When your customer goes to order a toner online if your related items are set up correctly they should only see toners for their model. It can be a pain to maintain the related item list for existing models and getting new models in is worse. There are also tricks like remembering that staples need to be related to the finisher and not the model.
CEO Juice is working with Manufacturers to not just maintain related items for existing models but to have the related items available before new models are released. You need to have the items in your eAuto database but we will push in the relationships.
If you create an item then we will check and see if there is anything it should be related to and update you when related.
We are starting this process with Ricoh but chase your manufacturer to get us the info. We are also working on rules for configuring equipment, see this post for more http://tinyw.in/Wld8
