Five kinds of credit tools, side by side
The table says who writes the entry down, whether the customer sees it, and who carries the credit.
| Kind | Who records the entry | Does the customer see each entry | Who carries the credit | Good for |
|---|---|---|---|---|
| Paper khata, slip book, Excel | The business | Only if you show or send it | The business | No phone, no signal, no training |
| Ledger apps: Khatabook, OkCredit | The business | By SMS or WhatsApp reminders; we did not find a customer app described on their pages | The business | Everyday khata, bills, many languages |
| Billing apps: Vyapar, myBillBook | The business | Bills and reminders on WhatsApp; myBillBook says it shares live ledgers | The business | GST invoices, stock, accounting |
| Pump software: GARRUDA, Petrosoft (YoungMinds), Petro Genius | Pump staff; GARRUDA starts from the customer's request for a vehicle | They list a customer app or portal | The pump | Pump back office; GARRUDA lists shifts, nozzle readings and Tally |
| Fuel cards and credit networks | The programme | Through its own app or portal | Depends on the programme | Cashless fuelling at the programme's own pumps |
| Khata Kavach | The nozzle man, after the transporter's request (by default) | Yes, in the transporter's own app, as soon as the pump's phone is online | The pump. It never lends or holds money | Regular transporters who fill diesel on credit |
Facts about Khatabook, OkCredit, Vyapar, myBillBook, GARRUDA, Petrosoft and Petro Genius from their own websites and app listings, checked on 19 October 2026. Tell us if anything has changed. The paper row describes general practice, and the fuel card row describes such programmes in general.
Where the other tools do more
- Khatabook and OkCredit have far larger download counts, shown on Google Play on 19 October 2026: 100M+ for Khatabook, 10M+ for OkCredit. Both have iPhone apps and many languages.
- Vyapar and myBillBook make GST invoices and e-way bills, and keep stock and accounts.
- Pump software covers the pump back office: GARRUDA lists shifts, nozzle readings and Tally.
Khata Kavach is new and is for petrol pumps only. Its bill is not a GST tax invoice, and it does not track stock.
Where Khata Kavach sits
It has two apps: the Pump app and the Transporter app. By default, the transporter sends a request before each credit fill, one per truck, in litres, in rupees or for a full tank. The nozzle man types the last 4 digits of the truck number and sees a green, amber or red light. By default a manager's PIN is needed past the limit, or the owner can choose cash only. The owner's Today screen lists the fills that look wrong from the last 7 days. A correction is a new line, so both sides see what changed.
The bill is a numbered bill on the pump's letterhead, with a UPI QR once you add your UPI ID, not a GST tax invoice. For the price, call us. Both apps open in the phone's browser today. Android apps are coming to Google Play.

Questions people ask
01Which khata app is right for my petrol pump?
GST invoices and accounts point to a billing app. A plain khata for a few credit customers points to a ledger app. Regular transporters who fill diesel on credit point to a shared credit book. You can use two together.
02Which kind of hisab kitab app should I use for udhar?
Start from what you need to see: your own totals, the transporter's view, a limit at the nozzle, or GST bills. Nine questions to ask are on our page on choosing a khata app.
03What is the difference between a ledger app and a shared credit book?
In a ledger app the pump types each entry. Some apps also send the customer a balance by SMS or share a ledger. Khatabook's and OkCredit's pages describe SMS or WhatsApp reminders to the customer, and we did not find a customer app described on their pages. In a shared credit book such as Khata Kavach the transporter has an app of his own, by default asks before the truck fills, and both sides see each line.
04Does Khata Kavach lend money or collect payments?
No. You set the limit for each transporter. Khata Kavach never lends and never holds money. The transporter pays you directly, and you record it.
