The ease of use! It's so easy to set up your account, pay bills from anywhere with an internet connection (even without wifi!). If you are looking for something that is reliable, but still keeps it simple, this could be what you need. I have seen other billers offer more features like automatic payment reminders or the ability to link multiple accounts into one interface - which would make sense if they were also offering some extra services as well, like phone/fax number setup, etc., where Herme has all these things in-house already. Easy integration between my bank account and their system via direct deposit makes everything run very smoothly. And since we're using ACH payments instead of checks, there isn't any paper clutter at our house anymore! We love not having to worry about getting paid each month. My husband no longer needs to go out every.
