It triggers every Monday, calculates date ranges and fetches order data from WooCommerce for the current week, last month and last year. It then aggregates revenue and orders, identifies the top-selling SKU and determines trends (Increase, Decrease, Flat). The final report is sent to Slack and logged to Google Sheets for auditing.\n\n**Setup Steps**\n1. Open the **Global Configuration** node to set your `trend_threshold` (e.g., 5%), `slack_webhook_url` and `google_sheet_id`.\n2. Open each **Fetch Sales** node and select your WooCommerce credentials.\n3. Authenticate the **Log to Google Sheets** node with your Google account.\n4. Activate the workflow."
