# Allow bookings when service is out of stock
### 🎯 **Why Enable “Continue Selling When Out of Stock”?**
If your service product reaches 0 inventory, Shopify may mark it as **Sold** **out**. When that happens, customers might not be able to continue booking on the product page.
Enabling **Continue selling when out of stock** lets customers keep booking services even when inventory is 0, which is usually what you want for appointment-based services.
