Generate clear payment terms to include on your invoices.

When should the invoice be paid?
Include late fees?
Accepted payment methods?
Include cancellation policy?

Your payment terms

Payment is due within 30 days of invoice date (Net 30). A late fee of 1.5% per month will be applied to overdue invoices. Accepted payment methods: credit card, bank transfer, and PayPal. Cancellation policy: 50% refund available within 7 days of purchase.

Paste this on your invoices

Net 15 on a $4,000 invoice issued October 10 is a due date of October 25, not a sentence you explain later. The reminder uses that date. A term that never becomes a day is a term you cannot enforce.

Write payment terms a client can actually follow

Payment terms are the paragraph that stops “I thought I had 60 days” emails. They say when the money is due, how it should arrive, and what happens if it does not. Vague terms get vague payments. A sentence like “payable in a timely manner” is not a due date. Net 30 is a due date. Printing the calendar date next to Net 30 is even better.

Start with the due window. Due on receipt, Net 15, and Net 30 cover most freelance work. Longer windows are a gift you should give on purpose, not by accident. Then name the methods you actually accept. If you do not take checks, do not list checks. Clients will use the first method they see that is convenient for them, not for you.

Late fees belong in this block if you plan to charge them. A fee that appears only on a reminder looks like a surprise. Run the Late Fee Calculator so the percentage or flat amount in the terms matches the number you will put on a revised invoice. If you will not enforce the fee, leave it out. Empty threats train clients to ignore the rest of the paragraph too.

Deposits and cancellation rules are optional, and they are powerful on estimates as well as invoices. If work does not start until 40% is paid, say so. If a cancelled project keeps a portion of the deposit, say so. This generator is not a full contract. It is the payment paragraph you paste onto a PDF so the commercial terms are not hiding in a Slack thread.

Copy the result into the Free Invoice Generator, a Word template, or Incusia. Read it once. If a sentence does not match how you work, edit it. Saved default terms inside Incusia mean you do this once. The $9 Starter plan keeps that default, unlimited invoices, and a price lock for as long as the account stays open.

What a term is worth once it is on the invoice

A payment term that lives in your notes and not on the $4,000 invoice is a term the client can say they never saw. Net 15 printed under the total, with October 25 as the date, is the version you can point to. The wording generator is for that sentence. The date is what the sentence becomes.

The term is on the invoice the client receives, not in a message they can lose. Net 15 on a $4,000 bill is a date.

What happens the day after that date

On October 26 the $4,000 is overdue because the term said so, not because you decided to be firmer. The reminder can cite the date that was already on the invoice. A new date invented in the chase is a different deal.

Once the written date passes, the invoice is overdue on its own. The term you pasted is the rule the reminder uses.

Frequently asked questions

Name the due window, the methods you actually accept, and what happens if payment slips. Due on receipt, Net 15, and Net 30 cover most freelance work. Print the calendar date next to Net 30 so nobody has to count. If you do not take checks, do not list checks. Late fees belong in this block only if you will charge them. Generate a paragraph here, read it once, and paste it onto the invoice. Vague terms like “payable in a timely manner” are not a due date. Clients follow the sentence you wrote, not the one you meant.

Net 30 means the full balance is due thirty calendar days after the invoice date, not thirty days after they open the email. Write the calendar due date on the PDF. If you invoice on the 4th, payment is due on the 4th of the next month unless a short month changes the day. A grace period sits after that date. It does not secretly rewrite Net 30 into Net 37 unless you said so. Use Net 30 for companies with a payables process. Use a shorter window when the invoice is your rent. This generator will print the structure. You still pick the window.

They are much easier to enforce when they were in the original written terms, the client had a chance to see them, and you actually invoiced on that basis. Terms you add after the work is done are a weaker story. Late fees, deposits, and pause-work clauses should live in the proposal and the invoice, not only in your head. Local law can limit interest. This page is a wording tool, not a lawyer. Put the paragraph on the PDF, keep a copy of what you sent, and follow the schedule you wrote. Process beats a speech in small claims.

Yes if you plan to charge them. A fee that appears only on a reminder looks like a surprise. Name the rate, when it starts, and whether there is grace. Run the late fee calculator so the percentage in the terms matches the number you will put on a revised invoice. If you will not enforce the fee, leave it out. Empty threats train clients to ignore the rest of the paragraph too. Modest rates, 1% to 1.5% per month, are what most small businesses can explain without sounding theatrical. Write it once. Reuse it.

Due on receipt or Net 15 gets paid faster than Net 30 for individuals and tiny companies. Net 30 is a courtesy to clients with AP cycles, not a personality trait. Deposits before you start, especially 30% to 50% on larger gigs, prevent you from funding someone else’s cash flow. Put the methods on the invoice: bank transfer, card link, whatever you actually watch. This generator has templates you can adapt. The failure mode is rewriting terms from scratch every job until one ships with no due date. Save a default. Paste it every time.

Yes. Pick a template, adjust the sentences, copy the paragraph onto an invoice or estimate. No signup, nothing stored. You still need to paste it onto a real PDF. The terms do not collect money by themselves. They make follow-up boring and defensible. If you want those terms saved on every invoice automatically, Incusia can hold a default. Starter is $9 a month with the price locked. For the paragraph you need on this afternoon’s invoice, copy it from here and keep moving.

Payment terms are the money paragraph: when, how, and what if late. A contract can also cover scope, IP, cancellation, and liability. For a small invoice, clear terms on the PDF plus an email agreeing the work is often the whole paper trail. For a large project, you want both. Do not pretend a three-line Net 30 block is a master services agreement. Do not hide the due date only in a 12-page contract the client never opens. Put the commercial spine on the invoice. Use this generator for that spine.

Say the percent or amount, when it is due, and that work or a date hold starts after it clears. Add what happens if they cancel: keep a portion, refund the rest, or keep it all if you already bought materials. Invoice the deposit as a real PDF with its own number, not a vague Venmo request. Then invoice the balance on the schedule you named. This generator can produce a deposit paragraph you paste onto the estimate and the invoice so they match. Handshake work without a deposit is how photographers and trades fund other people’s events.

Or print the due date from the term, not from a later email

Net 15 on a $4,000 invoice is a calendar day. The reminder uses that day.
