What Is an Invoice Generator?
An invoice is the official document that records a sale and requests payment from your client or customer. Whether you run a small business, work as a freelancer, manage an e-commerce store, or handle accounts for a larger company, a clear and professional invoice speeds up payment, reduces disputes, and keeps your books in order.
Our free Invoice Generator at Tools Galaxio lets you build a polished, print-ready invoice in under two minutes — entirely in your browser. No software to install, no subscriptions, and no watermarks. Add your logo, enter sender and recipient details, list products or services with quantities and tax, choose your currency, set payment terms, and download a clean PDF with one click.
Unlike static Word or Excel templates, this tool auto-calculates line subtotals, tax, and the invoice total in real time. It is designed for everyday billing — from one-off freelance projects to recurring client work — without the complexity of export customs fields found on proforma invoices.
Everything You Need in an Invoice Generator
1. Branded Logo Upload
Upload your company logo and it appears in the PDF header alongside your business name. A branded invoice looks more credible and helps clients recognise your business instantly.
2. Sender & Recipient Details
Fill in complete From (your business) and To (client) information through easy modal forms. Capture company name, contact person, address, city, country, phone, email, and website for the sender; and first name, last name, business name, email, phone, and full address for the recipient.
3. Invoice Number, Issue Date & Due Date
Set a unique invoice number, the date the invoice was issued, and a payment due date. These three fields are essential for tracking accounts receivable and following up on overdue payments.
4. Flexible Line Items
Add unlimited products or services. Each line includes product name, optional description, quantity, unit price, per-line tax rate, and an auto-calculated subtotal. Add or remove rows instantly as your invoice grows.
5. Multi-Currency Support
Invoice in USD, EUR, GBP, INR, PKR, AED, CAD, AUD, and dozens more global currencies. Switch currency from the summary panel and all totals update with the correct symbol automatically.
6. Auto-Calculated Tax & Totals
Apply tax on a per-line-item basis. The invoice summary block calculates Subtotal, Tax, and Total in real time — no manual spreadsheet formulas required.
7. Payment Terms & Notes
Add custom invoice terms at the bottom of the document — payment instructions, bank account details, late-fee policies, or delivery notes. Keep your billing expectations clear from the start.
8. Instant PDF Download
Click one button and download a fully formatted, print-ready PDF. No email required, no account, no watermark. The PDF is ready to attach to an email, upload to accounting software, or file for your records.

Frequently Asked Questions
What is an invoice?
An invoice is a commercial document issued by a seller to a buyer that lists goods or services provided, quantities, prices, taxes, and the total amount due. It serves as both a record of the transaction and a formal request for payment.
Is this invoice generator really free?
Yes, completely free. Our Invoice Generator on Tools Galaxio requires no sign-up, no account, and no payment. Fill in your details, generate the PDF, and download it — all within your browser session. There are no watermarks on the downloaded PDF.
Does the tool save my data or store my invoice?
No. All processing happens locally in your browser. Your data is never sent to a server or stored anywhere. Once you close the tab or start a new session, the form resets. This makes it a privacy-first tool for sensitive business data.
Can I add my company logo to the invoice?
Yes. Upload your company logo image and it will appear in the header of the invoice PDF alongside your business name and contact details.
What currencies does the invoice generator support?
The tool supports dozens of global currencies including USD, EUR, GBP, INR, PKR, AED, CAD, AUD, SGD, MYR, and many more. The currency symbol updates automatically across all totals when you switch.
How many line items can I add?
There is no limit to the number of line items. Add as many products or services as needed using the "Add new invoice item" button. Each row supports name, description, quantity, unit price, and tax rate.
What is the difference between an invoice and a proforma invoice?
An invoice is issued after a sale is completed and creates a payment obligation. A proforma invoice is issued before the sale is confirmed as an estimate or quote — it is not legally binding. Use our Proforma Invoice Generator for pre-sale and export scenarios.
Can I use this for freelance work?
Absolutely. Freelancers, consultants, designers, developers, and writers use this tool daily to bill clients. Add your name or business as the sender, list your services as line items, set a due date, and download the PDF to email to your client.
How do I choose an invoice number?
Use a consistent, sequential numbering system such as INV-0001, INV-0002, and so on. If you need to generate a batch of numbers at once, use our Invoice Number Generator with sequential, date-based, or client-code formats.
Does this work on mobile devices?
Yes. The invoice generator is fully responsive and works on smartphones and tablets. You can fill in all fields, add line items, and download the PDF on mobile.
