“Payrolling” is a service segment of the payrolling/compliance industry. It is defined by Staffing Industry Analysts’ online Lexicon of workforce solutions ecosystem terms as a business service that for a fee provides payroll processing, paycheck writing and payroll tax administration. It is normally provided on the basis that no co-employer or joint employer relationship exists; it is plainly an administrative function. As it relates to contingent staffing, payrolling is the provision of (usually) longer-term temporary workers to a customer where the workers have been recruited — possibly interviewed, tested and approved — by the customer.
