If you’re looking just at the brick-and-mortar side of the business, it can seem like people only interact with your POS system at checkout. However, in reality, especially when its integrated with your online store, the POS system can affect the entire buyer experience. Your POS system is your source of truth for inventory management and keeping customers up to date with real-time information. And then if a customer needs to return or exchange something after checkout/delivery, your POS system can help manage those transactions as well.
