Inventory Management and Cost Control for SMEs

Inventory Management and Cost Control for SMEs
September 23, 2024

In this guide, we explore how SMEs can improve their inventory management practices while controlling costs and supporting sustainable growth.

Inventory management is a cornerstone of efficient operations for small and medium-sized enterprises (SMEs). While often overlooked, inventory management for SMEs plays a critical role in controlling costs, improving cash flow, and ensuring the business runs smoothly. Done properly it prevents stockouts, stops capital sitting in overstock, and takes the guesswork out of when to order.

Why Inventory Management Matters for SMEs

For SMEs, maintaining the right level of inventory is a balancing act. Too much stock ties up capital and increases storage costs, while too little can result in lost sales and dissatisfied customers. Proper inventory management ensures you have the right products in the right quantities at the right time.

The key reasons why inventory management is crucial for SMEs are:

  • Improved cash flow: Every unit you are not holding is cash available for something else.
  • Reduced costs: With fewer excess goods in stock, you can lower storage and holding costs.
  • Better customer satisfaction: Ensuring products are available when customers need them boosts satisfaction and repeat business.

Inventory Management Guide

Here’s a detailed guide of the main action points you should implement to manage your SME’s  inventory properly.

1. Establish Reorder Points

Reorder points are critical for preventing stockouts and overstocking. A reorder point is the minimum inventory level at which you need to reorder stock to ensure continuity in your supply chain. When setting reorder points, take into account the lead time for deliveries and average daily usage of the product.

Setting accurate reorder points helps SMEs avoid costly rush orders and overstock situations, which often lead to higher inventory holding costs.

To make the process easier, consider using an inventory management system that automates this process, ensuring that your reorder points are consistently updated. Learn more about how technology can support your business's efficiency by reading our article on data engineering.

The Arithmetic Behind the Reorder Point

The formula is short: reorder point = (average daily usage × lead time in days) + safety stock. Lead time is how long the supplier actually takes, measured rather than quoted. Safety stock is the buffer for the weeks when demand spikes or the delivery slips.

Sell ten units a day with a seven-day lead time and you consume 70 units while waiting. Add safety stock — say 20 units, sized from how variable your demand and your supplier both are — and you reorder at 90. Set it at 70 instead and every late delivery is a stockout.

When to place the order Stock on hand, one product, thirty days 7-day lead time Max 130 Reorder 90 Safety 20 Day 0 Day 30 Reorder point = daily usage × lead time + safety stock. Illustrative: 10 a day, 7-day lead, 20 units safety stock.
Figure 1Two measurements set the reorder point: how fast you sell, and how long the supplier takes. Order at 90 and the delivery lands exactly as you reach the safety floor. Order at 70 with the same seven-day lead time and you run out on the last day. The safety stock is what absorbs a late truck or a good week, which is why it is sized from how variable those two things are, not from a round number.

What Holding Stock Actually Costs

The purchase price is the part everyone tracks. The rest is where the money goes:

  • Carrying costs: warehouse rent, insurance, utilities, security, and the opportunity cost of cash sitting in stock instead of working elsewhere.
  • Shrinkage: theft, damage and spoilage.
  • Obsolescence: goods that stop being sellable at full price while they wait.
  • Ordering costs: the admin, shipping and receiving that every purchase order carries, which is why ordering more often is not free.

Track those together as a percentage of average inventory value. That single number tells you what holding stock costs rather than what buying it cost, and it is the figure that makes the case for carrying less.

When Just-in-Time Backfires

Just-in-time works when the supply chain is predictable. It fails when it is not, and the failure is expensive: a stockout costs the whole margin on the sale, which is usually more than the storage you saved.

The conditions that make it risky are worth naming. Long or unpredictable lead times. A single source for a critical item. Minimum order quantities that force you to buy in bulk anyway. Demand that swings. Seasonal businesses and importers are exposed on most of those at once.

The usual answer is a hybrid: run just-in-time on stable, fast-moving items where a late delivery is survivable, and hold safety stock on the critical or hard-to-source ones where it is not.

2. Implement Just-in-Time (JIT) Inventory Management

The just-in-time (JIT) inventory approach is designed to minimize excess inventory by ordering only what you need when you need it. This method reduces the costs associated with storing surplus goods and helps improve cash flow.

While JIT is effective for reducing overhead, it requires close coordination with suppliers. Ensure you have strong supplier relationships and reliable forecasting to avoid the risk of stockouts.

To understand the long-term benefits of this method, consider integrating forecasting tools or software to track trends and better predict demand. For more on predictive analytics and data-driven decision-making, check out our guide on making data-backed business recommendations.

3. Use Technology to Automate Inventory Management

Manual inventory tracking is error-prone, and the errors show up as miscounted stock, stockouts or overstocking. Consider inventory management software that can automate tasks like stock level tracking, reorder points, and purchase orders.

Benefits of using automated software include:

  • Real-time visibility: Know what inventory you have on hand at any time.
  • Reduced human error: Automation minimizes mistakes that can lead to inventory discrepancies.
  • Integration capabilities: Many connect to your point-of-sale and accounting software, so stock and books agree without re-keying.

With inventory software, SMEs can track products, sales and costs accurately day to day. For the habit that turns those numbers into decisions, read how data-driven financial decisions can transform your business.

4. Forecast Demand Accurately

Accurate demand forecasting is what keeps stock between the two failure modes, overstocking and running out. Forecasting should be based on historical sales data, seasonal trends, and market conditions.

By analyzing past performance and identifying patterns, SMEs can better predict demand and make informed decisions about when to order and how much to stock. This leads to more accurate budgeting, improved cash flow, and reduced carrying costs.

5. Build Better Supplier Relationships

A strong relationship with suppliers can significantly improve your inventory management. Reliable suppliers ensure timely deliveries, preventing stockouts and reducing the need for emergency orders, which can be costly.

Three things to work on:

  • Negotiate better terms: Longer payment terms or bulk discounts can improve cash flow.
  • Diversify suppliers: Relying on one supplier can be risky. Establish relationships with multiple vendors to reduce the risk of stockouts.
  • Implement clear communication: Make sure that suppliers understand your inventory needs and can deliver on time.

6. Monitor Inventory Levels Regularly

Regularly monitoring inventory levels helps SMEs stay informed about their stock status. This allows you to:

  • Identify slow-moving stock: Products that sit in inventory too long tie up capital and take up valuable storage space.
  • Adjust stock levels: Respond to market trends or seasonal fluctuations by adjusting your order quantities.
  • Detect discrepancies: Regular audits help ensure that stock levels in your system match your physical inventory.

An effective way to track inventory is through cycle counting, where small sections of the inventory are counted on a rotating basis, rather than conducting a full inventory count all at once. This method helps maintain accuracy without disrupting daily operations.

7. Reduce Excess Inventory

Carrying too much inventory results in higher holding costs and increased risk of obsolescence, particularly for products with a limited shelf life. By reducing excess stock, SMEs can free up working capital and lower storage costs.

Strategies to reduce excess inventory include:

  • Discounting slow-moving items: Offer promotions or discounts to move stagnant inventory.
  • Bundling products: Create product bundles to encourage customers to purchase more.
  • Just-in-time ordering: Implement JIT strategies to avoid over-ordering in the future.

Reducing excess inventory also leads to improved warehouse organization and quicker order fulfillment, ultimately enhancing customer satisfaction.

8. Train Employees on Best Practices

Inventory management is a team effort, and it’s essential that employees are trained on best practices. Regular training ensures that staff understand how to:

  • Track inventory accurately: Use systems correctly to input stock data and minimize errors.
  • Follow stock handling procedures: Implement standardized processes for receiving, stocking, and picking products to prevent loss or damage.
  • Conduct inventory audits: Perform regular inventory checks to identify and resolve discrepancies.

With well-trained employees, SMEs can improve the accuracy of their inventory tracking and maintain more efficient operations.

9. Implement a Contingency Plan

Every business is vulnerable to unexpected disruptions in the supply chain, from supplier delays to market shifts. A solid contingency plan can help SMEs prepare for and manage these risks.

Your contingency plan should include:

  • Backup suppliers: Ensure you have alternative sources in case your primary supplier cannot deliver.
  • Emergency stock: Maintain a buffer of critical inventory items to avoid stockouts during disruptions.
  • Flexible order policies: Negotiate flexible terms with suppliers to accommodate sudden changes in demand.

Where to Start

Take your three fastest-moving products and work out the reorder point for each: measure the real lead time from the last few purchase orders, divide recent sales by days to get daily usage, and set the safety stock from how much both have varied. Three numbers, one afternoon. Everything else on this page is easier once reordering stops being a judgement call.

Frequently asked

Questions, answered

How do you calculate a reorder point for your inventory?

The standard formula is: (average daily usage x lead time in days) + safety stock. Lead time is how long a supplier takes to deliver; safety stock is a buffer for demand spikes or shipping delays. For example, if you sell 10 units a day and delivery takes 7 days, you reach 70, then add safety stock based on how variable your demand and lead times are.

What inventory costs should SMEs track beyond the purchase price?

Carrying costs are the hidden drain: warehouse rent, insurance, utilities, security, and the opportunity cost of cash tied up in stock. Add shrinkage from theft, damage, or spoilage, plus obsolescence on items that go stale. There are also ordering costs (admin, shipping, receiving) per purchase order. Tracking these as a percentage of average inventory value shows the true cost of holding stock, not just buying it.

When does just-in-time inventory backfire for a small business?

JIT raises risk when your supply chain is unreliable. Long or unpredictable lead times, single-source suppliers, minimum order quantities, or volatile demand can cause stockouts that cost more in lost sales than you saved on storage. Seasonal businesses and those importing goods are especially exposed. A hybrid approach often works better: run JIT on stable, fast-moving items and keep safety stock on critical or hard-to-source ones.
