Magestore POS gives store owners the tools for effectively managing session (cash flow). The flow of cash in the POS is initiated by two things:
Money coming in, such as customers making purchases, or you put more money into the cash drawer.
Money going out, such as taking money out for business expenses (such as your inventory, staffing costs, operating bills, etc.) or order refunds.
At the end of every shift or day, the POS can generate a report to show all of these figures automatically.
