Currently in R! Admin, under Account and Billing Info > Balance and Statement, all statements are shown in Reverse order.

The oldest invoices are the first ones seen, instead of what should logically be the most recent and up to date bills. This can cause confusion for customers, and upset them if their billing statements have changed significantly since they created their account
(most accounts don't keep the same number of users from their start date)

Please reverse the date order the invoice list is sorted by in R! admin for practical use.
