What Payment Terms Should You Put on an Invoice?

What payment terms on an invoice actually control

Payment terms are the short block of text that answers three questions for your client: when is this due, how should I pay, and what happens if I am late. Everything else on the invoice — line items, totals, your business details — describes the work. The payment terms describe the transaction.

Vague terms are one of the most common reasons a perfectly good invoice sits unpaid. "Payment due soon" is not a term. "Payment due 14 days from the invoice date, by bank transfer to the account below" is.

Net 14

Shorthand for payment due 14 days after the invoice issue date. Net 7 and Net 30 work the same way.

Due date

The calendar date on which payment is expected. It should be written out in full on the invoice, not merely implied by the term.

• The due date, written as an actual calendar date.
• How to pay — bank details, a payment link, or another method you accept.
• Which currency you are billing in and whether taxes are included.
• A short sentence on what happens if payment is late.
• A contact for billing questions, so the client does not have to guess.

How to choose a due date you can hold to

Pick terms based on your cash flow, not on what sounds tough. If your own bills land early in the month and you invoice late in it, Net 30 means covering a month of costs out of pocket. Net 7 or Net 14 is common for freelancers; larger companies often run Net 30 or Net 45 because of their internal approval cycles.

1. Set the issue date honestly — Use the date you actually send the invoice, not the date you finished the work. Backdating shortens the client's window and invites an argument.
2. Add your term to the issue date — Net 14 on an invoice issued 3 March means payment is due 17 March. Write that date on the invoice so the client does not have to do the arithmetic.
3. Check the day of the week — If the due date lands on a weekend or public holiday, say in the terms whether payment is expected the next working day.
4. Decide your late-payment position before you need it — Write the sentence once, keep it in your template, and apply it consistently. Introducing a penalty after the fact rarely goes down well.
5. Tell the client before the invoice arrives — Mention your terms in the estimate or quote so the due date is not a surprise when the bill lands.

What to write in the payment terms block

Keep it to a few lines. Clients read the total and the due date; everything else is reference material. Put the terms directly under the total so they are hard to miss, and use the same wording every time.

• "ASAP" — it gives the client nothing to diarise.
• "Standard terms apply" — the client does not have your standard terms.
• "Payment within a reasonable time" — reasonable to whom?
• A due date buried in a footnote or a separate attachment nobody opens.

Deposits, milestones, and staged payments

For anything longer than a couple of weeks, split the money. A deposit protects you from a client who disappears mid-project, and milestone billing keeps each amount small enough to be approved without a finance meeting.

• Deposit: a percentage up front, credited against the final invoice.
• Milestones: fixed amounts tied to defined stages, each invoiced as it is reached.
• Retainer: a recurring amount for ongoing availability, invoiced on a set schedule.
• Balance: whatever remains after deposits and milestone payments are credited.

When a client pays late

Late payment is normal, and most of it is administrative rather than deliberate — the invoice went to the wrong inbox, or it is sitting in an approval queue. Your terms give you a starting point for the follow-up.

• Check your own paperwork first: was the invoice sent to the right person, and does it match the approved estimate?
• Send a short, factual reminder the day after the due date.
• Reference the invoice number and the due date, not the client's character.
• Escalate politely and in writing if the first two reminders are ignored.
• Keep every message in one thread so the history is easy to find.

A repeatable sequence matters more than a cleverly worded email. Our guide to following up on unpaid invoices sets out a reminder schedule you can copy.

Keeping terms consistent from estimate to invoice

Your estimate, quote, and invoice should all point at the same terms. If the quote said Net 14 and the invoice says Net 30, the client will follow whichever suits them.

• Put your payment terms in the estimate so approval and expectations arrive together.
• Save the wording in a template instead of retyping it each time.
• Reuse saved clients and products so names, rates, and descriptions stay identical across documents.

Invoice Maker is an iPhone app that creates and shares PDF invoices and estimates, converts an estimate into an invoice, tracks paid and unpaid status, saves clients and products, and supports templates and reports. It stores your data on the device without a login. Start with the invoice maker, keep reusable details in clients and products, and use invoice tracking to see what is still outstanding. If you are quoting first, the estimate maker covers that side of the workflow.

Common payment-term mistakes to avoid

• Copying another company's terms without checking they fit your cash flow.
• Leaving the due date off because the term supposedly implies it.
• Changing terms mid-project without telling the client.
• Billing for work that was never approved, then blaming the terms when the client stalls.
• Assuming an app will collect the money for you — Invoice Maker creates and shares PDFs and tracks status, but payment still happens between you and your client.
• Marking a job finished before you have recorded the payment against the invoice.

None of this is complicated, but it only works if it is consistent. Write your terms once, save them in a template, and apply them to every invoice you send.
