This free invoice generator lets any freelancer or small business create a clean, professional invoice and download it as a PDF in a couple of minutes — no signup, no account, and no watermark. Whether you bill by the hour, by the project, per word, or per delivery, you fill in a simple form, watch the invoice build in a live preview, and export a polished document you own completely. Everything runs in your browser: your logo, your business details, and your client information never leave your device.

Freelancers across every field use it — developers and sysadmins, designers and video editors, writers and translators, consultants and virtual assistants. The invoice generator pdf output includes your company logo in the header, an itemised line-items table with quantity, unit and rate, automatic subtotal, discount and tax calculations, unlimited custom fields for things like PO numbers or contract references, and dedicated sections for payment instructions and terms. It supports eight major currencies so it works for freelance markets worldwide.

Unlike most tools that gate PDF export behind a paywall or stamp a watermark on your document, this online invoice maker free gives you the finished file with nothing added. Your business details are saved locally in your browser so you never have to retype them, invoice numbers auto-increment for you, and you can save a reusable template. The result is a consistent, branded invoice that helps you look professional and get paid faster.

What a Professional Invoice Should Include

A professional tax invoice needs to make three things unmistakable: who is billing whom, what is being charged for, and how and when to pay. The header carries your business identity — logo, name and contact details — alongside a clear "INVOICE" label, a unique invoice number, the issue date and the due date. The "Bill To" block identifies the client, including their tax ID where local rules require both parties' numbers. The heart of the document is the line-items table: each row lists a description, quantity, unit and rate, with the total calculated for you. Below it, the subtotal, any discount, and any tax or VAT roll up into a bold grand total. Clear payment terms — your bank, UPI, or PayPal details plus a due date and late-payment note — remove friction and help you get paid on time. Custom fields let you attach purchase-order numbers, contract IDs or project codes that a client's accounts department may need before releasing payment. Exporting to PDF invoice format preserves this layout exactly on any device.

Invoice Generator — Frequently Asked Questions

What is a free invoice generator?
A free invoice generator is a tool that lets you create a professional invoice by filling in a form, then download it — usually as a PDF — at no cost. This one runs entirely in your browser: you enter your business and client details, add line items, and export a clean PDF with no signup, no watermark and no data ever sent to a server.
How to create a professional invoice?
Add your business name, contact details and logo; identify the client; give the invoice a unique number and a due date; list each service with its quantity and rate; add any discount or tax; and include clear payment instructions. This tool structures all of that for you and shows a live preview, so you simply fill in the fields and click Generate & Download PDF.
What should an invoice include?
A complete invoice includes your business name and contact details, the client’s details, a unique invoice number, the invoice and due dates, an itemised list of goods or services with quantities and rates, the subtotal, any discount and tax, the total amount due, and payment instructions. Depending on your country you may also need one or both parties’ tax or VAT identification numbers.
How to add tax to an invoice?
Enter your applicable tax, VAT or GST rate in the Tax field and the tool multiplies it against the subtotal (after any discount) and adds it to the total automatically, showing a line such as "Tax (18%)". The tax rate you enter is used purely for the calculation shown — always confirm the correct rate and rules with a qualified accountant or your local tax authority.
What is an invoice number?
An invoice number is a unique identifier you assign to each invoice so you and your client can reference it in payments, records and correspondence. This generator creates one automatically from the first letters of your company name plus an auto-incrementing sequence (for example TECH-001, then TECH-002), and you can edit it to match your own numbering scheme.
Can I use this invoice generator for free?
Yes. The tool is completely free with no account, no subscription and no usage limits. There is no watermark on the generated PDF and you own the invoices you create in full. It is supported by unobtrusive ads rather than charging you.
What currencies does this support?
You can bill in US dollars (USD $), euros (EUR €), British pounds (GBP £), Indian rupees (INR ₹), Australian dollars (AUD A$), Canadian dollars (CAD C$), Singapore dollars (SGD S$) and UAE dirhams (AED). The chosen symbol is shown throughout the invoice and in every calculated total.
How to add my company logo to an invoice?
Click the logo upload button and choose a PNG, JPG, WEBP or SVG file up to 2MB. The logo previews immediately and is placed in the top-left of the PDF header. The image is processed entirely in your browser and stored only in your local browser storage — it is never uploaded to any server. Use only a logo you have the rights to use.
Is this invoice legally valid?
The tool produces a clear, itemised invoice document suitable for most freelance and small-business billing, but legal and tax requirements vary by country and situation. Requirements such as mandatory fields, tax registration numbers and retention rules differ between jurisdictions, so check that your invoice complies with your local regulations and consult a qualified accountant if you are unsure.
How to send an invoice to a client?
Generate and download the PDF, then attach it to an email to your client, or share it through your usual channel such as a client portal or messaging app. Because it is a standard PDF it opens on any device and preserves its formatting. Keep a copy for your own records and reference the invoice number when following up on payment.
