Introduction: Demystifying Goods and Services Tax (GST) Invoicing
Goods and Services Tax (GST) is a comprehensive destination-based indirect tax system levied on the manufacture, sale, and consumption of goods and services across major global economies including India, Australia, Canada, Singapore, and New Zealand.
Issuing GST-compliant invoices is essential not only for fulfilling tax obligations but also for enabling your corporate clients to claim their eligible Input Tax Credit (ITC) without delay.

| GST Tax Component | Transaction Type | Tax Distribution Breakdown |

| CGST + SGST | Intra-State (Seller & Buyer in same state) | Split 50/50 between Central Government (CGST) and State Government (SGST). |
| IGST (Integrated GST) | Inter-State or International Sales | 100% levied as Integrated GST (IGST) to cover cross-border movement. |
