Supply Chain Finance (Reverse Factoring)

Cash flow is frequently cited as the primary reason SMEs decline to pursue public sector contracts they could otherwise win. Even where payment terms are technically 30 days, invoice processing delays, approval chains, and administrative backlogs mean that actual payment can take considerably longer. Supply chain finance, or reverse factoring, addresses this gap by allowing SMEs to access the value of an approved invoice before the contractual payment date, at a financing cost that reflects the buyer's creditworthiness rather than the SME's own balance sheet.

What is supply chain finance (reverse factoring)?

In a conventional factoring arrangement, a supplier sells its receivables (invoices) to a finance provider at a discount, receiving cash immediately. The finance provider then collects payment from the buyer. The financing cost is driven by the supplier's credit risk.

Reverse factoring inverts this structure. The buyer (in public procurement contexts, the contracting authority or the prime contractor) establishes a programme with a finance provider. When the buyer approves a supplier's invoice, the supplier can elect to receive early payment from the finance provider, at a discount that reflects the buyer's credit rating. Because large public sector buyers have excellent credit ratings, the financing cost is substantially lower than a small supplier could access on its own account. The buyer pays the finance provider at the contractual payment date.

In a public procurement context, supply chain finance programmes may be offered directly by contracting authorities (particularly large central government buyers), or by prime contractors who have their own SCF programmes and extend access to their subcontractors. The UK government has run a number of supply chain finance initiatives aimed at ensuring that SMEs in government supply chains benefit from the government's own credit rating rather than bearing the cost of their own risk.

Supply chain finance differs from payment within 30 days in that it is a financing product, not a legal obligation. The 30-day rule sets the floor for when the buyer must pay; supply chain finance allows the supplier to access that value earlier, at a cost. The two mechanisms are complementary: prompt payment reduces the frequency with which SMEs need to use supply chain finance, while supply chain finance provides a cost-effective bridge when cash is needed before the payment date arrives.

From a procurement policy perspective, supply chain finance is treated as a tool for supporting SME participation in large public contracts. A prime contractor that operates an SCF programme can credibly commit to its subcontractors that they will not face cash-flow crises while waiting for payment, which in turn makes the contract more attractive to smaller supply chain members.

Why it matters for bidders

For an SME considering a contract that requires significant upfront investment (materials, staff costs, subcontractors), the availability of supply chain finance on the main contract or on a prime contractor's SCF programme can be the difference between accepting and declining the opportunity. Before submitting a bid, suppliers should ask whether the contracting authority or prime contractor operates an SCF programme, what the financing rate is, and how quickly approved invoices can be funded.

For organisations in the local supply chain serving as second-tier subcontractors, access to SCF is often mediated through the prime contractor. Prime contractors who have made SCF access available to their supply chains as part of their community benefit or social value commitments may offer a meaningful financial advantage to smaller partners.

Example

A small mechanical engineering company in Austria wins a subcontract on a federal infrastructure project worth EUR 900,000 over 18 months. The prime contractor operates a supply chain finance programme through a major Austrian bank. The small company submits an invoice for EUR 180,000 for the first delivery milestone. Within 48 hours of the prime contractor approving the invoice, the finance provider pays EUR 178,200 to the small company (a 1 percent discount reflecting the prime contractor's AA credit rating). The prime contractor pays the finance provider EUR 180,000 on the 30th day after invoice approval. The small company has avoided a 30-day working capital gap at a cost of EUR 1,800, substantially less than the EUR 5,400 it would have paid on its own factoring facility at a 3 percent rate.

Frequently Asked Questions

Is supply chain finance the same as factoring?

No. In standard factoring, the supplier initiates the transaction based on its own credit. In reverse factoring, the buyer initiates or enables the programme and the financing cost is based on the buyer's credit. The practical outcome (early cash for the supplier) is similar, but the cost and structure differ materially. Reverse factoring is generally cheaper for SMEs with limited credit history than conventional factoring.

Can the use of supply chain finance be required in a public contract?

A contracting authority can encourage or facilitate supply chain finance but cannot typically require a prime contractor to operate a specific SCF programme as a contractual obligation: that would amount to a prescriptive financial service requirement that may interfere with commercial relationships. However, the availability of an SCF programme can be included as a scored element of social value criteria if it is linked to the delivery of the contract and the wellbeing of the supply chain.

Does supply chain finance create balance sheet implications for the buyer?

Supply chain finance programmes structured as approved payables finance may or may not need to be recognised on the buyer's balance sheet depending on the accounting standards applicable and the specific programme terms. Public sector buyers using SCF programmes should take accounting advice to ensure that the arrangements do not create undisclosed liabilities. This is a known area of scrutiny in the UK following several large corporate supply chain finance controversies.
