[1] inventory that point thing you do not Nike Lunar Haze know the eight stock CategoriesEditor's note: The author LU Kai years engaged in e-commerce warehouse sale, inventory management, the company is now working in the Amazon. 'World network operators' Starting from this issue serial LU Kai 'stock that something' series of articles. E-commerce inventory management is a young science. As e-commerce purchases and delivery in time, space is asynchronous, so the traditional retail inventory management is relatively more complex and specialized. Although e-commerce is an emerging industry, but essentially also belong to the retail industry. Despite all kinds of electronics, networking factors aside, it is still a buy low, sell high basic pattern. However, due to electronic, network, remote of new features, resulting in a different e-commerce and traditional retail. Removed to Ctrip, e dragon represented the hotel, tourism service providers to handle, the US group to buy other than the representative of the service information providers, e-commerce companies are facing various needs of the physical inventory management. Wherein the rear end of the procurement and inventory control, and the corresponding inventory, logistics and after-sales service is very professional and complex, experience the traditional retail industry may not be suitable for e-commerce retail management. Inventory, literally understood, it refers to warehouse inventory. For production-oriented enterprises, inventories of raw materials and production can be divided into two major categories of results. For a retail business is concerned, there is no production process, all the goods are from the upper reaches of the procurement, storage in the warehouse, to give sales to the downstream. Stock, which is the sum of goods in the warehouse. But the warehouse stock, but it can not be generalized. Even a SKU, also belong to different states. To take a simple example, in the transfer process of the kind, will inevitably bump occurs, damage, these products will not damage occurs normally sold at system administration, it must Air Jordan 5 Retro also be distinguished. E-commerce operation, since the purchase and delivery on time and space are asynchronously, customer order to delivery process, there are intervals, and therefore must be distinguished from the stock structure. To accommodate this asynchronous sales process, e-commerce business inventory in the system configuration, usually divided into the following parts:. A salable stock (S) may sell stock (sellable inventory) is the site that is displayed in the foreground stock It is the largest component inventories. Most e-commerce companies, reception sites will maintain data synchronization, and make a judgment and background WMS (Warehouse Management System). When the \u0026 ldquo; salable inventory \u0026 gt; 0 \u0026 rdquo; when the goods are available for purchase, reception site will display products can be sold; and once \u0026 ldquo; salable inventory \u0026 lt; 0 \u0026 rdquo; when the reception site appears out of stock items. Generally called out does not mean there is no inventory of the warehouse, but just not to sell stock. Most companies will show whether there is inventory in the foreground, but in fact can do more detailed. Such as the former stage in Jingdong, customers in the choice of different receiving area, the system will be made in accordance with various sub-warehouse inventory data, if there is cash to help customers buy, achieve better customer experience (Figure 1). In Amazon's system, when very few available inventory quantity, it will prompt the number of customers in the foreground little, customers step up to buy, improve the conversion rate (Figure 2). The customer buy finished goods, the confirmation order, reception sites will first issue a request to the backend systems, check the number of orders for products and sales of inventory currently available quantity. If you can sell stock quantity \u0026 gt; Quantity, then inform reception site successful, otherwise it will inform insufficient foreground stock, to remind customers. After generating a new order, the client will buy the stock was reserved for subsequent delivery, the system reduced the number of available inventory, while reducing the available stock of where to go? It becomes the next section. B. Order occupation inventory (O) When generating orders, reducing the number of available inventory, orders occupancy stock (Order Occupied Inventory) an increase in the number of change orders in the amount that is the number of products, and this is very easy to understand. The reason lies in the establishment of the order occupied inventory: generation and warehouse shipping orders on time is asynchronous. The advantage of this is that: to ensure that the stock has been generated orders, this part of the customers can smoothly receipt; and when placing orders, can ensure product delivery. After the establishment of the order if occupied stock, will produce lower customer orders, inventory found no embarrassment goods can be sent in. While processing orders, but the order has been occupied for the stock, regardless of the sales prospects of. After the order of the library system, deductions are only occupied by stock orders. C. can not sell stock (U) often speaks to the theory of realistic, these words apply to the terms of inventory management, inventory system that records need to correspond with the physical inventory. The examples in front of them, the products can not be sold due to the damage in the system Air Jordan 12 must have the appropriate status. In practice, because many can not make normal sales, such as packaging damage, failure of performance, model number wrong and so on. For realistic theory in the system will define this part of the inventory as non-sale (Unsellable Inventory). Not sales of inventory in the system there are two types of labeling method. One is to Air Jordan 7 Retro use a different SKU code to distinguish, for example, encoding a normal commodity SKU is 351038, it corresponds to the SKU coding can not sell stock is 351038U; Another way is to use the same SKU, but open up a specialized We can not sell stock area, all non-sales stock unified management. D. Lock Stock (L) in sales, a sales promotion often use the price reduction, the effect of this approach will be very good, successful price promotions in a very short period of time commodity sold out, can be sold stock orders directly into occupied stock. But there are some cases, the seller does not want to so quickly will have sold all the stock. Sometimes because of the high cost of all inventory markdowns for all, and sometimes prevent malicious purchase competitors, more cases, it is desirable to lower prices of this product as a starter, and drive traffic to the site overall sales, which requires batch-promotional. To achieve the above purpose, it will be used to lock stock (Locked Inventory) approach. After the stock has been locked for direct sales. After a period of time promotion, available stock is 0, you can not continue to sell, you must first be unlocked can be transformed into salable inventory, continue to sell. E. virtual inventory (V) mentioned above, it is means of physical inventory in the warehouse. But the total volume of the amount of the Treasury is certain, it can not be unlimited expansion. And according to the maximum advantage of the long tail theory, e-commerce is almost unlimited merchandise display and sales capacity. How will the Treasury limited processing power and unlimited sales Goods Contact came it? Methods have already been made, virtual inventory (Virtual Inventory). There are some products, although the Treasury did not, or not a lot, but the supply channel is very smooth, can be delivered in a very short period of time warehouse, inventory turns; other products, less sales, inventory management is difficult only after generating orders to suppliers before purchasing. This part is not actually in stock, but can quickly purchase the goods called virtual inventory. Virtual inventory exists, is to make the site available for sale at the front desk is greater than the number of actual sales. When there is a virtual inventory, the electricity supplier inventory equation becomes: S = IOU-L + VF allocation occupies stock (T) many B2C companies have more than one warehouse. Multiple warehouse setting, mainly because of the scale of development to a certain extent, a large amount of stock, it is difficult stored in a separate warehouse, in addition, often will set up warehouses in the vicinity of customers gathered to meet local customer needs . Among the Treasury, there must dispatch and inventory allocation. When generating allocation plan, bring stock to a certain part of the Treasury will be occupied, which occupied part of the inventory is called redeployment stock (Transport Inventory). The allocation of a similar nature occupation occupied inventory and order stock. When the presence of occupation inventory allocation, inventory equation becomes electricity providers: S = IOU-L + V-TG inventory allocation (A) stock allocation, bound for some time, neither in the allocation of inventory warehouse. It does not exist in the allocation of the storage room, this part of the inventory like floating in the air, as referred to the allocation of the stock (Air Inventory). Located on the 1st Treasury to allocate the Treasury, the 2nd to the allocation of the Treasury coffers, before the allocation of delivery, both Treasury stock structure is: I1 = S1 + O1 + U1 + L1-V1 + T1I2 = S2 + O2 + U2 + L2-V2 + T2I = S + O + U + L-V + T if the Treasury from the 1st to allocate the amount of stock A to B the Treasury, the Treasury after the 1st allocation issue, the 2nd warehouse Nike Shoes receipt before the transfer, two Treasury stock structure is: I1 = S1 + O1 + U1 + L1-V1 + T1-AI2 = S2 + O2 + U2 + L2-V2 + T2I = S + O + U + L-V + TA can see, total inventory decreased both warehouse, inventory allocation on the road, can only count in the financial inventory, but not included in the physical inventory. Only when the redeployment is completed, enter the 2nd warehouse inventory, total inventory would be restored. I1 = S1 + O1 + U1 + L1-V1 + T1-AI2 = S2 + O2 + U2 + L2-V2 + T2 + AI = S + O + U + L-V + T These are some of the common stock of structure review In each company different business models and operational processes, with their particularity, will be used to more complex stock structure way to adapt to the actual situation of the company, there will not be too deeply.
