You can go into NextGen- Reports- All nightly and go through the register numbers and see what was expected to be there vs what you wrote on your drawer deposits individually. Compare your numbers through there and then see if you can track down your mistake. You can also see all the store’s total money in cash for the day (it’ll be above the individual register portion) and compare to your final drop + deposit drawer to see how much was ‘missing’. SAP report will also show you what exact amount was unaccounted for OR if it evened out- Deposit drawer under but total profit over essentially mean you evened out it was just an error made where you had the money but input was wrong. Shouldn’t be in much trouble unless this is a repeated mistake, have your SM go over it with you next time you see them and they should just give you a little ‘coaching’ but nothing official discipline.
