One of the most powerful things that you can do to a Drupal site is to add Drupal Commerce. With some modules and a bit of time, you can transform any Drupal 7 site into a revenue generation engine — no matter if you are selling physical products, file downloads, or just wanting to monetize digital content or access. The ability to simply enable commerce on an existing site is very powerful and can open up opportunities that you might not have considered.

One of those possibilities is paid content. This post will walk you through adding paid content to an existing blog site using two modules from our Digital Commerce Suite: Commerce License (CL) and Commerce License Billing (CLB). At DrupalCon 2014 in Austin, in the second half of Commerce by Example, we walked through the process of setting up a blog. The instructions and the demo site archive are here (link above) so you can walk through at your own pace.
