The ease of use to administer our employee benefits, including retirement savings plans, vacation pay, group medical insurance and more! There are many great features that make this program easy for employees to access their information online anytime from anywhere without having to visit an office or call one specific phone number - it's all right there at your fingertips with no waiting in line only to be told "No you can't do that." I wish they had better organization tools so we could add additional sections like healthcare options which would really help us manage costs and give some transparency into what each member/employee has selected.
We have been able solve most issues related to tracking health benefits through EASY401K by adding our own custom fields and reporting functions to keep track of who qualifies as being 'active' versus those not active (which allows me to monitor my budget).
