It appears that domain renewal reminders are sent based on the next due date. Ideally this should be done on the next invoice date. Quite often our clients ask us to renew the domain after the first reminder so we use the "Invoice selected" feature to do this. As they usually have 30 days to pay the invoice they still receive the subsequent reminders because the next due date doesn't update until the invoice is paid.
Any chance this can be tweaked, or if people disagree can we have the option in the settings?
