The ledger is a free add-on but has to be activated by our support. Contact us and we will happily do it.
Go to Settings > Add-ons > Ledger to fill in the information which needs to be saved in your ledger. You can choose from which fields the information should be collected.
In the left column you can choose to get information from your registers, e.g. Shifts, if you have various work places.
Fill in Default value in the right column as a back-up in case the shifts lack any important information.
Ticking the box "Allow external staff to sign in to the ledger" allows for non-Timezynk users to fill in their information on the spot and check in and/or out.
