I am considering using Ubercart for billing on a new site for a service and have the following requirements:
The base monthly price per user for a specific package of the service will vary based on the user tier: say, 1-5 users@$3.00/user/month, 6-10 users@$2.75 per month, 11-15user @$2.75 per month etc. The actual billing will be based on the exact number of users within that tier - for example, if an organisation has 4 users, the monthly bill will be $12 and so on. It should also be possible for an organisation to upgrade to the next tier and have the billing application automatically calculate the invoice based on the exact number of users within that tier.
Is it possible to do this out of the box with Ubercart? Or, will it require a lot of customization?
