Inventory management is now as critical as Customer Acquisition Cost (CAC) for eCommerce businesses. Why? Rising warehouse costs, unpredictable supply chains, and excessive inventory holding expenses are straining profitability. Here’s what you need to know:

• Why It Matters: U.S. retailers hold $1.29 in inventory for every $1 earned, with carrying costs between 15–30%. Poor inventory practices can drain cash flow and lead to business failure.

• Key Benefits: Smarter inventory management reduces CAC by preventing stockouts, cutting discounts on excess stock, and improving customer satisfaction.

• Actionable Tips: Use data to predict demand, adopt Just-In-Time (JIT) strategies, automate restocking, and track critical metrics like inventory turnover and stockout rates.

• Tools to Use: AI-powered forecasting tools, integrated inventory systems, and software like Netstock or Blue Yonder Luminate can optimize stock levels and cut costs.

Takeaway: Managing inventory efficiently isn’t just about saving money - it’s about driving growth, improving margins, and staying competitive in today’s challenging market.

Leveraging Inventory Optimization for eCommerce Success

How Inventory and CAC Work Together

Smarter Inventory Management Lowers CAC

Managing inventory effectively has a direct impact on lowering customer acquisition costs (CAC). By keeping stock levels optimized, businesses can avoid unnecessary expenses tied to inventory challenges.

• Avoiding heavy discounts to clear excess stock

• Reducing extra ad spend caused by stock shortages

• Preventing customer churn due to unavailable products

Metrics That Matter

These inventory practices improve critical metrics, which in turn influence CAC:

"If you can't measure it, you can't manage it. The right inventory management KPIs can give you clarity about what is and isn't working in the business, so you can take action to improve your results."

Real-World Example: FMCG Success

These strategies drive real improvement. Companies like Wild Rhino and Europacific Footwear have seen great results by aligning inventory management with marketing.

Key actions they took included:

• Leveraging AI to forecast demand

• Syncing marketing campaigns with available stock

• Using data to guide inventory decisions

"When these two functions work in tandem, businesses can maintain better control over their stock and optimise their marketing efforts for increased sales and customer satisfaction." - Marketing Eye

3 Ways to Improve Inventory Management

Using Data to Predict Stock Needs

Managing inventory effectively starts with using accurate data. Did you know that 31% of online shoppers will switch to competitors after just one stockout? That number jumps to 70% after three stockouts. Clearly, predicting stock needs is critical.

Here’s how to use data to stay ahead:

• Track Lead Times
  

  Keep an eye on how long it takes for orders to arrive. This helps you reorder at the right time and maintain proper safety stock levels.

• Analyze Performance Data
  

  Dive into key metrics like:

  • Seasonal patterns

  • Sales velocity

  • Product lifecycle stages

  • Historical stockout rates

  • Market trends

  • Consumer sentiment

  • Weather impacts

  • Promotional calendars

By focusing on these data points, you can avoid stockouts while reducing unnecessary inventory. This approach sets the stage for smoother just-in-time (JIT) operations.

Just-In-Time Stock Management

JIT management is all about reducing waste and improving efficiency. For example, Nike cut lead times by 40% and boosted productivity by 20%, while Harley-Davidson slashed inventory by 75%.

To make JIT work, focus on three key areas:

• Supply Chain Optimization
  

  Build strong relationships with reliable suppliers, establish clear delivery schedules, and maintain a backup vendor network.

• Process Refinement
  

  Standardize operations, streamline production, and enforce quality control systems.

• Team Alignment
  

  Train your team on JIT principles, use Kanban signals for workflow, and ensure clear communication across departments.

These steps prepare your business for advanced automation, including restocking systems.

Setting Up Automatic Restocking

Once JIT is in place, automated restocking systems can take inventory management to the next level. Combining real-time tracking with predictive analytics ensures precise control.

Here’s what you need:

• System Integration
  

  Sync your ERP, warehouse management tools, and real-time tracking systems.

• Smart Reordering
  

  Use dynamic reorder points, calculate safety stock levels, and set optimized order quantities.

Tools and Software for Better Inventory Control

Choosing Inventory Software

When selecting inventory software, focus on tools that simplify operations and offer practical features. Here are some must-haves:

• Real-time tracking across all sales channels

• Batch tracking for managing perishable goods

• Demand trend analysis to anticipate stock needs

• Platform integration for smooth workflows

• Automated reordering to prevent stockouts

For example, Vendella International in New Zealand experienced six years of consecutive 35% year-over-year growth after adopting Unleashed inventory software. Similarly, Pinjarra Bakery in Australia saved between $30,000 and $40,000 annually by integrating a B2B eCommerce store.

"Unleashed makes our lives easier because it works across every aspect of our business. It's a very efficient platform." - Ben Russell-Smith, Lazer Lamps United Kingdom

Additionally, AI tools are becoming increasingly important for improving stock management.

Using AI for Stock Predictions

AI-powered tools are transforming inventory management by improving forecasting accuracy. These tools analyze a wide range of data points, including:

• Historical sales data

• Seasonal demand changes

• Market trends

• Weather conditions

• Pricing fluctuations

• Customer buying habits

For instance, a major grocery chain used Blue Yonder Luminate to better predict seasonal demand, leading to a significant reduction in food waste.

Connecting Your Systems

Once you’ve improved forecasting with AI, it’s crucial to integrate these insights into all operational channels. Guy Courtin, VP of Industry at Tecsys, explains:

"Many retailers still sequester inventory, dividing it into separate pools for eCommerce, in-store sales, and B2B operations. This approach is maddening because, at the end of the day, you need to leverage a single inventory source to avoid added complexity and inefficiencies."

Kua Coffee in Australia saw rapid growth, expanding from 30 to over 100 customer accounts almost overnight, thanks to a unified inventory system. Key integration features include:

• Central dashboard for a complete inventory overview

• Real-time syncing to ensure updates across platforms

• Multi-channel management to streamline stock across all sales channels

Volcano Coffee Works in the UK eliminated two full days of weekly spreadsheet work by switching to an integrated system, highlighting how these solutions can dramatically boost efficiency.

Money Saved Through Better Inventory

Real Inventory Costs

Inventory costs take up a large chunk of operational expenses, often accounting for 20% to 30% of a logistics budget. For every $1 in revenue, U.S. businesses typically invest $1.32 in inventory. This ties up funds that could otherwise fuel business growth.

Here's a breakdown of holding costs:

These numbers highlight the importance of optimizing inventory. Businesses can reduce inventory levels by up to 30% with better practices. This doesn't just lower costs - it improves returns, freeing up resources for other priorities.

Inventory vs. Marketing Returns

Marketing focuses on bringing in customers, but better inventory management directly impacts profitability. Here's how:

• Working Capital: Lower inventory levels mean more cash available for other uses.

• Profit Margins: Improved inventory management boosts margins without the need to raise prices.

• Risk Reduction: Maintaining appropriate stock levels reduces both stockout risks and excess holding costs.

These improvements allow companies to reinvest in sustainable growth strategies.

"For the environment we're in, I would say companies are willing to carry more inventory and, therefore, will have more inventory cost, (even though) for some, it's still a struggle to get materials." - Tracy Smith, MBA, MAS, CPSM, President of Numerical Insights LLC

The Pareto Principle shows that 80% of a company's value is often tied to just 20% of its products. Focusing on these high-value items can maximize the impact of inventory optimization efforts.

Creating a Growth Budget

Balancing inventory and marketing investments is key. Here are some strategies to consider:

1. Calculate Economic Order Quantity (EOQ)
Figure out the ideal order size to meet demand while keeping holding costs low. This helps fine-tune both order quantities and timing.

2. Use Automated Inventory Systems
Leverage technology to reduce obsolescence, improve warehouse operations, cut labor costs, and refine demand forecasts.

3. Measure Performance
Track key metrics to ensure your inventory strategy is working:

Maintaining a strong cash flow is essential for growth. Striking the right balance between inventory and marketing investments can create a more resilient business model.
