Invoice payment terms are the conditions that spell out when and how your client should pay — Net 30, due on receipt, and early-payment discounts are the most common. The terms you choose have a direct impact on your cash flow, so they're worth choosing deliberately rather than copying whatever you saw last. This guide explains each term, how late fees work, and where terms belong on your invoice.
"Net" simply means the number of days the client has to pay in full after the invoice date. Here's what you'll encounter:
| Term | What it means | When to use it |
|---|---|---|
| Due on receipt | Payment expected immediately upon delivery | Small jobs and first-time clients |
| Net 10 / Net 15 | Full payment due within 10 or 15 days | Regular clients and quick-turnaround work |
| Net 30 | Full payment due within 30 days | The standard for most business-to-business work |
| Net 60 | Full payment due within 60 days | Large corporate clients with slow payables |
| 2/10 net 30 | 2% discount if paid within 10 days, otherwise net 30 | When getting cash faster is worth a small discount |
Net 30 is the default in most industries — familiar, expected, and rarely questioned. Shorter terms (Net 10, Net 15, due on receipt) are appropriate for smaller amounts, new relationships, or consumer-facing work where long credit makes no sense. Net 60 usually isn't your choice at all; it's imposed by big companies whose procurement departments simply pay on their own schedule.
The notation "2/10 net 30" offers the client a deal: take 2% off if you pay within 10 days; otherwise the full amount is due in 30 days. On a $1,000 invoice, paying by day 10 costs the client $980 — you trade $20 for getting cash 20 days sooner. Before offering this, do the math honestly: giving up 2% to get paid 20 days early annualizes to roughly a 36% cost of capital, which is expensive money. It makes sense when you're cash-constrained and the alternative is a credit line, but not as a permanent policy for healthy businesses. If you do offer it, state the discounted amount and the exact deadline on the invoice — "Pay $980 by October 25, or $1,000 by November 14" leaves no room for confusion.
Late fees are enforceable only if the client agreed to them in advance — which is exactly why your payment terms must appear on the invoice (and ideally in your contract too). A typical structure is 1% to 1.5% per month on the overdue balance, sometimes with a flat minimum like $25. State rules vary: some states cap late fees or interest on certain transactions, and a few require specific disclosures, so check your state's rules before setting a policy. Two practical tips: start charging the fee exactly when your terms say you will — empty threats train clients to ignore deadlines — and always send a polite reminder before the fee hits, since most late payments are disorganization, not malice.
Your payment terms are really a lending decision: Net 30 means you're extending every client a 30-day interest-free loan. A business doing $10,000 a month on Net 30 is perpetually carrying about $10,000 in receivables — money earned but not yet in hand. Shorten terms to Net 15 and that float roughly halves. This is why fast-growing businesses often feel cash-poor despite healthy sales: revenue booked is not revenue banked. Match your terms to your reality — if you pay your own suppliers and subcontractors weekly, billing clients on Net 30 means you're financing the gap. New businesses should start strict (due on receipt or Net 15) and extend longer terms only to proven, reliable clients.
Payment terms belong in two places: near the total amount due, where the client's eye naturally lands, and in a dedicated terms or notes section at the bottom of the invoice. The near-total placement might read "Due November 14, 2026 (Net 30)"; the terms section carries the full policy, including any early-payment discount and late-fee schedule. Put terms on every single invoice — even for long-standing clients — because the invoice is often the document that actually gets enforced if a payment dispute arises. If your terms ever change, the invoice in hand always reflects the current policy.
Net 30 means the client owes the full invoice amount within 30 calendar days of the invoice date — not 30 business days, unless your terms say otherwise. It's the most common payment term in business-to-business transactions. Always pair it with an explicit due date on the invoice so there's no ambiguity about which day is day 30.
It sets a clear expectation, but in practice almost nobody pays the literal day they receive an invoice — most clients process it within a few days to a week. Its real value is psychological: it signals that you expect prompt payment, unlike Net 30 which normalizes waiting a month. Pair it with easy payment methods to remove friction.
Yes, if the late-fee policy was stated in your payment terms or contract before the work was done — you generally can't add fees retroactively. Typical rates run 1% to 1.5% per month on the overdue balance. Check your state's laws first, since some states cap late fees or require specific disclosures for certain transactions.
Only if you need cash faster more than you need the margin. A 2% discount for paying 20 days early (2/10 net 30) sounds small but annualizes to about 36% — far more expensive than most credit lines. It's a reasonable short-term tool when cash is tight, but a poor permanent policy for a healthy business.
Put a short version next to the total due — for example, 'Due November 14, 2026 (Net 30)' — and the full policy in a terms or notes section at the bottom, including early-payment discounts and late fees. Repeating terms on every invoice matters because the invoice is the document most likely to be referenced in a payment dispute.
