Efficient inventory management is the backbone of a successful e-commerce operation. In PrestaShop, robust stock tracking helps you avoid the two biggest pitfalls of online retail: “out-of-stock” errors that frustrate customers and “overstocking” that ties up your capital.

Context
PrestaShop provides a built-in inventory system that updates in real-time as orders are placed. For advanced users, it also supports multi-warehouse management, allowing you to track stock across different physical locations or separate stock for retail and wholesale channels.
1. Enabling and Managing Stock Levels
By default, PrestaShop tracks quantities for every product. You can manage these settings on a per-product basis or globally.
- Individual Products: Go to Catalog > Products, open a specific item, and navigate to the Quantities tab. Here you can set the available amount and decide if you want to allow backorders (selling when stock is zero).
- Global Settings: Under Shop Parameters > Product Settings, you can define how the store behaves when a product reaches zero-whether it should be hidden from the catalog or remain visible with a “Coming Soon” label.
2. Configuring Low Stock Alerts
Automated alerts ensure you never miss a restocking deadline.
- Set Thresholds: In Shop Parameters > Product Settings, locate the “Stock” section to set a global notification threshold (e.g., alert me when any item drops below 5 units).
- Product-Specific Alerts: Within the Quantities tab of a specific product, you can override the global setting for high-turnover items that require a larger safety buffer.
- Email Notifications: Ensure the Mail Alerts module is installed and configured. This sends an automatic email to the administrator the moment a product hits its threshold.
3. Multi-Warehouse Management
If you operate from multiple locations (e.g., a main warehouse and a physical storefront), you can track stock separately.
- Define Warehouses: Navigate to Catalog > Warehouses (or use a dedicated Advanced Stock Management module depending on your PrestaShop version).
- Assign Carriers: You can specify which shipping methods are available for each warehouse.
- Stock Allocation: When an order is placed, you can manually or automatically select which warehouse should fulfill the shipment based on proximity or stock availability.
4. Synchronization with Wholesalers and Dropshipping
For stores that rely on external suppliers, manual updates are not sustainable.
- API Integration: Connect your mybox-hosted store to your supplier’s system via the PrestaShop API for real-time updates.
- CSV/XML Imports: Use the built-in import tool or a module to pull in daily stock files provided by your wholesaler.
- Dropshipping Modules: Many suppliers offer dedicated PrestaShop modules that automate the entire flow, from inventory sync to sending the order directly to the supplier’s warehouse.
Distinction: Available vs. Reserved Stock
- Physical Stock: The total number of units currently sitting on your shelves.
- Reserved Stock: Units that have been purchased by customers but have not yet been shipped.
- Available Stock: The actual number shown to customers on the storefront (Physical – Reserved = Available). PrestaShop calculates this automatically to prevent overselling.
Practical Implications
- Handling Returns: When a product is returned, you can choose to “Re-stock” it during the credit slip process. This automatically adds the unit back to your available inventory.
- Batch Updates: If you need to update stock for hundreds of items at once, it is much faster to use the SQL Manager in your panel or a “Quick Bulk Edit” module than editing products one by one.
- Audit Logs: Regularly check your Stock Movement reports to identify discrepancies or patterns in inventory loss.
Summary
Inventory management in PrestaShop turns manual tracking into an automated asset. By setting accurate thresholds, utilizing multi-warehouse features, and syncing with your suppliers, you ensure that your mybox-hosted store remains a reliable and efficient marketplace for your customers.
