From what I’ve seen so far, there are a few commonly recommended options. The built-in Shopify POS seems like the easiest since everything syncs automatically, including inventory and customer data. But I’ve also come across third-party systems like Square, Lightspeed, and Clover that offer additional features depending on business needs.

The problem is, not every integration feels seamless. Some require apps, while others may not sync inventory in real time, which can create issues if you're managing multiple sales channels.

I’d really like to hear from people who have already tested different setups.

Which POS system are you currently using with Shopify?
How reliable is the integration in terms of syncing orders and inventory?
Would you recommend sticking with Shopify POS or going for a third-party solution?

Trying to make the right decision before investing time and money, so any real feedback would really help.
