We need to find the simplest way in OE/IC to "upsell" items to our customers. Essentially we would like to sell a regular I/C item at a reduced price, while tracking sales of those upsell items. Another company I worked for used an alternate code for those items, while the system pulled inventory stock from the original item#. I have considered making an assembly item for each, but assembling each time would be too cumbersome. I also considered setting up a new item code and enabling the original item as the alternate item number, so that stock of the upsell item would always be at 0, and pull from stock of the original. If anyone has experience with the best way to set up and manage this that would be appreciated.
