Managing License and Certificate Renewal

Summary:

How do you manage renewal of certificate for your client?

Content (required):

We are managing the renewal of licenses and certificates at course assignment level as there seem to be no connection between item catalog and learning outcomes (in terms of renewal/validity dates). This is an issue for clients with different validity/renewal periods for the same certificate but different sites. Anyone with the same requirement?
