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

Net 15 means the full invoice amount is due 15 days after the invoice date. Net 30 gives the client 30 days; 2/15 Net 30 offers a 2% discount for paying within 15 days; Due on Receipt asks for payment as soon as the client receives the invoice.

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.

"Due upon receipt" means exactly the same thing — the two phrases are interchangeable, so use whichever your client already uses. "Net 30 vs Due on Receipt" is the choice most businesses wrestle with: Net 30 gives the client 30 days, Due on Receipt asks for payment now. And watch out for a third variant, "30 days upon receipt of invoice": that means payment within 30 days of the client receiving the invoice, so the clock starts on receipt rather than the invoice date. Whichever you mean, spell it out — never assume the client reads it the way you do.

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.

Net 45

"Net 45" gives the client 45 days to pay — the middle ground between Net 30 and Net 60. It shows up a lot with agencies, larger suppliers and contractors whose clients run monthly payment cycles. If Net 30 strains your client's process but Net 60 would strain your cash flow, Net 45 is the compromise worth proposing.

Net 90 and Net 120

"Net 90" and "Net 120" mean 90 and 120 days — three to four months of waiting. You will only meet these on enterprise and wholesale contracts, where the buyer's payment machinery moves slowly. For a freelancer or small business they are effectively an interest-free loan to your client: accept them only if the job is big enough to carry the wait, and price accordingly.

2/15 Net 30: the early-payment discount

"2/15 Net 30" is the sibling of 2/10 Net 30: the client gets a 2% discount if they pay within 15 days, otherwise the full amount is due in 30 days. On a $1,000 invoice that is $20 saved for paying two weeks early — small enough that you barely feel it, large enough that many clients take it. The "2/15" part is the discount and its window; the "Net 30" part is the final deadline. If you see "2/15 net 30 meaning" searched, this is the answer: discount first, deadline second.

EOM and net monthly terms

EOM means End of Month: payment is due by the end of the month in which you invoiced. It is handy when you bill mid-month and want everything settled by month-end. You will also see it written as "net monthly" or "30 days net monthly" — the clock runs from month-end rather than the invoice date, so "30 days net monthly" usually means 30 days after month-end. Wording varies by contract, so confirm whether yours means payment by month-end or month-end plus 30 days before you rely on it.

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. Contractors usually pair terms with staged billing — deposit, progress payments, final balance — rather than a single due date; the contractor invoice template is built for that rhythm.

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." The late fee calculator works out the amount for you. If the due date passes unpaid, the payment reminder generator drafts the chase for you. Our full guide on how to write an invoice covers everything else that belongs on the page.
