What would be a proper way to write a return/credit for a part number made up or just "sold"
example. I sold a set of weather-techs to a customer and they don't like them so I need to issue a refund or credit but when I sold the parts I picked up from local supply house and just "sold" the part under "weather tech mat" and now it wont let me create a credit against it or a -1 to give credit. Hopefully I explained this correctly so someone understands what I am trying to do
