Yes - automatic recurring payments or Continuous Credit Card authority as it is sometimes known (CCC).
The web owner can offer the option of annual (or other term) subscriptions by automatic payment so no renewal notices need to be sent out.
The next step would be to offer an introductory trial rate for, say 30 days, followed by, say quarterly or six-monthly payments to spread the cost over the year. That is very helpful during a recession, when many WA website users will find revenue dropping as their members cut back. To be able to spread payments looks very attractive to new prospective members: four quarterly payments of $10 is much easier on the budget than one payment of $40.
Thanks for putting this on your 'to-do' list. Any idea when it could become operative? I am, by the way, very impressed with the professionalism of your whole operation. It has taken me around three days to get the hang of managing my site. A personal best!
