Can I set up daily rentals?

Yes, it is supported. In the rules section click on the Configure time button. Then click Add period or open an existing period for editing. Specify the working hours to be a Whole day.

Next, open the existing step for editing and change to the Daily step. If there are no steps yet, then click Add step.

In the resource settings, set the Show only dates checkbox.

Another important parameter is the Include whole end day checkbox. If it is set, then when you choose period 01.01—02.01, it will be considered as 2 days. Otherwise, it will be 1 day.
