How to Make an Invoice (Free, No Signup)

Every invoice, whether it is for $50 of design work or $5,000 of consulting, needs the same core fields. Leave one out and you create a question the client has to ask you — and every question delays payment.

• Your name or business name, and a way to contact you. If you are a sole trader, your own name is fine.
• The client's name or business name, and ideally the name of the person who approved the work.
• A unique invoice number, in a sequence you keep (INV-001, INV-002, and so on). Never reuse a number — it makes your records and the client's accounts a mess.
• The invoice date, and a separate due date. "Due on receipt" is vague; a real date is not.
• A clear description of the work or goods, item by item, not just "services rendered".
• The amount for each item, the subtotal, any tax, and the total due.
• How to pay: bank details, a payment link, or whatever method you actually accept.
• Payment terms in plain words — for example, "Payment due within 14 days of the invoice date."

Two fields people forget are worth adding even when they feel optional. The first is a short reference the client can quote when they pay, usually the invoice number itself — it is how their accounts team matches your payment to your invoice. The second is your tax or business identifier, if your country or your client requires one on invoices. I am not giving tax advice here: if you are unsure whether you need to charge or show tax, check your local rules or ask an accountant once, then reuse the same format every time.

Line items are where most invoices go wrong. One vague line — "website work, $800" — invites a dispute about what was included. Break the work into lines a client can recognise: "Homepage design, 1 page", "Contact form setup", "Two rounds of revisions". Each line gets a quantity, a rate, and an amount. If you charge by the hour, show hours times rate. If you charge a flat fee, say so on the line itself.

Then the maths, in this order, every time. First, add the line amounts to get the subtotal. Second, add tax if it applies, shown as its own line with the rate — for example, "Tax (10%): $80". Third, subtract any discount or deposit already paid, shown as its own line so the client can see it. The last number on the page is the total due, and it should be the biggest, clearest number on the invoice. A client who has to add the numbers up themselves will get it wrong or put it aside for later.

One practical rule: round sensibly and be consistent. If your lines come to $847.50, invoice $847.50 — do not round to $850 without saying so, because the client will compare your invoice against their purchase order and the difference becomes a query. And keep a copy of every invoice you send, in the same place, in number order. When a client asks "did you ever invoice us for that?" six months later, you want the answer in seconds, not after a search through your email.

Payment terms are not legal decoration — they are the single biggest lever on how fast you get paid. "Net 30" (payment within 30 days) is standard for larger companies, but for freelancers and small sellers it is often too long. I use 14 days as my default, and 7 days for smaller jobs where the client is a person rather than a company with a monthly payment run.

• State a due date, not just a term. "Due 12 November 2026" beats "Net 14" because nobody has to count.
• Ask for a deposit on larger jobs — 50% upfront is normal for custom work, and it filters out clients who were never going to pay.
• Offer one or two payment methods, not five. The more choices, the longer the decision.
• Add a late-payment note only if you mean to enforce it, and keep it polite: "A late fee of 1.5% per month may apply after the due date." An empty threat you never enforce teaches clients to ignore your terms.
• For repeat clients, keep the same terms every time. Changing terms invoice by invoice looks disorganised and invites negotiation.

If a client has their own payment cycle — many companies pay suppliers only once a month — ask about it before you start, not after you invoice. Sending an invoice on the 28th to a company that runs payments on the 15th means a 45-day wait no matter what your terms say. A one-line question up front saves a month of chasing.

Here is a complete example for a freelance designer, with every field filled in. Replace the details with your own and you have a working invoice.

Example: freelance design invoice

From: Sara Ahmed, freelance designer, sara@example.com. To: Bright Leaf Cafe, attention to the owner, Ali Khan. Invoice number: INV-014. Invoice date: 3 November 2026. Due date: 17 November 2026. Payment terms: payment due within 14 days of the invoice date, by bank transfer, quoting INV-014 as the reference.

Line 1: Menu design, 2 pages, flat fee, $300. Line 2: Social media graphics, 6 posts, $25 each, $150. Line 3: Two rounds of revisions, included in the flat fee, $0. Subtotal: $450. Tax: none charged. Deposit already paid: $100. Total due: $350. The note at the bottom reads: "Thank you for working with me. Please quote INV-014 when paying so your payment is matched straight away."

Notice what this example does well. The client can see exactly what they bought, the deposit is already deducted so there is no argument about it, the due date is a real date, and the payment reference is the invoice number. Nothing on this page needs a follow-up question, and that is the whole test of a good invoice: could a stranger in the client's accounts team pay it without emailing you first?

Send the invoice as a PDF, not as an editable document and not as a screenshot. A PDF cannot be quietly edited, it prints cleanly, and it looks professional. Send it to the person who approved the work and, if you know them, copy the accounts contact — the approver knows the work is done, the accounts team is the one who pays. Put the invoice number and the total in the email subject line, for example: "Invoice INV-014 — $350 due 17 November". It makes your invoice findable later, which matters more than a clever subject line.

If the due date passes, chase in stages. Day 1 after the due date: a short, friendly note — "Just checking you received invoice INV-014, due yesterday. Is there anything you need from me to get it paid?" Day 7: a firmer note, restating the amount, the due date, and the payment details. Day 14: a phone call, if you have the number, followed by the same request in writing. Most late payments are not malice — they are an invoice sitting in the wrong inbox, or a payment run that was missed. Assume that first, and you will keep the client while still getting paid.

One last habit that pays for itself: the moment a payment lands, mark the invoice paid, note the date, and thank the client in one line. Clients who are thanked promptly pay promptly next time. And if a client ever asks you to sign a document to confirm the work — a delivery note, a timesheet, or a contract — you can create a signature in your browser and attach it, rather than printing, signing, and scanning. Our free Digital Signature Generator does that without an account, and it pairs naturally with the invoice workflow above.

Do I need special software to make an invoice?

No. You need the fields listed above, a PDF, and a way to keep copies in order. A free browser tool is enough for most freelancers and small sellers, and it avoids a monthly subscription for something you send a few times a month.

What invoice number should I start with?

Start at INV-001 and go up by one for every invoice, including cancelled ones — mark a cancelled invoice as void rather than reusing its number. A clean sequence is what makes your records credible if they are ever checked.

Should I charge tax on my invoice?

It depends on where you are, what you sell, and whether you are registered for tax. Show tax as a separate line with the rate whenever you do charge it, and check your local rules or an accountant if you are unsure — this guide is not tax advice.

What if a client refuses to pay?

First, check the invoice itself: was the work described clearly, was the due date a real date, and did it go to the right person? Most disputes start there. If the invoice is sound, chase in writing in stages, keep every message, and for larger amounts consider a formal demand letter or local small-claims route before writing the amount off.
