What is a POS system?

A POS system is what businessmen, merchants, managers use in managing a business/ retail shop/ restaurant. It monitors sales as it is being made, generates receipts, tracks stocks and inventory, manages employees and their shifts. I highly recommend the Loyverse POS for small to medium businesses. You can use their basic functionality to run your shop/ restaurant for free. You'll only have to when you want to use their advanced features.
