What grocery store POS software should include
- Fast barcode sales and receipts
- Stock that rises with goods-in and falls with sales
- Expiry date and shelf location tracking
- Critical stock alerts and supplier orders
- Store credit ledger: customer balance, collections, prepayment
- Daily sales and profit report, best and worst sellers
- Cashier permissions and PIN security
The store credit ledger, digitised
The biggest headache of a neighbourhood market is the customer tab written in a notebook. The program keeps each customer's balance, purchase history and payments; who owes how much is visible with a single tap, and even if the notebook is lost, the records are not.
From a small shop to a multi-till market
For a single-till corner shop, Kassa is enough. Markets with several tills, warehouses or branches get a custom system with central stock, per-till reports and barcode sales software infrastructure; needs such as scales and weighed-product barcodes are added per project.

Frequently asked questions
What is grocery store software?
It is software that manages a market's sales, stock, expiry dates, suppliers and store credit in a single system.
Which program suits a corner shop?
For single-till corner shops and small markets, Kassa running on iPhone is a good fit; it needs no separate computer or installation.
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.
