ChakkiBook — the hisaab book for your flour mill.
Customers, grinding orders and udhaar — all in one place. Record every order the moment the grain comes in, know exactly who owes what, and send the bill on WhatsApp before the customer walks out.
चक्की का हिसाब अब मोबाइल पर । ग्राहक, पिसाई और उधार का पूरा हिसाब।
The register is full. The udhaar isn't.
Most chakki owners still run on a paper register — and a paper register can't tell you who hasn't paid in three weeks, what you collected today, or which order is still waiting to be picked up.
Udhaar goes missing
Half-paid orders scribbled in a corner of the register get forgotten. Money that was earned never gets collected.
No idea what today made
Counting the day's earnings means flipping back through pages and adding it up by hand — if anyone does it at all.
Disputes over old orders
“Maine to de diya tha” — without a dated record and a shared bill, there's nothing to point at.
Everything the register did — and the parts it couldn't.
Built around how a chakki actually runs: grain comes in, it gets weighed, it gets ground, and some of the money comes back later.
Customer list
ग्राहकEvery customer with their phone number, searchable by name or number. Pick from your contacts or type it in.
Grinding orders
पिसाई के ऑर्डरRecord grain type, weight brought in, the drum deducted, flour given out and the grinding charge — with a ready-by date.
Udhaar tracking
उधारUnpaid, part-paid and paid — each order tagged so you always know the balance due against every customer.
Bill numbers that survive a reinstall
बिल नंबरEvery bill carries a running number. It is now stored on the server as well as the phone, so reinstalling the app no longer restarts the sequence and reissues a number that is already on paper in someone's shop.
WhatsApp & SMS bills
बिल भेजेंShare a bill or a payment reminder straight from the order — one tap, on the number already saved.
Daily, weekly, monthly summary
हिसाबMoney collected, udhaar still due, total business, collection rate and average order — without adding a single column by hand.
Your own grains & rates
अनाज और भावSet up the grains you grind and the rate for each, so every new order prices itself.
Big text. Plain words. Hindi on every screen.
Designed for a shop floor, not an office desk — large touch targets, high contrast, and a Devanagari line under every label so nobody needs training to use it.
Four steps, and your register is on your phone.

Download free from Google Play, create your account with your chakki's name, and you're in.
Add your grains and rates
Wheat, bajra, makka — whatever you grind, with the rate you charge for each.
Record orders as they come
Pick the customer, enter the weight and grain, note what's paid now, and save. Takes seconds.
Collect and review
Send reminders on WhatsApp for what's due, mark payments as they come in, and check the summary at closing time.
A product, not just a project.
ChakkiBook is designed, built and maintained in-house by Orange Essence Technologies — a cross-platform Flutter app on a Node.js and MySQL backend, with an on-device SQLite store and background sync so billing never stops when the network does.
If you run a small business that's still on a paper register, we can build the same thing for your trade.
Questions chakki owners ask
Is ChakkiBook free to use?
Yes. ChakkiBook is free to download on Google Play and you can start recording customers and grinding orders straight away.
Does it work in Hindi?
Yes. Every screen title and action label is bilingual — English with a Hindi line beneath it — so anyone at the mill can use it without training.
Can I send bills to customers?
Yes. Each order can be shared as a bill over WhatsApp or SMS directly from the transaction list, and you can send payment reminders the same way.
What if the internet goes down?
ChakkiBook keeps your records on the device and syncs to your account when a connection is available, so you can keep billing during a network drop.
Is there an iPhone version?
ChakkiBook is on Android today. An iOS build is on the roadmap — tell us if you'd like to know when it ships.
Can OET build something like this for my business?
Yes — that's our app development practice. ChakkiBook is one example of the kind of product we design and ship end to end. Start a conversation and tell us about your trade.
