Overview
Square transformed small business payments when it launched its card reader in 2009. Today it's a full business platform — point-of-sale, online store, invoicing, payroll, banking, and inventory management. We used Square for three months running a pop-up retail operation and online store to evaluate the complete ecosystem.
Point of sale
Square's POS app is free to download and use. Accept payments via tap, chip, swipe, or QR code. The interface is intuitive — even first-time staff can start processing transactions in minutes. Hardware options include Square Terminal ($299), Square Stand ($149), and Square Register ($799).
Payment processing
In-person: 2.6% + 10¢ per tap/dip/swipe. Online: 2.9% + 30¢. Invoices: 3.3% + 30¢. No monthly fees, no contracts, no minimums. The transparent, flat-rate pricing is Square's biggest advantage for small businesses.
Online store
Square Online provides a free website builder with e-commerce functionality. Templates are clean and mobile-responsive. Paid plans ($29-79/month) remove branding and add features like abandoned cart recovery.
Invoicing
Square Invoices is free for unlimited invoices. Clients pay via credit card, ACH ($1 fee), or Cash App. Recurring invoices, payment schedules, and automatic reminders are included.
Banking
Square Banking offers a business checking account (no monthly fees), savings account (1.5% APY), and loans based on processing history. Instant deposits are available for 1.75%.
Pricing
Free POS app. Hardware: $149-$799. Processing: 2.6% + 10¢ in-person, 2.9% + 30¢ online. No monthly fees or contracts.
Our verdict
Square is the best all-in-one payment and business platform for small businesses, especially those with both in-person and online sales. The free POS, transparent pricing, and integrated ecosystem let you start accepting payments in minutes with no upfront cost.
