What is Inventory Management?

The inventory management system involves overseeing a company's stock, which includes the ordering, storage, and sale of products. It involves the management of raw materials, components, and finished goods throughout their lifecycle.

This ensures a business has the proper stock at the right moment, balancing cost and efficiency. Inventory management affects order fulfilment, manufacturing schedules, and customer happiness, making it vital to the supply chain. Effective inventory management may optimise costs, cash flow, and customer service.

What is an Inventory Management?

Inventory management ensures a company's stock is effectively manufactured, ordered, kept, and sold. Its main objective is to fulfill consumer demand with the appropriate items at the right time and location while minimising stock and expenses. A good inventory management system streamlines processes, boosts profits, and boosts efficiency. 

Key benefits of effective inventory management include:

1. Business savings: 

Avoiding overstocking reduces carrying costs and capital. 

2. Improving efficiency: 

Streamlining inventory procedures reduces downtime and improves efficiency.

3. Increasing financial flow: 

Optimising stock levels free cash from surplus inventory. 

4. Improved financial reporting:

 For sales trends and demand forecasts, accurate inventory data is essential. 

5. Mitigating risks: 

Proper management minimizes supply chain disruptions and stockouts.

6. Cutting waste: 

Efficient inventory control helps reduce overproduction and surplus, supporting sustainability.

7. Building good relationships: 

Meeting customer expectations by having the right stock improves relationships with both suppliers and customers.

inventory management can be performed at two levels:

8. Aggregate inventory management: 

Managing overall stock levels across the business.

9. Item-level inventory management: 

Focusing on specific products or locations for more granular control.

How does Inventory Management Work?

Tracking and managing stock ensures that the correct items are available at the right time and location to fulfill client demand. A good inventory management system streamlines processes, cuts costs, and prevents overstocking and stockouts. Several important phases support seamless commodities management from procurement to sale.

Here’s a breakdown of how inventory management works:

1. Ordering: 

The ordering process comprises calculating the necessary inventory from vendors. Businesses may buy enough products to fulfil future demands without over-ordering, which might increase carrying costs, by analysing prior sales data and projecting demand.

2. Storing: 

Proper inventory storage is crucial to avoid damage and enable simple access after ordering. Businesses must consider perishability, size, and popularity depending on the items. Proper storage keeps inventory organised, safe, and ready to distribute.

3. Monitoring: 

Once inventory is stored, organisations must check stock levels continually. Inventory consumption, sales patterns, and stock movement are tracked to influence future purchases. Monitoring which items sell rapidly and which ones stagnate helps firms prevent shortages or surplus stock.

4. Selling: 

When items are sold, inventory levels are updated appropriately. Sales must be seamlessly connected with inventory systems to automatically subtract sold products from stock. This gives real-time inventory data and prevents overselling.

5. Restocking: 

Businesses use data from monitoring and sales to decide when and how much to refill. This phase helps firms balance supply and demand and avoid overstocking (which increases expenses) and understocking (which reduces revenues). Based on previous consumption and future estimates, inventory should be ideal.

By incorporating predictive analytics, inventory intelligence helps ensure that inventory levels align with actual consumption and future forecasts.

Understanding Inventory Management with an Example

Let us take an example of an electronics store to understand inventory management. The shop offers popular smartphones, tablets, and accessories. The retailer tracks stock, sales, and demand via an inventory management system to be efficient.

Based on prior statistics, the store expects smartphone sales to rise around the holidays. Demand forecasting helps them purchase more cell phones from vendors without overstocking on lower-demand commodities like older tablet models. Once inventory comes, they store it appropriately to make high-demand commodities accessible. The technology changes stock levels and creates information on fast-selling devices as clients buy them.

The system sends a replenishment warning when smartphone supply drops below a threshold. The store promptly reorders depending on sales patterns to avoid stockouts during peak season. This cycle of monitoring, selling, and restocking ensures the shop fulfils client demand without overstocking or missing sales. Effective inventory management may simplify processes, save costs, and boost corporate performance.

Key Concepts in Inventory Management

Several essential elements enable appropriate stock levels, low costs, and customer satisfaction in inventory management. Here is a brief overview:

1. Stock Control 

Inventory control oversees stock acquisition, sales, and replenishment to ensure organisations have enough. Avoiding overstocking and understocking improves efficiency and lowers expenses. 

2. Stock Tracking 

Businesses may track inventory between sites in real time using barcode scanning and RFID, eliminating mistakes and boosting order accuracy. 

3. Storekeeping 

Warehouse management optimises inventory storage and organisation to meet orders quickly and efficiently. WMS automates warehouse processes, decreasing mistakes.

4. Inventory Quality

Maintaining inventory quality ensures products meet customer expectations. By tracking condition and expiration dates, businesses minimize the risk of sending defective or outdated products, protecting customer satisfaction.

5. Distributed Inventory Management

Managing inventory across multiple locations or channels ensures the right stock is available where needed. This reduces duplication, unnecessary costs, and stock imbalances.

6. Inventory Optimization

Using demand forecasting and safety stock calculations, businesses maintain optimal stock levels to balance supply and demand, improving efficiency and reducing carrying costs.

Methods of Inventory Management

The demands, goods, and operational objectives of any organisation determine its inventory management technique. Each strategy controls stock and optimises supply chain efficiency differently. Examples of common methods:

1. Just-in-Time (JIT)

Just-in-Time (JIT) minimises inventory expenses by keeping less stock. Companies order just what they need, avoiding overstocking and storage expenses. Businesses with consistent demand and reputable suppliers benefit most from this technique.

2. Economic Order Quantity (EOQ)

The Economic Order Quantity (EOQ) method helps organisations choose the order quantity that minimises inventory expenses, including ordering and holding. It ensures firms have adequate stock to fulfil demand without overinvesting.

3. First In, first out (FIFO)

The FIFO approach sells or uses old stock first. Perishable or expiration-dated items benefit from this, minimising spoilage or obsolescence.

4. Last In, First Out (LIFO)

LIFO sells or uses the latest inventory first, unlike FIFO. This strategy helps organisations balance current expenditures with income in price-variable sectors.

5. First Expired, First Out (FEFO) 

FEFO prioritises products with the nearest expiry date for sale or use, ensuring that expired goods are not left in stock. This method is essential in industries like food, pharmaceuticals, and cosmetics, where product freshness and safety are critical.

6. Safety Stock

Extra inventory is retained as safety stock to offset demand surges or supply chain interruptions. This prevents stockouts and maintains product availability during swings.

7. Demand Forecasting

Past sales and market studies determine future inventory requirements in demand forecasting. Businesses may optimise inventory levels and minimise overstocking and understocking by precisely estimating demand.

8. Cross-Docking

Cross-docking eliminates storage by transporting items from supplier to retailer or consumer. For fast-moving product organisations, this strategy minimises handling and storage time and costs.

Each of these methods helps businesses tailor their inventory management strategy based on their unique requirements, ensuring a more efficient and cost-effective supply chain.

Inventory Management Techniques & Tools

2. Overstocking and Understocking Issues

Supply and demand must be balanced, but it's hard. Overstocking raises capital costs, storage costs, and waste if things become outdated. Understocking may lower revenue, upset consumers, and ruin a company's image. Preventing these concerns requires demand forecasting and real-time inventory monitoring.

3. Supply Chain Disruptions

Transportation delays, supplier concerns, and natural calamities may significantly influence inventory management. Stock shortages or delayed refilling may cause lost sales and operational bottlenecks. These risks may be reduced by having a flexible supply chain, numerous suppliers, and safety stock.

4. Managing Multiple Sales Channels and Locations

Many firms currently sell via physical locations, e-commerce platforms, and third-party merchants. Maintaining supply levels across channels and locations needs real-time synchronisation, making inventory management difficult. Failure to handle this complexity may cause stockouts in one area and excess in another, affecting customer happiness and profitability.

Using the correct inventory management system and solutions reduces risks, boosts efficiency, and ensures company success.
