As you can't deposit counterfeit money into your business bank account, it will result in a loss for your enterprise. If you are selling large-ticket items for cash, this can be particularly devastating for your business. Don't underestimate the cash flow problems resulting from accepting fake bills by mistake!Remember that some insurance policies may protect you from the cost of accepting counterfeit notes (as long as you follow procedures for detecting fake notes). This may be worth exploring if you accept cash payments in your business.
