Monitor WooCommerce daily revenue spikes and send Slack alerts

WooCommerce Daily Sales & Revenue Spike Monitor → Slack Alert

This workflow automatically checks your WooCommerce store’s last 24 hours of revenue, top-selling products, and cancelled orders on a daily schedule. It sends Slack notifications when sales cross a defined threshold or provides a detailed status update—including cancellation impact—if the target hasn’t been met, helping teams react quickly without manual reporting.

🚀 Quick Implementation Steps

• Set up the Schedule Trigger to run daily
• Connect WooCommerce and fetch recent orders
• Filter paid and cancelled orders separately
• Filter both datasets to the last 24 hours
• Calculate revenue, top products, and cancellation impact
• Merge and format sales and cancellation data
• Compare revenue with a configurable threshold
• Send enriched Slack alerts with sales and cancellation insights

What It Does

This workflow serves as a daily sales and revenue health monitoring assistant for your WooCommerce store.

• It runs automatically on a schedule and collects recent order data from WooCommerce via API.
• Only paid orders (Completed / Processing) are considered for revenue calculations.
• Cancelled orders are processed in a separate branch to track revenue loss.
• Orders created within the last 24 hours are filtered for both paid and cancelled orders.
• The workflow calculates total revenue, order count, average order value, and top-selling products.
• It also calculates cancelled order count and cancelled revenue to highlight potential revenue leakage.
• Sales and cancellation data are merged into a single structured object.
• An IF node checks whether revenue exceeds a predefined threshold.
• If the threshold is crossed, a Slack Sales Spike Alert is sent with cancellation context.
• If the threshold is not reached, a Slack Status / Pending Alert is sent showing progress, top products, and cancellation impact—keeping the team informed without noise.

Who’s It For

• Business owners monitoring daily sales and revenue health
• Sales and marketing teams tracking revenue spikes and losses
• E-commerce managers using WooCommerce
• Operations teams monitoring cancellations and fulfillment risks
• Non-technical users who want actionable insights without dashboards
