Brief Explaining about Inventory Management of the Benefits, Types of Inventory, Objectives, Techniques, Challenges and Process Involved in Inventory Management
The term inventory includes raw material,
work-in-process, finished goods and stores and spares.
MRO inventories required for maintenance, repair and operating machinery.
Objectives of Inventories:
The primary objective of inventory management is to
ensure continuous supply of raw materials and facilitate uninterrupted
production.
Obtaining a reasonable utilization of people and
equipment is one of the reasons for holding inventories.
Why Is Inventory Management Important?
Inventory management is
vital to a company’s health because it helps make sure there is rarely too much
or too little stock on hand, limiting the risk of stockouts and inaccurate
records.
Public companies must track
inventory as a requirement for compliance with Securities and Exchange
Commission (SEC) rules and the Sarbanes-Oxley (SOX) Act. Companies must
document their management processes to prove compliance.
Benefits of Inventory Management
The main benefits of inventory management are that it ensures you’re able to
full fill incoming or open orders and raises profits. Inventory management
also:
Saves Money:
Understanding stock trends means you see how much of and where you have
something in stock so you’re better able to use the stock you have. This also
allows you to keep less stock at each location (store, warehouse), as you’re
able to pull from anywhere to ful fill orders — all of this decreases costs
tied up in inventory and decreases the amount of stock that goes unsold before
it’s obsolete.
Improves Cash Flow:
With proper inventory management, you spend money on inventory that sells, so
cash is always moving through the business.
Satisfies Customers:
One
element of developing loyal customers is ensuring they receive the items they
want without waiting.

How Inventory Management Works:
The Goal of inventory management is to understand stock levels and stock’s location in warehouses. Inventory management software tracks the flow of products from supplier through the production process to the customer. In the warehouse, inventory management tracks stock receipt, picking, packing and shipping.
Inventory Management
Challenges
The
primary challenges of inventory management are having too much inventory and
not being able to sell it, not having enough inventory to fulfill orders, and
not understanding what items you have in inventory and where they’re located.
Other obstacles include:
1. Getting Accurate Stock
Details:
If you
don’t have accurate stock details, there’s no way to know when to refill stock
or which stock moves well.
2.Poor Processes:
Outdated or manual processes can make work error-prone and slow down
operations.
3.Changing Customer
Demand:
Customer tastes and needs change constantly. If your system can’t track trends,
how will you know when their preferences change and why?
4.Using Warehouse Space
Well:
Staff wastes time if like products are hard to locate. Mastering inventory
management can help eliminate this challenge.
What Are the Different Types of Inventory?
There are 13 different types of inventory:
1. Raw Materials: Raw materials
are the materials a company uses to create and finish products. When the
product is completed, the raw materials are typically unrecognizable from their
original form, such as oil used to create shampoo.
2. Components: Components are like raw materials in
that they are the materials a company uses to
create and finish products, except that they remain recognizable when the
product is completed, such as a screw.
3. Work In Progress (WIP): WIP inventory
refers to items in production and includes raw materials or components, labor,
overhead and even packing materials.
4. Finished Goods: Finished goods are items that
are ready to sell.
5. Maintenance, Repair and Operations (MRO) Goods: MRO is
inventory — often in the form of supplies — that supports making a product or
the maintenance of a business.
6. Packing and Packaging Materials: There are three
types of packing materials. Primary packing protects the product and makes it
usable. Secondary packing is the packaging of the finished good and can include
labels or SKU information. Tertiary packing is bulk packaging for transport.
7. Safety Stock and Anticipation Stock: Safety stock is
the extra inventory a company buys and stores to cover unexpected events.
Safety stock has carrying costs, but it supports customer satisfaction.
Similarly, anticipation stock comprises of raw materials or finished items that
a business purchases based on sales and production trends. If a raw material’s
price is rising or peak sales time is approaching, a business may purchase
safety stock.
8. Decoupling Inventory: Decoupling
inventory is the term used for extra items or WIP kept at each production line
station to prevent work stoppages. Whereas all companies may have safety stock,
decoupling inventory is useful if parts of the line work at different speeds
and only applies to companies that manufacture goods.
9. Cycle Inventory: Companies order cycle inventory
in lots to get the right amount of stock for the lowest storage cost. Learn
more about cycle inventory formulas in the “Essential Guide
to Inventory Planning.”
10. Service Inventory: Service inventory is a
management accounting concept that refers to how much service a business can
provide in a given period. A hotel with 10 rooms, for example, has a service
inventory of 70 one-night stays in each week.
11. Transit Inventory: Also known as pipeline
inventory, transit inventory is stock that’s moving between the manufacturer,
warehouses and distribution centers. Transit inventory may take weeks to move
between facilities.
12. Theoretical Inventory: Also called
book inventory, theoretical inventory is the least amount of stock a company
needs to complete a process without waiting. Theoretical inventory is used
mostly in production and the food industry. It’s measured using the actual versus theoretical formula.
13. Excess Inventory: Also known as obsolete
inventory, excess inventory is unsold or unused goods or raw materials that a
company doesn’t expect to use or sell but must still pay to store.

Volume of Production
Process of Inventory Management and Control:
Step 1: - Determination of optimum inventory levels and procedures of their review and adjustment.
Step 2: -Determination of the degree of control that is required for the best results.
Step 3: - Planning
and design of the inventory control system.
Step 4: - Planning of the inventory control organization.
Inventory Management Techniques:
1. Always better control
(ABC) classification.
2. High, medium and low
(HML) classification.
3. Vital, essential and
desirable (VED) classification.
4. Scarce, difficult and
easy to obtain (SDE).
5. Fast moving, slow
moving and non-moving (FSN).
6. Economic order
quantity (EOQ).
7. Max-Minimum system.
8. Two bin system.
Some inventory management techniques use formulas and
analysis to plan stock. Others rely on procedures. All methods aim to improve
accuracy. The techniques a company uses depend on its needs and stock.
ABC Analysis: This method works by identifying the most and least popular types of stock.
Batch Tracking:
This method groups similar items to track expiration dates and trace defective
items.
Bulk Shipments:
This
method considers unpacked materials that suppliers load directly into ships or
trucks. It involves buying, storing and shipping inventory in bulk.
Consignment:
When practicing consignment inventory management, your business won’t pay its
supplier until a given product is sold. That supplier also retains ownership of
the inventory until your company sells it.
Cross-Docking:
Using this method, you’ll unload items directly from a supplier truck to the
delivery truck. Warehousing is essentially eliminated.
Demand Forecasting:
This form of predictive analytics helps predict customer demand.
Drop shipping:
In the practice of drop shipping, the supplier ships items directly from
its warehouse to the customer.
Economic Order Quantity
(EOQ):
This formula shows exactly how much inventory a company should order to reduce
holding and other costs.
FIFO and LIFO:
First in, first out (FIFO) means you move the oldest stock first. Last in,
first out (LIFO) considers that prices always rise, so the most
recently-purchased inventory is the most expensive and thus sold first.
Just-In-Time Inventory
(JIT):
Companies use this method in an effort to maintain the lowest stock levels
possible before a refill.
Lean Manufacturing:
This methodology focuses on removing waste or any item that does not provide
value to the customer from the manufacturing system.
Materials Requirements
Planning (MRP):
This system handles planning, scheduling and inventory control for
manufacturing.
Minimum Order Quantity:
A company that relies on minimum order quantity will order minimum amounts of
inventory from wholesalers in each order to keep costs low.
Reorder Point Formula:
Businesses use this formula to find the minimum amount of stock they should
have before reordering, then manage their inventory accordingly.
Perpetual Inventory
Management:
This technique entails recording stock sales and usage in real-time
Safety Stock:
An inventory management ethos that prioritizes safety stock will ensure there’s
always extra stock set aside in case the company can’t replenish those items.
Six Sigma:
This is a data-based method for removing waste from businesses as it relates to
inventory.
Lean Six Sigma:
This method combines lean management and Six Sigma practices to remove waste
and raise efficiency.
Demand Planning and Inventory Management:
Inventory Management Formulas:
Understanding inventory management formulas is crucial to optimizing stock levels. Multiple inventory and accounting professionals have vetted formulas to make inventory calculations easier.
Inventory Management KPIs :
Effective inventory management plays an important role throughout the supply chain. There are many key performance indicators for measuring inventory management success throughout the different organizations in the business. Understand which calculations return the most insight into your business processes is important.
How is Inventory Management different from other Process?
Inventory management
controls all stock within a company. Supply chain management manages the
process from supplier to delivering the product to the customer. Warehouse
management is a part of inventory control and focuses on stock in a specific
location.
Inventory Management vs. Inventory Control
inventory
control is a part of the overall inventory management process. Inventory
control manages the movement of items within the warehouse.
Inventory Management vs. Inventory Optimization
Inventory
optimization is the process of using inventory in the most efficient way, and
as a result minimizing the dollars spent on stock and storing those items.
You can also think about inventory optimization as seeing inventory across all locations and selling channels, being able to use any of it to fulfill customer orders—in doing so, you can hold less stock overall.
Inventory Management vs. Order Management
Inventory
management is responsible for ordering and tracking stock as it arrives at the
warehouse. Order management is the process of receiving and tracking customer
orders. Software often combines both tasks.
Inventory Management plays an important role in order management. As orders are received,
inventory can be allocated to specific orders, and then the status can be
changed in the inventory record to essentially put it “on hold” for that order.
Furthermore, when the order management system and inventory system are
integrated, the inventory system can recommend which location should fulfill
the order, based on where all the items in the order are available—this
eliminates multiple shipments for a single order.
Inventory Management vs. Supply Chain Management
Supply
chain management is a process of managing supply relationships outside a
company and the flow of stock into and through a company. Inventory management
may focus on trends and orders for the company or a part of the company.
Inventory
management is essential for a properly running supply chain. Inventory
management follows the flow of goods to, through and out of the warehouse. The
supply chain includes demand planning, procurement, production, quality, fulfilment,
warehousing and customer service—all of which require inventory visibility.
Inventory Management vs. Warehouse Management
Warehouse
management complements inventory management. Warehouse management organizes
stock in a warehouse. Inventory management manages stock and trends for many
warehouses or an entire company.
The
key to streamlining your warehouse operations is a thoughtfully laid out and
meticulously organized facility. When each product has a specific place in the
warehouse, it prevents staff from moving about inefficiently and maximizes labour
efficiency. But these processes are only as good as the inventory records that
drive them.
Inventory Management vs Logistics
Logistics
is the practice of controlling processes in a warehouse and in the
replenishment and delivery systems. Inventory management maintains stock levels
and manages stock location.
Inventory management is a crucial part of how companies manipulate their logistics. The relationship between inventory management and logistics is interdependent. Logistics need inventory management to perform their activities. Good logistics systems improve warehouse and operational activities.
INVENTORY BEST PRACTICES
The business saying if you can’t measure it, you can’t manage it” applies to inventory management and best practices. While the first best practice is keeping track of your inventory, others include:
Carry Safety Stock:
Also known as buffer stock, these products help keep companies from running out of materials or high-demand items. Once companies deplete their calculated supply, safety stock serves as a backup should the level of demand increase unexpectedly.
Invest in a Cloud-based Inventory Management Program:
Cloud-based inventory management systems let companies know in real-time where every product and SKU are located globally. This data helps an organization be more responsive, up-to-date, and flexible.
Start a Cycle Count Program:
Cycle counting benefits extend well past the warehouse by keeping stock reconciled and customers happy while also saving businesses time and money.
Use Batch/Lot Tracking:
Record information associated with each batch or lot of a product. While some businesses log precise details, such as expiration dates that provide information about their products’ sellable dates, companies that do not have perishable goods use batch/lot tracking to understand their products’ landing costs or shelf lives.
What is Multi-location inventory management?
Multi-location inventory
management is the process of managing stock across multiple locations,
warehouses, and retail stores or across multiple selling channels. With
multi-location management, you can watch stock levels in all locations and
optimize your inventory to fulfill orders.
