You have to be a really useful service to price things this way. "Per user per month" means that people that don't use your software are still paying for it, which I guess is the best kind of user -- not adding any database rows, not burning any CPU, and not opening any support tickets. Good work if you can get it! Use-based pricing is my favorite pricing method, but your product has to be useful if you want to charge based on use. Most people don't have the guts to do it, because the "per user per month" is such an easy way to get money. If you go for use-based pricing, you have to make sure people actually use your thing, which is hard work!
