"2/10 Net 30" is shorthand for a deal: the full invoice is due in 30 days, but the client can take 2% off if they pay within 10 days. It's a price you pay to move money forward by about three weeks. Sometimes that trade is clearly worth it, sometimes it's giving away margin for nothing — the math below shows which is which.
How the mechanic works
The notation is always discount / discount window, Net full term:
| Terms | Meaning |
|---|---|
| 2/10 Net 30 | 2% off if paid within 10 days; otherwise full amount due in 30 |
| 1/10 Net 30 | 1% off within 10 days; full amount in 30 |
| 2/10 Net 60 | 2% off within 10 days; full amount in 60 |
Two mechanical details matter. First, the invoice shows the full amount — the discount is conditional, so it lives in the terms text, not in the invoice's discount field (that field is for unconditional discounts, and using it would let a slow payer take the reduced price at day 30). Second, define when the clock starts (invoice date) and what counts as "paid" (funds received, not check mailed).
The worked math
Take a $5,000 invoice on 2/10 Net 30:
- Client pays by day 10: they pay $4,900 — the discount costs you $100.
- You received $4,900 roughly 20 days earlier than day 30 (in reality often 30+ days earlier, since Net 30 invoices routinely drift to day 40+).
Is $100 a good price for 20 days? Annualize it: giving up 2% to move money 20 days forward is equivalent to paying interest at roughly 2% × (365 ÷ 20) ≈ 36% per year. That's expensive money. If you'd otherwise cover the gap with a credit card at ~24% APR, the discount is only slightly worse and far less stressful. If you have a comfortable cash buffer, you're paying credit-card-level interest for cash you didn't need.
This is exactly why sharp corporate AP departments love these terms — capturing 2/10 Net 30 earns them an excellent return — and why you should offer them deliberately, not by default.
When it's worth the margin
Offer an early-payment discount when:
- Cash flow is the binding constraint — the discount is cheaper than an overdraft, a missed opportunity, or a late payroll.
- The client is large and reliably slow. A company that always pays at day 45–60 but has a discount-capture program will often pay in 10 days when 2% is on the table. You're not discounting a payment you'd have had anyway; you're buying five weeks.
- The invoice is large. The mechanic has fixed conversational overhead; it's worth it on a $12,000 invoice, not a $300 one.
Skip it when clients already pay promptly (you'd be donating 2%), when your margins are thin (2% of revenue can be 10%+ of profit on a 20%-margin business), or when the real problem is that your terms are too long — in that case just shorten them (Net 30 vs Net 15 vs Due on Receipt). Many small businesses get better results from a deposit plus a late-fee clause, which protect cash flow without giving up margin.
Wording on the invoice
Keep the terms line explicit — spell out both amounts and both dates so nobody has to decode the shorthand:
"Terms: 2/10 Net 30. Full amount $5,000 due October 10. If payment is received by September 20, deduct 2% and pay $4,900."
Example: invoice offering 2/10 Net 30
The invoice shows the full amount; the conditional discount is spelled out in the terms with both amounts and both dates.
When the client takes the discount, record the 2% as a discount on your books rather than editing the original invoice — your accountant will thank you.
An early-payment discount only works if the invoice states it unambiguously. InvoiceKo gives you a free, clean invoice with a full terms field — no signup, no watermark, PDF generated in your browser — and for the rest of your terms toolkit, see invoice payment terms examples.
