Frequently Asked Questions — GST Invoice

A GST invoice is a tax document issued by a GST-registered supplier at the time of sale. Any business registered under GST in India must issue a Tax Invoice for every taxable supply. Unregistered businesses issue a "Bill of Supply" instead (without charging GST).
CGST + SGST apply on intra-state sales (buyer and seller in the same state). Each is half the total GST rate — e.g., 18% GST = 9% CGST + 9% SGST. IGST applies on inter-state sales at the full rate (e.g., 18% IGST).
For ITC claims, the invoice must be from a GST-registered supplier with a valid GSTIN, and it must appear in GSTR-2B. This generator helps create basic invoices. For full ITC compliance and auto GSTR-1 filing, use Khata Billing.
A valid GST invoice must include: supplier name & GSTIN, invoice number & date, customer name & address, product/service description with HSN/SAC code, quantity, taxable value, GST rate & amount (CGST/SGST or IGST), and total payable amount.
