Every day there has been activity at the cash register, a daily statement must be made. It is possible to make a daily statement the following day before opening hours, and Loomis—Pay supports backdating up to 3 days.
The Tax Administration was asked the question "Must daily Z-reports also be produced for cash registers that have not been used during the day?" and answered as follows:
No, if no registrations, drawer openings or other use have been made from the cash register in question, there is no requirement to produce a Z-report and make a daily statement for the cash register.
