Invoice Payment Terms Explained: Net 30, Net 15, Due on Receipt

What payment terms mean, which ones fit your business, and the exact wording to use.

Payment terms are the part of your invoice that answers the client's first silent question: when do I actually have to pay this? Get them wrong and you wait weeks for money you earned. Get them right and you get paid on time, every time. Here's the plain-English guide.

What are invoice payment terms?

Payment terms are the agreed window between the invoice date and the due date. They appear on every professional invoice — usually near the bottom, next to the payment details — and they turn a vague expectation into a concrete deadline. An invoice without terms is just a polite request. An invoice with terms is an agreement.

Due on Receipt

The strictest common term: payment is expected as soon as the client receives the invoice. In practice, most clients treat "due on receipt" as "pay this week." It suits short, low-risk work — one-off gigs, quick jobs, first-time clients you're still sizing up. Just know that genuinely immediate payment is rare outside of point-of-sale; expect a few days.

Net 15

"Net 15" means the full amount is due 15 days after the invoice date. It's a popular middle ground for freelancers and small service businesses: generous enough not to spook clients, short enough that your cash flow doesn't stall. If you bill monthly and want the money within the same billing cycle, Net 15 is often the sweet spot.

Net 30

"Net 30" gives the client 30 days to pay. It's the business world's default — large companies and agencies often can't pay faster because of their internal approval chains, so Net 30 is standard on contracts with bigger clients. The downside: you're effectively giving a 30-day interest-free loan. Never accept Net 30 out of habit if your business can't afford the wait.

A few other terms you'll see

Net 7 — seven days; useful for repeat clients with fast payment habits. Net 60 — sixty days; common in enterprise and wholesale, painful for freelancers. EOM (End of Month) — payment due by the end of the invoice month; handy when you bill mid-month. 2/10 Net 30 — a 2% discount if paid within 10 days, otherwise the full amount is due in 30; a gentle nudge that speeds up many payments.

Which terms should you choose?

Match the terms to the relationship and the cash flow. New client? Shorter terms (Due on Receipt or Net 7) reduce your exposure. Trusted repeat client with a track record of paying fast? Net 15 keeps things smooth. Big corporate client? You'll probably have to accept Net 30 — and price accordingly, since you're carrying the cost. And if you've sent a proforma invoice first, remember that the clock starts on the final invoice, not the proforma.

Can you use different terms for different clients?

Yes — and you should. Payment terms are a business decision, not a logo. Many freelancers run Net 15 as the default, tighten it to Due on Receipt for brand-new clients, and allow Net 30 only for larger clients who genuinely need it. Keep a simple note of each client's terms so every invoice you send matches what you agreed. Consistency builds trust; flexibility keeps cash flowing.

The exact wording to put on your invoice

Vague phrases like "payment due soon" or "at your convenience" are where money goes to die. Write the terms as a specific date and a plain sentence:

  • Due on Receipt: "Payment due upon receipt of this invoice."
  • Net 15: "Payment due within 15 days — by 15 November 2026."
  • Net 30: "Payment due within 30 days of the invoice date — by 30 November 2026."

Also state how to pay — bank transfer details, a payment link, or your mobile wallet — right next to the terms. Every bit of friction you remove is a day shaved off your wait. And if you charge late fees, say so here too: "A 1.5% monthly late fee applies after the due date." Our full guide on how to write an invoice covers everything else that belongs on the page.
