Balance checks are a way of ensuring the correct balance is recorded in each tin.
A balance check should be run at the end of each shift
Simply launch the balance check from the left hand menu.
Select the house and tin you will be checking, and enter the exact amount of cash in that tin.
If the balance is what the system is expecting the balance will be saved, if however the balance is over / under the expected amount you will be prompted to recount the tin.
