2. Product availability notifications: Setting up notifications for when products are low in stock or out of stock.

3. Backup suppliers: Identifying backup suppliers for popular products to minimize stockout risks.

4. Product substitution: Offering customers alternative products when the original product is out of stock.

5. Pre-orders: Allowing customers to pre-order products that are temporarily out of stock.

6. Regular communication: Keeping customers informed about stock status and estimated delivery times.

7. Inventory management tools: Utilizing inventory management tools to track stock levels and predict demand.

8. Dropshipping friendly policies: Negotiating policies like "ship from store" or "in-store pickup" with wholesalers.

9. Emergency stock orders: Placing emergency orders with wholesalers to restock quickly.

10. Customer service: Providing excellent customer service to manage customer expectations and resolve issues.

11. Product diversification: Diversifying product offerings to reduce dependence on a single product or supplier.
