Tankersathi keeps every order, every customer and every rupee outstanding on the phone already in your pocket. One number opens one business — and nobody else's.
Android only. Sign in with your phone number and a 6-digit PIN — no SMS, no waiting for an OTP that never arrives.
Flip back four months and total it yourself, or open the app: every customer with a balance floats to the top of the list, biggest first, each one labelled ₹4,800 pending. One tap calls them.
Revenue, expenses and profit for one day, one month or one whole year — pick the period and every number on the screen answers for that period, and nothing else.
A wet page, a lost book, a driver who took it home. Your records sit behind your phone number instead, and the app still shows them when the network is down.
Anyone with an outstanding balance sits above everyone else, biggest amount first, with the figure written next to their name. The call button is on the row — no digging for the number.
Open a customer and you get their whole history: total orders, what they've paid, what they haven't, when you last delivered — plus Call, WhatsApp and Navigate.
Most apps mix today, this month and all-time on one screen, which is exactly why the numbers stop being trustworthy. Here the heading says what you're looking at, and everything under it obeys.
The second the call ends, Tankersathi shows you his name and what he ordered last time. One tap and it's saved — no app to open, no form to fill, no unlocking the phone.
Regulars order in three words and hang up. By the time you've parked, filled the tanker and remembered, half of them are gone. So the app asks you right then.
Android 12 and above. Turn it on if you want it — the app works fine without it.
The app recognises the number against your own customer list, on your phone. Nothing is sent anywhere and no call log is opened.
Under a second later the prompt is on the screen with his name on it — over the lock screen, with the app's own chime, even if the call lasted four seconds.
Same amount, same address, dated today, marked unpaid. The prompt turns green and closes itself. Different this time? Open the form instead.
Print the sticker and put it on the back of the tanker. Anyone who sees it scans the code, fills their name, phone and address, and taps Book tanker.
The request lands in your inbox with a chime. You set the price and confirm — that's when it becomes a real order. The same link works on WhatsApp, so you can send it to a new apartment block instead of explaining the rate twice.
Overdue first, then today, then the rest. Mark delivered, record a payment or undo a mistake from the row itself.
Tick the contacts you already deliver to and import them in one go. Anyone already added is greyed out, so you can't double them up.
Fuel, salary, maintenance, repair, office, miscellaneous — with a photo of the slip, kept where only you can open it.
A red strip says you're offline and the last saved orders, customers and dues stay on the screen.
Worth knowing before you install anything that sits next to your business.
The app doesn't ask for call-log permission and never will. Android hands it the ringing number, it checks that number against your customer list on the phone, and that's the end of it — nothing leaves the device. You can also tell it to stay quiet for anyone who isn't your customer.
Your business is fenced off in the database itself, not just in the screens. Another supplier signing in sees nothing of yours — there is no query that would return it.
Android only today, one business per number, and a forgotten PIN is reset by a person on WhatsApp rather than a form. Small, but honest about it.
Type your phone number, choose six digits, type them twice, then name your business. That's the sign-up.
Import them from your phone book in one pass. Names and numbers are enough to start.
Keep the diary beside you for a week if you like. You'll stop reaching for it.
Your number, a six-digit PIN, and your customers imported from your phone book. About five minutes.
