Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
You should conduct an investigation with the cashier/s of your business regarding the true ownership of the over’s (extra monies’). If you are certain that the over’s do not belong to your business, then such monies should be returned to their original owner’s. However, If one cannot find the original owners, then such monies’ should be dispensed in charity (Sadaqah).
And Allah Ta’āla Knows Best
