cash memo can have a simple workflow
starting with cash memo, i am suggesting that instead of showing "cash received" in the cash memo, during entry creation time, we have an option to have a cashier management system where one person would take the order ( entry creation from pos) and the next person would receive cash and print invoice. Each of the two people would be only allowed their specific jobs so that no person can create the entire invoice and cash receipt and inventory all by themselves.
