Wow, shipping!! What a huge factor in pricing!!...Sheesh.
Jay makes a good point. When we receive chops or other materials by UPS, FedEx, motor freight, or other carriers at
our direct expense, our POS systems do not account for the transportation expenses in line item cost.
Unless we visit the line items to add-in and revise per-unit price factors representing variable transportation costs, they have to be accounted separately. Our POS system includes "set price" factors, commonly used to account for fixed labor cost, which may be a good way to add specific $ amounts per frame.
But it would be time-consuming, and how accurate could that be, anyway? If our buying habits vary, so will the shipping costs. That is, if we buy a box of moulding, the transportation cost per-foot would be different than if we buy chops or short lengths. Likewise, buying a case of ATG instead of a carton, or buying a box of matboard instead of a sheet, would carry different transportation cost factors per-unit.
Shipping
is already a big factor in pricing, and it will surely become bigger. Higher fuel prices will increasingly affect all of us, including our suppliers, and their suppliers, and their suppliers.
As increasing fuel prices work their way up the supply chain, transportation costs will be added into the item costs we pay. I would speculate that transportation cost changes might account for most of the price increases we suffer in the next few years.
In my business, transportation cost is accounted as an overhead item, not as part of COGS. That way, the variable doesn't affect material cost, it affects net profit more directly.
