> PreProduct shows a “Product availability status” notice in areas where you can send [payment links](https://preproduct.io/docs/triggering-payment-links/), like the listing dashboard.

### Product availability status

This “product availability status” notice will either show:

- Specific issues that need fixing (e.g. zero stock without the ‘[continue selling when of stock](https://preproduct.io/docs/the-continue-selling-when-out-of-stock-box/)‘ Shopify setting enabled, or product is in draft status)
- ‘OK’ if everything is properly configured

### Fixing Issues with Payment Links

If PreProduct’s cart or payment links redirect to a broken checkout/cart page, check for these Shopify product admin issues:

**Issue:** The product has 0 stock AND the ‘continue selling when out of stock’ box isn’t checked
**Fix:** Set the product status to ‘active’ in the top right corner of the product page (ensure ‘online store’ is selected as the sales channel)

**Issue:** The product has 0 stock AND the ‘continue selling when out of stock’ box isn’t checked
**Fix:** Add stock or check the ‘continue selling when out of stock’ box in the inventory section of the Shopify product/variant page

**Issue:** The product is set to ‘draft’ instead of ‘active’
**Fix:** From the top right of the Shopify product admin, swap the status to “active”
