Trade within a country: the services of wholesalers and retailers, itinerant and fixed shop retailers, departmental and chain stores, and how GST is charged.
| Sale within a state | CGST + SGST, each half of the GST rate |
| Sale from one state to another | IGST at the full rate |
| Price after a margin | price paid × (1 + margin% ÷ 100) |
| Consumer’s price through two traders | maker’s price × (1 + w ÷ 100) × (1 + r ÷ 100) |
| GST paid with input tax credit | GST% of the sale price − GST% of the purchase price |
| Departmental vs chain store | one central place, wide variety vs many places, one line; services many vs few; credit vs cash |
