An early payment discount is a reduction a seller offers a buyer, commonly 1% or 2% of the invoice amount, for paying significantly before the invoice's full, final due date. It is the mechanism behind common credit terms such as "2/10, net 30," which allows a 2% discount if payment is made within 10 days, with the full amount otherwise due within 30 days.
How an early payment discount works for both sides
From the seller's perspective, an early payment discount, recorded as a sales discount, is the cost of getting cash into hand faster and reducing the risk that an outstanding receivable eventually becomes uncollectible the longer it remains open. From the buyer's perspective, the identical transaction is recorded as a purchase discount, a reduction in the cost of goods purchased, available only if the buyer chooses to pay within the shorter discount window rather than waiting until the full due date.
Why the implicit cost of skipping the discount is so high
Giving up a 2% discount to delay payment by only 20 additional days, the typical gap between a 10-day discount window and a 30-day final due date, works out to an annualized cost of roughly 36%, far higher than almost any short-term financing a buyer could arrange elsewhere. This is why a financially healthy buyer with available cash will almost always take an early payment discount when offered one, and why some buyers borrow specifically to take advantage of attractive early payment discounts, since the effective return from doing so typically exceeds the interest cost of short-term borrowing by a wide margin.
Why sellers offer early payment discounts at all
Sellers extend early payment discounts specifically to accelerate cash collection, which improves their own cash flow and working capital position, and to reduce exposure to the risk that an open receivable eventually goes unpaid. Even though offering a discount technically reduces revenue on sales where it is taken, many sellers view the trade-off favorably, since faster cash collection and reduced bad debt risk are often worth more to the business than the small percentage given up.
A simple worked example
A $5,000 invoice with terms of 2/10, net 30 can be settled for $4,900 if paid within 10 days, saving the buyer $100, or the full $5,000 if paid anytime up to day 30. A buyer that routinely pays late, missing the discount window entirely, is effectively leaving that $100 savings on the table every time, a cost many businesses track specifically because it adds up significantly across a full year of regular purchasing activity.
Why some buyers still skip the discount
Despite the high implicit cost of skipping an early payment discount, cash-constrained buyers sometimes forgo it anyway simply because they lack the cash on hand within the shorter discount window, even while recognizing that paying later costs them more in the long run. This tension is exactly why treasury teams at well-run companies prioritize having enough short-term liquidity specifically to capture available early payment discounts rather than letting a temporary cash squeeze force them to pay the higher effective cost of waiting.
