Hey @Karin van Dijk
For employees who gather Overtime, you can choose to pay it out or convert it to comp. time meaning it can be transferred to an absence balance of your choice. For more information on how to do this, here is our guide:
Alternatively you also have the option to manually adjust the balance by a certain number either plus or minus or you can set the balance to an exact value. Again here is our guide on how to do this:
For manual adjustments you can also put a note describing the reasoning for the adjustment, in your case you can put in that your employee bought the absence. If you have any follow up questions, I would be happy to answer them.
Best regards,
Conor
