Short explanation
A cash register is the device (software + hardware) that records every sale, signs the transaction via a control unit and produces a receipt. It is mandatory for anyone selling for cash or card in Sweden.
What is included in a certified cash register?
- Manufacturer-declared software registered with Skatteverket.
- Connection to a certified control unit (CleanCash or equivalent).
- Receipt printout with date, time, VAT rates, total and control number.
- Z-report (daily close) and journal files archived for seven years.
- Support for returns, corrections and receipt copies within the rules.
Cash register vs. POS system
The cash register is the minimum requirement from Skatteverket. A POS system is the entire tool the restaurant works with — menu, ordering, KDS, inventory, reports, integrations and accounting. A modern POS like ViralConvert contains the cash register as one of many components.
When do you need a cash register?
As soon as you sell goods or services for cash or card in Sweden. There are exceptions for sales below 4 base amounts per year, but in practice every restaurant has the requirement from day one.
