Founded in 2009 in San Francisco, California by tech pioneers Jack Dorsey and Jim McKelvey under parent company Block Inc. (NYSE: SQ), Square is the global benchmark in omnichannel point-of-sale (POS) software, mobile payment hardware, and commercial financial tools. Supporting more than 4 million active business owners worldwide and processing upwards of 4 billion individual card transactions representing over $200 billion annually, Square democratised credit card processing by eliminating cumbersome legacy merchant contracts, terminal rental leases, and opaque statement fees.

Whether you are outfitting a busy high-street coffee shop with dedicated kitchen display screens, accepting mobile contactless payments at weekend farmers’ markets from £19 with the compact Square Reader, or automating daily bookkeeping reconciliations, onboarding your business with a verified Square Discount Code secures up to £10 in free account processing credit. Our merchant systems audit at BudgetFitter confirmed that Square merchant accounts activate in under 3 mins, disburse standard bank settlements within 24 hours of trade at zero transfer cost, and maintain a transparent flat rate of 1.75% across all in-person domestic and international cards.
