Why sell with a phone at a kiosk?
At a kiosk the counter is tight, customers can't be kept waiting, and most sales are a single item: a pack of cigarettes, a drink, a snack. Scanning barcodes with the phone camera instead of a computer, separate screen and wired scanner saves both space and cost; a Bluetooth scanner can be connected for busy hours.
Stock and profit in a kiosk POS app
For fast-moving products such as cigarettes, drinks and snacks, stock drops with every sale and you get an alert when an item runs low. At the end of the day, what you sold, what should be in the till and your profit are on one screen; even when the owner isn't in the shop, the report is visible on the phone.
Store credit and regular customers
Store credit for the kiosk's regular customers is kept in the program; balances, payments and past purchases are all recorded. For broader needs, see the grocery store program and quick sale program pages.

Frequently asked questions
Which program is best for a kiosk?
For single-counter kiosks, a program that runs on a phone, sells offline and keeps store credit is enough; Kassa is designed for exactly this need.
Is a barcode scanner required at a kiosk?
No. The iPhone camera reads barcodes; a Bluetooth barcode scanner can be connected for busy hours if desired.
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.
