The openingWhy this idea is overlooked

Everyone thinks of payments as cards at checkout and ignores that payroll is one of the most recurring, high-trust money movements in the economy: every employer must pay wages, withhold taxes, and file on time, forever. The reason it is overlooked as a startable business is that it looks like boring back office, when in fact it is sticky, recurring revenue with real switching costs. The barrier is genuine though: you are moving money and handling tax compliance, which means licensing, bonding, and zero tolerance for errors that hit someone's paycheck or a tax deadline.
