Managing orders and sales becomes easier with OBook — a simple order manager for small business.

OBook keeps your orders, products and clients in one place, so you no longer have to hold everything in your head or in scattered notes. Everything you need is on your phone in a clear format — and the app works completely offline.

Key advantages of OBook:

Client base
Add a client once — with a photo, phone number, email and address — and their details are always at hand. You can even fill in a client card straight from your phone contacts. Each card shows the client's average order value and how much they still owe you.

Product catalog with stock control
Add a photo, name and price for each product. OBook tracks how many items you have in stock and how many are reserved in active orders, so you never oversell.

Orders in a few taps
Create an order in seconds: pick a client from your base, attach products, set the delivery date and address. No more manual math — quantities, prices and discounts (1%, 5%, 25% or your own) are calculated automatically. A repeat order is just a copy of the previous one.

Order calendar
See the whole month at a glance: every day shows how many orders are due on it, and overdue days are highlighted. Tap a day to see its orders. The "Today" button always brings you back to the current date.

Payments and debts
Record a prepayment, or mark an order as paid in one tap. The app works out how much the client has already paid and how much is still due, and flags orders with an outstanding balance so none of them slip through.

Order statuses, search and filters
Track every order from "In progress" to "Shipped" and "Completed", and filter by today, tomorrow or any date range. Search finds an order by client name, product name or comment.

Messages to clients
Ready-made texts — "your order is ready", "handed to delivery", "shipped", "thank you for your purchase" — are filled in with the order details. Send them to any messenger in two taps.

Documents and reports
Send a client the order details as text or as a tidy PDF sheet. Your order list and sales history export to Excel, CSV or PDF — handy for bookkeeping and for working on a computer. Your business name and phone number are printed at the top of every document.

Profit statistics
The History tab shows completed orders, a day-by-day profit chart, and rankings of your top products and top clients — so you always know what sells best.

Reminders
Every morning the app sends a short summary: how many orders are due today, for how much, and whether any are overdue. On Sunday evening you get the week's results.

Backup & restore
Keep your data safe: export the whole database with photos to a file or Google Drive and restore it on any device.

The app also lets you:
• add photos of clients and products
• fill in client details from your phone book
• add a delivery address and comments to an order
• set the date an order is due
• view order history and statistics
• work fully offline — no internet connection required

Who OBook is for
Anyone who still tracks orders by hand — in a notebook, in notes or in a spreadsheet. Handmade makers, bakers, tailors, beauty professionals, florists and small online shops, sellers on social media and delivery services — everyone who needs simple tracking of orders, clients, stock and profit without a heavy CRM and without a mandatory subscription.
