I'm planning to set up POS systems in my coffee shop. I've been running the shop for a few years now, and I think it's time to streamline operations. I plan to use the POS system for several purposes: tracking sales, managing inventory, and speeding up the checkout process. Additionally, I want to have better insights into customer preferences and sales trends. There's so much out there, and I'm not sure where to start. Can anyone recommend a reliable POS system for a coffee shop? What features should I be looking for? Any advice would be greatly appreciated!
