Automate Inventory Management with Google Sheets & Gmail

Description

✅ 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

🧠 How It Works – Step-by-Step

1. ⏰ Scheduled Trigger
The workflow runs automatically every day (or any chosen interval) to begin inventory checks without manual involvement.

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
Generates purchase order details, including
SKU / Item Name
Quantity Needed
Supplier Email
Stock Levels

4. 🔀 Conditional Flow
For each low-stock item:

Purchase Order Actions
Creates a purchase order email using the generated details
Sends the PO automatically to the supplier via Gmail
Logs the PO entry in Google Sheets with:
Item Details
Order Quantity
Supplier
Timestamp
Status (“PO Sent”)

5. 📢 Notifications
Sends purchase order emails directly to suppliers.
(Optional) Internal notifications (Slack/email) can be added for procurement visibility.

📊 Logging & Reporting
All actions — PO creation, stock levels, supplier emails — are written back to Google Sheets for complete auditability and reporting.
