9 Tips to Improve eCommerce Inventory Management

Written by Jeff Zoldy | September 9, 2024

Effective inventory management is the backbone of any successful eCommerce business. Mismanaged stock can lead to costly errors, lost sales, and unhappy customers. Whether you're running a small online store or a large-scale eCommerce operation, optimizing your inventory management system can help you save time, reduce costs, and ensure a smooth supply chain.

In this guide, we’ll cover practical strategies and best practices for improving inventory management in your eCommerce business, ensuring you stay ahead of the competition.

The Importance of Efficient Inventory Management in eCommerce

Inventory management is the process of tracking and controlling your stock, from procurement to warehousing, and finally to the sale and delivery of products. For eCommerce businesses, effective inventory management is essential for maintaining operational efficiency, reducing costs, and ensuring customer satisfaction.

Here are some key reasons why inventory management is crucial:

  • Prevents Stockouts and Overselling: A well-managed inventory ensures you don't run out of stock, leading to lost sales, or worse, selling products you don’t have.
  • Improves Cash Flow: By holding the right amount of stock, businesses can reduce excess inventory costs and free up cash flow for other needs.
  • Increases Customer Satisfaction: Timely fulfillment of orders without delays enhances customer trust and loyalty.
  • Reduces Wastage: Proper management prevents overstocking of items that may become obsolete or unsellable over time.

9 Tips for Better eCommerce Inventory Management

Here are nine tips you should keep in mind for optimizing your business' inventory management processes, directly from our team of experts.

Invest in a Robust Inventory Management System (IMS)

It goes without saying that to manage inventory efficiently, you need the right tools. A dedicated inventory management system (IMS) automates many aspects of stock control, making the process more accurate and less time-consuming.

A good IMS offers the following features:

  • Real-Time Stock Tracking: Know exactly how much stock you have at any given moment across multiple sales channels.
  • Automated Reordering: Set up automatic alerts or orders when stock levels reach a certain threshold.
  • Sales Data Integration: Sync sales data to track which products are selling well and which are slow-moving.
  • Multi-Warehouse Management: For businesses with multiple storage locations, the ability to monitor stock levels at each site.
  • Inventory Forecasting: Predict future demand based on historical sales data to make informed purchasing decisions.

Some popular IMS options for eCommerce businesses include TradeGecko, Fishbowl, and Cin7. These platforms integrate seamlessly with popular eCommerce platforms like Shopify, WooCommerce, and Magento.

Implement ABC Inventory Analysis

ABC analysis is a strategy used to categorize your inventory into three groups based on importance:

  • A-Class Items: These are your top-selling, high-revenue products. They make up 20% of your stock but contribute to 80% of your revenue. These items should be monitored frequently and reordered promptly to avoid stockouts.
  • B-Class Items: These are moderately important products. They make up 30% of your stock and contribute to around 15% of your revenue.
  • C-Class Items: These are low-priority items that make up 50% of your stock but only contribute to 5% of your revenue. These products don't need frequent reordering, but they still need to be tracked.

By implementing ABC analysis, you can prioritize managing your high-value products more carefully while reducing the time spent on less important stock.

Forecast Demand Accurately Using Data

Demand forecasting is essential for maintaining optimal inventory levels. If you overestimate demand, you risk overstocking, which ties up cash and increases the risk of unsold inventory. Underestimating demand, on the other hand, can lead to stockouts, lost sales, and customer dissatisfaction.

Here’s how you can improve demand forecasting:

  • Analyze Sales Trends: Study historical sales data to identify trends, such as peak shopping seasons or recurring surges in demand.
  • Use Industry Insights: Pay attention to broader market trends and customer behaviors that might affect demand for certain products.
  • Factor in Lead Times: Consider the time it takes to restock products. If you know certain items take longer to arrive, plan your purchases accordingly.
  • Collaborate with Suppliers: Maintain open communication with your suppliers to ensure that you can adjust your orders based on fluctuating demand.

Accurate demand forecasting can significantly reduce stockouts and overstocking, ensuring you always have the right products available at the right time.

Adopt the Just-in-Time (JIT) Inventory Model

The just-in-time (JIT) inventory model is an approach where businesses only order stock as it's needed, minimizing the amount of inventory they hold at any given time. This strategy can reduce holding costs and free up capital, but it requires precise coordination with suppliers.

For eCommerce businesses, the JIT model can be beneficial if:

  • You sell high-value products that are expensive to store.
  • You have reliable suppliers who can deliver stock quickly when needed.
  • Your business has predictable sales patterns.

The downside of JIT is that it leaves little room for error. Any delays in supplier shipments or unexpected demand spikes can result in stockouts. Therefore, it’s critical to maintain strong relationships with your suppliers and ensure they can meet your needs on short notice.

Conduct Regular Stock Audits

Even with the best IMS in place, manual errors and discrepancies can still occur. That’s why regular stock audits are necessary. Stock audits help identify discrepancies between the inventory recorded in your system and the actual stock on hand.

Here are three types of stock audits you can conduct:

  • Physical Inventory Audits: Conducted at regular intervals (e.g., monthly or quarterly), physical audits involve manually counting all stock to ensure system accuracy.
  • Cycle Counting: This is a continuous auditing process where a subset of inventory is checked each day, ensuring that the entire inventory is audited over time without shutting down operations.
  • Spot Checks: These are random checks on specific items to identify discrepancies between system records and actual stock.

Regular audits help detect issues early, prevent theft, and ensure your inventory records are accurate.

Centralize Your Inventory Across Sales Channels

If you sell products on multiple platforms (e.g., your own website, Amazon, eBay), it's crucial to centralize your inventory management to avoid overselling. A centralized system syncs your inventory across all channels, ensuring real-time updates on stock levels no matter where the sale occurs.

Multi-channel inventory management software like Skubana or Linnworks can streamline this process by offering integrations with major eCommerce platforms and marketplaces.

Optimize Your Warehousing and Fulfillment Process

Efficient warehousing and fulfillment operations are critical for effective inventory management. Poor organization in the warehouse can lead to delays, misplaced items, and fulfillment errors, which can negatively affect customer satisfaction.

Here’s how to improve your warehousing process:

  • Organize Products by Popularity: Keep your best-selling items in easily accessible locations to reduce picking time and fulfill orders faster.
  • Implement Barcode Scanning: Barcode scanners can automate the picking, packing, and shipping process, reducing human errors.
  • Use a Warehouse Management System (WMS): A WMS helps optimize warehouse operations by guiding workers on where to store items, tracking stock movements, and ensuring accurate order fulfillment.

Improve Supplier Relationships

Your suppliers play a critical role in your inventory management. To avoid stock shortages or delays, build strong relationships with your suppliers. Keep them informed of your inventory needs and work with them to negotiate better terms, shorter lead times, or more flexible ordering processes.

Here are some tips to improve supplier relationships:

  • Communicate Regularly: Stay in touch with your suppliers to ensure they can meet your demand and are aware of any changes in your ordering patterns.
  • Negotiate Terms: For high-volume orders, negotiate discounts or flexible payment terms that benefit your cash flow.
  • Maintain Backup Suppliers: In case of unforeseen issues with your primary supplier, have backup options available to avoid stock shortages.

Reduce Deadstock and Excess Inventory

Deadstock refers to unsold inventory that takes up warehouse space and ties up capital. It's essential to identify slow-moving products early and take action to clear them out.

Here’s how you can manage excess inventory:

  • Offer Discounts: Run promotions or offer discounts on slow-moving items to encourage sales.
  • Bundle Products: Pair slow-moving products with best-sellers as part of a bundle to move inventory faster.
  • Donate Unsellable Stock: For products that are no longer sellable, consider donating them to reduce warehousing costs and potentially gain tax benefits.

By reducing deadstock, you free up valuable warehouse space and improve your cash flow.
