Invoice Generator Tool

This professional invoicing solution offers a streamlined, browser-based invoice generator perfect for freelancers and small businesses who need to create polished invoices quickly and efficiently.

Built as a static web application with zero backend requirements, this tool runs entirely in the browser-meaning there are no servers to maintain, no APIs to manage, and absolutely no ongoing costs. You can host it anywhere from GitHub Pages to Netlify or Cloudflare Pages completely free of charge.

Create professional-looking invoices in under a minute without the hassle of creating accounts, managing subscriptions, or having your documents branded with someone else's logo. The intuitive interface allows you to easily add your business details and logo, client information, invoice numbers, issue and due dates, and select your preferred currency. Additional features include tax and discount calculations, shipping or extra fee options, customisable notes, and detailed payment terms.

The invoice builder includes everything you'd expect from premium software:

• Three elegant, print-optimised invoice templates (Modern, Minimal, and Bold)
• Real-time preview as you build your invoice
• One-click export to PDF, download, and print functionality
• Automatic invoice numbering
• Locally-saved presets for your company information, default tax rates, and currency
• Time-saving invoice duplication feature
• Comprehensive multi-currency support
• Customisable accent colours to match your brand
• Flexible line item management with sorting capabilities
• Optional footer fields for bank details, PayPal, Venmo, or other payment information
• Toggleable late-fee reminders or due-date banners rendered directly on the invoice

Privacy and accessibility are built into the core design-everything runs 100% client-side, ensuring your financial data never leaves your device. The application works offline after the initial load and is fully mobile-friendly, allowing you to create invoices on any device.

With the full source code and modification rights included, developers, independent business owners, and agencies will appreciate the flexibility to customise, rebrand, self-host, or even resell this solution. The straightforward static site architecture makes it simple to extend into a SaaS offering or integrate into a larger product suite.

This complete, ready-to-use invoicing product requires no technical expertise to deploy yet provides developers with all the tools needed for customisation.
