What is eCommerce inventory management?
E-commerce inventory management involves planning, ordering, storing, and tracking products sold online. While it shares some aspects with the traditional inventory management process, e-commerce focuses specifically on products sold through online channels. Successful stock management ensures you meet customer demand, reduce costs, and avoid overstocking or stockouts.
Effective e-commerce inventory management allows you to:
- Track inventory levels across warehouses, third-party logistics (3PL), and dropshipping suppliers.
- Synchronize stock levels across multiple online sales channels.
- Set reorder points to maintain ideal stock levels and avoid supply chain disruptions.
Key challenges in eCommerce inventory management
Let's highlight the key challenges e-commerce owners face, identifying areas that need attention. From there, we’ll go to practical strategies to meet these challenges and optimize your inventory handling for maximum efficiency.
High demand volatility
E-commerce businesses often face unpredictable demand. Some might argue that this challenge is not unique to the e-commerce sector, which is true, but demand spikes in the online environment differ from those in physical stores in their speed and unpredictability. Online stores must account for rapid demand spikes caused by flash sales, email campaigns, social media promotions, and influencer marketing, requiring more dynamic and precise forecasting.
For most goods, especially for perishables, 100% product availability will always result in significant write-offs unless sales forecasts are accurate enough. Manual calculations are pretty time-consuming and prone to a high error rate.
Overstocking and stockouts
Overstocks can harm an e-commerce business by tying up capital, increasing carrying costs, and reducing profit margins. Unsold items may become obsolete or require heavy discounts, leading to lost revenue. Overstocking also increases the risk of dead stock, leading to higher storage costs.
On the other hand, the availability of the product the customer needs is critical. If the required item is out of stock, the online customer is more likely to switch to another online store than when visiting a brick-and-mortar store.
Big share of promotions
Intense competition and the specifics of online shopping dictate the need to provide customers with various promotions and bargains. That's why online shopping apps usually have a separate section with special offers and notify customers about current and upcoming promotions.
It can basically be said that promotional offers are a driver of online sales. Therefore, a lack of promotional items will not cause only the loss of one sale but possibly the loss of a customer as such. On the other hand, the desire to provide promotional items often leads to write-offs and the spoiling of goods.
Poor supply chain visibility
Supply chain visibility is a significant challenge for an ecommerce business due to the complexity and interconnectedness of modern supply chains. With products moving between multiple warehouses, third-party logistics providers, and distribution centers, tracking inventory in real-time becomes difficult. This lack of visibility can lead to delayed shipments and poor customer experiences.
Additionally, without clear insights into supplier performance or shipment statuses, businesses struggle to respond to disruptions, forecast demand accurately, and efficiently manage returns. Ensuring complete visibility requires seamless systems and data integration across the entire supply chain. Without accurate inventory data, over-ordering of stock outs become a major risk.
Dark store industry: features and challenges
Apart from e-commerce and brick-and-mortar stores, dark stores stand as a unique synergy of both business models. Since Tesco launched its first dark stores in the United Kingdom in 2009, this online shopping concept has rapidly expanded across Europe and around the globe. In addition to pioneers like Tesco and Sainsbury's, the market now includes major players such as Amazon, Walmart, and Ocado, as well as local chains and startups. By 2033, FMI forecasts an impressive average annual growth rate of 38% for the dark store market.
Today, the term "dark stores" can refer to several variations of this business model:
- Classic dark stores: These operations do not have physical retail locations. Customers place orders through a website or app, and products are picked and dispatched from warehouses for delivery or self-pickup. This model allows distributors to bypass intermediaries and directly enter the retail market.
- Dark stores within operating supermarkets: Here, orders are fulfilled directly from existing stores rather than dedicated warehouses. This is particularly advantageous for chains with many locations, enabling quick deliveries—an essential factor for dark store success.
While they share similar inventory management challenges with e-commerce—such as precise demand forecasting, stock visibility, and rapid fulfillment—dark stores come with their own specific complexities.
Time is a critical factor in the profitability formula for dark stores
In today's competitive landscape, where online shopping and rapid delivery services are the norm, providing the right product at the right time is key to securing customer loyalty. Two essential factors in achieving this are:
Speed of delivery
Shoppers now expect grocery shopping to be quick and convenient and often prefer ordering via smartphone with minimal wait times. Many dark stores promise delivery within 45 minutes, some even as fast as 10 minutes, like Gorillas or Flink. To meet these expectations, dark stores automate order processing, optimize warehouse layouts, develop networks of warehouse stores in residential areas, standardize delivery methods, and use data analytics for efficient route planning.
Convenient delivery slots
Offering flexible delivery times is crucial, as customers may abandon their carts if they can't find a suitable time slot. Missed sales during peak times can lead to overstock, impacting both sales and the accuracy of replenishment orders. To address this, retailers often extend their operating hours, offer promotions during "off-peak" times, and use additional resources to handle surges in demand.
However, these challenges are easily addressed by AI-based software solutions, which streamline processes, predict demand accurately, and optimize inventory and delivery logistics. With AI-driven systems, dark stores can minimize manual operations, avoid errors, and significantly reduce costs, ensuring both customer satisfaction and operational efficiency.
7 Effective eCommerce inventory management strategies
Having gone over the fundamentals, it's time to streamline your ecommerce inventory management. There are several inventory management techniques widely used by ecommerce business owners to address the above mentioned challenges.
#1 Safety stock
A safety stock buffer prepares you for unexpected demand surges or supply chain delays. Safety stock allows you to continue fulfilling orders while replenishing your inventory. Nevertheless, the appropriate amount of safety stock depends on several key factors.
Calculate safety stock using this formula:
Safety Stock = (Max daily usage x Max lead time in days) - (Average daily usage x Average lead time in days)
#2 ABC(D) inventory analytics
The ABC(D) analysis enables retailers to customize product classification based on their unique business needs. Once the criterion is chosen, products are categorized into four groups:
- Category A: These top-performing products account for about 50% of the selected criterion. They are crucial to the business, driving the most revenue, profit, or sales frequency, and thus require the strictest inventory control.
- Category B: Covering approximately 30% of the assortment, these items are essential but not as critical as Category A. While they still demand attention, the level of control needed is moderate.
- Category C: Representing 15%, Category C items have lower sales, profits, or frequency of turnover, contributing less to overall business performance. Inventory control for these products can be more relaxed.
- Category D: The remaining 5% includes the least important products, often with low sales or margins. These items typically require minimal inventory oversight.
#3 Demand planning
Analyzing historical sales data and trends allows businesses to predict future inventory needs more accurately. This minimizes the risk of overstocking or understocking while improving cash flow and customer satisfaction.
#4 Reorder point system
This inventory management technique helps ensure you never run out of stock. Use this formula to set reorder points:
Reorder Point = (Average daily usage x Lead time in days) + Safety Stock
#5 Kitting
Bundle slow-moving items and obsolete products (SLOB inventory) with bestsellers to clear old inventory and improve cash flow. This method helps free up valuable storage space and recovers the cost of unsold items.
#6 Cross-docking
Cross-docking minimizes storage time by transferring goods directly from inbound shipments to outbound orders. It’s a highly efficient system for e-commerce companies managing fast-moving goods.
#7 Automated inventory systems
Implementing inventory management software provides accurate inventory tracking across sales channels, precise demand forecasting, and reorder automation. This technology, combined with a robust warehouse management system, enhances inventory control, improves visibility, and reduces manual errors.
