Offline Invoice & Quote Generator | HTML App, PDF Export, No Subscription

Description

The Growtoria invoice generator is a real invoicing app in a single file — fill in your details, auto-calculate totals and tax, and export a branded PDF, fully offline.

Tired of clunky invoice templates and monthly invoicing subscriptions? This is a real invoicing app in a single file – download one .html, open it in any browser, and it just works. Offline. No login, no account, no subscription.

Works on Mac & Windows – Chrome, Safari, Edge or Firefox. Nothing to install, no sign-up, no internet required.

WHAT IT IS: A standalone invoice and quote generator (a downloadable .html file – not a spreadsheet, not a printable template). Fill in your business, client and line items; it auto-calculates totals and tax and exports a clean, branded PDF.

What It Does

• Invoices AND quotes – switch with one toggle
• One-click branded PDF export (your business name + logo)
• Auto subtotal, tax and total as you type
• 5 currencies: $ USD, GBP, EUR, CAD, AUD
• Save clients and documents locally, reload anytime
• Add your logo for a professional look

RUNS OFFLINE – YOUR DATA STAYS PRIVATE: Unlike cloud spreadsheets and web apps, everything runs in your browser, on your device. No sign-up, no server, no internet. Your client and financial data never leaves your computer.

PERFECT FOR: Freelancers (designers, writers, developers), agencies, consultants, studios and contractors – anyone who bills clients and doesn't want another monthly subscription.
