Track WooCommerce inventory and send reorder alerts via Gmail and Slack

WooCommerce Inventory Reorder Automation with n8n, Gmail & Slack Alerts

Automatically track product sales and inventory levels in WooCommerce and trigger reorder notifications when stock runs low or sales spike.

This n8n workflow runs daily, analyzes all WooCommerce orders to calculate SKU-wise sales, compares them with current product stock, calculates an optimal reorder quantity and sends automated alerts via Email (Gmail) and Slack when a product meets reorder conditions.

Quick Implementation Steps (Get Started Fast)

1. Import the workflow JSON into your n8n instance. 2. Connect WooCommerce, Gmail and Slack credentials. 3. Set the Schedule Trigger to run daily. 4. Update email recipients and Slack channel. 5. Activate the workflow.

What It Does

This workflow automates inventory monitoring and reorder decision-making for WooCommerce stores. On a daily schedule, it fetches all orders from WooCommerce and calculates how many units of each SKU were sold. This gives you a clear picture of recent sales velocity without manual reporting.

The workflow then retrieves live product inventory data from WooCommerce, including current stock levels and low-stock thresholds. Sales data and product data are merged using SKU matching and evaluated using logical conditions to determine whether a product should be reordered.
