[Resolved] How to Sell Multiple Memberships to Individual Customers?

I sell a software product online. When people buy the software they can then access the downloads page to grab the product and updates as they become available, and access the support forum for a period of 2 years.

I have been using…

Simple WordPress Membership
Simple Membership Addon
Simple Membership BBPress Addon
Simple Membership Custom Messages
Simple Membership MailChimp Integration

…and all of these work brilliantly.

I have run into a limitation, however, and I wonder if there is a way to keep using Simple Membership while also overcoming this issue.

I now have customers who are purchasing 2 or 3 licenses for my software product to use in different environments.

Currently, when an existing customer purchases my product again, they expect that they are going to be granted a new license. What happens instead is that more membership time is added to their existing account.

The only way I can accommodate them is to have them create a separate account for each license, and of course each account needs to be associated with a unique email address.

Obviously, this is far from ideal. My licensing scheme works on the honor system, and it feels like I am punishing them for being honest.

What I really need is a way for a customer to the able to maintain multiple licenses, er, memberships, and see their remaining time in a control panel; and purchase a new one and / or chose to extend one or more of them.

I realize that I am using Simple Membership in a way that falls outside of its intended usage. But is there anything I’ve overlooked, or any ideas that will enable me to continue to remain in the Simple Membership ecosystem that has worked so well until now?
