This feature request seems odd, but we want to offer the same type of thing that one competitor does with his own custom-made panel, so:
- Ability to weekly raise the customer's diskspace or bandwidth based on account age, as bonus. Figures could be in fixed amounts or %age, and could be different per plan. E.g., The guy hires a 1GB HD and 200GB bandwidth plan, and for each week he stays in, he gets bonus 150MB hd and 10GB bandwidth added to his plan (usage allowance). So it he stays fr 10 monts, at the end he got an extra 1.5GB diskspace and 100GB bandwidth added to his plan, retaining the same price.
This is a smart way to keep in the customers' fidelity (especially resellers) as well as keep up with market changes due to cheaper bandwidth and cheaper diskspace throughout the years (2-3 years ago people sold hosting accounts with 200MB space and that was "much space", nowadays 2GB accounts are considered normal).
