Core Problems Addressed
Traditional raw material inventory management relies heavily on manual data entry and approval processes, which are prone to errors, approval delays, and stockout risks. This workflow automates material receipt, usage approval, and inventory updates, eliminating manual bottlenecks, reducing error rates, and improving inventory accuracy and responsiveness.
Application Scenarios
- Raw material procurement and usage management in manufacturing enterprises
- Dynamic warehouse inventory monitoring and alerting
- Multi-level approval workflows for material issuance
- Enterprises managing inventory using Google Forms, Supabase database, and email systems
Main Process Steps
-
Raw Material Receipt
- Receive raw material inbound information via Webhook
- Standardize and validate data format
- Calculate total cost and add records to the “Raw Materials” table in Google Sheets and Supabase
- Query existing inventory and update stock quantities (add new or update existing)
- Trigger low inventory alert emails when stock falls below predefined thresholds
-
Material Usage Request
- Receive usage request via Webhook, standardize and validate request data
- Record the request in the “Materials Issued” table
- Check current inventory to verify stock sufficiency
- Send approval request email with approval link to designated approver(s)
- Receive approval or rejection results via Webhook
- If approved, deduct inventory and update stock records
- If stock is insufficient or approval is denied, update request status accordingly
- Reassess inventory levels post-update and send low stock alert emails if necessary
-
Inventory and Approval Data Synchronization
- Bidirectional synchronization of inventory data between Google Sheets and Supabase database
- Real-time updates of request and approval statuses to ensure data consistency
