Daily Inventory Monitoring & Reorder System
Daily Inventory Monitoring & Reorder System This workflow automatically monitors your WooCommerce store inventory, calculates stock health based on recent sales, classifies products, computes reorder quantities, assigns urgency levels and sends actionable alerts to Slack. This workflow runs daily to track your inventory and prevent stock issues. It fetches all active products and recent completed orders, calculates units sold in the last 30 days, evaluates stock health, and classifies products as Top Performer, Steady, At Risk, or Consider Discontinue. You receive: Daily inventory check (automated)** Database record of each product’s stock and recommended action** Slack alerts for urgent items and a daily summary** Ideal for teams wanting simple, automated visibility of inventory without manually reviewing stock levels. Quick Start – Implementation Steps Connect your WooCommerce account (products and orders). Connect Supabase to store inventory records. Connect Slack to receive alerts and daily summaries. Set the schedule time for daily checks. Review and adjust stock thresholds (lead time, safety days) if needed. Activate the workflow — daily inventory monitoring begins automatically. What It Does This workflow automates inventory monitoring: Fetches all published products from WooCommerce with current stock. Retrieves completed orders from the last 30 days to calculate sales. Calculates units sold per product and estimates average daily demand. Merges product and sales data for stock evaluation. Classifies products based on stock and demand: Top Performer Steady At Risk Consider Discontinue Calculates safety stock, reorder points, and reorder quantities. Assigns urgency levels (Normal, High, Critical) with clear action messages. Sends Slack alerts for high-priority products. Saves all inventory data into Supabase for tracking.
