Ali,
Sorry for the late response, I just got back from vacation and wanted to touch base with you. You should be receiving monthly emails with your invoices, let me know if that is not happening. As for our longer term plan we are in the process of developing a billing page where you can access your invoices and we have also discussed creating online dashboards to see your usage etc.
This was one of many features we have delivered during v17 and we will continue to improve on them based on your feedback. I can't guarantee a timeline right now, but I can promise we are constantly working with customers like you to improve our online experiences. As an engineer we really appreciate feedback like this so we can push it up our priority list and we can guarantee we are working on the most important items for our customers.
I will keep you abreast of any updates I have at my end.
David
