Safety stock, also called buffer stock, is the stock you order additionally. Almost all companies will set up safety stocks to cope with emergencies. This kind of inventory helps reduce the risk of out-of-stock product sales, loss of sales, or the possibility of customer dissatisfaction.
The main purpose of safety stock is to ensure that there is enough stock for sale. Why is it necessary? Because in most industries, companies cannot determine 100% of the sales volume of a product in a given time.
Seasonal fluctuations in demand for products may require companies to hold safety stocks at certain times throughout the business cycle. Enterprises need to predict the supply speed, delivery frequency, and delivery time based on the supplier’s distance.
Intensified competition in online stores has caused businesses to pay more attention to changes in product demand. Because of the shortage of goods, your failure to deliver the goods as promised will drive customers to turn their attention to other stores. Nowadays, customers hate waiting. When they cancel an order, you will face the weakening of customer trust and competitors’ blow.
Although a certain degree of safety is needed, it must be emphasized that safety stocks come at a price. The greater the amount of safety stock held, the higher the cost of the company. These costs include warehouse rent, warehouse staff wages, security costs, and the cost of expired or obsolete inventory.
How Does Safety Stock Affect Inventory Management?
A strategic supply chain management system is vital to the success of product marketing and operations. This is related to product inventory management. Correct management measures are conducive to improving customer satisfaction, reducing operating costs, and bringing a stable cash flow to your business.
Inventory management is a reliable long-term investment. Effective safety inventory management can ensure your supply chain’s normal operation and maintain your company’s reputation without disappointing your customers.
With the rapid development of third-party logistics, 3PL‘s advanced inventory management system can save you time and money.
However, for companies with relatively small business volume, in-house management is still required. Choosing the right inventory tracking method can help improve inventory accuracy.
What Are the Types of Inventory？
Before you can improve warehouse management, you need to understand the inventory types accurately. The following are the different types of inventory:
Raw Materials, materials used to manufacture products
Work-in-Progress, unfinished product being produced
Finished Goods, finished goods stored in the warehouse, waiting to be sold or shipped
Overhaul/MRO, maintenance, repair, and operation supplies, items used to support and maintain the production process and its infrastructure. These items are usually consumed due to the production process’s needs but are not directly part of the finished product. MRO inventory includes lubricants, cleaning supplies, gloves, packaging materials, and other supplies. It also consists of some office supplies, such as staples, pencils, copy paper, etc.
Transit Inventory, the items have been loaded and are in transit.
Anticipation Inventory, to meet the expected surge in sales inventory
Decoupling Inventory, supplies, or products reserved in anticipation of stagnation in some production links
Cycle Inventory, products shipped from a manufacturer or supplier to a company, and then sold to customers immediately
Theoretical Inventory, the inventory rate in and outreaches a balanced ideal state, and inventory products can pass through the manufacturing system’s minimum stock without waiting. But in reality, the warehouse will always have some inventory (such as MRO inventory, decoupling inventory, etc.)
What inventory tracking method is the optimal solution?
You must complete the inventory count for the outbound and inbound warehouse inventory in the manual tracking system. Besides, any updates to inventory records require manual operations. You can manually copy the item number and any other relevant details, but this inventory tracking method can be time-consuming and has a higher error rate. But one advantage is that you don’t have to pay for barcode scanners and other expensive equipment.
Barcode and QR code tracking
Bar codes or QR codes are commonly used in inventory tracking. The inventory system automatically extracts detailed information by scanning the product barcode or QR. The administrator can quickly and easily change the information in the system. This inventory tracking method can achieve efficient inventory management, so 3PL service providers usually recommend this method.
As with barcode and QR code tracking, you can use RFID tracking to scan products and automatically extract their detailed information. The main difference between RFID and other scannable codes is the technology behind them. RFID tags scan more comprehensively, so they are very useful for inventory systems that move many products. However, only a few inventory management software supports RFID tracking because it requires specialized (expensive) tags and scanning equipment.
