A large buyer wants to pay in ninety days and its supplier needs cash in ten. Supply chain finance resolves that conflict by inserting a lender between them.
The working capital conflict
Extended payment terms improve a buyer's cash position by delaying outflows. The same terms worsen the supplier's, since it has already produced and shipped.
Suppliers can borrow against the receivable, but a small firm borrows at its own credit standing, which is usually weak. The cost of that borrowing is embedded in the price it charges.
Both parties are worse off than necessary. The buyer pays a higher price to fund the supplier's expensive borrowing.
How the programme is structured
Once the buyer approves an invoice, it becomes an irrevocable obligation of the buyer rather than a claim contingent on delivery. A bank will advance against that obligation at the buyer's credit rate.
The supplier receives payment early, less a discount reflecting the buyer's cost of funds. The bank is repaid by the buyer on the original due date.
Because the risk is the buyer's, the discount is far smaller than the supplier's own borrowing cost. That difference is the value the programme creates.
Why the accounting treatment is contested
The buyer's obligation looks like trade payables but functions like bank borrowing. Whether it should be reclassified as debt has been a persistent question.
Reclassification matters because payables are excluded from most leverage measures while debt is not. A company using these programmes heavily can appear less leveraged than it is.
Disclosure requirements about programme size and terms have been introduced in several reporting regimes. Requirements differ by jurisdiction and continue to be developed.
The dependence that builds up
Suppliers plan cash flows around early payment once it is available. The programme becomes part of their working capital rather than an option.
If the bank withdraws or the buyer's credit deteriorates, that funding disappears at short notice. Suppliers must then finance the full payment term themselves.
Because the withdrawal follows buyer stress, it arrives when suppliers are least able to absorb it. The concentration of risk is the recurring criticism.
How it differs from ordinary factoring
Factoring is arranged by the supplier, who sells its receivables and bears the cost at its own credit standing. The buyer need not participate or even know.
Supply chain finance is arranged by the buyer for its whole supplier base and priced on the buyer's credit. The economics and the control sit on opposite sides.
Both are widely used in cross-border trade, where payment cycles are longest. The choice usually reflects which party has the stronger banking relationship.
