Is invoiceKit really free? Are there any hidden costs?

Yes, invoiceKit is completely free with no hidden costs, no premium tiers, and no credit card required. You can create unlimited invoices and download them as PDFs at no cost, forever. Since all processing happens in your browser, our server costs are minimal, which is why we can offer this entirely for free.

How is invoiceKit different from other free invoice generators?

Most free invoice generators require you to create an account, limit how many invoices you can make, add large intrusive watermarks to your PDFs, or store your sensitive business data on their servers. invoiceKit works entirely in your browser, with no signup, no limits, and no data collection. Your client names, invoice amounts, and business details never leave your device.

Is my invoice data really private and secure?

Absolutely. All invoice creation happens entirely in your browser using JavaScript — your data never gets sent to our servers. We have no access to your company name, client details, invoice amounts, or any other business information. Your actual invoice data stays 100% private on your device.

Can I use invoiceKit for my freelance business or small company?

Yes! invoiceKit is designed for freelancers, contractors, consultants, and small businesses. The PDF invoices are professional, clean, and contain all the information your clients and tax authorities need — including invoice numbers, payment terms, line items, tax calculations, and your business details.

What currencies does the invoice generator support?

invoiceKit supports 25+ major world currencies including USD (US Dollar), GBP (British Pound), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), JPY (Japanese Yen), CHF (Swiss Franc), and many more. Each currency is formatted correctly with the proper symbol and decimal conventions.

Do the PDF invoices have watermarks?

There are no large or intrusive watermarks. Each invoice includes a small attribution line in the footer, "Generated by invoiceKit", so people know where it came from, but there are no promotional messages or anything that interferes with a professional invoice.

invoiceKit is free, has no ads, and doesn't ask for an account. That's a deliberate choice, not a trial version of something bigger. It costs us real money and time to keep it that way, and if invoiceKit has saved you some, a small donation helps keep it running.

Ongoing development
