What it means
Every time a supplier ships goods before being paid, they are granting commercial credit. That gap between delivery and payment funds the buyer's operations at the supplier's expense, which is why credit terms are negotiated as hard as price in many industries.
The same idea applies when a bank grants a company a revolving facility rather than a fixed loan. The reason commercial credit matters so much is that it is usually the largest and cheapest source of short-term funding a business has.
A company with $6,000,000 of annual purchases on 45-day terms is being financed by its suppliers to the tune of roughly $740,000 at any moment. Losing those terms after a late payment can create a cash hole far larger than the disputed invoice.
Commercial credit is granted on assessment, not goodwill. Suppliers and lenders look at filed accounts, payment history, trade references and often a credit agency score, then set a limit and terms accordingly.
Newer businesses frequently start on pro forma terms, meaning payment before delivery, and earn better terms only after a clean run of settled invoices. The nuance that catches people out is the discount.
Terms quoted as 2/10 net 40 mean you may take 2% off if you pay within 10 days, otherwise the full amount is due on day 40. Skipping that discount to keep the cash for another 30 days is a financing decision, and the implied annual cost is often far higher than a bank overdraft.
There are structured variants too. Supply chain finance lets a supplier get paid early by a bank against the buyer's stronger credit, while invoice discounting lets the seller borrow against receivables it has already issued.
Both are ways of converting commercial credit into cash sooner, at a price.
In practice
Real-world examples.
Example
A garden furniture retailer negotiates 60-day terms with its main importer ahead of the spring season. That extra credit lets it stock $300,000 of product before any of it sells, so the season is funded by the supplier rather than the bank. The importer agrees only after seeing two years of clean payment history.
Example
A commercial printing firm loses 30-day terms with its paper merchant after two payments run 20 days late. The merchant switches it to payment on delivery, and the printer suddenly needs $180,000 of cash it had been quietly borrowing from the supplier for years. The finance director arranges an invoice discounting facility to plug the gap.
Example
A fast-growing coffee roastery uses supply chain finance so its farm suppliers can be paid within 7 days while the roastery still pays on day 75. The bank charges a fee based on the roastery's own credit standing, which is stronger than the farms' standing. Both sides gain, and the roastery keeps its suppliers loyal in a tight harvest year.
Formula
Calculation
Annualised cost of forgoing an early payment discount = [discount % / (100 - discount %)] x [365 / (full term days - discount period days)]
A distributor is offered terms of 2/10 net 40 on $500,000 of annual purchases. Taking the discount means paying on day 10 and saving 2%; skipping it means paying the full amount on day 40.
Discount ratio = 2 / (100 - 2) = 2 / 98 = 0.020408
Extra days of credit gained = 40 - 10 = 30 days
Periods per year = 365 / 30 = 12.1667
Annualised cost = 0.020408 x 12.1667 = 0.2483, or about 24.8% a year
If the same distributor can borrow on an overdraft at 9% a year, it is clearly cheaper to draw the overdraft, pay on day 10 and capture the 2% discount on every invoice.Case study
Seen in the real world.
Halberd Tooling Group is a fictional, illustrative maker of precision cutting tools with revenue of $14,000,000. It bought roughly $5,000,000 of steel and consumables a year, always on standard 2/10 net 40 terms, and always paid on day 40 because the finance team saw the extra 30 days as free cash.
A new controller ran the numbers and showed the board that forgoing the discount was costing about 24.8% a year in effective interest, or roughly $100,000 of foregone discounts on $5,000,000 of purchases. The company arranged a $450,000 overdraft priced at 9%, drew on it to pay every supplier on day 10, and captured the discounts.
In this illustrative case the switch cost about $40,500 of interest at the full drawn amount and saved $100,000 of discounts, a net gain of roughly $59,500 a year. The wider point is that commercial credit always has a price, even when nobody sends an interest statement.
Watch out
Common mistakes.
- Believing supplier credit is free, when the early payment discount you skip is the interest charge in disguise.
- Stretching payables to the last possible day without warning suppliers, then being surprised when terms are withdrawn.
- Confusing the credit limit a supplier sets with the credit you can actually afford to use given your own collections.
Questions
People also ask.
How is commercial credit different from consumer credit?
It is extended to a business rather than an individual, so it is assessed on trading history and filed accounts and is generally outside consumer lending protections.
What is the fastest way to improve the commercial credit available to us?
Pay on agreed terms consistently, file accounts on time rather than at the deadline, and give trade references that will actually respond.
Does taking supplier credit hurt our credit score?
Using it does not, but paying late does, because payment behaviour is the main input to most business credit scores.
