Processing cash is by far >not free<! In fact, it costs a lot of money due to all the things involved (counting/collection/recycling etc). Anf it inwolves additional risks for the handling party.
People often say that but does the cost for handling cash really scale (even approximately) proportionally with the number of transactions or revenue?
Or is it more binary that you have to decide, you either handle any cash and have the cost associated with it, or you refuse to take cash at all? If the latter is the case, then avoiding cash altogether seems somewhat unrealistic where I am from. And if it doesn't scale then it makes a lot of sense cost-wise to try to do as many of your transactions with cash as possible.
In the past I handled cash as an employee and as a volunteer. Like even a quiet night at a bar can sum up to a few thousand EUR.
Yes handling cash is not free. But compared to some charges or fees it's often quiet cheap.
Sure you need to think a head like how much small change money you will need or how much cash for change in general. You also need kind of routine and flow for counting and handling but even if I had to count up to 10k EUR in small bills t does not needed more then half an hour incl putting it into the safe or on the way home putting it into the banking machine... At least in Germany it's not that big of a deal breaker.
