Our company produces custom displays for various clients. For some of our clients we offer a number of variations that only change minor details of the end product and we have accounted for this variation in quoting. Our clients prefer to only bill on a single line item bases so we typically create a part reference. I am finding limitations to the part reference since you cannot capture multiple references for a single client part (my variations).
For Example, the client wants to by a Vacuum, but I produce Vacuum Red, Vacuum Blue, Vacuum Green. This variation does not affect what was billed to the customer, but it does affect what is produced.
How can I link the main line for sale to my parent part variations. My main goals are to relieves inventory at the time of shipping and track labor for each variation.
