Do mid-market companies need a separate HRIS alongside an EOR?

It depends on the provider. Some employer of record for mid-market companies platforms, including Omni HR, bundle a full HRIS into the EOR service, covering payroll, leave, and people data in one system. Others, such as Multiplier and Papaya Global, offer more limited HRIS functionality, which may require a mid-market team to license a separate system for employees not on EOR.
