How to Generate a Free GST Invoice Online

Our free GST invoice generator is designed to be intuitive and fast for any Indian business — freelancers, MSMEs, or large enterprises. Follow these simple steps to create your compliant tax invoice:

Step 1: Enter Your Business Details

In the "Billed By" section, fill in your business name, GSTIN (if registered), address, and state. You can also upload your company logo for a professional touch.

Step 2: Enter Your Customer's Details

Fill in the "Billed To" section with your customer's name, GSTIN, address, and the "State of Supply." The tool will automatically determine whether to apply CGST+SGST (intra-state) or IGST (inter-state).

Step 3: Add Invoice Items

Click the "Add Item" button to add line items. For each item, enter the description, HSN/SAC code, quantity, rate, and applicable GST percentage. The tool instantly calculates the amount for each row and the grand total.

Step 4: Add Payment Details (Optional)

Optionally add your bank account details and UPI ID. If you enter a UPI ID, a QR code will be automatically generated on the invoice — making it easy for clients to pay instantly.

Step 5: Generate & Download

Click "Generate Invoice" to open the print dialog, or "Download PDF" to save a professional PDF copy. All your invoices are automatically saved to your browser's history for easy access.
