We build waste water treatment systems. Some jobs are contract service, we retain ownership of the equipment and bill by the gallon. We need to depreciate the equipment over a number of years. It has been suggested that we create an assembly item for the different pieces of equipment, and depreciate that. Some equipment like tanks are bought specifically for the job and are not inventory items. What might be the best way to do this? Can we put non-inventory items into an assembly to avoid the problem?
Thanks,
