Understanding Inventory Management Systems

To truly grasp their significance, it’s essential to delve into how an Inventory Management System operates and the role it plays in today’s commerce environment.

Definition and core concepts

An Inventory Management System is a software application that enables businesses to track, organise and optimise the flow of goods throughout their supply chain, ensuring the right products are available in the right quantities, at the right time and in the right place.Successful inventory management relies on inventory visibility, or stock unification, which gives businesses a complete, accurate and real-time view of their inventory and its movements across the entire network. This is based on several key concepts:

1. Stock quantities: Inventory levels are imported from all sources, including manufacturers, suppliers, dropshippers, warehouses, 3PLs, stores, wholesalers, etc.
2. Stock disposition: This status or condition of stock – for example, an item may be damaged, missing, or at a certain point in the manufacturing process – with the ability to exclude dispositions from some or all sales channels.
3. Stock segmentation: Stock can be allocated to specific markets or channels based on ownership or sales strategy.
4. Stock reservations: Once a customer order is placed, the stock required to fulfil that order is reserved and made unavailable for sale.
5. Future stock: Stock that is on order or in transit and due to be received by a stock location at a given date. Future stock can be made available to customers for purchase with accurate delivery times based on their expected receipt date and available fulfilment options.
6. Safety buffers: An additional quantity of stock set at each location and at a global level to account for shortages during preparation (due to missing or damaged items).

This information is aggregated into a unified stock, which becomes the central point of reference for enterprise-wide inventory.

Importance to modern businesses

In today’s fast-changing and highly competitive commerce environment, Inventory Management Systems play a pivotal role in the success and sustainability of a business.
By automating inventory management, businesses can minimise human error and make data-driven decisions regarding purchasing, production and distribution, ensuring the right amount of stock is available to meet demand.
This helps to prevent stockouts, where products are unavailable when customers want to purchase them, as well as overstocking, which ties up capital and leads to increased carrying costs and decreased profit margins.
Finally, it allows businesses to align their inventory management strategies with overall business objectives. For instance, companies can choose to focus on minimising costs, maximising service levels, or reducing carbon emissions.

The role in supply chain management

The Inventory Management System has three key functions to support the seamless flow of goods throughout the supply chain:

1. Demand forecasting and planning: An Inventory Management System offers forecasting capabilities to accurately plan production, procurement, replenishment and distribution, ensuring products are available when and where they’re needed.
2. Supplier relationship management: Real-time insight into inventory levels, customer demand, lead times and supplier reliability enables businesses to maintain positive, collaborative relationships with suppliers.
3. Supply chain optimisation: An Inventory Management System helps to reduce excess stock and associated carrying costs, improving cash flow and profitability. It also informs decisions regarding stock allocation, replenishment, transfers and order fulfilment, reducing transportation costs, minimising stockouts and improving the customer experience.

Why companies need Inventory Management Systems

Now that we have a comprehensive understanding of the Inventory Management System, let’s explore why it’s essential for any business dealing with inventory, regardless of size or industry.

Enhancing efficiency and accuracy

Automated tracking: Automating the tracking of inventory and orders reduces the need for manual data entry, saving time and minimising the risk of human error.

Real-time visibility: Key performance indicators are updated as soon as inventory moves and orders are processed. This is especially important in industries with rapidly changing demand patterns or precarious supply chains.

Order orchestration: Each order is allocated to the best location to fulfil it based on stock levels, turnover, staff capacity, proximity to the customer, etc. to minimise stockouts and overstock situations, improve delivery times and reduce transportation costs.

Cost reduction and profit maximisation

Lower carrying costs: By effectively managing inventory levels, businesses can avoid overstocking, which leads to increased storage and insurance costs. With capital no longer tied up in excess inventory, businesses have more cash on hand to invest in growth or weather economic downturns.

Improved sales opportunities: Effective inventory management also prevents stockouts, which can result in lost sales and dissatisfied customers. With optimal product availability at each location, businesses can service every purchase intention and improve the customer experience.Minimised obsolescence: Inventory optimisation helps businesses sell through stock faster, reducing the need for discounting. Tracking product shelf life and usage also helps minimise depreciation and the risk of obsolescence, reducing waste and losses due to expired or outdated goods.

Alignment with business strategy

Strategic flexibility: Businesses can easily adapt their inventory strategies to changing market conditions and customer expectations, whether it’s responding to sudden spikes in demand, cost-cutting measures in an economic downturn, or adapting to environmental regulations.

Service-level optimisation: Businesses can align inventory levels with their customer experience objectives. High-service industries, such as luxury fashion, often prioritise product availability in stores, while cost-driven businesses focus on lean inventory practices.

Data-driven decision-making: An Inventory Management System equipped with business intelligence can provide valuable data and actionable insights to inform strategic decisions. This approach enhances a company’s ability to respond to market dynamics quickly and effectively.

The evolution and impact of technology
