Step-by-Step Guide to Creating GST Invoices

Step 1: Gather Required Information

Before creating your invoice, collect:

  • Your GSTIN and business details
  • Client's name, address, and GSTIN (if available)
  • Service description and amount
  • Appropriate SAC code
  • Place of supply (client's state)

Step 2: Determine GST Type

Based on your location and client's location:

  • CGST + SGST: When both you and client are in the same state
  • IGST: When you and client are in different states
  • CGST + SGST rates: Usually 9% + 9% = 18% total
  • IGST rate: Usually 18% for inter-state transactions

Step 3: Calculate Tax Amounts

For ₹10,000 service amount at 18% GST:

Same State (CGST + SGST):

  • Service Amount: ₹10,000
  • CGST @ 9%: ₹900
  • SGST @ 9%: ₹900
  • Total: ₹11,800

Different State (IGST):

  • Service Amount: ₹10,000
  • IGST @ 18%: ₹1,800
  • Total: ₹11,800

  • Inconsistent invoice numbering: Maintain sequential numbering
