The company handles payroll calculation and payment for hundreds of thousands of US employers. It aggregates the payroll records that accumulate in that work into a monthly reading of how much private employment grew or shrank, and because it lands two days before the government jobs report the market treats it as the first signal of that week. Its method and coverage differ from the official statistics, so the two often disagree, and it is generally used for direction rather than for the size of the number.
