Check is a payroll-as-a-service API that lets you embed payroll directly in your vertical SaaS, HR, or time-tracking platform. Our API abstracts away the complexities of running payroll: tax calculation, remittance, and filing, plus the movement of money between companies and employees. This enables companies to easily build fully integrated payroll products to offer to their customers. Check believes in a future where small business owners don’t have to think about payroll — it’ll simply be embedded in the platforms they already use to run their businesses. With the strong tailwinds of (1) the rise of vertical software and (2) the growth of embedded fin-tech at our back, Check is building the infrastructure to power that future, and ultimately we believe we’ll enable thousands of new platforms, millions of businesses, and hundreds of millions of workers.
