You can add a Payin or Payout whenever you need to deposit or take money out of the drawer for transactions that do not pertain
to normal day to day sales. Payins/Payouts will be listed on the Z-report.
Go to Back Office > Configuration > Misc Settings > Payouts
You can create new payouts or delete ones that are in there. Clicking on the Attrib will change it from payout to payin. You can also have it so that when you do payouts /payins it can come out of the drawer or not come out of the drawer. You are limited to 18 unique entries for Payouts.
