With the variety of payroll providers currently on the market, you cannot assume too much when it comes to the list of payroll services they provide. It is likely safe to assume that a payroll company will pay employees and file payroll taxes. Inquire about what else is included in the cost they are quoting you, including things such as: taking deductions for healthcare, retirement and other deductions; tracking employee time off; handling deductions of bonuses and other payments; and creation of year-end documents such as W2s and 1099 forms.
