Free Invoice Generator for Freelancers
Creating professional invoices shouldn't require expensive software or monthly subscriptions. WorkCalc's invoice generator lets you create, customize, and print invoices directly in your browser — completely free, with no watermarks or signup required.
What Makes a Good Invoice
A professional invoice should include: your business name and contact details, the client's information, a unique invoice number, the invoice date and due date, an itemized list of services with quantities and prices, applicable taxes, and the total amount due. Clear payment terms and a polite note can help you get paid faster.
100% Private
Unlike other invoice generators that require you to create an account and store your data on their servers, WorkCalc runs entirely in your browser. Your invoice data is never sent to any server. When you close the page, the data is gone. If you prefer a simple, privacy-respecting tool, this is it.
Frequently Asked Questions
Is this invoice generator really free?
Yes, completely free. No signup, no watermarks, no limits. Create as many invoices as you need.
How do I save as PDF?
Click the "Print / Save as PDF" button. A new window will open with a clean, formatted invoice. In the print dialog, select "Save as PDF" as your printer. This works in Chrome, Firefox, Safari, and Edge.
Is my data stored anywhere?
No. All data stays in your browser's memory and is never sent to any server. When you close the page, the data is gone. If you need to keep a record, print or save the invoice as PDF.
What payment terms should I use?
Common payment terms include "Net 30" (payment due within 30 days), "Net 15" (due within 15 days), or "Due on Receipt" (payment due immediately). For new clients, shorter terms are recommended. Always include late payment terms in your contract.
