Everything a shop needs, nothing it doesn't

Built for mini-marts, super shops, grocery, pharmacy counters, hardware stores, boutiques: any business that sells from shelves.

Point of sale that keeps up

Tap tiles or scan barcodes. Line and bill discounts, tax, walk-in or named customers, hold and resume bills, split payments across cash, card and mobile banking, quick-cash buttons, change due.

Receipts & invoices

80 mm and 58 mm thermal receipts printed silently to the till printer, plus clean A4 PDF invoices for customers who need one.

Products with photos

Upload a photo once and it appears on every till. Photos are auto-cropped and shrunk so they sync in seconds.

Inventory you can trust

Live stock on every sale, purchase and return. Reorder alerts, counted adjustments with reasons, stock value at cost and retail, a complete movement ledger.

Purchases & suppliers

Raise orders, receive stock, track what you owe each supplier and pay it down. Costs update automatically.

Customers & loyalty

Points on every purchase, credit sales with balance tracking, payment collection, full history per customer.

Returns done right

Partial or full returns straight from the invoice. Stock comes back, refunds are recorded, customer due drops.

Expenses & profit

Rent, salaries, utilities, anything. See gross and net profit for any date range, not just revenue.

Eight reports

Sales summary, product performance, category mix, profit & loss, stock valuation, customer insights, cashier performance, payment methods. Print or export every one.

Users & roles

Owner, Manager and Cashier with PIN sign-in. Cashiers see the till; owners see everything. PINs are stored hashed, never in plain text.

Works with your hardware

Any USB barcode scanner, any Windows printer, any PC from the last ten years. No special terminal to buy.

Dark or light, always glossy

A frameless window with glass panels, gradient accents and animated charts that looks like a product, not a spreadsheet.

Your Google Sheet is the database

Most shop software makes you rent a server or pay every month to keep your own sales data. UPTECH Smart Shop does neither.

Safe in your Google account. The sheet sits in your Drive, protected by your Google password and 2-step verification. You can open it any time and see every sale in plain cells.
Every PC, the same data. Tills, the back office and the owner's laptop all read and write the same sheet. Changes appear on the other screens within seconds.
Keeps working offline. Each PC holds a local copy. Internet drops? Sales continue and sync when it returns.
No domain, no hosting, no renewal. There is nothing to pay for and nothing that stops working when a bill is missed.
Yours forever. Export to Excel, build pivot tables, back up with one click. Your data never sits on someone else's server.

Good to know

Do I need to know anything about Google Sheets?

No. You create a blank sheet and paste one script. UPTECH Smart Shop creates every tab and column for you and keeps them in order. You never edit cells by hand (though you can look at them any time).

Is my data safe in a Google Sheet?

The sheet is private to your Google account, the same protection your Gmail has. The app talks to it through a script that only answers requests carrying your secret key. Nobody else, including us, can see it.

What if the internet goes down during trading?

Each PC keeps a local copy and queues its changes. Selling continues. When the connection returns, everything syncs automatically.

How many PCs can share one sheet?

As many as you like. Give each till its own terminal letter so invoice numbers never collide. Google's free quota comfortably covers a busy small shop.

Which printers and scanners work?

Any USB barcode scanner that types into a text box (that is nearly all of them) and any printer Windows can print to, including 80 mm and 58 mm thermal receipt printers.

Can I use my own currency and tax?

Yes. Currency symbol, default tax rate, payment methods, loyalty rules and receipt footer are all in Settings. The demo uses dollars; a Bangladeshi shop would set ৳ and add bKash and Nagad as payment methods in ten seconds.

Does it run on Mac or Linux?

Yes. The source includes build commands for macOS (dmg) and Linux (AppImage, deb). The browser build runs anywhere.

Can I change the look or add features?

Yes. The code is plain JavaScript with no framework and a guided codebase document. Adding a screen is one file plus one line.

Your shop deserves software this nice.
