I have noticed that if a bill has not run (i.e. payment missed), the only options available once a client has availed funds for the bill to be run again by the Dropbox billing system is (1) a "Renew now" option that basically forces the client to re-enter the very same credit card details already in the system (assuming the client is not intending to use a different card) and/or (2) to wait for the system to run the billing again, whenever that will be at some later stage that day or the next morning.
This is rather inconvenient. I would strongly suggest that Dropbox keeps current with other entities of its size that simply offer the option to "re-run" payment on the existing card details on their system; thus further increasing clients user experience on the site/offering.
Lastly, remember clients are in different countries that have currencies fluctuate differently in the exchange market against the US Dollar that Dropbox bill us on. For instance, today the R5,000.00 (i.e. five thousand South African Rands) I have availed to be sufficient for the current cycle of bill(s), may no longer be sufficient at a later stage should I opt to simply wait for the billing system to run by itself at a later stage (instead of the inconvenience of re-entering the same credit card details). I believe this is one of the reasons why other companies of Dropbox's size offer the ability/convenience to "re-run payment immediately" without having to re-enter the same credit card details.; companies such as Google Drive, etc.
