Automate Inventory Management with Google Sheets & Gmail

✅ What problem does this workflow solve?

Managing inventory manually requires constant monitoring, manual purchase order creation, and back-and-forth communication with suppliers.
This workflow automates the entire inventory replenishment cycle — from detecting low-stock items to generating purchase orders and emailing suppliers automatically.
It ensures accurate stock levels, reduces manual work, and prevents stockouts.

💡 Main Use Cases

🔍 Identify low-stock items automatically based on thresholds
📊 Perform scheduled daily inventory checks
🧾 Auto-generate purchase orders for items that need replenishment
✉️ Email purchase orders directly to suppliers
📄 Update Google Sheets with order and inventory tracking information

2. 📉 Get Low-Stock Items
   Reads your Google Sheets inventory file to identify items where current stock < minimum stock threshold.

3. 🧮 Process Each Low-Stock Item
   For every item below the # Header 1threshold: Calculates the required order quantity
