Common Use Cases
Freelancers use this invoice generator to bill clients for hourly work or project deliverables without paying for subscription invoicing apps. Consultants create milestone-based invoices with custom tax rates for different jurisdictions. Small product businesses generate itemized sales receipts with volume discounts applied automatically. Students and side-project creators who need a quick, one-off invoice without signing up for QuickBooks or FreshBooks find this especially useful, since it costs nothing and stores no data on external servers.
Frequently Asked Questions
Is this invoice generator really free with no limits?
Yes. You can create unlimited invoices with unlimited line items at no cost. There is no account to create, no watermark on the PDF, and no feature gate. The tool runs entirely in your browser using JavaScript.
Is my invoice data private and secure?
Completely. Your business details, client information, and line items are stored only in your browser's local storage. Nothing is sent to any server. Even if you use the auto-save feature, the data stays on your device and can be cleared at any time.
Can I use this invoice generator for international clients?
Yes. The tool supports 7 currencies (USD, EUR, GBP, INR, CAD, AUD, JPY) with proper symbols. Select your currency from the dropdown and all amounts, including tax and discount calculations, will display in that currency on both the preview and the downloaded PDF.
How do I add tax or a discount to my invoice?
Below the line items, you will find a tax percentage field and a discount field. Enter your tax rate (e.g., 10 for 10%) and it will be applied to the subtotal. For discounts, enter a value and choose either percentage or fixed amount from the dropdown. Both are reflected in the total instantly.
Can I save my invoice and edit it later?
Yes. The tool auto-saves your draft to browser storage as you type. If you close the page and return later on the same device and browser, your invoice will be exactly where you left it. You can also click "Save Draft" to trigger a manual save, or "Clear" to start fresh.
