Supply Chain Finance: Unlocking Working Capital Across the Chain

The tension between buyer and supplier over payment terms is as old as commerce itself. Buyers want to pay as late as possible to preserve their own working capital. Suppliers want to be paid as early as possible for the same reason. Traditional negotiation produces a number somewhere in the middle — net-30, net-60, net-90 — and one party is always less satisfied than the other. Supply chain finance (SCF) is a family of instruments designed to resolve this tension by bringing a third party — typically a bank or specialist SCF provider — into the payment relationship. Used correctly, SCF creates genuine value: the buyer gets the extended terms it wants, and the supplier gets early payment it would not otherwise have access to. Used poorly, SCF conceals liquidity problems, creates dangerous supplier concentration, and generates off-balance-sheet financing that surprises auditors and analysts alike.

The main instruments

1. Dynamic discounting. The buyer offers to pay invoices early in exchange for a discount. The earlier the payment, the larger the discount offered. Crucially, the buyer is using its own cash — no external financing party is involved. This makes dynamic discounting suitable for buyers with strong liquidity who can effectively deploy idle cash at rates better than money market returns. For suppliers, dynamic discounting offers flexible early payment at rates that are typically lower than their own cost of borrowing. The main limitation is that the programme is only available when the buyer has surplus cash to deploy.

2. Reverse factoring (approved payables finance). In reverse factoring, the buyer approves supplier invoices and a bank or SCF provider then pays the supplier early — at a rate based on the buyer's credit rating rather than the supplier's. Because large buyers typically have stronger credit ratings than their suppliers, the financing rate available through the buyer's SCF programme is lower than what the supplier could obtain independently. The buyer repays the financing party on the original due date, effectively extending days payable outstanding (DPO) without the supplier bearing the cost of that extension. Reverse factoring is the most widely used SCF instrument and the one most frequently in the financial news — often for the wrong reasons.

3. Inventory finance. A financing party advances funds against inventory that is in transit or held in warehouse — allowing the buyer to take delivery without immediate payment or the supplier to manufacture without waiting for a purchase order advance. Inventory finance is particularly relevant in industries with long lead times and high working capital requirements: automotive, apparel, electronics, and commodities.

4. Purchase order finance. Financing against a confirmed purchase order, before the goods are manufactured or shipped. PO finance allows suppliers with limited working capital to fulfil large orders they could not otherwise fund. It is most commonly used by smaller suppliers serving large retailers or manufacturers.

How SCF benefits both parties — and the systemic risk

The commercial logic of reverse factoring is genuinely attractive. A large retailer with a strong credit rating can arrange SCF financing at rates that would be unavailable to a small manufacturer. The manufacturer gets access to low-cost early payment; the retailer extends its DPO and frees up working capital. Neither party is materially worse off, and in aggregate, working capital in the supply chain is reduced. The problem is dependency. If a supplier becomes reliant on one buyer's SCF programme as a core source of operating liquidity, the programme is effectively a credit facility disguised as a payment mechanism. If the buyer withdraws the programme, reduces the credit limit, or experiences a downgrade that increases the financing cost, the supplier may face a sudden liquidity crisis that has nothing to do with its own operational performance. The 2021 collapse of Greensill Capital — a major SCF provider — illustrated how fragile this dependency can become when it is embedded at scale across a supply chain.

When SCF is appropriate — and when it is not

Supply chain finance is appropriate when it genuinely benefits both parties: when the supplier has a higher cost of capital than the buyer, when the supplier values early payment certainty, and when the buyer has payment terms that are sustainable in the relationship. It becomes problematic when it is used to extend payment terms beyond what the commercial relationship would otherwise support — essentially financing the buyer's working capital position at the supplier's expense through a mechanism that is less transparent than a direct credit facility. A more direct intervention — shortening payment terms to a commercially fair level and compensating for that in negotiated pricing — is often more honest and more durable than complex SCF arrangements that obscure the underlying cash flow dynamic. SCF is a tool, not a substitute for fair commercial terms.
