FAQ

Frequently Asked Questions about GST Invoices

What is a GST invoice generator?

A GST invoice generator is an online billing tool that helps businesses create invoices compliant with Goods and Services Tax (GST) regulations in India. It automatically includes mandatory fields like supplier and buyer GSTINs, sequential invoice numbers, HSN/SAC codes, place of supply, and accurate CGST, SGST, or IGST tax breakups.

How does InvoiceKhata determine CGST, SGST, or IGST?

InvoiceKhata automatically compares the supplier state code (from your GSTIN or business address) with the buyer state code (Place of Supply). If both are in the same state (intrastate), the GST amount is split equally into CGST (Central Tax) and SGST (State Tax). If they are in different states (interstate) or for exports, IGST (Integrated Tax) is applied at the full tax rate.

Is HSN/SAC code mandatory on GST invoices?

Yes, under GST Rule 46, businesses with annual turnover up to ₹5 Crores must mention at least 4-digit HSN codes on B2B invoices, while businesses above ₹5 Crores turnover must mention 6-digit HSN codes on all invoices. Service providers must include 6-digit SAC codes.

Can I create a GST invoice online without registering an account?

Yes! InvoiceKhata offers a guest mode where you can immediately create and download up to 3 GST-compliant PDF invoices per day without signing up or entering credit card details.

How can I add UPI QR code to my GST invoice?

When creating an invoice in InvoiceKhata, simply enter your UPI ID (e.g. yourname@okhdfcbank). The system will automatically render a scannable payment QR code directly on the downloaded PDF invoice.

What is the penalty for issuing an incorrect GST invoice in India?

Under Section 122 of the CGST Act, failing to issue a proper tax invoice or issuing an invoice with missing mandatory fields can attract a penalty of ₹10,000 or the amount of tax involved, whichever is higher. Using InvoiceKhata ensures all mandatory statutory fields are included automatically.
