Movements also have an *efficiency* property to note that a percentage of the movements quantity can be lost during the movement. For example, a movement with quantity 10 and efficiency of 95% would decrease the source's inventory by 10 and increase the inventory of the destination by 9.5. This is what we call source *inventoriated quantity* and *destination inventoriated quantity*.
XXX Difference from Amount and Movement.
## Difference from Amount and Movement
XXX Reference to movement interface.
Amount is used to represent a quantity of a given resource in a given quantity unit. Amounts are used in Movements to define a subtraction of a resource from a node and its addition to another node (mirror_node).
For more information check the [Movement interface documentation](https://lab.nexedi.com/nexedi/erp5/blob/master/product/ERP5/interfaces/movement.py).

## Available Inventory
Available inventory is the inventory that can be offered to customers without risking to go out of stock. Available inventory counts incoming movements only if they really happened and count outgoing movements even if they are only planned.
XXX relationship with budget
## Relationship with budget
Budgets are documents that implement a process of forecasting and later comparing the real values with what was planned. The budget is used to define a limit total quantity or price of a set of movements between nodes. When movements are created they can be matched to the related budgets by using predicates. This can be used to check budget consumption and use it as a constraint to prevent the execution of movements that would exceed the budget.
