How can you use safety stock to improve inventory management for high-demand food products?

If you work in food manufacturing, you know how challenging it can be to balance inventory levels and customer demand. You want to avoid stockouts, spoilage, and waste, but you also don't want to tie up too much capital in excess inventory. That's where safety stock comes in. Safety stock is the extra inventory you keep on hand to buffer against unexpected fluctuations in demand or supply. In this article, we'll explain how you can use safety stock to improve inventory management for high-demand food products.

1 What is safety stock?

Safety stock is the amount of inventory you hold above your expected sales or usage. It acts as a cushion to protect you from running out of stock in case of unforeseen events, such as spikes in demand, delays in delivery, quality issues, or natural disasters. Safety stock can help you maintain customer satisfaction, avoid lost sales, and reduce the risk of obsolescence.

In essence, safety stock is our buffer. We calculate it using factors like average demand, lead time variability (how long it takes from ordering to receiving stock), and our desired service level (how confident we want to be in not running out of product). It's a proactive strategy to avoid disappointing customers. So, when there's a sudden surge in Just4Bars orders or a hiccup in ingredient deliveries, safety stock steps in. It ensures we can still deliver our wholesome, healthy food to communities without interruptions. For us, it's an essential ingredient in our inventory management recipe for success.

The main safety inventory objective is to reduce backorder, so it is important to establish a kpi relating the over cost that represent the additional inventory against the backorder reduction or the customer satisfaction increasing. Due to extra costs involved in a safety stock strategy, we need to performance, a punctual cost/beneffits analysis.

2 How to calculate safety stock?

There are different methods to calculate safety stock, but one of the most common ones is based on the following formula:

Safety stock = (Maximum daily demand - Average daily demand) x Maximum lead time

This formula assumes that you know the maximum and average daily demand for your product, as well as the maximum lead time from your supplier. You can use historical data, market research, or forecasting techniques to estimate these variables. The higher the variability in demand or lead time, the more safety stock you need.

3 How to optimize safety stock?

Safety stock can help you avoid stockouts, but it also comes with a cost. Holding too much safety stock can increase your inventory holding costs, such as storage, insurance, taxes, and depreciation. It can also reduce your inventory turnover ratio, which measures how efficiently you use your inventory. Therefore, you need to optimize your safety stock level to balance the trade-off between service level and cost. To do this, you should analyze your demand patterns and lead times to identify the sources and frequency of variability. Then segment your products into different categories based on their demand volatility, profitability, and shelf life. Set different service level targets for each product category depending on their importance to customers and your business. Adjust your safety stock levels accordingly using the formula or a software tool that can automate the calculation. Monitor your inventory performance and customer feedback to evaluate the effectiveness of your safety stock strategy.

4 How to reduce safety stock?

Another way to improve your inventory management is to reduce your safety stock level without compromising your service level. This can help you free up cash flow, improve your inventory efficiency, and minimize waste. To do this, you should strive to improve your demand forecasting accuracy by using more reliable data sources, methods, and tools. Additionally, you can reduce lead time variability by working with reliable suppliers, negotiating shorter delivery times, and implementing lean practices. Further, increasing your inventory visibility by using a system that can track and update your inventory levels in real time across different locations and channels can help reduce safety stock. Implementing a replenishment system that can trigger orders based on actual demand and inventory levels rather than fixed intervals or quantities is also beneficial. Lastly, collaboration with customers and suppliers to share information, align expectations, and coordinate actions is essential for reducing safety stock.

Best way to reduce safety stock would be to listen to your buyers. Countless times I've received orders that everyone knows are too high but that were "indicated" by their purchasing software. You don't have to abandon the software or overly empower someone who could very well be wrong. Just make the process of creating an exception easier. Good buyers knowingly put through ridiculous orders because of the brain damage associated with getting an exception. And why not, the fallout lands on someone else.

5 How to use safety stock for high-demand food products?

High-demand food products, such as staples, snacks, or beverages, can generate a large share of your revenue and profit. However, they can also present some inventory management challenges due to their short shelf life, seasonal demand pattern, or high competition. To ensure optimal inventory management for these products, you need to use safety stock strategically. Some tips to do this include prioritizing high-demand products over low-demand products when allocating resources and space, keeping a higher safety stock level for high-demand products but not too high that it causes spoilage or waste, reviewing the safety stock level frequently and adjusting it based on changes in demand, supply, and market conditions, using dynamic pricing or promotions to stimulate demand and clear excess inventory when needed, and diversifying your product portfolio and sources of supply.
