A point of sale is a account center or a secondary delivery point within a location.
A single site may have multiple points of sales. These can correspond to :
Different geographical locations (e.g. Brioche Dorée - rue Sainte-Catherine / Brioche Dorée - rue Porte Dijeau)
Different zones within the same establishment (e.g. bar, restaurant).
Points of sales are set up through Organization Management.
In an organization that uses different points of sales, the main location is often referred to as the "main center".
