Using Drupal For Job tracking

I have been working on a project for a while with a developer. We are getting down to the wire and have only a few quirks left. This system is used for quality control for a shop. The last part of what we are trying to go is have a node that acts as a job# of sorts and be able to reference that as a number in many different content types. Is there any way to do this and have a new group of fields created on each of the content types we are using. We have looked at several modules including Corresponding Entity References and Relation and haven’t quite found the answer to what we are looking for. Any suggestions would be welcomed.
