Automate SaaS Renewals with Slack Alerts & Google Sheets

Never miss another SaaS renewal deadline again. This production-ready n8n workflow automatically monitors your contract portfolio in Google Sheets and delivers strategic Slack alerts at 45, 30, 14, and 7 days before each renewal. Stop overpaying on auto-renewals and start making informed procurement decisions with advance notice.

What this workflow does

This isn't a generic reminder system—it's a procurement intelligence automation designed for finance and operations teams who manage multiple SaaS contracts:

• Daily monitoring: Runs automatically at 9:00 AM via cron trigger, scanning your entire Google Sheets contract database
• Smart validation: Checks contract names, ISO date formats, pricing data, and URLs before processing alerts
• Multi-stage notifications: Sends progressive Slack alerts at four critical intervals (45, 30, 14, 7 days) with manual research checklists
• Duplicate prevention: Tracks alert history to avoid notification spam while ensuring no renewals slip through
• Structured data tracking: Reads contract details including vendor names, renewal dates, annual costs, and pricing URLs from columns A-F

• Research alternatives before auto-renewal kicks in
