Slow moving and Obsolete Inventory
Slow-moving and obsolete inventory (SLOB) can quietly drain a business of its potential, tying up valuable resources and diminishing operational efficiency. Left unchecked, these items sit on the balance sheet like dead weight, taking up precious warehouse space, locking up working capital, and limiting a company’s ability to pivot or scale. Understanding and addressing slow-moving and obsolete inventory is crucial for maintaining a lean and responsive supply chain.
The Impact of SLOB on the Business
Tied-Up Capital Inventory that doesn't sell ties up capital that could otherwise be used to invest in higher-turnover products, marketing, or business expansion. SLOB essentially becomes frozen cash, which can be a considerable strain, especially in times of tight cash flow or fluctuating demand.
Wasted Space Warehousing is expensive, and slow-moving or obsolete products take up valuable space that could be used to store faster-moving items. This leads to inefficiencies in warehouse operations, with time wasted on handling, tracking, and managing unsellable goods.
Obsolescence Costs Some inventory, especially in industries such as electronics, fashion, and food, has a limited shelf life. When a product becomes obsolete or expires, it’s not just about holding onto unsellable items—it’s about dealing with the eventual disposal or markdown at a fraction of its value.
Forecasting and Planning Inaccuracies Having too much slow-moving stock on hand distorts demand forecasts and planning. SLOB creates noise in data analysis, making it more difficult to correctly align production and procurement decisions with actual customer demand. This inefficiency ripples through the entire supply chain, impacting order quantities, production schedules, and cash flow management.
How to Spot Slow-Moving and Obsolete Inventory
Identifying slow-moving or obsolete inventory isn't always as simple as looking at stock turnover. However, it can be systematically revealed through a few key approaches:
ABC Analysis Conduct an ABC inventory analysis, which categorises stock into three classes based on turnover rate or value. ‘A’ items are high-turning, profitable products, while ‘C’ items represent slow-movers. Regularly review ‘C’ items to see if they should be discontinued or reduced in volume.
Sales History Review Items that haven’t sold within a specific timeframe, such as 6 or 12 months, are often good candidates for review. Combining this with seasonal trends and promotional impacts will provide a clearer picture of truly stagnant stock.
Regular Reporting Establish a reporting mechanism that flags inventory sitting idle for a set number of days. Regular, automated reporting will allow you to quickly spot items heading towards obsolescence before they become an even bigger problem.
Actionable Steps to Address SLOB
Once SLOB has been identified, swift and decisive action must be taken to avoid further inefficiencies. Here are several strategies to tackle slow-moving and obsolete inventory:
Incentivise Sales Once identified, push slow-moving items through targeted sales campaigns or discounted pricing strategies. Create incentives for your sales team to focus on clearing these items from the inventory.
Repurpose or Reuse In some cases, you may be able to repurpose obsolete items for internal use or in alternative applications. This works well in manufacturing, where older stock might be used in prototypes, testing, or for training purposes.
Liquidate or Donate If the inventory cannot be sold through traditional means, consider liquidation or donation. While you may not recoup full costs, these methods still offer some financial recovery or corporate social responsibility benefits.
Bundle with High-Turn Products Another approach is to bundle slow-moving stock with popular products as part of a promotion. This can reduce your SLOB while offering an attractive deal to customers.
Involve in S&OP Discussions The Sales and Operations Planning (S&OP) process is a great platform to discuss slow-moving and obsolete inventory. By reviewing product performance, demand forecasts, and operational plans, S&OP provides the data and collaboration needed to make informed decisions about managing SLOB. The cross-functional dialogue in S&OP helps ensure alignment between sales, marketing, and operations, allowing businesses to take proactive measures rather than react after the fact.
Prevention is Key
The best way to deal with SLOB is to prevent it from accumulating in the first place. Here are some proactive strategies:
Optimise Forecasting Regularly reviewing demand forecasts with real-time data helps to prevent overstocking items that may not sell. This, again, can be part of the monthly S&OP review, ensuring that every department is aligned with current trends and market shifts.
Implement a Dynamic Inventory Policy Adjust reorder points and lead times based on product turnover. Products that move quickly should have more frequent reviews, while slow-moving products should be closely monitored to avoid overordering.
Lean Inventory Practices Adopting a lean approach to inventory ensures that stock levels are regularly reviewed, and purchase quantities are based on actual, not anticipated, demand. This keeps the supply chain agile and responsive.
Conclusion
Slow-moving and obsolete inventory is a reality in every business. However, by actively managing it through targeted actions and incorporating it into the broader S&OP discussions, you can limit its negative impact on the business. The key is to be proactive, regularly review inventory, and have a plan for dealing with sluggish stock before it becomes a major financial drain.
By focusing on maintaining a lean, agile inventory strategy, you’ll free up cash flow, optimise warehouse space, and ensure that your supply chain is functioning at its most efficient.
