All-in-one payments and POS platform popular with small and mid-sized in-person businesses, with online tools via Square Online.
Quick Answer
Square is a strong fit for retail shops, restaurants, cafes, salons, and service businesses that want an all-in-one in-person POS with free software and online selling capabilities. Its flat-rate pricing requires no monthly fee on the base plan and is straightforward for new businesses. Higher-volume merchants may find interchange-plus alternatives more cost-effective.

Guides to help you evaluate Square in context.
Key terms relevant to evaluating Square.
Square's point-of-sale software is free to download and use, with no monthly fee on its base plan. The free plan includes core POS features for retail, restaurants, and services. Square charges per transaction (flat-rate), and hardware such as card readers has separate costs. Optional premium software tiers with additional features carry a monthly fee. Verify current pricing directly with Square.
Like other payment facilitators, Square may place temporary holds on funds or deactivate accounts if transactions appear unusual, if chargeback rates spike, or if the business category raises underwriting concerns. These holds can be disruptive. If your business processes large, irregular, or high-risk transactions, verify Square's policies in advance and have a contingency processor relationship.
Square for Restaurants is a purpose-built product within the Square ecosystem for food-service businesses. It includes table management, course firing, and kitchen display support. Restaurant-specific pricing and feature tiers vary from Square's standard POS. Verify current restaurant plan options and pricing directly with Square.
Yes. Square Online allows merchants to build an ecommerce presence connected to the same inventory and order management as their in-person POS. Square also offers checkout links, payment buttons, and integrations with WooCommerce and other platforms. Online transaction rates differ from in-person rates — verify current pricing directly.
Square maintains a public Prohibited Businesses policy. High-risk categories including firearms, adult content, certain financial services, and cannabis are typically restricted. As a payment facilitator, Square uses automated underwriting, which means merchants in borderline categories may face account reviews or closures without advance notice.

Payment Capability
Square documents a credit card surcharge feature for in-person POS and Invoices — currently in open beta — and Square states it is the seller's responsibility to verify compliance with local requirements.
Question to ask before applying:
"Which of my Square products and payment channels can apply a credit card surcharge today — specifically my online store, Virtual Terminal, and Appointments if I use them — and while the feature is in beta, what would change for me when it reaches general availability?"
