GST or Goods and Services Tax was introduced in India on July 1, 2017, replacing a complex web of central and state taxes. For businesses, this meant a complete overhaul of how invoices are created and taxes are tracked.

Whether you run a small kirana store or a growing service business, understanding GST billing is essential for compliance and smooth operations.

Key Points

  • Supplier's name, address, and GSTIN
  • Unique invoice number and date
  • Customer's name, address, and GSTIN (for B2B)
  • HSN/SAC code for each item
  • Taxable value and applicable GST rate
  • Place of supply
  • Signature of the supplier

What Makes an Invoice 'GST Compliant'?

A GST-compliant invoice must include specific details as mandated by the GST Act. Missing any of these can result in rejection of input tax credit by your customers.

CGST, SGST and IGST — What's the Difference?

CGST (Central GST) and SGST (State GST) apply when buyer and seller are in the same state. IGST (Integrated GST) applies for inter-state transactions. Your billing software should automatically apply the correct tax type.
