The point of sale (POS) system is a software application that allows a retail store to complete the cash register process, including the ability to print receipts, track inventory, and manage customer data.
A POS system can range from an inexpensive single-store solution to an enterprise-level system that can handle multiple locations or be integrated with other back-end systems. The most common features include:
Centralized reporting tools that allow users to track sales trends and inventory levels.
Inventory management tools that automate reordering processes and prevent overstocking or understocking of goods.
The ability to create custom discounts for specific products or groups of customers (i.e., senior citizens).
