We have probably about 40 services and products for our consulting and software company. Our clients work with us on a yearly basis, renewing licensing with us. They also sometimes purchase additional services from us. 

We are currently using Deals to track sales through the pipeline. And I wanted to use PRODUCTS to track licensing with us. But it does not look like Products is how you do this. 

How do we track what products our current clients are subscribed to? What is the best module to do this?
