Block, formerly known as Square, provides payment processing hardware and software for small and medium-sized businesses, along with Cash App, a peer-to-peer payments and personal finance app used by millions of individual consumers. Its seller ecosystem includes point-of-sale hardware, payment processing and business management tools that let small merchants accept card payments and run their operations without needing separate systems from multiple vendors. Cash App has grown into a broader financial services platform beyond simple peer-to-peer payments, adding features like direct deposit, a debit card and bitcoin trading. Block's revenue comes from transaction fees on payments processed through both its seller and Cash App ecosystems, along with subscription and services revenue from additional business tools it sells to merchants.
