Inputs: Item 1: 10 Hours Web Dev at ₹1,500/hr | Item 2: UI Design ₹10,000 | GST Rate = 18% (Intra-State)

  • Item 1 total = 10 × ₹1,500 = ₹15,000; Item 2 total = ₹10,000
  • Taxable Subtotal = ₹15,000 + ₹10,000 = ₹25,000
  • CGST (9%) = ₹2,250 | SGST (9%) = ₹2,250 | Total Tax = ₹4,500
  • Grand Invoice Total = ₹25,000 + ₹4,500 = ₹29,500

Summary: Taxable Subtotal = ₹25,000 | GST (18%) = ₹4,500 | Total Invoice Value = ₹29,500
