Module II- (Materials)

Materials
Material refers to things used for producing an article or providing a
services. It is classified into two direct material and indirect material.
Stores
Stores includes components, tools, patterns, maintenance materials,
consumable stores etc.
Inventory
It is the raw material used to produce goods as well as the goods that
are available for sale.
Material cost control / Inventory control
It is a systematic control over purchasing, storing and consumption
of materials. It maintain a regular and timely supply of materials and
it minimize over and under stocking.
5 R in efficient material control
1. Right quantity
2. Right quality
3. Right price
4. Right time
5. Right source

 Selecting the supplier
 Placing purchase order
 Receiving of material
 Inspection of materials
 Checking the invoice
 Making payment
Stores control
It simply means control over storage of materials. The main objective
of stores control is to reduce the material cost.
Types of stores
1. Centralized stores
2. Decentralized stores
3. Central stores with sub stores
Centralized stores
It is the store where all types of material and supplies required for all
departments are stored at one place.
Advantages of centralized stores
 Better control

 To maintain up to date records related to stores.
Perpetual inventory system
This is a system of verification of materials. It is a system of records
maintained by the controlling departments which reflects the
physical movements of stock and their current balance.
Advantages of perpetual inventory system
 Quick valuation of closing stock.
 Lesser investment in materials.
 Helpful in formulating proper purchase policies.
 Adequacy of working capital.
 Immediate detection of theft and leakages.
 Beneficial in ascertaining efficiency of stores organisation.
 Overstocking and understocking can be avoided.
 It provide a moral check on the stock keeper.
Bill of materials

manufacture a product.
Functions/ Advantages of bill of material
 It reduces clerical works.
 It reduces cost of stationery.
 It avoid problem of overstocking.
 It avoid problems of understocking.
 It ascertain material cost of job.
Material abstract
It is a document which classify the records of issue of material,
material return or transfer. It is a material issue analysis sheet.
Material requisition
It is a document authorizing the store keeper to issue material stated
therein to consuming department.
Store requisition
A store requisition is a formal request made by an individual or
department within an organization to obtain specific items or
materials from the inventory or stores.
Machine cost
Machine cost refers to the expenses incurred in acquiring, operating,
and maintaining machinery or equipment used in production
processes within a business.
Material inspection note
It is a report prepared by the inspection department after inspecting
the material received.
Periodic stock taking
It refers to physical verification of entire stock once in a specific
period preferably annually and generally on the last day of an
accounting year.
Continuous stock taking
It means stock taking is conducted on regular basis.
Advantages of continuous stock taking

materials and labour.
Bin Card (Stock card)

Techniques/ Methods of inventory control (Material/ store control)
 Classification and codification of material
 Double bin system
 Stores stock levels
 Economic order quantity
 Material turnover ratio
 Stock verification system
 Imprest system
 ABC analysis
 VED analysis
 JIT techniques
Economic order quantity (EOQ)
The quantity of material to be ordered at one time is known as
economic order quantity. It is the ideal order quantity a company
should purchase to minimize inventory costs.
ABC analysis
It is an inventory management technique that determine value of
inventory items based on their importance to business.
VED analysis

goods are scheduled to arrive exactly when needed in the
manufacturing process.
Reordering level
It is that point of level of stock of a material where the storekeeper
starts the process of initiating purchase requisition for fresh supplies
of that materials.
Safety lock level
It is also known as minimum level. It is the minimum quantity of
material which must be maintained in hand at all times.
Maximum level
It is the maximum of stock which should be held in stock at any
period of year
Danger level
It is a level of stock at which normal issue of materials are stopped
and issues are made only under specific instructions.
FIFO (Fist in First Out)
Under this method, material received first are issued first.
Applicability of FIFO
 Increased warehouse space.
 Keeps stock handling to a minimum.
 Enhanced quality control.
 Warranty control.

 This method increases the possibility of clerical errors.
 This method is unsuitable in terms of rising prices.
 Issue price does not reflect the current market conditions.
LIFO (Last in First Out)
This method is a just reverse of FIFO method. Under this method,
material received last are issued first.
