Nothing frustrates an ecommerce shopper more than seeing the dreaded “Out of Stock” message when they’re ready to buy.
In fact, research shows that one-third of customers will switch to a competitor if their preferred product is unavailable—leading to lost revenue, reduced customer loyalty, and damaged brand trust.
But here’s the challenge: keeping inventory too high leads to wasted storage costs, dead stock, and potential cash flow issues. Keeping it too low results in disappointed customers and missed sales.
The solution? A fulfilment strategy that balances stock availability with cost efficiency. In this guide, we’ll explore how ecommerce brands can avoid stockouts, reduce lost sales, and keep customers coming back—without overloading their warehouse with excess inventory.
Stockouts don’t just happen because a product sells out too fast. Several hidden issues contribute to poor stock management, including:
To stop stockouts without overstocking, you need a strategy that combines data-driven forecasting, efficient fulfilment, and smart inventory management.
The first step to reducing stockouts is understanding what, when, and how much to stock.
✅ Analyse Historical Sales Data – Identify seasonal trends and best-selling SKUs to anticipate demand surges.
✅ Use a Rolling Stock Model – Rather than static restocking, adjust purchases based on real-time demand.
✅ Monitor Website Behaviour – Track product page visits, add-to-cart rates, and waitlist sign-ups to gauge upcoming demand.
✅ Sync Data Across All Sales Channels – Ensure stock counts are updated across Shopify, Amazon, TikTok Shop, and other platforms.
An online pet supply store using E-PickPack’s real-time inventory tracking saw a 22% reduction in stockouts by adjusting restock cycles based on purchase trends.
Many ecommerce brands underestimate supplier lead times, leading to stockouts when demand suddenly increases. The best solution? Work with a UK-based 3PL like E-PickPack to ensure fast restocking and storage flexibility.
🚀 Multi-Warehouse Storage – Store inventory across multiple locations to reduce regional stockouts.
📦 Rolling Stock Replenishment – Send inventory in smaller, more frequent shipments instead of bulk orders.
🔄 Automated Stock Alerts – Get notified when stock reaches a low threshold, allowing time to reorder.
📊 Live Inventory Syncing – Seamlessly integrate with platforms like Shopify, WooCommerce, and Amazon.
Pro Tip: If you experience high-demand spikes, pre-position inventory in key fulfilment centres to ensure stock is always available near your customers.
When an item sells out, don’t let customers leave empty-handed. Instead, capture their intent to buy by offering pre-orders or stock alerts.
✅ Enable Pre-Orders on High-Demand Products – This allows customers to purchase in advance, securing sales before stock even arrives.
✅ Send ‘Back in Stock’ Email Alerts – Notify customers the moment an item is available again.
✅ Create a Waitlist for Popular Items – This helps forecast demand and gauge interest before restocking.
✅ Provide Estimated Restock Dates – Giving customers an expected timeline improves trust and reduces frustration.
A UK beauty brand partnered with E-PickPack to introduce pre-order fulfilment, leading to a 15% increase in conversion rates on previously out-of-stock products.
Traditional ecommerce brands order stock in bulk and store it until it sells—which can lead to either too much stock or not enough. A more flexible solution is Just-in-Time (JIT) fulfilment, which aligns stock replenishment with real-time demand.
💡 E-PickPack offers JIT fulfilment solutions, allowing ecommerce brands to store inventory only when necessary while ensuring fast order dispatch.
Relying on a single supplier is a major risk—if they experience delays, you’ll be stuck without stock. Instead, work with multiple suppliers to ensure uninterrupted fulfilment.
✅ Diversify Suppliers – Work with at least two vendors per product to prevent disruption.
✅ Use UK-Based Suppliers for Fast Restocking – Local suppliers reduce lead times compared to overseas vendors.
✅ Negotiate Stock Holding Agreements – Secure priority stock with manufacturers during peak seasons.
Example:
A UK fashion brand using E-PickPack partnered with two different clothing suppliers, reducing stockout rates by 35% during seasonal peaks.
Customers want clarity, not confusion when it comes to stock availability. Providing real-time stock updates helps manage expectations and reduce cart abandonment.
✅ Show Stock Levels on Product Pages – Display "Only 3 left!" messaging to create urgency.
✅ Enable ‘Back in Stock’ Filters – Let customers filter only available products.
✅ Offer Alternative Product Recommendations – If an item is out of stock, suggest similar alternatives to keep customers shopping.
