How InvoBill decides the tax split
- Same state (your company state and the customer's state): the tax shows as CGST + SGST.
- Different state: the tax shows as IGST.
- The customer's state comes from the party record. For a Cash Customer there is no state on file, so the split follows your own state.
Check before you save an invoice
- The customer's State and GSTIN are right on the party record. See Add customers and suppliers.
- Each product has the correct HSN / SAC Code and GST Rate (%). See Add products and services.
- On the invoice totals, look at Subtotal, Taxable Amount, the tax lines and the Total.
