Rojkhata
The daily ledger for transport operators: every taka in and out of a bus company, recorded from a phone, seen by the owner, in English and বাংলা.
The challenge
A bus company earns and spends in dozens of places a day: ticket counters, diesel pumps, tolls, crew allowances, repair shops, bKash and the bank. Expenses were written up days later or forgotten, receipts got lost, and the owner saw the true picture only when someone added up the paper khata at month end.
What we built
The person who spends the money records it on the spot, in four taps and an amount, with a receipt photo. Categories with a unit (litres, trips) work out quantity × rate for you. The owner opens to this month's profit, a 12-month trend and spending by category, all calculated live from the ledger. Cash, bank and mobile wallets each have a live balance. Owner, accountant and supervisor roles are enforced in the database. Nothing is erased: mistakes are reversed with a reason and a name. Amounts are stored as whole poisha, entries made with no signal upload when it returns, and a nightly off-site backup is restore-tested every month. It runs on free cloud tiers in the client's own accounts.
