Free Invoice Generator: Create Professional Invoices Instantly
Getting paid is the lifeblood of any business, and a professional invoice is the first step in that process. This free invoice generator lets you create clean, detailed invoices in minutes without any software installation, account creation, or recurring fees. Everything works directly in your browser — your data never leaves your computer.
Whether you are a freelancer billing a client, a small business owner invoicing customers, or a contractor documenting project costs, this tool provides everything you need: line items with descriptions, quantities, and unit prices; automatic subtotal, tax, and discount calculations; and a print-ready format that you can save as PDF through your browser's print dialog.
Unlike many "free" invoice tools that require registration, limit the number of invoices you can create, or add watermarks to your documents, this generator has no restrictions whatsoever. Use it as many times as you want, for as many clients as you need.
How to Create a Professional Invoice
- Set your invoice number: Use a consistent numbering system (e.g., INV-001, INV-002) for easy tracking and tax compliance. The tool auto-generates a date-based number, but you can change it.
- Add your business details: Enter your company name, address, and email. This identifies you as the sender and gives the client your contact information.
- Add client details: Enter the client's company name, address, and email. This ensures the invoice is properly addressed and creates a clear record of who owes payment.
- Add line items: Click "Add Line Item" for each product or service. Enter a description, quantity, and unit price. The amount is calculated automatically.
- Set tax and discounts: Enter your applicable tax rate and any discount percentage. The tool calculates these automatically based on the subtotal.
- Generate and download: Click "Generate Invoice" to preview, then click "Print / Save as PDF" to export.
Invoice Best Practices
- Invoice immediately: Send invoices as soon as the work is completed or the product is delivered. Delays in invoicing lead to delays in payment.
- Be specific in descriptions: Instead of "consulting services," write "website redesign consultation — 4 hours, homepage and product page review." Clarity reduces disputes.
- Set clear payment terms: State exactly when payment is due (e.g., "Net 30 — due by May 15, 2026") and your preferred payment methods.
- Include all required information: Depending on your jurisdiction, invoices may need to include tax registration numbers, business registration numbers, or other legal identifiers.
- Follow up politely: Send a friendly reminder 7 days before the due date, on the due date, and 7 days after if payment has not been received.
- Keep records: Save PDF copies of all invoices for at least 7 years for tax purposes. Organize them by client and year.

How do I export my invoice to PDF?
After filling in your invoice details and clicking "Generate Invoice," click the "Print / Save as PDF" button. This opens your browser's print dialog. In the print dialog, change the destination to "Save as PDF" (instead of a printer). Click Save and choose where to save the file. The invoice is formatted with print-friendly CSS to ensure a clean, professional PDF output.
What information should an invoice include?
A professional invoice should include: (1) Invoice number for tracking, (2) Issue date and due date, (3) Your business name and contact info, (4) Client's name and contact info, (5) Itemized list of products/services with descriptions, quantities, and prices, (6) Subtotal, any discounts, applicable taxes, and total amount due, (7) Payment terms and accepted payment methods. This generator includes all these fields.
Is my data safe with this tool?
Absolutely. This invoice generator works entirely client-side in your web browser. No data is ever sent to any server, stored in any database, or shared with any third party. When you close the page, the data is gone. If you want to keep your invoice, save it as PDF before closing the page.
Can I customize the currency on my invoice?
Yes, you can select from common currencies including USD ($), EUR, GBP, THB, JPY, and more using the currency dropdown. The selected currency symbol will appear on your invoice next to all monetary amounts. You can also type a custom currency symbol if yours is not listed.
How should I number my invoices?
Invoice numbers should be unique and sequential for proper bookkeeping. Common formats include: simple sequential (001, 002, 003), date-based (INV-20260413-001), or client-based (CLIENT-001). This tool auto-generates a date-based invoice number, but you can change it to match your numbering system. Consistent invoice numbering is important for tax compliance and auditing.
What payment terms should I use?
Common payment terms include: Net 15 (payment due within 15 days), Net 30 (within 30 days, the most common), Net 60 (within 60 days, common for larger companies), Due on Receipt (payment due immediately), and 2/10 Net 30 (2% discount if paid within 10 days, otherwise due in 30). Choose terms based on your industry norms, your cash flow needs, and your relationship with the client.
Can I add my company logo to the invoice?
This simplified invoice generator focuses on clean, text-based invoices that work universally. For logos, we recommend generating the PDF first, then adding your logo using a free PDF editor. The clean layout ensures the invoice looks professional with or without a logo, and the text-based format means it prints and emails reliably on any device.
