Hi egbertbos,

Welcome to QBCommunity!

Your client's employee is able to take more leave than they have accumulated, without the need to create adjustments. In the Pay Run, select the employee and then select the Actions button. From there, select Take Leave, and enter in the hours of leave that they want to take off - in this case, a warning message will show up saying that "The employee is taking more leave than they have accrued". An earnings line will then be created for Leave Taken for the leave hours.

You can also preview the leave balances after this pay run gets finalised by selecting Leave Balances next to the Actions button.

If all the leave balances are correct, you can then finalise the pay run, and the new leave balance will reflect in the next pay run.

Here is a handy article that details this in a visual manner: https://support.yourpayroll.com.au/hc/en-au/articles/200035779-Leave-Entering-Leave-Taken

Hope this helps!
