Understand Your GST Math

For sales within the same state (like inside Tamil Nadu), the GST is divided into two halves. If the GST rate is 18%, it is split into 9% CGST (Central) and 9% SGST (State).

IGST (Integrated GST) is applied when goods are sold from one state to another (e.g., from Dharmapuri to Bangalore). The full percentage is applied under one head.

Retailers and wholesalers in Palacode and across India use RRRa ERP because it handles these complex splits automatically on every bill, keeping your accounts and inventory 100% accurate.
