Your customer may haul their screenings home for their own use, or you have two options
if you buy and sell screenings. You can buy their screenings outright and pay them out as
a credit on the grain cleaning invoice, or you may simply hold and accumulate them for
later resale to a third party.
If you hold the screenings for resale in the future, SCPM will track whose screenings
you are holding and the quantities involved. After shipping you can then portion out
part of the proceeds of the screenings sale to your customers depending on the quantity
of screenings sold and the percentage of screenings that belonged to your customers.
