Q: Is this GST invoice generator free?

Yes, it is completely free to use. You can generate unlimited invoices, preview them, and download them as PDF files without any registration or hidden fees.

Q: How do I know if I should charge IGST or CGST/SGST?

If your business and your client are in the same state, you must charge CGST and SGST (usually split 50-50 of the total GST rate). If they are in different states (or outside India), you must charge IGST. This tool auto-calculates this based on the states you select.

Q: What are the mandatory fields for a GST invoice?

A valid GST invoice must include: GSTIN of seller, Name/Address of seller and buyer, Unique Invoice Number, Date of Issue, HSN/SAC code, Description of goods/services, Quantity/Unit, Taxable Value, GST rate (CGST/SGST/IGST), and Total Value.

Q: Can I use this for export invoices?

Yes. For export of services, you usually select 'IGST' with a 0% rate (under LUT). Ensure you include your client's foreign address and the correct SAC code.

What does this GST invoice generator do?

This is a lightweight, free online GST invoice maker designed for Indian small businesses and freelancers. It automates the calculation of taxes (CGST, SGST, IGST) based on the seller and buyer locations, validates GSTIN formats, and generates a professional PDF invoice that you can send to your clients. It ensures you don't miss any mandatory fields required by the GST Act.

How is GST calculated on this invoice?

The tool uses the 'Place of Supply' rules. If both parties are in the same state, it splits the tax into CGST (Central) and SGST (State). If they are in different states, it applies IGST (Integrated). All tax amounts are calculated on the 'Taxable Value' (Qty × Rate) of each line item.

Formula: GST Amount = (Rate × Qty) × (GST % / 100)
Example: Intrastate Sale of ₹10,000 at 18% GST.
Result: CGST = ₹900, SGST = ₹900. Total Invoice = ₹11,800.

Who should use this tool?

This generator is perfect for independent freelancers, consultants, and service providers who are GST-registered and need to send monthly invoices to domestic or international clients. It's also great for B2B vendors who want a quick way to create a compliant draft before entering it into their accounting software like Tally or Zoho Books.

Worked Example: Billing a Client in another state

Suppose you are a graphic designer in Maharashtra billing a client in Karnataka for ₹50,000. Since this is an interstate transaction, you must select Karnataka as the Buyer State. The tool will automatically switch to IGST. At an 18% rate, the IGST will be ₹9,000, making your total invoice value ₹59,000. If the client was also in Maharashtra, you would have seen CGST (₹4,500) and SGST (₹4,500) instead.
