Welcome Rob!
First - this is not the correct heading to post this under, so the admins may move your post to the appropriate place. (@rbucek)
Second - being new, I suggest you contact your Epicor folks and make sure you have access to the education website, and potentially the consulting group that implemented Epicor for your company.
Third - to answer your questions - “Global Alerts” can monitor stock levels and “Cycle Counting” will prompt you to count items on a regular basis. I would start with both of those but they will both require some additional setup and training for you and your team.
