Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Square’s rapidly growing lending platform, Square Capital, has revolutionized the way businesses and consumers obtain the funding needed to achieve their goals.

Unlike traditional business financing products, Square Capital offers are extended to pre-qualified sellers with no application process, funds are deposited as soon as the next business day, and repayment happens as a fixed percentage of daily card sales. Since the product launched in 2014, Square Capital has extended more than $9 billion to hundreds of thousands of sellers.
