One of the services that are often overlooked by companies looking at PEO is the fact that they are receiving a free HRIS (human resources information system) in a lot of instances from their provider. How can that be? Think about it. If you are a PEO and you have multiple worksite locations with multiple job codes, pay codes, pay frequency, etc…what is the most efficient way to manage all of that information? HRIS. So a PEO purchases an HRIS, then has additional modules added and layers of security so they can offer what amounts to a free web-based HRIS to their clients.
