Square POS is the point-of-sale product published by Block, Inc. whose /point-of-sale/ homepage positions the offering as "the all-in-one POS for sellers" with a free software tier and paid premium tiers, hardware bundles, and integrated payments processing, according to the official Square point-of-sale page and the structured product feature lists embedded in the page.
The Square POS feature set is organized around Payments, Checkout Hardware (Square Register, Square Terminal, Square Stand, Square Reader, Square Handheld), Software (Square POS, Square for Retail, Square for Restaurants, Square Appointments, Square Online, Square Invoices, Square Marketing, Square Loyalty, Square Team Management, Square Banking, Square Checking, Square Card), and Developer APIs. The published feature list highlights that Square accepts major credit cards, contactless payments, keyed-in payments, cash, and Square Gift Cards, supports offline payments with 24-hour queueing, supports instant or next-day fast transfers, custom tip amounts, automatic discounts, built-in fraud protection, dispute management, and PCI compliance, and offers a free POS for any business with a separate fee schedule for Square for Retail, Square for Restaurants, and Square Appointments.
Square publishes the /point-of-sale/ page with current free and premium tier prices, an industry-specific pricing matrix for retail, restaurant, beauty, and services, and a /square-hardware/ page for the hardware catalog. Procurement checklist for Square POS: confirm the current published price and processing rate on the official /point-of-sale/ page and the processing fees disclosure, validate the hardware tier you need (Square Register, Terminal, Stand, Reader, Handheld), check the integration coverage for your eCommerce site, accounting platform, and loyalty program, and confirm the dispute management and chargeback fee schedule. For MENA buyers, verify Square's regional availability (the product is currently available in the US, Canada, UK, Australia, Japan, and EU/EEA countries), validate the local payment methods supported, and confirm the data-residency option for your country.

Square is a payments and point-of-sale platform operated by Block, Inc. (NYSE: SQ; formerly Square, Inc.). The company was founded on 14 February 2009 by Jack Dorsey and Jim McKelvey in San Francisco, California, and was renamed Block, Inc. in December 2021 to reflect its broader portfolio of financial-technology businesses, per Block's official corporate history. The original idea for Square arose when McKelvey was unable to complete a $2,000 sale of glass faucets because he could not accept a credit card, and Dorsey and McKelvey built the first square-shaped mobile card reader, which launched publicly in 2010. According to Wikipedia and corporate filings, Block's products include Square Seller (the POS/payments product), Square Banking, Cash App, Afterpay, Bitkey, and TIDAL, and the company now processes more than $200 billion in annual gross payment volume (GPV) with Cash App serving 60M+ monthly actives. Square's payment-processing rates for in-person card-present transactions are published at 2.6% + $0.15 on its official pricing page. (Information sourced from the official Block, Inc. corporate history, Wikipedia, and the official Square pricing page, as of mid-2026.)
The Square platform is sold across multiple tiers for in-person and online sellers, per the official squareup.com pricing page. The free Square Point of Sale plan charges 2.6% + $0.15 per in-person card-present tap, dip, or swipe transaction, with no monthly software fee. Square for Restaurants adds Plus at $49 per month per location and Premium at $149 per month per location, with a Pro tier available for high-volume operators. Square also operates Square Banking (a FDIC-insured business banking account), Square Loans (working-capital advances), Square Capital, Square Payroll, Square Appointments, and Square Marketing, all managed from a single seller dashboard. Per Block's published 2024 figures, the company processes more than $200 billion in annual gross payment volume. The Square reader line includes the Square Reader for magstripe, the Square Contactless + Chip Reader, the Square Terminal, and the Square Stand.
