ADP makes money by charging businesses a fee to handle their employees’ paychecks and taxes. They give business owners peace of mind by making sure everyone gets paid on time and the government gets the right paperwork. They won by being the first and largest “paycheck” company that everyone trusted. Their secret is that once a company connects its bank accounts to ADP, it is incredibly difficult and scary to move to a different system. They use Labor and Code Leverage to run a Managed Service model distributed via the cloud.
