I know for my 3 stores, and many other Pedego dealers we often take in trade in bikes when a customer is looking to upgrade into something newer/nicer. After chatting with Live Support its come to my attention there is not currently a good way to handle this. Ideally what I would like to see is being able to create a non-inventory item priced at $0 so each trade in transaction can be changed accordingly to what the trade in is valued at, then be able to do a negative amount, not being registered as a discount which is what currently happens, but just be able to take that trade in amount and apply it towards taking that amount off the final sale. If there is a better way to create a trade in bike item I trust you will be able to figure that out, however the way I have explained above is the way our old POS system worked and it worked magnificently in terms of taking off the trade in amount from the total cost and manually note bike details of what bike was being traded (color, size, model, serial number, battery size) at the same time. As of right now I am still unaware a good way to do this as I am trying to complete a trade in bike on a sale as I type this out.
