Startup Idea: Accounts Payable Mobile App Startup Idea

Startup idea to develop a mobile program that links to a user's accounts payable, sends automated alerts about due bills. The program aims to reduce the hassle of manually checking every account and help users avoid late fees.

I could use a program for my phone that would link to my accounts payable and tell me what bill is due, for how much, with a week notice. It would not have to be very complicated, and I'm not sure how they would be able to get the amount due without me having to actually input it. It would cut down on any late fees that people are getting stuck with. Right now I have to go into each account and find out what the outstanding bill is, then I write it down and have to hand write a budget. It is very time consuming. If there is already software out there that does this I am not aware of it.
