We believe everyone should be able to participate and thrive in the economy. So we’re building tools that make commerce easier and more accessible to all. We started with a little white credit card reader but haven’t stopped there. Our new reader helps our sellers accept chip cards and NFC payments, and our Cash app lets people pay each other back instantly. We’re empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. Let’s shorten the distance between having an idea and making a living from it. We’re here to help sellers of all sizes start, run, and grow their business—and helping them grow their business is good business for everyone.
Square’s rapidly growing financing 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 $4.5 billion to over a hundred thousand sellers.
