It depends the kind of employees you have in your business that will make them to cheat freely and get away in your business because there are some technology security you will fix in your business to catch cheaters in your business to boost your income, you can make use of small security lights all over your business inside and outside your business and it will help you to eliminate cheaters from your business because any single cheating that may come up in the business it will be display publicly for the security personnel to be alert, allow sales boys and girls to your business account is wrong but you can allow them to deposit funds into the business account, but don't allow them to have access to the code or password to the account because they can be tempted to do what they have not done before to the account.
Good point, as per technology there are security system that you can attach to your business and allow you to monitor what your employee are doing during business hours, though it can help in some aspects but similar to what you mentioned if the personel have that access with the money or the value products they can be tempted to do something bad, it's going to be a good help in both your business and for those people who are working with you, limit or be present and do those important role.
