Need changes in A2billing

you can already do this in A2B. Create RateCard, Create Call Plan, Assign Call Plan to the customer. Customer will be charged according to call plan/rate card...... create different call plan for different customers.... why do you need a custom page to do all this ? Feel free to write me if you have any question
