Two solutions, one category: very different structures

Supply Chain Finance is not a single product. It is a category of solutions, each with distinct structures, risk profiles, economics, and use cases. Among the most commonly confused are Approved Payables Finance and Reverse Factoring.

Both involve a buyer-initiated program in which suppliers can receive early payment on approved invoices. Both involve a financial institution or third-party funder. And both use the buyer's commercial relationship as the foundation.

But the structural difference between them is significant, and it has major implications for financing cost, risk allocation, legal structure, and strategic use.

What is Approved Payables Finance?

Approved Payables Finance (APF) also called reverse factoring or confirming, though these terms are used loosely in the market, is the most common form of Supply Chain Finance. Its defining characteristic is the buyer's irrevocable and unconditional payment guarantee to the financial institution funding the program.

Under an APF structure:

The buyer approves supplier invoices and commits to pay the funder at maturity
The credit risk for the funder sits entirely on the buyer, not the supplier
Because the buyer is the credit risk, funders can offer suppliers low financing rates, often anchored to the buyer's investment-grade credit rating
Suppliers receive 100% of the invoice value (minus a small financing fee) when they elect early payment
Buyers improve DPO by extending payment terms, while suppliers can access liquidity without that DPO extension hurting them

APF programs are predominantly implemented by investment-grade multinational buyers, as their credit rating is what makes the low-cost financing possible. The typical annual financing rate for suppliers in APF programs is 1-4% APR, substantially lower than most alternative short-term funding sources.

What is Reverse Factoring?

Reverse Factoring, in the narrower, structural sense, is a simplified version of Approved Payables Finance. The key difference: the buyer does not provide an irrevocable payment guarantee to the funder.

Instead, the buyer introduces the financing service to its suppliers. Suppliers can view approved invoices through the platform and request early payment. But because there is no unconditional buyer payment commitment, the funder must assess both buyer and supplier risk, not just the buyer's.

Under a Reverse Factoring structure:

The buyer introduces the program but does not provide a legal payment guarantee
Credit risk sits on both the buyer's creditworthiness and the supplier's performance risk
Financing rates are higher, typically 5-15% APR, reflecting the additional risk
Easier to start: no legal commitment from the buyer means faster implementation and less regulatory scrutiny

Key differences at a glance

Approved Payables Finance vs. Reverse Factoring

Buyer commitment. Approved Payables Finance: Irrevocable payment guarantee. Reverse Factoring: Introduction only, no guarantee.
Credit risk on. Approved Payables Finance: Buyer only. Reverse Factoring: Buyer + supplier performance.
Cost to supplier (APR). Approved Payables Finance: 1-4%. Reverse Factoring: 5-15%.
Target buyers. Approved Payables Finance: Investment-grade, $1B+ revenue. Reverse Factoring: Investment and sub-investment grade.
Target suppliers. Approved Payables Finance: Strategic, high-volume. Reverse Factoring: Non-strategic, smaller volumes.
Time to implement. Approved Payables Finance: Long (legal complexity). Reverse Factoring: Medium.
Accounting treatment. Approved Payables Finance: Potential financial debt reclassification. Reverse Factoring: Generally off-balance sheet for suppliers.

The role of payment terms intelligence

The choice between APF and Reverse Factoring and the design of the program itself, should not be made in isolation. The most effective SCF programs are built on a foundation of payment terms intelligence: knowing where your current terms stand relative to the market, which supplier segments have the most to gain from early payment access, and what the optimal term structure looks like before the financing layer is designed.

Without this intelligence, even well-structured SCF programs may be optimizing the wrong variables.

Frequently Asked Questions

What is the difference between Approved Payables Finance and Reverse Factoring?

Approved Payables Finance involves a buyer providing an irrevocable, unconditional payment guarantee to a financial institution, meaning credit risk sits entirely on the buyer. Reverse Factoring does not include this guarantee, the buyer simply introduces the program to suppliers, but the funder still assesses both buyer and supplier risk. APF typically offers lower financing rates (1-4% APR vs 5-15% for reverse factoring) but requires more legal complexity and is limited to investment-grade buyers.

What is Approved Payables Finance?

Approved Payables Finance is the most common form of Supply Chain Finance. Under this structure, a buyer approves supplier invoices and commits to paying a financial institution at invoice maturity through an irrevocable payment undertaking. The supplier can then receive early payment from the financial institution at a rate reflecting the buyer's credit rating, typically 1-4% APR. Both buyer and supplier benefit: the buyer extends DPO, and the supplier accesses low-cost liquidity.
