We were kind of forced into offering both monthly and yearly plans. Yearly plans obviously makes things easier for everyone concerned, less chance of forgetting to renew the account, less billing issues, etc. However I can understand some peoples reluctance due to bad experiences. So I guess what I would like to see anyway would be for a client to signup for a monthly plan if that's what they prefer, and if after a month or so if their happy with their host, sign up for a yearly plan. Usualyy it's cheaper too. If there're not happy with the host, then move on and try another.
