It ensures that even if sales are higher in a given month, no product will be out of stock.<\/p>\n\n\n\n<p>&#8220;It&#8217;s available, but it&#8217;s sold out&#8221; is a common phrase in many stores. It\u2019s also not unusual to find retailers who take pride in completely selling out their inventory within a month.<\/p>\n\n\n\n<p><strong>The issue is that a sold-out inventory doesn\u2019t generate new customers. <\/strong>And new customers become frustrated with stock shortages, to the point where they may decide never to shop at that store again.<\/p>\n\n\n\n<p>A physical store needs a safety stock. An e-commerce store does too. But when a physical store expands to e-commerce, this necessity becomes even more urgent.<\/p>\n\n\n\n<p><strong>Today, this article is for e-commerce businesses that operate solely online and for those that follow a hybrid model.

This can be achieved by analyzing sales history, seasonality, and consumption trends. This way, the company can anticipate periods of higher demand and prepare to maintain an adequate stock level.<\/p>\n\n\n\n<p>Another crucial factor is efficient communication between the teams responsible for inventory management.<\/p>\n\n\n\n<p><strong>If the physical store and the e-commerce share the same stock, it is essential to have a real-time<\/strong> updated system to ensure that sales from one channel do not cause product shortages in the other.<\/p>\n\n\n\n<p>Don\u2019t worry\u2014we\u2019ll discuss this in more detail in the next section.<\/p>\n\n\n\n<p>Additionally, maintaining a safety stock can help prevent issues with supplier delays or unexpected demand. Properly defining this reserve stock allows the company to continue operating even in unforeseen circumstances.<\/p>\n\n\n\n<p>Finally, investing in technology, such as ERPs and integrated management systems, helps automate inventory control, reducing errors and optimizing product replenishment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is It Worth Having Separate Stocks?<\/h3>\n\n\n\n<p>A common question for companies operating in a hybrid model is whether it is worth maintaining separate stocks for e-commerce and the physical store.<\/p>\n\n\n\n<p><strong>The answer depends on several factors, such as sales volume, available space, and the business\u2019s commercial strategy.<\/strong><\/p>\n\n\n\n<p>Keeping separate stocks can bring advantages, such as greater control over product availability in each channel. This prevents situations where a customer buys an item online only to discover that it has already been sold in the physical store.<\/p>\n\n\n\n<p><strong>Moreover, separate stocks allow the company to adopt different pricing strategies and promotions for each channel.<\/strong><\/p>\n\n\n\n<p>On the other hand, splitting stocks can increase operational costs. It requires stricter control to avoid excess inventory in one channel and shortages in the other. It can also make it harder to balance product replenishment, demanding more detailed logistical planning.<\/p>\n\n\n\n<p>A viable alternative is working with a unified stock but using an efficient management system that can automatically allocate products for each sales channel. This way, businesses can maintain flexibility without losing stock control.<\/p>\n\n\n\n<p>The final decision should consider the company\u2019s operational capacity and customer behavior in each channel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to Integrate Both Stocks with ERPs<\/h3>\n\n\n\n<p>Integrating physical and digital stocks with an ERP (Enterprise Resource Planning) system is essential for efficient management and preventing failures that could compromise operations.<\/p>\n\n\n\n<p><strong>An ERP allows all product movements to be recorded in real time, ensuring that information is always up to date.<\/strong><\/p>\n\n\n\n<p>To integrate stocks, the first step is choosing an ERP that meets the business\u2019s needs.<\/p>\n\n\n\n<p>The system should be able to synchronize e-commerce and physical store data, automatically updating available quantities whenever a sale is made.<\/p>\n\n\n\n<p>Another important feature is the ability to set up product reservation rules. For example, if a customer buys an item online, the system can immediately reserve that product in stock, preventing it from being sold in the physical store before the order is processed.<\/p>\n\n\n\n<p>Additionally, an ERP can help automate replenishment by alerting businesses to low-stock products and suggesting restocking orders based on demand in each channel.<\/p>\n\n\n\n<p>With a well-configured ERP, businesses can reduce errors, optimize logistics, and offer a smoother shopping experience for customers, regardless of their preferred sales channel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to Calculate Daily Average Consumption (DAC) in E-commerce and Integrate It with the Physical Store<\/h3>\n\n\n\n<p>Calculating Daily Average Consumption (DAC) is essential for determining minimum stock and reorder points for a product. In a hybrid e-commerce model, this calculation should consider both physical store and online sales.<\/p>\n\n\n\n<p>The basic formula to calculate DAC is:<\/p>\n\n\n\n<p><strong><em>DAC = Total Consumption in the Period \u00f7 Number of Days<\/em><\/strong><\/p>\n\n\n\n<p>For a hybrid business, DAC can be calculated separately for each channel or combined into a unified DAC.<\/p>\n\n\n\n<p>If the company chooses to keep separate stocks, it is recommended to calculate DAC individually for the physical store and e-commerce, ensuring that each has an adequate replenishment plan.<\/p>\n\n\n\n<p>If stock is integrated, DAC should include sales from both channels. This can be done using an ERP that consolidates outbound inventory data, enabling a more accurate total demand calculation.<\/p>\n\n\n\n<p>Additionally, it is important to monitor demand variations across different channels. E-commerce sales volumes can be more unpredictable due to promotions and seasonality, requiring frequent adjustments to the DAC calculation to prevent stockouts or excess inventory.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Don\u2019t Lose Sales Due to Stock or Customer Service Issues<\/h2>\n\n\n\n<p>Losing sales is a big problem in e-commerce. But it\u2019s even worse when sales are lost for the worst reasons.<\/p>\n\n\n\n<p>Stockouts are easy to prevent. The calculations are simple\u2014you just need to prepare in advance to avoid issues.<\/p>\n\n\n\n<p><strong>Another common reason for lost sales is poor customer service. If customers have unanswered questions, the sale is at risk.<\/strong><\/p>\n\n\n\n<p>The challenge is that providing real-time support to answer minor customer inquiries is difficult. You need both a team and tools to even capture these questions.<\/p>\n\n\n\n<p>Leadster\u2019s <strong>ShopBot<\/strong> solves both issues. It serves as a platform for capturing customer inquiries\u2014customers ask the chatbot questions\u2014and the responses are automated.<\/p>\n\n\n\n<p>Best of all, this chatbot is powered by ChatGPT, capable of responding in natural language at any time.<\/p>\n\n\n\n<p><strong>Take a guided test today by clicking the banner below\u2014I\u2019ll be waiting for you!<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/getleadster.com\/leadster-ai\/\" target=\"_blank\" rel=\" noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"980\" height=\"365\" src=\"https:\/\/getleadster.com\/blog\/wp-content\/uploads\/2024\/01\/en-dk-3.webp\" alt=\"\" class=\"wp-image-2670\" srcset=\"https:\/\/getleadster.com\/blog\/wp-content\/uploads\/2024\/01\/en-dk-3.webp 980w, https:\/\/getleadster.com\/blog\/wp-content\/uploads\/2024\/01\/en-dk-3-300x112.webp 300w, https:\/\/getleadster.com\/blog\/wp-content\/uploads\/2024\/01\/en-dk-3-768x286.webp 768w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" \/><\/a><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Safety stock is extremely important for e-commerce, but maximum and minimum stock levels, as well as the reorder point, are too.
