What we offer
Everything your business needs, in your pocket
No computer, no expensive till. Just the phone you already have.
Point of sale
Sell products and services, split a payment across cash, mobile money, card or bank, and print or share receipts. Open and close cash-register sessions per shift.
Works offline
Keep selling with no signal. Sales, invoices and stock changes are saved on the phone and upload by themselves when you are back online.
Stock control
Know what you have. Track stock levels, adjustments, damage and stock takes, with low-stock alerts before you run out.
Quotations & invoices
Send professional PDF quotations with your logo, turn them into invoices in one tap and see what each customer still owes.
Expenses
Record expenses by category with a photo of the receipt, so you see your real profit, not just your sales.
Reports
Daily summaries plus reports on sales, profit, stock and expenses. Export them to PDF or Excel for your accountant.
Team & roles
Add staff as cashier, manager, accountant or inventory officer. Everyone sees only what their job needs.
Rentals & suppliers
Hire out equipment with availability checks, deposits and returns. Manage suppliers, purchase orders and goods received.

About us
Made in Zambia, for the businesses that keep it running
Trade Sempai is built for shops, hardware stores, salons, boutiques, wholesalers and service businesses that want to know exactly what they sell, what they have in stock and what they are owed, without buying a computer or depending on a perfect internet connection.
We started with one question: why should good business tools only be for big companies? So we made one app that works on the phone you already carry, speaks Kwacha, and keeps working when the network does not.
Simple for everyone
If your cashier can use a phone, they can use Trade Sempai.
Offline first
Every screen keeps working without data. Syncing happens in the background.
Safe in the cloud
Your records upload to your business account, so a lost phone is not lost data.

Questions people ask
Does it work without internet?
Yes. You can sell, create quotations and invoices, record expenses and adjust stock with no connection. Everything uploads by itself when you are back online.
Which phones does it work on?
Android phones and tablets (Android 8 or newer), installed from this website until it arrives on Google Play. An iPhone version is not available yet.
Is it really free?
Yes. The Free plan has no time limit and covers up to 100 products, 50 customers and 5 quotations and 5 invoices a day. Upgrade only when your business needs more.
Can my staff use it on their own phones?
Yes, on the Basic and Premium plans. The owner adds each staff member with a role, so a cashier sees the till but not your profit.
Is my business data safe?
Your records travel over an encrypted connection to your business account, and only your team can see them. You can delete your account and all its data at any time.
What if I run out of quotations or invoices?
Buy a top-up inside the app for extra documents or a 7-day unlimited boost, or upgrade your plan.
