Supply Chain Finance: a Worked Example

The creditors look like trade. They behave like a loan.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED

// THE SHORT ANSWER

For a lender to the buyer, supply chain finance raises one question: how much of the creditor balance would have to be paid in cash if the programme stopped. Suppliers join because they can sell the buyer's approved invoices to a financier and be paid within days, at a price set by the buyer's stronger credit, and the buyer uses that to ask for longer terms. The extra creditors are funded, in substance, by the financier. They flatter net debt and leverage while the programme runs, so a lender treats them as borrowing that can be withdrawn, and asks the size of it.

The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.

// 01 — WHY A LENDER READS IT AS BORROWING

A supplier that sells on 45-day terms is lending to its customer for 45 days, at a price built into the goods. Supply chain finance, which the industry's standard definitions call payables finance, puts a third party into that chain. The buyer sets up a programme with a financier and invites its suppliers to join. A supplier that wants its money sooner sells its approved invoices to the financier, receives their value less a discount priced on the buyer's credit, and the buyer pays the financier when the invoice falls due.

The programme becomes a lending question when the buyer uses it to stretch its terms. Suppliers accept 90 days instead of 45 because they can draw cash at day ten at a price set by a stronger credit than their own. The buyer now owes for twice as long, and the extra balance is owed in substance to a financier, not to a supplier who will keep shipping. If the financier withdraws or the programme shrinks, suppliers ask for their old terms back and the buyer pays the difference in cash.

// 02 — HOW IT MOVES THE NUMBERS

Creditors = daily purchases × days taken to pay
Extension = programme purchases per day × (new terms − old terms)
One-off cash released = extension, in the year the terms lengthen
Lender's view of debt = reported debt + extension (or + whole programme balance)

Three things move together. Creditor days rise. Operating cash flow improves once, in the year the terms lengthen, and not again. And net debt falls by the cash released, which flatters every leverage covenant. Whether the accounts keep the balance in trade payables or show it as borrowing depends on the arrangement's terms; programmes are commonly structured to stay in payables, which is why lenders make their own adjustment.

// 03 — THE EXAMPLE

A packaged-food manufacturer, constructed for this page like every figure in it, buys US$146m of ingredients and packaging a year, or US$400,000 a day, and pays at 45 days. It has US$40m of bank debt, US$4m of cash and EBITDA of US$15m. It launches a programme; suppliers covering half its purchases join and move to 90-day terms. In US$ millions:

Creditors before: 0.4 × 45 = 18.0 (45 days)
Creditors after: 0.2 × 45 + 0.2 × 90 = 9 + 18 = 27.0 (67.5 days)
Cash released: 27.0 − 18.0 = 9.0
Leverage before: (40 − 4) ÷ 15 = 36 ÷ 15 = 2.4×
Leverage after: (40 − 13) ÷ 15 = 27 ÷ 15 = 1.8×
Extension as debt: (27 + 9) ÷ 15 = 36 ÷ 15 = 2.4×
Programme as debt: (27 + 18) ÷ 15 = 45 ÷ 15 = 3.0×

Leverage falls by more than half a turn and the business has not changed. Adding back the extension restores the old 2.4 times, which is the lender's honest starting point. Treating the whole programme balance as debt gives 3.0 times, the reading of a lender that doubts the suppliers would return to 45 days at all. If the financier withdrew, the US$9m would leave over roughly the following three months as programme invoices fell due and new purchases reverted to the old terms. That is the size of the call on liquidity the lender tests against undrawn facilities.

// 04 — WHAT THE ACCOUNTS NOW SHOW

Amendments to the international standards issued in 2023 require buyers to disclose these arrangements: their terms, the liabilities inside them and how much of those the financier has already paid, the range of payment due dates beside comparable trade payables, and the liquidity risk. The changes to IAS 7 and IFRS 7 apply to periods beginning on or after 1 January 2024, and New Zealand and Australia adopted them for the same periods. The reach differs below the top tier. Australia extended the disclosures to its simplified Tier 2 reporters. New Zealand's reduced-disclosure regime exempts Tier 2 for-profit entities from all of them. The UK's FRS 102, used by most mid-market groups there, added similar disclosures from periods beginning on or after 1 January 2025.

So a lender may find the programme laid out in a note, or find nothing and have to ask. It is the nearest neighbour of factoring and invoice discounting, with one difference that decides the pricing: those are arranged by the seller and priced on the seller's customers, while this is arranged by the buyer and priced on the buyer. Dynamic discounting is the version without a financier, paid from the buyer's own cash.

// 05 — WHERE IT DECIDES A FILE

In the buyer's file it decides the covenant definitions and the liquidity test. A lender can bring programme balances into the net debt definition, cap the amount that sits outside it, or ask for the balance on each compliance certificate. It decides how the cash flow is read: a year in which operating cash flow jumped because terms were extended is not a year to project forward. And it decides the liquidity headroom the lender requires, measured on the day the programme stops rather than the day it runs smoothly.

In a supplier's file it reads the other way. Cash arrives early and debtor days fall, but the supplier has accepted longer terms, priced the discount into its margins, and come to depend on one buyer's programme and one financier's appetite.

// QUESTIONS PEOPLE ASK

Is supply chain finance debt?
In the accounts it usually stays in trade payables, because programmes are commonly structured so that the liability keeps the character of a trade creditor; the classification turns on the arrangement's terms. A lender often reads the part of the balance created by extended terms as borrowing in substance, because it is funded by a financier and can be withdrawn, and the buyer would then have to pay it in cash. Many lenders add that part, or the whole programme balance, to net debt in their own analysis.
What is the difference between supply chain finance and factoring?
Who arranges it and whose credit sets the price. Factoring and invoice discounting are arranged by the seller, which sells or borrows against its own invoices at a price reflecting its customers and itself. Supply chain finance is arranged by the buyer, which approves its suppliers' invoices for early payment by a financier at a price reflecting the buyer's credit. A small supplier to a large buyer can therefore be paid early more cheaply through the buyer's programme than through its own facility.
Who pays for supply chain finance?
The supplier pays the discount when it chooses to be paid early. The buyer may pay programme or platform fees, and gains the longer payment terms. Whether a supplier is better off depends on the terms it gave up: a supplier that moved from 45 to 90 days and draws at day ten pays a discount on a debt it used to collect at day 45. A supplier that would otherwise borrow at its own, higher rate may still come out ahead.
What happens if a supply chain finance programme is withdrawn?
Suppliers stop being able to sell the buyer's invoices, so they press for their old payment terms. The invoices already in the programme are paid to the financier on their due dates, and new purchases are paid sooner, so the creditor balance falls back and the cash released when terms lengthened goes out again within weeks or months. A buyer that has spent that cash needs another source of liquidity, which is why lenders test headroom against the programme's withdrawal.
