Automated SaaS Renewal Alerts with Slack & Google Sheets

Never miss another SaaS renewal deadline or pay for forgotten subscriptions again. This production-ready n8n workflow automatically monitors your contract portfolio in Google Sheets and sends progressive Slack alerts at 45, 30, 14, and 7 days before each renewal date—giving your team the advance notice needed to research alternatives, negotiate better terms, or cancel unwanted services.

What this workflow does

This isn't just another reminder bot—it's a comprehensive procurement intelligence system that runs daily at 9:00 AM to scan your entire contract database. The workflow reads your Google Sheets contract tracker (Contract Name, Vendor Name, Renewal Date, Annual Cost, Pricing URL, Status) and validates each entry for proper formatting and active status.

When contracts enter their alert windows, the system sends targeted Slack notifications with manual research checklists and tracks alert history to prevent duplicate messages. The multi-stage alert system ensures nothing falls through the cracks while giving finance and operations teams sufficient time for strategic decision-making.

Use cases

• SaaS portfolio management: Track dozens of software subscriptions across departments and prevent surprise auto-renewals
• Vendor negotiation prep: Get 45-day advance notice to research competitors and prepare renewal negotiations
• Budget planning: Receive cost reminders with pricing URLs to validate current rates against budget forecasts
• Team coordination: Centralized Slack alerts ensure procurement decisions involve the right stakeholders
