This n8n template demonstrates how to create an automated construction progress notification system for real estate companies. The workflow triggers daily at 8:00 AM IST to check a Google Sheet for contractor construction reports, automatically processes the data, and sends comprehensive project updates to buyers via email and WhatsApp. Perfect for real estate developers wanting to maintain transparent communication with buyers and ensure timely project status updates.
Good to know
- Daily automated monitoring ensures no construction updates are missed
- Multi-channel communication (Email + WhatsApp) reaches buyers through their preferred method
- Smart filtering system only processes today's reports for relevant updates
- Comprehensive logging tracks all notification activities for audit purposes
- Built-in alert system notifies administrators when contractors fail to submit reports
- Handles multiple projects and contractors simultaneously without data conflicts
How it works
Daily Monitoring Workflow
- System triggers automatically every day at 8:00 AM IST to check for new construction reports
- Google Sheet configuration is set with Sheet ID, sheet name, and today's date for filtering
- All construction data is read from the designated Google Sheet containing contractor submissions
- Advanced filtering isolates only today's reports based on the Date column for processing
Report Processing Workflow
- System checks if any construction reports were submitted for the current date
- If reports are found: Detailed notifications are prepared and sent to all registered buyers
- If no reports are found: Alert notifications are sent to administrators about missing submissions
- All project data is compiled into comprehensive summaries with progress percentages and status updates
Notification Distribution Workflow
- Email notifications contain detailed construction summaries with all project information
- WhatsApp messages provide concise updates with key progress indicators and status
- Messages are personalized with project names, completion percentages, and contractor details
- Multiple recipients receive notifications simultaneously through both communication channels
Activity Logging Workflow
- All notification activities are logged with precise timestamps and recipient information
- Success logs record project count, recipient numbers, and delivery confirmation
- Warning logs capture instances when no reports are found for administrative follow-up
- Complete audit trail maintains compliance and tracking for project management
