Editing Customer (section)

===Customer===
Clients who habitually return to a seller develop [[custom (law)|custom]]s that allow for regular, sustained commerce that allows the seller to develop statistical models to optimize [[production (economics)|production]] processes (which change the nature or form of goods or services) and [[supply chain]]s (which change the location or formalize the changes of ownership or entitlement transactions). 

An "end customer" denotes the person at the end of a supply chain who ultimately purchases or utilised the goods or services.<ref>Harrison, A. and Godsell, J.
