It fetches deal and contact data, generates a styled invoice, converts it into a PDF, logs it in internal systems, and sends it to the client.\n\nAfter sending, the system tracks payment status. If unpaid, it sends reminders and escalates overdue invoices automatically.\n\n### Setup steps\n1. Connect HubSpot trigger and API credentials\n2. Add HTML2PDF API key\n3. Set Google Sheets and Notion database\n4. Connect Gmail and Slack\n5. Update payment stage ID in IF nodes\n6. Activate workflow\n\n### Customization tips\n- Edit invoice design in Code node\n- Adjust wait durations for follow-ups\n- Add more reminders if needed"
