What is Safety Stock, and Why is it Important in Inventory Management?

Customers frequently leave due to stockouts, which cost the business revenue and lowered the overall efficiency of the supply chain. Although running out of inventory may seem inevitable, it doesn't have to ruin a firm.  

Understanding safety stock calculations and maintaining sufficient stock levels guarantees that the supply chain functions properly despite occasional disruptions and stocking delays. Nevertheless, to maximize safety stock and meet overarching company goals, operational decision-makers must be aware of a few fundamental principles.

What Is a Safety Stock?

Cycle stocks, the inventory anticipated to be sold within a specific time frame, and safety stock are the two main categories of stock inventories. Safety stock serves as a buffer to take into consideration unknowns like:

  • Supplier delays
  • Inaccurate projections of demand or inventory
  • Not placing reorders promptly
  • Budgetary limitations

Safety stock enables your supply chain to continue operating normally even when cycle stock runs out by reducing the risks and repercussions of stockouts.  

Importance Of Safety Stock

The inconvenience of running out of supply is lessened with safety stock. With enough safety stock, you won't have to depend on your suppliers for prompt delivery or turn away clients due to low inventory levels. You are covered by safety stock until your next batch of requested products comes. Let's examine the significance of safety stock for your company:

Defense against surges in demand

Having safety stock shields you from erroneous market projections and unexpected spikes in demand that may occur during a busy or celebratory season. It is a buffer if the ordered items arrive at your warehouse later. It helps you consistently fulfill orders and ensures your business doesn't run out of popular items.

Stock up to allow for extended lead times

Even though your supplier has consistently delivered goods on schedule and there has never been a supply delay, this may not always be true. Your products may arrive later than anticipated due to unforeseen production or transportation delays, such as a backlog at your supplier's end or a shipment delay brought on by inclement weather. In these circumstances, safety stock serves as your defense against a potential stockout scenario and enables you to fulfill orders until the stock you ordered is delivered.

Safeguarding against changes in pricing

Market movements may cause the price of your goods to rise unexpectedly. This may result from unexpected market demand spikes, new competitors, abrupt shortages of raw resources, price increases for raw materials, or changes in governmental regulations. Acquiring stock at a premium price can save you money without compromising sales, provided you have adequate safety stock for these erratic times.  

Why Is Safety Stock Required for Businesses?

Running out of stock is a costly problem for businesses worldwide. According to an IHL Group analysis, stockouts cost businesses $984 billion in lost revenue globally, with North American businesses losing $144.9 billion alone.

Businesses should keep safety stock on hand for several reasons. It can rapidly prove its worth when an unforeseen circumstance arises. Many of the main justifications for having this extra inventory are listed below.  

Offset Uncertainty in Demand

Demand fluctuations are one of the main justifications for keeping safety stock on hand. Demand spikes can be caused by various circumstances, such as seasonal effects, abrupt changes in consumer behavior, panic buying, or the exit of a competitor. Safety stock allows businesses to fulfill this increased demand while giving them adequate leeway to refill inventories.

Prevent Stockouts

Safety stock can help businesses avoid running out of a certain product entirely and keep things from stopping while they find, buy, and distribute this inventory. Safety stock is a crucial link that keeps the firm operating while resolving the stockout, which might take days or weeks to complete.

Reduce the Impact of Supply Interruptions

Unexpected supplier disruptions can significantly affect your inventory levels. Examples include production problems, raw material shortages, political or legislative actions, and operational shutdowns. These disruptions also significantly affect other parts of the supply chain, affecting retail operations, delaying the production of other product components, and disrupting customer delivery timetables. Safety stock keeps the supply chain running until the disruption ends or the business has secured a replacement source, reducing the effects of supplier disruptions and lead time uncertainty.  

Cut Down on Staff and Administrative Hours

Safety stock keeps the entire supply chain operating efficiently and reduces the time needed for documentation, communication, and warehousing tasks. With a sufficient buffer, supply chain managers won't constantly be rushing to locate and reorder extra stock, saving them from the associated calls, emails, rush requests, and invoice processing. Similarly, workers in the warehouse won't unexpectedly empty trucks and replenish shelves, which may cause disruptions to other regular tasks in the warehouse.

Make Up for Prediction Errors

Sufficient safety stock guarantees uniformity and enables planners to create more precise projections throughout the enterprise. Demand projections are often correct, but unexpected developments might make them unreliable. Stock disruptions have a compounding effect on other estimates, like staff scheduling in the supply chain. These problems become particularly concerning when stock disruptions result in declining sales and other financial projections, resulting in a loss of income or clients.

Limit Expedited Shipping Costs

Revenue loss is one consequence of low inventory, but businesses also face other expenses. Suppliers asking more for expedited delivery is also likely, as is an increase in administrative and warehouse payroll expenses. If the higher demand that caused the stockout is anticipated to persist, these expenses might not be a major issue. However, the expense might not be recovered at all, if at all, in the case of stockouts brought on by disruptions or other problems.  

Assure Client Contentment

One of the best strategies for maintaining client happiness and loyalty is to keep safety stock on hand. Customers who know they can always count on a business to carry the items they need on hand will recommend the business to others and probably give important word-of-mouth promotions. That helps your firm expand and pays off greatly in the long run.

Keep Your Market Share

Losing clients and being unable to meet demand frequently translate into losing market share. Mitigating the risk of stockouts can largely help maintain customer satisfaction and lower the danger of falling behind rivals.

Boost Productivity

Safety stock makes operating more efficiently possible, even during supply shortages. Delivery drivers arrive on time, suppliers are not hurried, warehouse employees are not overworked, and reliable inventory figures are available for reporting and forecasting.

Better Connections with Retailers and Suppliers

Urgent reorders are frequently necessary for stockouts; however, most suppliers dislike being hurried because it might interfere with their business and affect their clients. Safety stock gives providers a consistent workload and lessens the need for urgent orders. Similarly, businesses collaborating with retailers can sustain positive connections by maintaining their product inventory.

Automated Safety Stock Optimization with Artificial Intelligence

Reduce supply chain risk and overstock simultaneously

Boost your profit margins usage

Overstocks and out-of-stocks destroy your margins, and the old "min-max" rules of thumb are no longer working. You can know exactly what to order and when by combining clever automation with the most accurate demand forecast in the world.

Keep your safety stock safe from unreliable supply chains

It is now more crucial than ever to consider supply chain instability. Knowing how much stock you require is insufficient. You must know when to place your orders to avoid running out of inventory due to supply chain interruptions.  

The Digital Twin's Power

Most businesses still design and manage their supply chains using static spreadsheets or planning techniques predicated on static assumptions. Though many firms have discovered that applying static models to dynamic, constantly changing real-world supply chains typically results in unsatisfactory results, these tools have proven rather effective. Leading supply chain executives have already adopted digital twin technology.

However, businesses can perform these dynamic evaluations and redesigns with the help of a digital twin. In summary, it may have transforming effects. A digital twin is crucial to creating a supply chain that can endure failures and swiftly recover from disruptive events like blocked transportation routes because it allows firms to stress test their supply chain design.
