discovers the requirement during documentation rather than during selection loses the days it was financing to buy.
Which one does your business actually need?
Answer three questions in order and the product falls out. Have the goods shipped? If not, the gap is before delivery and only purchase order financing addresses it. Is there an invoice a creditworthy customer owes? If so, factoring is the cheaper and simpler instrument for that half. Does this happen once a quarter or every month?
That third question is the one the comparison pages rarely ask, and it changes the answer rather than refining it. A genuine spike, an order materially larger than anything the business normally fills, is what transaction financing is for. A pattern of orders the business cannot fund from its own working capital is not a spike; it is a structural working capital shortfall being financed at transaction prices, and it usually belongs in a facility rather than in a series of deals.
The check that follows is whether the balance sheet can support one. A business with real receivables and real inventory has an asset-based option that prices far inside either product here, at the cost of more administration and a slower start. A business without those assets does not, at any price, which is what keeps transaction financing legitimate for the companies that genuinely need it. Where the graduation point sits, and what it costs to cross, is the subject of the companion piece on when to stop using purchase order financing.
