Many businesses can outsource an entire department and save mountains of paperwork by partnering with a company specializing in online payroll and HR administration. Such a partner facilitates employee and contractor payroll while also tracking and managing benefits and taxes.

Companies of all sizes may decide to leave these details to the experts. Nobody wants to deal with the IRS more than absolutely necessary!
