One home screen that surfaces what needs attention — money to collect, what is overdue, and the day's profit at a glance. Start here; the book sorts the rest.

One book for the whole business.
Invoices, baki, cash and stock — the things you track every morning and tally every night — kept together in one calm, private record.
Daily cashbook
Money in, money out, a running balance — open it each morning, close it each night.
Stock control
A simple stock book that flags what is running low and what is selling fast — straight from your real sales.
Customer baki ledger
A running balance for every customer, with statements you can share on WhatsApp in a tap.
Recurring invoices
Bills that repeat on their own — rent, tuition, subscriptions — sent without a reminder from you.
Estimates & quotations
Send a quote, then convert it to an invoice the moment it is accepted.
Backup & export
Your book lives on your own device, and a full export means it is always yours to take.
The invoice moment
Send a pro invoice in seconds. Share it on WhatsApp. Watch it get paid.
Build the bill, pick a premium design, and send it straight to your customer's chat. Log the bKash or Nagad payment and the very same document turns into a print-ready receipt — the whole job, from first line to settled, in one calm flow.

Smart, not showy
The tedious parts, done for you.
Ask a question, snap a bill, close out the day — and let BillBook do the counting. Every smart tool works from your own figures, in your own language.
-
Smart Helper
Ask about your business in plain words — in Bengali or English — and get the answer back from your own books.
-
Snap-a-bill
Photograph a supplier bill or receipt and it becomes an expense in your cashbook — no typing, no calculator.
-
Smart Scan
Photograph an invoice or a stock list and every line item is read and entered for you — just review and save.
-
Scan a statement
Snap a bank, bKash or Nagad statement, or a single-transaction screenshot, and the entries land straight in your cashbook.
-
Daily Close
One tap gives a clear end-of-day brief — what came in, what went out, where you stand — built only from today.
-
Smart stock
Watches your real sales to flag what to reorder and what is selling fast, so shelf calls come to you.
Every smart tool is optional. It organises and summarises your own numbers — it is not financial or tax advice, and it is not an NBR-certified record. Your figures stay on your device and only leave it — over a secure connection — the moment you ask a question or snap a bill. Never used for ads, never used to train models, never sold.

Speaks Bengali and English — properly.
Full Bengali and English — not a half-translated menu with English hiding underneath. Every screen is built in Bengali, so you and your staff work in whichever one feels natural.
- Invoices, receipts and statements render in the right script — the same care a banknote gets.
- Switch language anytime in Settings — your books come with you.
One engine · your taste
One app. Three themes.
This is the very same theming engine that powers BillBook — not a screenshot of it. Pick a theme and watch the whole page recolour, live. And the next time you open BillBook, it remembers exactly the look you chose.
Atelier opens dark and luxe · Aurora cools into glass · Ledger rises into daylight. Same data, three looks — your call.
Your books, in daylight.
Every taka of money in and money out, logged the moment it happens — with a guided end-of-day close. Open it each morning, settle it each night — and read exactly where the day stands.

Sample figures, for illustration.
From a blank screen to your first sent invoice
No setup wizard to dread, no manual to read. If you can keep a paper baki-khata, you already know how.
-
Set up your shop
Add your business name, logo and the look of your documents, then pick your language — Bengali or English. That is the whole setup.
-
Make your first invoice — or record a sale
Build a professional invoice in a few taps, or use Quick Add to log a sale, an expense or a cashbook entry on the spot.
-
Share it, and track the baki
Send the invoice on WhatsApp or imo, then record full or partial payments and watch the baki settle to zero. Show your bKash, Nagad or Bangla QR on every bill so money comes straight to you.
Everything stays on your device from the very first entry — no card, no account needed to begin.
Open the web appStart free. Upgrade only when it pays off.
Start free — real invoices, a real cashbook, real ledgers, right on your own phone. When you outgrow the free limits, simple paid plans add unlimited records, your own branding, cloud backup and a monthly allowance for Smart Helper.
The honest fine print.
Plain answers on offline use, who owns your data, devices, the free tier and what the smart features actually do.
Does it work without internet?
Yes — BillBook is offline-first. You can create invoices, take payments, run the cashbook and update stock with no signal at all.
If you turn on optional cloud backup, it simply syncs the next time you are back online. The connection is a convenience, never a requirement.
Is my data safe? Do you sell it or show ads?
Your records live on your own device by default — invoices, receipts, cashbook, orders, stock and your customer and supplier baki ledgers stay in the app on your phone. Nothing is uploaded unless you turn on optional cloud backup, and even then it is secured per user so only you can read it.
We never sell your data or your customers’ details, and we never show ads. You can export everything, or permanently delete it, at any time.
Does it work on a computer, or only on a phone?
Both. BillBook runs in any modern web browser on a desktop or laptop, and it can be installed as a standalone app. There is also an Android app.
To see the same records across a computer and a phone, turn on optional cloud backup and sync — by default each device keeps its own local book.
How do WhatsApp orders work?
You capture and track customer orders through to fulfilment in the Orders screen, and share polished invoices and statements straight to WhatsApp or imo.
So an order that arrives by message becomes a tracked entry, and the bill goes back the same way — in one place.
Is there a free version?
Yes. The Free plan covers a single business on one device and includes 10 invoices a month, 15 active orders, 40 cashbook entries a month and 2 report exports a month, plus a taster of 3 smart actions a month.
When you are ready for more, Premium removes those limits and adds your logo and branding, cloud backup and multi-device sync, invoice PDF customization, and up to 5 business profiles and 5 staff users. See the Pricing page for current subscription prices.
What languages does it support?
The entire app is available in বাংলা (Bengali) and English — fully translated, not a partial overlay.
You can switch languages in Settings, and your invoices and documents follow your choice.
Are the smart features private? What leaves my device?
The Smart Helper, Snap-a-bill and statement scanning are opt-in and require sign-in. They stay on your device until you use them.
When you ask the Helper a question or scan a bill, only what is needed — your typed question and the relevant figures, or the photo you scanned — is sent securely over HTTPS to the processing service to produce that answer or read that bill. It is never used for ads, never used to train models, and never sold. If you never use these features, none of that data leaves your device.
Is BillBook a payments app — does it touch my bank or card?
No. BillBook is a record-keeping tool, not a payments product. It never connects to a bank, card processor or payment gateway, and it never stores card or bank details.
To take money on bKash or Nagad you can show your own Bangla QR on every invoice — the payment goes straight to your account, with BillBook never in the middle. The app just keeps your business records clear and complete; moving the actual money stays between you and your customer.
Still wondering something? Open the web app and try it — nothing to install, no card needed.
