Payrolling is like when you give your money to someone else to give to the people that work for you so that they can get paid.
Let's say you are the boss of a big company that employs a lot of people. You agree to pay your employees a certain amount of money every week or every month.
But instead of giving the money directly to each employee, you give it to someone else who is in charge of payrolling. That person then divides the money up and gives each employee the right amount of money they earned for that time period.
So payrolling is a way for companies to make sure that everyone gets paid the right amount and at the right time. It can also help a company keep track of things like taxes and benefits for their employees.
