Sorry, lorim28...there is no quick "work-around". The only option QBO provided was to manually open each items and switch it from "non-inventory" to "inventory" item. Since we had over 1,500 different parts, this was not an acceptable solution. That's when I found was SOS Inventory. This program was developed by people who had the same experience as us and found there was NO work-around, so they created their own software to work with QBO. This company is incredible. The software is very user-friendly and the support is like nothing I have ever found with any other company (no, I do not work for this company).  I highly recommend you take a look at the site. I found the staff to be very knowledgeable, honest and professional. You will not be sorry.
