Square

What it does

Square is a point-of-sale and payments ecosystem covering in-person card processing, hardware (Square Reader from $49, Stand at $149, Square Register from $799 or $39/month over 24 months), and an integrated suite spanning online store, invoicing, payroll, banking, and loyalty. Paid tiers (Plus at $49/month/location, Premium at $79/month/location) add advanced retail reporting, team management, and lower per-transaction rates. It's used across an unusually wide range of business types — retail shops, food trucks, pop-up markets, service businesses, and small restaurants — because the free tier and pay-as-you-go hardware make it viable at very low volume.

Who this helps

• New small-business owners who need a working POS on day one without a monthly software fee

• Mobile and pop-up sellers who need affordable, portable card-reading hardware

• Retailers who want POS data flowing automatically into payroll, banking, and marketing tools from one vendor

• Growing multi-location retailers ready to move to Plus/Premium for advanced reporting
