Check

Check is a payroll infrastructure platform that allows other software companies to embed payroll features directly into their own products. Think of it like Stripe, but for payroll instead of payments. Traditionally, building a payroll system from scratch takes years of work due to complex tax laws and regulations. Check solves this by providing a powerful API and pre-built components that handle all the heavy lifting—like tax calculations, filings, and money movement. This enables platforms like Homebase, ServiceTitan, and others to offer their own branded payroll service to their customers without becoming payroll experts themselves.
