High complexity⏰ Scheduled16 nodes🏷️ Project Managementby Rahul Joshi

Overview

πŸ“Š Description Ensure suppliers never miss a follow-up by automating overdue purchase order tracking and scheduling. πŸ“¦β° This workflow checks Airtable every weekday morning for open POs older than seven days without scheduled follow-ups, generates Google Calendar events, updates Airtable with the follow-up link, and sends notifications to your team via Slack and Gmail. It centralizes supplier management and eliminates manual reminders, helping operations teams stay on top of aging purchase orders
