This workflow reads your **asset register from Google Sheets** every morning, computes each item's warranty deadline and routes it through an escalation ladder:\n\n- **30 days left** → email the asset owner to decide: extend, replace or let it lapse. For assets worth ≥ 2000, an LLM also drafts a **vendor negotiation email** (saved as Gmail draft)\n- **7 days left** → urgent Slack alert + a Todoist task with a due date\n- **Already expired** → the register is updated to `warranty expired` so reports stay honest\n\n### 🔧 Setup\n1. Create a sheet with headers: `asset, owner_email, purchase_date, warranty_months, vendor, value, status`.\n2. Connect **Google Sheets**, **Gmail**, **OpenAI**, **Slack** and **Todoist** credentials.\n3. Select the sheet in **Read Asset Register** and **Mark As Expired**.\n4. Adjust the high-value threshold (2000) in **High-Value Asset?**.\n5. Activate — runs daily at **08:30**.\n\n### 💡 Why it's useful\nA single missed warranty claim on one broken laptop usually costs more than a year of running this workflow."
