Square began with a simple idea: everyone should be able to accept credit cards. We’ve been rethinking buying and selling ever since.

For sellers, we’re creating one cohesive service to run your entire business, from a register in your pocket and analytics on your laptop, to small business financing and marketing tools that drive new sales. For buyers, we’re making it faster to order from your favorite restaurants and more fun to pay your friends back.

Buying and selling sound like simple things — and they should be. Somewhere along the way, they got complicated. We’re working hard to make commerce easy for everyone.

Square’s engineers regularly contribute to the open source community and enjoy sharing our thoughts on algorithms, security, design, and other topics that will ultimately help sellers grow their business.

We let developers build an ecosystem for businesses to seamlessly accept payments online, in store, or on the go, and we’ll also share posts about our APIs and developer platform for developers to create customizable solutions that work for any size business.
