The calculation formula of commodity sales rate is: commodity sales rate = number of products sold ÷ total number of products operated by stores * 100%. Number of products sold: the total number of products sold in all products in the store. This ratio is an index to evaluate the sales of all kinds of goods in the store. In practice, it is necessary to know the sales situation of a single product. Generally, the following calculation formula is adopted: commodity sales rate = cumulative sales quantity of commodities ÷ ending inventory quantity. The cumulative sales here can be accumulated according to the fiscal year or the sales year of the goods. Here we can pay attention to the goods with low sales rate by analyzing and comparing the sales rate. Edit this paragraph to understand that (1) the higher the sales rate, the better. (2) It is not necessarily normal that the sales rate is equal to 100%, and it is not necessarily the fault of the delayed sales. (3) In practical work, we can't just be confused by the percentage, just look at the surface of the data and find the essence of the problem without looking through the surface. The first situation of editing this paragraph: the sales rate exceeds 100% (1); the sales rate exceeds 100%, which means that the number of varieties sold in this category at a certain moment is higher than that in the current inventory, which means that the category has lost the number of varieties. (2) Reasons: A. Shortage of books and commodities; B. Stop book sales C. Virtual inventory (3) Solution: Store A should strengthen the control of book shortage. The key point of commodity out-of-stock control must be combined with regular and irregular data analysis and on-site inspection and supervision in accordance with relevant processes, and it is absolutely impossible to control the purchase, sale and storage of commodities by experience. B Pay attention to all aspects of data analysis in normal operation and management, and never operate and manage by experience. Books, like other commodities, have a lot to do with region, season, price and display position. Books sold badly in shop A are not as good as those sold in shop B or shop C. Books sold badly in shop A do not mean that they will never be sold well. We must first find out the reasons for poor sales (there are many reasons for poor sales: poor promotion, poor display, high price, poor content and too many homogenized goods); Then the product is eliminated or returned. The second case: the sales rate is lower than 100% (1). From the data point of view, such books and commodities are unsalable, at least in a certain proportion during the accounting period of the inquiry. (2) Reasons: A. There are too many varieties, especially too many homogeneous varieties. B, there is something wrong with the purchase variety structure. C, the elimination of such books and commodities is not enough or out of proportion to the purchase. D. The display and promotion strategies of such books and commodities need to be adjusted. E, too much virtual inventory. (3) Solution: A Strengthen market research, investigate readers' consumption habits and psychology, cautiously introduce new varieties of this kind of books, fully conduct market research and analysis, and purchase new books moderately and cautiously according to readers' needs. This is to strive to achieve the appropriate number of varieties. B. Adjust the display layout of unsold books, change the display position of unsold books and increase the display volume; Increase the promotion of immovable books and commodities; Change the marketing strategy of immobile books and commodities. C combined with market research, adjust the sales price of non-circulating books and commodities, and use price leverage to promote sales. D strengthen the return of goods through comprehensive data analysis. If it is determined that the sales volume of a single product is zero within a few months, and it has not improved after taking certain promotion measures, it is necessary to consider returning the product. Adjust virtual inventory in time to increase marketable inventory.
