A cash discount is a small reduction off an invoice that a seller offers to a buyer for paying early, usually written as a percentage within a set number of days, such as 2/10 net 30. Take the discount if you pay inside the window; pay the full amount if you do not. It is also called an early payment discount, and in UK and Commonwealth usage a settlement discount.
The seller's goal is to pull cash in sooner and cut the risk of slow or unpaid invoices. The buyer's goal is a genuine saving. The detail most people miss is how large that saving is when you annualise it, which is the difference between a discount being a nice-to-have and a no-brainer. A cash discount sits in the wider world of accounts receivable as one of the few levers that changes customer behaviour rather than just measuring it: priced right, it nudges buyers to pay weeks earlier, which lifts cash flow and lowers the share of your ledger that ever goes overdue.
Pay early, pay less.A percentage off the invoice for settling inside a short window, e.g. 2/10 net 30.
It is a cash-flow tool.Sellers use it to shorten days sales outstanding and collect faster.
The implied rate is high.2/10 net 30 is roughly a 37% annualised return, so it is usually worth taking.
Multiply the invoice by the discount percentage to get the saving, then subtract it for the amount due if you pay early. The figure that really matters, though, is the annualised cost of skipping the discount, because that tells you whether early payment beats holding onto your cash. Enter your terms below.

That last figure is the whole point. Turning down 2/10 net 30 is like borrowing at roughly 37% a year, far above the cost of almost any financing, so if you have the cash a buyer should nearly always take it. The early payment discount calculator lets you compare offers side by side, and 2/10 net 30 breaks down the most common terms in detail.
A cash discount rewards fast payment and is applied at the point of payment; a trade discount is a reduction off list price for a type of customer or order, and it is applied before the invoice is even raised. They answer different questions. A trade discount asks "what price does this customer get?" and is baked into the invoice total. A cash discount asks "how quickly will they pay?" and only applies if the buyer settles inside the window. A wholesaler might give a retailer 30% off list as a trade discount, then offer a further 2% cash discount for paying within ten days. The table below lines up the cash discount against the others you see on invoices.
| Discount type | What it rewards | When it applies |
|---|---|---|
| Cash / early-payment discount | Paying the invoice quickly. | At payment, if inside the discount window. |
| Trade discount | Being a certain class of buyer (reseller, wholesaler). | Before the invoice; off list price. |
| Volume / bulk discount | Ordering a larger quantity. | At order, based on units bought. |
| Settlement discount (UK term) | The same as a cash discount. | At payment, if inside the window. |
Offer a cash discount when collecting sooner is worth more to you than the margin you give up, which is usually the case if you are short on cash or carrying a lot of slow-paying customers. A 2% discount feels cheap if it turns a 45-day payer into a 10-day payer and saves you chasing. It feels expensive if your customers already pay on time, because then you are simply handing money to people who would have paid anyway. The honest answer is to look at your ledger: if a big share of invoices drift past due, a cash discount can be a cheaper lever than financing or write-offs.
Compare a discount with the other ways to close the same cash-flow gap, because the same problem might be solved by tighter payment terms, a deposit up front, or simply faster, firmer follow-up, none of which costs you margin on every invoice. There is a smarter version of the discount itself, too. Rather than one fixed offer, dynamic discounting scales the discount to how early the customer pays, so the buyer who pays on day two gets more off than the one who pays on day nine. Whatever you choose, the terms only work if they are applied consistently and chased properly, which is where automation earns its keep. Prompt payment discounts in Paidnice apply these terms automatically in Xero and QuickBooks, so the discount, the deadline and the reminder all happen without anyone keying it in.
Most of the value leaks out through a handful of avoidable errors. Watch for these four before you commit any discount to an invoice template.
If your customers already pay inside terms, a standing 2% off is pure margin given away for nothing. Tie any discount to a real collection problem, not habit.
A buyer who pays on day 20 but still deducts the 2% has rewritten your terms. Wave it through once and you have set a precedent, so decide your policy on short payments first.
2% for paying 20 days early is generous; the same 2% for paying just 5 days early is enormous, well over 100% annualised. Run the terms through the calculator first.
If the deduction lands and no one reconciles it against the invoice, your receivables ledger slowly drifts out of line with reality.
For the seller, a cash discount taken by the customer reduces revenue, so the invoice value comes down by the discount when the customer pays early. For the buyer, it reduces the cost of the purchase. Under modern revenue recognition rules, sellers are generally expected to estimate the discounts customers will take and net them off revenue up front, rather than waiting and recording each one only when it happens. In day-to-day bookkeeping in Xero or QuickBooks, the early payment is matched to the invoice and the small shortfall is posted to a discounts account, keeping the receivable clean and the books accurate.
