BillBook Business

Bill customers in seconds, track who owes you, and know your cash every day. BillBook Business is a simple, offline-first invoice and billing app for small shops, traders, and service businesses — one app for your invoices, your credit ledger, your cashbook, and your stock.

Make a bill, hand over a receipt, record the cash or the credit, and watch your stock and balances stay in sync — all in one place, with no spreadsheets.

WHAT YOU CAN DO

• Create a clean, professional invoice, estimate, or quote with your shop name and logo, in your own currency. Share it on WhatsApp or save it as a PDF in one tap, or print a thermal receipt for fast counter sales.
• Receipt maker — turn any sale into a tidy receipt your customer can keep.
• Credit ledger — track who owes you and what you owe suppliers, see every outstanding balance at a glance, and send a polite payment reminder when a due date passes.
• Cashbook & expense tracker — record daily money in and money out, log expenses and owner withdrawals, and see your daily and monthly profit clearly.
• Stock & inventory management — add products, track quantity, scan barcodes, and get a low-stock alert before you run out.
• Orders, customers & reports — keep orders and customer details in one place, follow your daily sales, and export a clean monthly summary for your accountant.

WHY SHOP OWNERS CHOOSE BILLBOOK

A billing app that doubles as your everyday account book and cashbook — invoice, ledger, cash, and stock together, not four separate apps. No accounting knowledge needed, and you can set it up in minutes. Free to start, with an unlimited credit ledger and 10 invoices a month.

SCAN-TO-PAY WITH YOUR OWN QR

Add your own bank or wallet payment QR and it prints on every invoice. Your customer scans your QR and pays you directly through their own bank or wallet app. BillBook only prints the code — it never touches, holds or moves your money, and is not a bank or payment provider.

SMART FEATURES (a monthly allowance — free to try)

• Smart Helper — ask about your business in plain language and get a clear answer worked out from your own figures.
• Snap-a-bill — photograph a supplier bill and BillBook turns it into a draft expense you can review and edit.
• Smart stock — reorder and selling-fast alerts worked out from your real sales.
A small monthly allowance is shared across these tools at no cost; paid plans add a bigger allowance.

OPTIONAL TAX RATE — YOU STAY IN CONTROL

An optional tax-rate field adds a tax line to your invoice if your accountant advises one. BillBook is not a tax-filing or compliance service, is not certified by any tax authority, and your reports are not certified accounting — always share them with your accountant.

WORKS OFFLINE — YOUR DATA IS YOURS

Everything works with no internet, so a dropped signal never stops a sale. 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: 10 invoices, 40 cashbook entries and 2 report exports every month, 15 open orders at a time, and an unlimited credit ledger, stock list and supplier book. Your shop logo, every invoice design and PDF sharing are free, and so is cloud backup once you sign in. Premium adds unlimited invoices, cashbook entries, orders and exports, multi-device sync, workers on their own phones, bulk Excel or CSV import, a bigger monthly smart allowance, and the option to remove the small BillBook line at the foot of your invoices.

One simple invoice, billing, and bookkeeping app for your whole business. Your business book, made simple.

Recent changes:
Print receipts straight to a paired Bluetooth receipt printer — set it up in Settings → Receipt printer, then run a test print. The old “Send to printer app” route still works. The top bar and receipt settings now fit correctly on small screens and at large text sizes. Clearer results when a receipt is handed to your printer app, and repeated taps no longer start duplicate actions.
