Free Invoice Generator and Invoice Template
Add your business, the client, items with quantity and unit price, a discount, tax and payment details, and get a clean invoice with the total and the balance due worked out. Print it, save it as PDF or copy it into Google Docs or Word. Any currency, free, no sign-up, and nothing leaves your browser.
The invoice updates as you type. Write the quantity and the price of one unit: the amount, the discount, the tax and the total are calculated for you. Your draft is kept in this browser until you start over.
Invoice template: what to put on an invoice
| Part of the invoice | Example |
|---|---|
| Invoice number, date, due date | INV-0042, 14 days |
| Your business, tax ID, the client | Acme → Globex |
| Items: qty × unit price | 12 × 19.99 = 239.88 |
| Subtotal, discount, tax | −10%, VAT 20% |
| Total, paid, balance due | 2,851.07 |
How to get paid on time
Send the invoice as soon as the work is delivered, with a clear due date and every way to pay. Use the client’s purchase order number if they gave you one, and send it to the person who approves payments. A polite reminder a few days before the due date works better than a chase after it. Keep a copy of every invoice for your accounts.
From quote to invoice
Start with a quote: the quote generator uses the same items, discount and tax, so once the client accepts, fill in the same lines here and add the invoice number, the due date and your payment details. Check that the price leaves a profit with the margin calculator.
Frequently asked questions
What should an invoice include?
The word invoice and a unique invoice number, the invoice date and the due date, your business name, address and tax number if you have one, the client’s name and address, each item or service with the quantity, unit price and amount, the subtotal, any discount, the tax and the total, and how to pay you.
What is the difference between an invoice, a tax invoice and a proforma invoice?
An invoice asks the client to pay for goods or services you have delivered. A tax invoice is the name some countries, such as Australia, New Zealand and India, use for an invoice that shows the tax and lets a registered business claim it back. A proforma invoice is sent before the sale, as a quote in the form of an invoice, and is not a request for payment.
How do I number my invoices?
Give every invoice a unique number that follows on from the last one, for example INV-0001, INV-0002, INV-0003. You can add the year, such as 2026-001. Do not reuse or skip numbers: your accountant and the tax office need to see every invoice you have issued.
What payment terms should I use?
The most common terms are payment within 14 or 30 days of the invoice date. Write the due date on the invoice, say how to pay, for example a bank transfer with your account details or a payment link, and say what happens if payment is late, if your contract allows it.
How do I show a deposit or part payment?
Type the amount the client has already paid in Amount paid. The invoice shows the total, the amount paid and the balance due, so the client sees exactly what is left to pay.
Can I save the invoice as a PDF or use it in Google Docs or Word?
Yes. Print or save as PDF opens the print dialog of your browser: choose Save as PDF as the printer and email the file. Copy text puts the invoice on the clipboard as plain text, ready to paste into Google Docs, Word or an email.
Is my information stored or sent anywhere?
No. The invoice is built in your browser and the draft is saved only in this browser so you can come back to it. Nothing you type is sent to SalesBond or anyone else. Click Start over to clear it.
