A cashier for grocery shops and supermarkets: the carton and the piece, weight, and an expiry date per batch.

One evening at the counter

F1 puts the cursor back in the scan box. A case of 12 bottles of water scans with its own barcode and deducts 12; the single bottle scans with its own and deducts 1; stock is kept in the base unit. A kilo and a quarter of tomatoes is typed as 1.25 at the price per kilo, because no scale is connected. A customer buying on credit is picked with F2 and the invoice posts to their account. Payment is cash with the change worked out, or card recorded as its own payment method, and the receipt is 80 mm paper from the print dialog or a WhatsApp link valid for a year.

What expires and what runs out

• Every delivery is recorded as a batch with its expiry date; the till suggests the nearest expiry, and an expired batch is flagged and can only be sold with an explicit confirmation, recorded under the name of whoever gave it
• A home-screen card for what expires within 30 days; the window can be changed in Settings
• A minimum per item: the low-stock list, a home-screen card, and a draft purchase order from the suggestion in one tap
• A supplier delivery received in parts; the payable is booked for what arrived each time
• Items import from a CSV file with Arabic or English headers; 500 items with their stock take about 6 seconds

Closing the day

A shift opens with a float and closes with a count; the difference between the counted and expected amounts is booked automatically, and the shift report shows sales and returns by payment method and compares revenue, invoice count and average ticket with the same weekday a week earlier. The shift cannot close until every sale saved on the device has uploaded.
