GST Bill Generator: Create GST Bills Online Free (2026)

A GST bill generator saves you from calculating CGST, SGST, and IGST by hand every time you bill a customer. Here's how to create a GST-compliant bill online, free, in under a minute.

What a GST Bill Generator Should Do

• Calculate GST automatically based on the rate you set — no manual math
• Split tax correctly into CGST + SGST (same state) or IGST (inter-state)
• Include your GSTIN and the client's GSTIN if they're registered
• Add HSN codes (for goods) or SAC codes (for services)
• Produce a clean, print-ready PDF you can email, WhatsApp, or hand over in person

How to Create a GST Bill Online (Free, No Signup)

• Open Simple Invoice Maker — it works in any browser, no installation.
• Add your business details, including your GSTIN and logo.
• Add the customer's details — name, address, and GSTIN if applicable.
• List each item or service with quantity, rate, and HSN/SAC code.
• Set the GST rate — the generator calculates CGST+SGST or IGST and the total automatically, based on whether the transaction is within the same state or inter-state.
• Download the PDF bill — ready to send immediately.

GST Bill vs. a Regular Bill — What's Different

A GST bill (tax invoice) must show your GSTIN, the applicable HSN/SAC code, and the tax broken out as a separate line — not folded silently into the price. A regular bill or receipt doesn't need any of this. If you're GST-registered, every taxable sale needs a proper GST bill, not a plain receipt.

Who Uses a GST Bill Generator

• Retail shops billing walk-in customers with GST
• Freelancers and consultants invoicing GST-registered clients
• Wholesalers and distributors who need HSN-coded, multi-item bills
• Service providers — electricians, agencies, contractors — billing GST on completed work

Common GST Rates

Goods and services generally fall into GST slabs of 0%, 5%, 12%, 18%, or 28% depending on category — confirm the current rate for your specific HSN/SAC code, since rates are periodically revised.
