I like that it is easy, simple & quick! Also you can always go back if something goes wrong or changes are needed in your account info- which has happened before with other billpay services but not here thus far (I've only been using this service since last October so maybe things have changed?). Nothing really as of now from my end - seems quite user friendly however they do offer training at least once per year when i need more help/advise regarding their software etc.- great customer support too through chat / email whenever necessary during those times though nothing else yet to complain about just trying out one thing then moving forward wth them :) good tool overall very helpful especially while working remotely via mobile phone most days throughout work hours. Easy online payment solution even without internet connection makes life easier by allowing me get paid faster than waiting till next day after receiving bills physically mailed home.
