The company name and organization number. b. The date and time when the report is generated. c. A running number from an unbroken ascending series. d. Information that it is a Z-day report. e.

Discounts should affect both the total amount and the VAT amount. If the total amount is reduced, the VAT amount should also be adjusted accordingly. Tips should not affect the VAT amount. Receipt printer on the Sunmi device. When printing a receipt copy, it should say "KOPIA" on the receipt, and it should only be possible to print once. Similarly, for returns, it should say "RETUR" on the receipt, and the relevant information should be sent to the admin panel. There should be an additional button in the payment options, named "SWISH". It is a payment method that allows customers to pay with their mobile phones. The cash register should only register the payment made with Swish, just like it would for cash payments. When selling a product, there should be an option to print a receipt. The system should ask if the customer wants to print a receipt or not. If the customer declines, the system should register the sale in the database as usual, but not print a receipt. There should be a button in the app where you can enter the starting cash amount for the day. This should allow you to record the amount of cash you have at the beginning of the day and any additional cash withdrawals or deposits made throughout the day. This information should only be recorded and displayed in the daily reports. Tips should be credited to the worker(based on username of pos), and it need to be showed on Z Rapport.
