Supply Chain Finance: How It Works, How It Differs From Reverse Factoring, and When to Use It

Supply chain finance is a buyer-led program in which a bank or other funder pays a buyer's approved supplier invoices early at a discount. The buyer then pays the funder on the original due date or later.

It works because the funder prices the deal on the buyer's credit rather than the supplier's. That's also why it carries risks the buyer owns, from rating-agency scrutiny to disclosure rules. You'll also hear it called supplier finance, payables finance, or reverse factoring.

Key Takeaways

• Supply chain finance (SCF) lets suppliers get paid early by a funder, priced on the buyer's credit, while the buyer pays on its normal terms.

• Reverse factoring is the payables-finance technique at the heart of buyer-led SCF. Ordinary invoice factoring is started by the supplier.

• In SCF a funder's money pays the supplier early, while discounting programs use the buyer's own cash.

• Since 2023, U.S. GAAP has required buyers to disclose the main details of supplier finance programs.

• For much of a mid-market supplier base, paying by virtual card is a simpler working-capital lever than a bank-funded program.

What is supply chain finance?

Supply chain finance is a set of techniques that let suppliers receive early payment on invoices a buyer has approved, funded by a third party and priced on the buyer's credit risk. Meanwhile the buyer keeps its payment terms, and the supplier gets cash sooner at a lower cost than it could usually borrow on its own.

The Global Supply Chain Finance Forum's Standard Definitions for Techniques of Supply Chain Finance calls the buyer-led version "payables finance." It lists reverse factoring and supplier finance among the market's synonyms, and it describes the arrangement as led by the buyer and priced on the buyer's credit.

It's a large market. The Secured Finance Network's 2025 Supply Chain Finance Market Sizing Study estimated the U.S. supply chain finance market at about $2.56 trillion in 2024. That figure is a modeled estimate, but it shows how much supplier payment now runs through financing arrangements of some kind.

How does supply chain finance work, step by step?

Supply chain finance follows a predictable sequence once the program is in place:

1. The buyer sets up a program with a bank or other funder and invites selected suppliers to join.

2. Next, the supplier delivers and invoices as usual, and the buyer approves the invoice for payment on its due date.

3. Approved invoices appear on the program's platform, where the supplier can choose to be paid early.

4. If the supplier opts in, the funder pays the invoice amount minus a discount for the days remaining until the due date.

5. On the due date, the buyer pays the full invoice amount to the funder instead of the supplier.

Everything hinges on the buyer's approval. Once the buyer confirms it will pay the invoice, the funder is lending against the buyer's promise, not the supplier's balance sheet.

Who pays for supply chain finance?

The supplier usually pays, through the discount it accepts when it takes early payment. Because the discount reflects the buyer's credit, it's often cheaper than the supplier's own borrowing. The gap tends to be widest for smaller suppliers selling to a large buyer with a strong rating.

The buyer's gain is different. It can hold its standard business payment terms, or extend them, without squeezing suppliers who need cash sooner. That supports a higher days payable outstanding without straining supplier relationships. Programs may also carry platform or administration costs, depending on how the funder and buyer structure them.

Picture a supplier holding a $200,000 approved invoice due in 90 days. Rather than wait three months, it takes early payment through the buyer's program and receives the invoice amount minus a discount set by the funder. The buyer still pays $200,000, just to the funder on day 90. Whether the trade is worth it depends on what the supplier would otherwise pay to borrow, and on what it could do with the cash in the meantime. These figures are illustrative only.

Is supply chain finance the same as reverse factoring?

In common use, yes. Reverse factoring is the payables-finance technique at the center of buyer-led supply chain finance, and the Global SCF Forum treats the two names as synonyms for the same arrangement.

The "reverse" refers to who starts it. In reverse factoring, the buyer sets up the program and brings its suppliers in. In ordinary invoice factoring, a supplier sells its own receivables to a factor to raise cash, often without the customer's involvement. The factor then prices the deal on the supplier's business and the credit quality of the customers it invoices.

Is supply chain finance the same as factoring?

No. Factoring is seller-initiated and priced on the supplier's receivables, while supply chain finance is buyer-initiated and priced on the buyer's credit. A supplier can use factoring with any customer. It can only use supply chain finance when a buyer offers a program and approves the invoice.

That difference shows up in cost. A small supplier factoring its invoices pays a rate that reflects its own risk. The same supplier in a strong buyer's program borrows, in effect, at a rate closer to the buyer's.

How does supply chain finance compare with dynamic discounting and card payments?

All four of these options get suppliers paid sooner, but they differ in who starts them, whose money funds them, and who bears the cost. The table below sets them side by side.

The card interchange figures come from Visa's USA Interchange Reimbursement Fees schedule. Dynamic discounting and early payment discounts use the buyer's spare cash to capture a discount, so they suit buyers with more liquidity than they need.

Each lever fits a different part of the supplier base. Supply chain finance tends to fit large buyers with strong credit and a set of large strategic suppliers, because the setup and onboarding effort is real. Early payment discounting fits buyers sitting on cash that earns little. Virtual card payment fits the broad middle of the supplier base that already accepts cards. A card program can improve cash flow for the buyer while getting suppliers paid promptly. Corpay's single-use virtual cards fit that role, since each card number is issued for one supplier payment.

What are the risks of supply chain finance?

The main risks are dependence on a single funder, scrutiny from rating agencies and investors, and suppliers who come to rely on early payment that could disappear. A buyer that runs a program owns those risks, even though a funder supplies the money.

Funder concentration became a public lesson with the collapse of Greensill Capital, a supply chain finance provider. The UK House of Commons Treasury Committee published its report, Lessons from Greensill Capital, on July 20, 2021. When a funder exits, suppliers who counted on early payment can face a sudden cash gap, and the buyer may have to pay on its longer terms without the financing in place.

Rating agencies have raised concerns for years. Moody's warned in 2019 that reverse factoring can hide debt-like obligations from investors, as reported by CFO Dive. Fitch said in 2018 that reverse factoring could raise a company's vulnerability to default, according to Global Trade Review, which also reported industry pushback on Fitch's call to treat SCF as debt.

Suppliers face their own risks. Some useful questions for a supplier deciding whether to join a buyer's program:

• What happens to early payment if the funder leaves the program?

• Can the buyer extend terms again once you're enrolled?

• How is the discount set, and how often can it change?

• Does joining the program affect your other financing arrangements?

Does supply chain finance count as debt?

Under U.S. GAAP, supply chain finance doesn't change how the buyer recognizes or measures the payable, but it does require disclosure. The FASB's ASU 2022-04, Liabilities: Supplier Finance Programs (Subtopic 405-50), sets out what buyers must report.

Buyers must disclose:

• The program's main terms.

• The confirmed amount outstanding at the end of the period.

• Where those obligations sit on the balance sheet.

• A roll-forward of the obligations during the period.

The disclosures apply for fiscal years beginning after December 15, 2022, and the roll-forward for fiscal years beginning after December 15, 2023. Rating agencies may still adjust their own view of debt, and terms that stretch well past normal practice can draw questions. Confirm the treatment of any specific program with your auditor.

How do you set up a supply chain finance program?

Setting up a supply chain finance program means choosing a funder, deciding which suppliers qualify, setting a terms policy, and building the onboarding, integration, and disclosure processes around it. Treasury, AP, procurement, and accounting all have a role.

A practical sequence looks like this:

1. Choose a funder or platform and agree on pricing, limits, and how either side can exit.

2. Define eligible suppliers, usually by spend, strategic importance, and need for liquidity.

3. Set a payment-terms policy, including whether and how far terms will extend.

4. Plan supplier enablement, with clear communication on how the program works and what it costs suppliers.

5. Connect invoice approval in your ERP to the program platform, so approved invoices flow through without manual steps.

6. Build the ASU 2022-04 disclosure process with your accounting team and auditor before the first period-end.

Start small if you can. Many buyers pilot a program with a handful of large suppliers, learn how onboarding and approvals behave in practice, and widen eligibility once the process runs cleanly. A pilot also gives the accounting team a quiet period to rehearse the disclosure work before the program grows.

Fast, reliable invoice approval matters more than it seems. Suppliers can only take early payment on approved invoices, so a slow approval process limits the program's value. That's the same reason AP automation helps cash flow across the board. Corpay's ERP integrations include NetSuite and Sage Intacct, so invoices approved in the ERP move to payment without manual steps.

Pay suppliers faster and hold cash longer with Corpay virtual cards

For many mid-market buyers, paying suppliers by virtual card offers a simpler working-capital lever than a bank-funded program. Suppliers that accept cards get paid promptly, and the buyer settles with the issuer on the card's billing cycle.

Corpay virtual cards include single-use virtual cards. Each is issued for a specific payment, which tightens control over every transaction. Corpay clients earn $800M+ in rebates per year on card spend. With Corpay's fully managed AP, suppliers who don't take cards are paid by ACH or check from the same workflow, so one process covers the whole supplier base. That's a core part of the benefits of supplier payment automation.

Corpay payments automation connects through 100+ ERP integrations, including NetSuite, Sage Intacct, Business Central, and Acumatica. Teams save about 40% of the time they spend on AP processing, and most are live in weeks.

Frequently Asked Questions

What is supply chain finance in simple terms?

Supply chain finance lets a supplier get paid early on an invoice the buyer has approved. A bank or other funder pays the supplier, minus a small discount, and the buyer pays the funder on the original due date.

Is reverse factoring good for suppliers?

It can be. Reverse factoring gives suppliers early payment at a rate based on the buyer's credit, which is often cheaper than their own borrowing. The risks are that the program could end, or that the buyer uses it to push terms out further than the supplier would otherwise accept.

Is reverse factoring better than dynamic discounting?

Neither is better in every case. Reverse factoring suits buyers that want to keep or extend terms while suppliers get paid early with a funder's money. Discounting suits buyers with spare cash that want to earn a discount by paying early themselves.

Do companies have to disclose supply chain finance programs?

Yes, under U.S. GAAP. Since ASU 2022-04 took effect, buyers have disclosed a program's main terms, the confirmed amount outstanding, where it sits on the balance sheet, and, from the later effective date, a roll-forward of the obligations.
