Inventory includes raw materials, work in process, and finished goods. It is managed to meet future demand and resale goals. There are different inventory control methods like ABC analysis that categorizes items by importance. The economic order quantity model determines the optimal amount to purchase to minimize ordering and holding costs. Last in first out and first in first out are methods for issuing inventory. Periodic and perpetual systems exist for inventory counting, and ABC analysis determines the frequency of counting for each category. Efficient inventory management involves proper planning of purchasing, handling, and storage of materials.

It is also know as subcontracting.
Basically materials sold to the vendors for the purpose
of assembling.

Sub-contracting is mainly undertaken for the purpose
of avoiding wastages…
14. Way of issuing or picking the
materials
To the Sub-contractors:-
Basically the purchase department (sub- assembly buys and
Electrical automation) will post the PO in the system (material
required to prepare a particular meters and other products).
In the PO the part numbers of each components will be
mentioned and accordingly materials are picked and the person
who prepares GRN will prepare the NBX (Non Billable X note)
and finally the goods are send along with NBX note to the
respective venders.
This NBX will help the Venders to audit the goods received. The
NBX will help the vendors to check the goods received against
the PO sent to them. This how the good are issue or picked.
