BillBook Business is a simple, offline-first business book for small shops and traders — one app for your invoices, your credit ledger, your cashbook and your stock. Pick your country once when you open it, and BillBook speaks your market: your currency, your language and your local scan-to-pay QR. Built for shopkeepers across South Asia, the Gulf and Southeast Asia.

WHAT YOU CAN DO

• Invoices & bills in seconds — a clean, professional invoice with your shop name and logo, in your own currency. Share it on WhatsApp or save it as a PDF in one tap.
• Credit ledger (khata / udhaar / baki / utang) — track who owes you and what you owe suppliers, see each balance, and send polite payment reminders in your own language.
• Cashbook — record daily income, expenses and owner's drawings, and see your daily and monthly profit at a glance.
• Stock & inventory — add products from a built-in catalogue of real local brands, track quantity, and get low-stock alerts before you run out.
• Orders, customers & reports — keep WhatsApp orders and customer details in one place, and export a clean monthly summary for your accountant.

SCAN-TO-PAY WITH YOUR OWN MERCHANT QR

Paste your own bank's merchant QR and it prints on every invoice. Your customer scans and pays, and the money goes straight to your account — BillBook never touches your money, and is not a bank or a payment provider. The right local QR appears for your country.

SMART FEATURES (a monthly allowance — free to try)

• Smart Helper — ask about your business in your own language and get a clear answer from your own figures.
• Snap-a-bill — photograph a supplier bill and BillBook reads it into an expense.
• Smart stock — reorder and selling-fast alerts worked out from your real sales.
Free to try with a small monthly allowance shared across these tools; paid plans add a bigger monthly allowance.

TAX-AWARE FIELDS — YOU STAY IN CONTROL

Optional tax and registration fields are formatted for your country and format-checked for your reference. BillBook is not a tax-filing or compliance service, is not certified by any tax authority, and your reports are not certified accounting — share them with your accountant.

WORKS OFFLINE — YOUR DATA IS YOURS

Everything works with no internet. Your data stays on your phone by default; cloud backup is optional and uses only your account email. No location or contacts are collected automatically. Export your full data anytime — nothing is ever locked in.

FREE TO START · PREMIUM WHEN YOU GROW

Start free. Premium adds unlimited invoices, your own branding on invoices (remove BillBook branding), cloud backup and multi-device sync, and a bigger monthly smart allowance.

One app, your whole country list inside it. Your business book, made simple.
