The 2% Discount That's Really a 36% Interest Rate

You've got a supplier invoice sitting on the desk. Down in the corner, in small type, it says 2/10 net 30. Cash is tight — it's restoration, cash is always tight — so you do the responsible-feeling thing and pay it on day 30. Hold the money as long as you can.

That instinct is costing you one of the best returns available to your business. The small print you're ignoring is a finance decision, and most owners get it backwards.

What "2/10 net 30" actually says

The terms mean: pay the invoice within 10 days and take 2% off; otherwise the full amount is due in 30 days. Two percent on a materials bill looks like a rounding error, so it's easy to wave off.

Here's what you're really deciding. If you skip the discount, you keep your cash for 20 extra days — the difference between day 10 and day 30 — and in exchange you pay 2% more. So the question isn't "is 2% a big deal?" It's "is holding my cash for 20 days worth paying 2% for it?"

Annualize it and the answer is obvious. There are roughly eighteen 20-day periods in a year, and you're paying about 2% for each one. Run it through the standard cost-of-credit formula and 2/10 net 30 works out to an effective annualized rate of 36.72% (AccountingTools, "Credit terms and the cost of credit"). Give or take the day-count convention, skipping that 2% discount is like borrowing money at 36% a year.

Now flip it around, because that's the useful part. Paying early to grab the 2% isn't saving 2% — it's earning about 36% annualized on that cash for the 20 days you put it to work. There is almost nothing else you can do with 20-day money that pays like that. Your line of credit doesn't cost 36%. A money-market account doesn't pay anything close. The discount is a better return than most of the "smart" uses of cash you're agonizing over.

The restoration translation

Restoration runs on a specific, sensible instinct: guard your cash, because the carrier pays on its own slow clock and you're financing the gap. That instinct is right. But it points owners at the wrong target — and this is where it costs you.

On the bills you pay (materials, equipment, subs), hoarding cash to pay on day 30 feels prudent and is usually a mistake. If you can fund an early payment from your line of credit at, say, 9% and capture a discount worth ~36% annualized, you're netting roughly 27% for doing it. You'd have to be turned down for credit entirely — literally unable to get the cash at any reasonable rate — for skipping the discount to be the right call. "We're tight this week" is not that situation; that's exactly what the line of credit is for.

On the bills you send, the same math cuts the other way. Restoration owners, desperate to pull cash in faster, sometimes offer early-pay discounts — on deductibles, on direct-pay jobs, on the non-carrier work. Understand what you're handing over. Offering 2% to get paid 20 days sooner means you are paying ~36% annualized to accelerate money you're already owed. When you hold lien rights, a documented claim, and a real collections process, you rarely need to buy speed at credit-card-times-two prices. Don't discount your way out of a collections problem you can solve with paperwork.

One caveat worth stating plainly: your carrier isn't taking an early-pay discount from you, and you shouldn't offer one. This is about your suppliers and your non-carrier receivables — the parts of the cash cycle you actually control.

Four moves that turn the terms in your favor

1. Read the terms on every supplier invoice. You can't manage a discount you never noticed. Know which vendors offer one and what it is.
2. Compare each discount's annualized cost to your line-of-credit rate. If the discount beats the rate — and a 2/10 almost always does — take it, and fund it with the line if you have to. That's not spending cash you don't have; it's arbitrage.
3. Stop giving away early-pay discounts on AR you can collect another way. Progress billing, prompt ACV billing on approval, and preserved lien rights get you paid without buying speed at 36%.
4. Negotiate terms in both directions. From suppliers who don't discount, ask for longer net terms (net 45 or 60) — that's free float. From those who do, make sure someone's actually catching the discount window instead of paying on day 30 out of habit.

None of this is exotic finance. It's reading the small print like it's a number, because it is one. The gap between the owner who takes every discount that beats his credit line and the one who pays everything on day 30 "to be safe" is real money, every month, forever.

That's the kind of decision a fractional CFO puts on rails — so you're not eyeballing it invoice by invoice, and the profitable choice is the default one. If you've never run the annualized cost on your own vendor terms, that's a good first conversation.
