One system for your till, stock, debts and books.

Stawi Biz is a business system for Tanzania. One sale at the till updates your stock, adjusts the customer’s balance if they bought on credit, sends the receipt to their WhatsApp, writes the accounting entry and updates your evening report. It runs on a phone, a computer or a browser, with support in Kiswahili.

Who it’s for
Shops and supermarkets, pharmacies, restaurants and bars, salons, hotels and lodges, clubs and gyms, and workshops and showrooms.
The problem it solves

Most shops don’t lose money because they aren’t selling. They lose it in the gaps: stock that walks, a sale cancelled after the customer paid, a debt nobody chased, and mobile money that never matched the till.

What it does
01
Receipts on WhatsApp

Every sale can send the customer a receipt on WhatsApp.

02
An evening report

Sales, profit and items to reorder update with every sale, so you know the day’s result before you get home.

03
Stock and debts

Stock drops with every sale and warns you when it runs low. Credit sales update the customer’s balance, and SMS reminders go out for overdue debts.

04
Selling without internet

The installed desktop till keeps selling when the internet is down. Phone sales queue up and sync later.

05
Staff control

Cancellations and refunds need a manager’s approval, and every stock change carries the name of the person who made it.

06
Mobile-money matching

M-Pesa, Tigo Pesa and Airtel Money payments are matched against sales, and anything that doesn’t match is listed for the shift.

07
Real books built in

Every sale posts to proper accounts. You get profit and loss, balance sheet, cash flow and a tax summary, and a month can be closed so it stops changing.

08
Tools for your kind of business

Restaurant tables and kitchen orders, pharmacy batches and expiry dates, salon bookings from a WhatsApp link, hotel rooms and guest bills.
