Keeping a short internal note on sample order workflow for each SKU pays for itself the first time a dispute arises over the Diamond Pro.

Commercial terms
Currency movement over a ninety day cycle can outweigh the difference between two competing quotations.
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
