This is the counting of goods stored in a site (or a point of sales) and can be performed at the beginning of an inventory period (called initial inventory) or at the end of an inventory period (called final inventory).
If the inventory period immediately follows a previous period, the initial inventory of the new period is equal to the final inventory of the previous period.
If there is a break with the previous period (e.g. seasonal sites, vacation centers, or the very first period of a site on Adoria), the manager must perform an initial inventory manually.
