Payment terms decide how long you wait to get paid, and how much room there is for a client to argue about it. Choosing terms that fit your business, and writing them clearly, gets you paid faster and with fewer awkward conversations.
What payment terms are
Payment terms are the conditions attached to how and when an invoice gets paid: the deadline, any discount for paying early, and any fee for paying late. They belong on every quote, contract and invoice you send, not just the invoice. A client who agreed to terms in writing before the work started has far less room to push back once the invoice arrives.
Terms are usually written as a short code, like "net 30" or "due on receipt," plus, if you use one, a currency and a payment method. The wording doesn't need to be formal. It does need to be the same everywhere the terms appear, so a contract that says net 15 and an invoice that says net 30 don't quietly disagree with each other.
Common payment terms and what they mean
| Term | What it means |
|---|---|
| Due on receipt | Payment is expected as soon as the client gets the invoice. |
| Net 7 | Due 7 calendar days after the invoice date. |
| Net 10 | Due 10 calendar days after the invoice date. |
| Net 15 | Due 15 calendar days after the invoice date. |
| Net 30 | Due 30 calendar days after the invoice date; the most common term for freelance and business-to-business work. |
| Net 45 | Due 45 calendar days after the invoice date. |
| Net 60 | Due 60 calendar days after the invoice date; common with larger companies and agencies. |
| Net 90 | Due 90 calendar days after the invoice date; long, and worth negotiating down where you can. |
| EOM | Due at the end of the month the invoice was issued, sometimes combined with a term, like EOM 30. |
| 2/10 net 30 | A 2% discount if paid within 10 days; the full amount is due within 30 days either way. |
| CIA / CWO | Cash in advance or cash with order: payment is due before you start the work. |
| Deposit plus balance | Part of the fee upfront, with the rest due on delivery or a set date. |
| Milestones | The total fee is split and invoiced as agreed stages of the work are completed. |
All of these count calendar days, not business days, unless you explicitly say otherwise. Weekends and holidays don't pause the clock; they just mean the due date sometimes lands on a day the client's accounts team isn't working, which is worth planning around rather than fighting. If you'd rather not count by hand, the net 30 calculator for due dates works out the exact date for you.
Which payment terms suit freelancers and small studios
For a brand-new client, due on receipt or a deposit before you start protects you if the relationship doesn't work out. Once you've worked with someone a few times and been paid on time, net 15 or net 30 is a reasonable, widely expected middle ground.
Be cautious with net 60 or net 90. Some larger companies and agencies insist on them, and you may not have much room to negotiate, but a long payment term means you're effectively financing the client's business for two or three months. If you can't avoid it, factor that wait into your rate, or ask for a deposit to cover part of the gap.
Whatever you choose, put it in writing before the work starts, not as a surprise on the final invoice. A client who agreed to net 30 in a contract or a quote has far less standing to argue about it later than one seeing the term for the first time on an invoice.
How to write payment terms on an invoice
Keep the wording on the invoice itself short and unambiguous. Here's how that looks for three common setups.
When to send: Any standard term, once you and the client have agreed on one
Payment terms: [Payment term]. Invoice date: [Invoice date]. Amount due: [Amount]. Due date: [Due date]. Please send payment to [Payment details] or pay online at [Payment link].
Why it works: the same five lines work for net 30, net 15, due on receipt or whatever you've agreed — swap in the term, the exact due date and how to pay, and there's nothing left for the client's accounts team to look up.
When to send: A new client or a larger project
Payment terms: 50% deposit due on receipt, balance of [Balance amount] due on [Due date]. This invoice: [Invoice number] for the deposit of [Deposit amount]. A separate invoice for the balance will follow on delivery.
Why it works: it protects you if the project stalls, and tells the client exactly what's being billed now versus later.
When to send: When you want to encourage faster payment
Payment terms: 2/10 Net 30. Pay within 10 days of the invoice date for a 2% discount ([Discounted amount]); otherwise the full amount of [Amount] is due within 30 days.
Why it works: it gives the client a reason to pay early without threatening a penalty if they don't.
Late fees and interest in your payment terms
A late fee or interest charge only holds up if you agreed to it before the work started. State the rate and the trigger date directly in your contract, and repeat the wording on the invoice, rather than adding a fee after the fact.
If your client is a UK business, the law sets a default even without a contract: a payment counts as late 30 days after the invoice for public-sector work, or 60 days for a private business deal, unless you agreed a different date (Late commercial payments: charging interest and debt recovery). Once a payment is late, UK businesses can normally charge statutory interest of 8% plus the Bank of England base rate, unless the contract already sets its own rate (Charging interest on a commercial debt).
For clients in the EU, the rules work in a similar way: interest can start 30 days after the client receives the invoice, and the creditor is also entitled to a flat compensation fee for the cost of chasing the payment, on top of any interest (B2B late payments: interest, penalties and compensation).
In the US, there's no single federal late-fee rate for freelance or small business invoices. What you're allowed to charge varies by state, so check your state's rules or ask an accountant before writing a specific percentage into a contract. What works everywhere: put your late-fee policy in writing before the work starts, so it's never a surprise.
Payment terms in contracts
A contract or statement of work should spell out the same terms as the invoice, plus a little more: the total fee or rate, the payment schedule (one invoice, a deposit and balance, or milestones), accepted payment methods, the currency if you work with clients abroad, and what happens if the client cancels partway through. Cross-reference the net 30 guide if that's the term you're using, so both sides know exactly how the due date is counted.
It also helps to say plainly what happens if a payment doesn't arrive: whether work pauses, whether a late fee applies, and who to contact about it. Vague contracts create the arguments that clear payment terms are meant to prevent. Once the invoice is out, a steady invoice reminder process, rather than an occasional one-off email, is what actually gets it paid on time. If it's still outstanding well past the due date, see how to handle a past due invoice instead of letting it sit.
For a large project, it's also reasonable to ask for payment upfront as a partial deposit, which reduces how much of the balance is exposed to a slow or difficult payer.
Frequently asked questions
What are standard payment terms?
There's no single standard, but net 30 (payment due 30 calendar days after the invoice date) is the most common choice for freelance and small business invoicing in the US, especially with larger or established clients. Newer or smaller relationships often use shorter terms instead, such as net 15 or due on receipt, or ask for a deposit before the work starts. The right choice depends on your own cash flow and how much leverage you have with a particular client.
What does net 30 mean?
Net 30 means the client has 30 calendar days from the invoice date to pay the full amount, with no early-payment discount attached. The invoice date counts as day zero. For example, January 1, 2026 plus 30 calendar days is January 31, 2026; 30 days is not necessarily the same date next month. It's one of the most common payment terms for freelance and business-to-business work, though net 15 and net 60 are also widely used depending on the client and industry.
What does 2/10 net 30 mean?
It combines a discount with a deadline: the client can take a 2% discount off the invoice if they pay within 10 days, otherwise the full amount is due within 30 days. The "2" is the discount percentage, the "10" is the discount window in days, and "net 30" is the final due date. It rewards clients who pay early without penalizing ones who take the full term, and it can genuinely speed up payment for a small percentage cost.
Can you change payment terms for an existing client?
Yes, but tell them before you send the next invoice, not on the invoice itself. A short note explaining the new terms and when they take effect avoids disputes and keeps the relationship on good footing. Most clients accept a reasonable change, such as moving from net 60 to net 30, especially if you explain that it helps you plan your own cash flow. Avoid changing terms retroactively on work already agreed.
What payment terms are best for a small business?
For most freelancers and small studios, a mix works best: due on receipt or a deposit for new clients, and net 15 or net 30 once trust is established. Shorter terms protect your cash flow, since you're financing the client's payment period out of your own pocket in the meantime. If a client insists on longer terms, such as net 60, consider raising your rate slightly or asking for a deposit to offset the wait.
