Automate Vendor Contract Renewals & Reminders with GPT, Slack & Gmail

This intelligent n8n workflow automates vendor contract management by scanning a Google Sheet daily at 6 AM for contracts nearing expiration based on notice periods. It branches logic for auto-renew and manual renewal contracts: auto-renewals trigger simple Slack summaries to finance contacts, while manual ones use GPT-4.1 mini to craft personalized Slack messages, await approval (e.g., within 8 hours), and upon approval, generate and send professional HTML emails to vendors to initiate renewals.

Key benefits include preventing missed renewals, reducing manual tracking efforts, ensuring compliance with notice periods, and streamlining procurement processes. It saves hours weekly for finance and procurement teams by handling notifications, approvals, and communications automatically, with optional logging for audit trails.

Ideal use cases: Small to mid-sized businesses managing 10-100 vendor contracts, SaaS companies tracking subscriptions, or any organization with service agreements needing timely reminders. Easily customizable for other data sources like Airtable or databases, making it scalable for enterprise needs.
