Okay so this question has been bugging for the past 12 months.. Does your Wordpress site inventory pull from your DMS? Also how does that exactly work.. Are you just sending a file to your server then it deciphers it and posts it to your wordpress site.. So many questions. Also the plug-in, is that pretty much the core of the inventory portion or do you have other coding work done to get it working correctly? (I've been wanting to learn how to make a DMS work with wordpress for a very long time now)..
I've actually know someone right now who's trying to accomplish what you have done right now.. He's using wordpress and I believe he's working with a MYSLQ? Database and tables for the inventory..
