Why should a grocery store POS run on a phone?
For a small business, a POS program that needs a separate computer, a separate barcode scanner and installation costs both money and counter space. In Kassa, the iPhone camera is the barcode scanner; you scan the product, see the total and take payment. Stock drops automatically with each sale, and you get an alert when a product hits its critical level.
During busy hours you can connect an external barcode scanner; with an ÖKC (fiscal cash register POS), thermal receipt printer and shelf label printer, it works just like a full supermarket checkout.
Store inventory software and store-credit ledger
Stock quantity, expiry date and shelf location are tracked for every product; stock is updated with incoming goods and reduced with sales. Store-credit customers' balances, points and prepayments are tracked on the same screen, so there's no need for a paper ledger.
AI-assisted analyses such as daily sales and profit reports, best-selling and non-selling products, shrinkage and price checks show the owner the real state of the business.
Barcode POS app: offline and secure
Sales don't stop when the internet goes down; records are kept on the phone and automatically backed up to the cloud when the connection returns. With owner and cashier roles, PIN app lock and permission restrictions, each user sees only their own work.
