Best for: Small shops that want zero commitment
Starting price: $0 per month (Free plan)
Free plan: Yes
Pros: Free plan with no monthly fee; No contract, cancel anytime
Cons: Flat rates get expensive at high volume; Hardware is sold separately
Square is the default starting point for a small retail shop. The Free plan costs $0 per month per location, with in-person card processing at 2.6% plus 15 cents and online processing at 3.3% plus 30 cents. Plus costs $49 per month per location with in-person processing at 2.5% plus 15 cents, and Premium costs $149 per month with 2.4% plus 15 cents. Plus and Premium both offer a 30-day trial. The free plan includes the full POS app, inventory, invoices and an online store, and Square absorbs chargeback costs, which no other major POS here matches.
The honest catch is rate rigidity. Flat rates do not move until the business clears about $250,000 a year in processing, when custom Pro pricing opens up, so a high-volume shop overpays compared with an interchange-plus quote. Hardware is also separate: a card reader costs $59, a terminal $299 and a full register $899. For a new or low-volume shop, though, Square is the lowest-commitment way to start.
