Out-of-stock item listing management on sales channels

**Purpose**

1.1. Automatically manage and synchronize out-of-stock acrylic items across multiple retail sales channels to prevent overselling, ensure accurate inventory reflection, notify relevant teams, and streamline restocking processes.
1.2. Reduce manual intervention by triggering instant updates and notifications when acrylic supplies reach zero inventory or are flagged as unavailable.
1.3. Maintain positive customer experience by promptly removing or hiding listings that are out-of-stock to avoid order cancellations.

**Trigger Conditions**

2.1. SKU quantity for an acrylic item drops below a defined threshold (e.g., 0 or restock level).
2.2. Inventory feed from ERP, POS, or warehouse system reports a negative or unavailable count for listed acrylic supplies.
2.3. Product status change (manual or automated) to ‘out-of-stock’ in back-office system.
2.4. Purchase order status updated to ‘backordered’ or ‘delayed’ from suppliers.
