What does it mean to have an established payroll system?
Payroll is the process by which employers pay employees, at the end of a regularly set period, for the work they have completed. An effective and efficient payroll process ensures that employees are paid accurately and consistently: their pay is properly calculated, tracked and doled out and the correct amounts for tax, company benefits and other deductions are withheld.
If an employer is using a manual payroll process (i.e. they are not using a licensed payroll software or a third party to manage their payroll) they will be asked to provide proof of payment sent to their intern.
