What Is a GST Invoice Generator?
A GST invoice generator is an online tool that creates invoices which follow India's Goods and Services Tax invoicing rules — including GSTIN, HSN/SAC codes, invoice number, place of supply, and the correct CGST/SGST or IGST split. Instead of manually calculating tax in Excel or Word (where a single formula mistake can throw off your entire GST return), a free GST invoice generator does the math for you and produces a clean, print-ready invoice in seconds.
This matters more than it sounds: under GST law, every registered business must issue invoices in a specific format, and getting the CGST/SGST vs. IGST split wrong is one of the most common reasons small businesses run into mismatches during GST return filing.

FAQ
Frequently Asked Questions
Is this GST invoice generator really free?
Yes. This is a completely free GST invoice generator online — no signup, no hidden charges, and no limit on how many invoices you create or download.
Can I download the invoice as an image instead of PDF?
Yes. You can download as either PDF (for formal records) or PNG (a quick image, useful for sharing in chats or on social media).
Does this tool calculate CGST, SGST, and IGST automatically?
Yes. Based on your business’s state and your client’s place of supply, it automatically applies CGST + SGST for intra-state sales or IGST for inter-state sales — so you don’t have to calculate the split manually.
Is my business and client data safe?
Yes. All calculations and PDF generation happen entirely in your browser. Nothing you type is uploaded to a server — anything saved (like your business profile) stays only on your own device.
What is a GST invoice?
A GST invoice is a document a GST-registered business issues to a buyer, listing the goods or services sold, their value, and the GST charged. It’s required for the seller to remit tax correctly and for the buyer to claim input tax credit.
What is an HSN or SAC code?
HSN (Harmonized System of Nomenclature) codes classify goods, and SAC (Services Accounting Code) codes classify services, for GST purposes. Including the correct code on each invoice line item is required for GST return reporting.
