Five features. That's all.

We solved the ones that actually matter. Nothing else.

Theft alerts on WhatsApp

When a driver claims more fuel than the tank holds, you get a message instantly. Before he leaves the pump.

Monthly fuel report

Every truck, every driver, every rupee. Takes 10 minutes to review. Not 3 days.

Cash advance tracking

Send advance via UPI. Every receipt auto-adjusts against it. Nothing gets lost or forgotten.

Route cost analysis

See the true fuel cost for every trip. Quote new jobs with confidence. Stop guessing.

Driver ranking

Who's honest, who's stealing, who needs a warning. Facts, not guesses. Kept private.

Your data, kept safe

Encrypted. Private. Never sold. You can export or delete everything anytime.

Questions

Everything you want to ask.

Do drivers need to download an app?
+
No. They already use WhatsApp every day. They send a photo of the receipt. That is the entire task.
What if the receipt is blurry or handwritten?
+
Our AI reads most receipts, including blurry and handwritten ones. If something can't be read, we flag it for you to check manually. Nothing slips through.
What happens after the free month if I don't pay?
+
Nothing bad. Your data is saved. You can come back any time. We just stop processing new receipts.
How is this different from BlackBuck?
+
BlackBuck is a marketplace — they find loads for your trucks. We are a financial tool — we watch where your fuel money goes. Very different problems.
Do my drivers need to know I'm watching?
+
Yes. Tell them. Most fleets see anomalies drop by 60% just because drivers know someone is checking. Honesty upfront works better than secrecy.
Can I start with just 5 trucks?
+
Yes. Start with 5, 10, or all your trucks. ₹499 per truck. No minimum. Add more anytime.
Is my data safe?
+
Yes. All data is encrypted. We never sell it. We never share it. You can export or delete everything anytime.
