Items, rates and buyer states
Enter your core lines with units and GST rates, then spend the time on the party list: agreed rate per buyer, credit limit, and — for anyone across the border in Bengal — the correct state so IGST applies automatically. That last field is easy to miss at setup and awkward to correct across a quarter of bills, so it is worth doing while our team is on the call with you.
Border-side trade and inter-state loads
Katihar's position means a share of the trade moves towards West Bengal, and an inter-state sale changes the tax treatment from CGST and SGST to IGST. That switch happens automatically once the buyer's state is set on the party, with the right state code printed on the invoice — so nobody has to remember which buyers are outside Bihar. The transport details needed for the e-way bill are on the same record.
A junction town and its trade
Katihar's position on the rail network makes it a distribution point as much as a retail market, and material dealers here supply outward across the district and towards the Bengal border. That gives the trade a wholesale character — buyers who take volume on terms, despatches by vehicle, and rates that differ from one regular customer to another rather than a single counter price.
Party-wise rates and long settlement
A shop supplying retailers rather than end users cannot run one price list. Each buyer has an agreed rate and an agreed settlement period, and keeping that in memory works until somebody else is billing. Holding the rate against the party means the right price appears whoever is at the counter, and holding the credit limit against them means a warning appears before the load leaves rather than after the balance has grown.
Setup and offline working
Thirty minutes on a call covers your details, your items with units, your parties and your bill format. Because power and network here are both unreliable, most shops use the Android app, which records everything offline and syncs when coverage returns — the counter never stops, and nothing is lost in a cut.
