Open Invoice Generator is a free, browser-based invoice maker built for freelancers, independent contractors, and small businesses who need professional invoices without the overhead of expensive software.
Every popular invoice tool has the same playbook: give you a free plan, then lock the features you actually need behind a monthly subscription — watermarks on your PDFs, limits on how many clients you can have, paywalls on tax modes.
We built Open Invoice Generator because we believe a basic invoicing tool should be completely free, require no account, and respect your privacy.
The entire application runs in your browser. Your invoice data never touches our servers, because we don't have servers for your data. You can inspect our network tab — nothing goes out except loading the page itself and our cookie-free analytics.
The values that guide every decision we make.
Every invoice stays on your device. We architected the app so that sending data to a server is architecturally impossible — not just a promise.
No sign-up, no subscription, no onboarding. Open the app, create your invoice, download it. That's the entire flow.
VAT for UK & EU, sales tax for the US & Canada, GST, and 20+ currencies. RTL language support, and PayPal, SEPA & UPI QR codes.
Seven carefully designed templates — from clean minimal to bold editorial — so your invoice reflects your brand, not a generic spreadsheet.
Our PDF export renders exactly what you see in the preview. No layout shifts, no missing fonts, no surprises.
No watermarks. No usage limits. No hidden upsells on features you actually need. Free means free.
No signup. No credit card. Just open the app and start invoicing.
