Stückzahl

Stückzahl is a German term that denotes the quantity of items in a group, batch, order, or inventory. Derived from Stück (piece) and Zahl (number), it is used across manufacturing, procurement, logistics, and inventory management to specify how many individual units are involved.

In production planning, the Stückzahl indicates the planned output for a period or the size of a batch. In procurement and order processing, it specifies how many units a supplier must deliver or a customer has requested. The term is usually expressed as an integer followed by Stück, for example, 2.500 Stück or 10.000 Stück. It is distinct from monetary terms such as Stückpreis (price per piece) or other value-based quantities.

Related concepts include Losgröße (lot size) or Stückzahl je Los (quantity per batch), Mindeststückzahl (minimum order quantity), and Stückliste (bill of materials), though they refer to different aspects of production data.

In English, Stückzahl is typically translated as quantity, unit count, or number of units. The concept is language-specific and widely used in German-speaking businesses for planning, production control, and logistics.
