It is efficient to be able to pay all bills at once since many users in a house may just be making one check to another member in the household to actually pay the individual companies. Similarly, the interface groups bills according to date, so the user is not bombarded with information that they do not want to see, and they can choose how much information should be displayed. In addition, experienced users will benefit from the constant header, which has all of the user preferences and login/logout features.
Error Prevention
There doesn't appear to be an undo feature, and if one user accidentally clicks pay all, the entire billing system could be then erroneous. Having to go to the individual bill view to pay a bill safeguards against one bill being paid over another accidentally that could occur if the bills were in a list. However, the delete features are harder for the user to click to, so it is less likely that the user will accidentally delete something useful from their account.
