Clover

Clover is a strong pick for brick-and-mortar retailers and restaurants that want an all-in-one POS with solid hardware options and built-in payment processing.

The biggest pro is how much is included out of the box — payments, reporting, staff tools, and loyalty. The main downside is that pricing is complex and varies by business type, reseller, and hardware choice, so your total monthly cost can be hard to pin down before you talk to sales.
