Items, buyer states and despatch
Enter your building and hardware lines with correct units. The setup that matters most in Guwahati is the party list: the correct state on every north-eastern buyer so IGST applies automatically, agreed rates, and credit limits. Make vehicle and receiver capture a habit on every challan from the first load, because that record is the whole protection on these runs.
Where the north-east buys its material
Almost everything the north-eastern states build with passes through Guwahati, and that shapes the trade completely. A load leaving Fancy Bazar or Athgaon may be headed twelve hours into Meghalaya, Nagaland or Arunachal, on a hired truck, to a buyer the dealer has never met in person.
The record is the whole protection
When goods travel that far to somebody you do not know, the challan is the only thing that exists if the load is questioned: vehicle number, driver, destination, date and the person who signed for it, held against the party and printable years later. That is why challan discipline matters more here than almost anywhere else in the country.
Inter-state despatch and the e-way bill
A despatch out of Assam means IGST rather than CGST and SGST, and the e-way bill figures have to be right or the truck stops. The tax treatment switches automatically once the buyer's state is set, and the value, HSN codes, buyer details and vehicle number the portal asks for are already on the invoice rather than being assembled at the gate.
Setup over a call
Thirty minutes covers your shop details and GSTIN, main items with their units, parties with opening balances and your bill format. Support afterwards runs in Hindi and English, and the app bills offline for the runs where coverage disappears.
