GST Invoice Generator: Client-Side GST Invoices, No Subscriptions, $19 One-Time

#opensource #javascript #webdev #productivity

The Problem With GST Invoice Software

Most GST invoice generation tools like FreshBooks, QuickBooks, and Xero work on a subscription trap model:

  • Monthly bills — $15–$50/month just to generate simple invoices
  • Your data leaves your device — sensitive business information stored on third-party servers
  • Features locked behind paywalls — even basic GSTIN and HSN/SAC support requires higher tiers
  • No offline access — you need internet to generate invoices
  • Subscription treadmill — stop paying, stop accessing your own invoices

The Solution: 100% Browser-Based GST Invoice Generation

Meet GST Invoice Generator — a completely client-side GST invoice tool that runs in your browser. Your invoice data never leaves your device. Not for a second.

How It Works

GST Invoice Generator uses modern browser capabilities to create professional, GST-compliant invoices right in your browser. It handles:

  • Business details (name, address, GSTIN)
  • Customer details (name, address, GSTIN, place of supply)
  • Invoice metadata (number, date, due date)
  • Itemized list with HSN/SAC codes, descriptions, rates
  • Automatic GST calculation — detects intra-state (CGST + SGST) vs inter-state (IGST) supply
  • PDF export using pdf-lib — generates downloadable GST-compliant PDF invoices

Key Features

  • GSTIN support — dedicated fields for both business and customer GSTIN numbers

  • Auto GST calculation — 9% CGST + 9% SGST for intra-state, 18% IGST for inter-state
  • Place of supply selection — correctly determines tax type based on location
  • PDF export — one-click generation of downloadable GST-compliant PDFs
  • Zero uploads — everything happens in your browser, no server processing
  • No subscriptions — $19 one-time payment, forever yours

  • Supports all modern browsers — Chrome, Firefox, Safari, Edge

Pricing: Simple and Fair

$19.00 one-time — that's it. No monthly bills, no hidden fees, no expiring access.
