One of the main factors that drive the growth of e-commerce companies is efficiency at all levels of operations. Supply chain management is a big part of ensuring such efficiency. By leveraging specific aspects of the supply chain management process, e-commerce giants such as Amazon are growing even larger. First, supply chain management encourages positive customer reviews. Up to 72% of customers visit websites and read their reviews, and as high as 93% of online shoppers admit that they make a decision based on reviews and make purchases because of positive reviews. E-commerce businesses are coming to terms with these statistics and are using positive reviews as a major marketing and selling point. But on the other end of the spectrum, E-commerce companies are also hugely affected by negative reviews and these can have a drastic effect on sales. This is why companies need to take great measures to manage the reviews they get. Effective supply chain management ensures that orders are received and delivered quickly and effectively to customers which keeps them happy and encourages them to give positive reviews. In addition, supply chain management confirms stock availability. One of the most useful pieces of information that customers should have access to is the availability of products. Such information can mean the difference between losing a customer and making a sale. If you have ever made a purchase online, then chances are you've based your decision on knowing that the product is available and that you can get it within a certain period. For instance, when there were only 5 items left, 85% of surveyed customers reported they would make the order immediately. E-commerce giants understand that customers don't want to be disappointed. Through effective and efficient supply chain management E-commerce businesses can ensure that stock is always available for driving sales. Therefore, a major part of every E-commerce business's marketing strategy should be to ensure that products are always available. In conclusion, if you are interested in running or joining an E-commerce business, you may want to learn how to make the supply chain more effective and efficient. Learning more about supply chain management will help you boost the profit of your business.
