What does barcode POS software do?
Entering prices by hand is both slow and error-prone. With barcode sales, the product is scanned and the price and stock come from the system; checkout queues get shorter, and wrong prices and lost stock disappear. At the end of the day, how much each product sold, what should be in the till and your profit are all on one screen.
Which solution for which business?
- Corner shop, kiosk, small market: Kassa running on iPhone; no separate computer needed
- Market and deli: stock, suppliers and store credit with the grocery store program
- Kiosk and convenience kiosk: fast one-handed selling with the kiosk program
- Busy checkout: touchscreen product buttons with the quick sale program
- School and factory: card-based, prepaid-balance sales with the canteen program
- Store chain: multi-branch store program
Stock and reports in barcode sales
Stock increases when goods arrive and decreases on each sale; you get an alert for products at critical levels. Sales, stock, best-seller, warehouse and purchasing reports show the real state of the business in a few minutes. In multi-branch setups, inter-branch transfers and central reporting are set up.

Frequently asked questions
What is barcode POS software?
It is software that sells by scanning product barcodes, updates stock automatically, prints receipts and produces sales reports.
Can I sell with barcodes without a computer?
Yes. Kassa uses the iPhone camera as a barcode scanner; no separate computer is needed.
Can I connect a barcode scanner and receipt printer?
Yes. USB/Bluetooth barcode scanners, thermal receipt printers and label printers are supported; Kassa works alongside an ÖKC (Turkey's new-generation fiscal cash register POS).
Does selling stop when the internet goes down?
Kassa keeps selling without an internet connection and backs up to the cloud once the connection is back. Offline operation can also be built into custom projects.
Ready-made app or custom software?
Small businesses can try the ready-made Kassa app free for 14 days; businesses that need branches, warehouses, cards or integrations get custom-built software.
