Vendor No-Show and Recovery Agent

Detects when a vendor misses an arrival window and immediately runs the recovery playbook: reschedule the same vendor, pull in a backup, and notify whoever depends on the visit, so a no-show becomes a same-day fix instead of a discovered-tomorrow surprise.

The Problem

The vendor never showed. You find out tomorrow.

No-shows cause last-minute chaos. Recovery is ad hoc.

What Changes

You find out within the hour, with a recovery ready.

Detects when a vendor misses their arrival window and triggers the recovery playbook - rescheduling, escalation, and backup vendor outreach - automatically.

Humans stay in control: Your coordinator approves the recovery action. The agent detects the miss and lines up the options. It removes the late discovery, not the decision.

The agent doesn't choose the fix. Your coordinator approves it. The agent catches the miss and lines up the options.

WHAT YOUR TEAM PROVIDES ONCE

  • Arrival signal - how the agent knows a vendor showed (check-in, status)
  • Grace window - how long past the slot before it counts as a no-show
  • Backup vendors - who can be pulled in per trade and area
  • Notification list - who needs to know a visit was missed
  • Recovery rules - when to reschedule vs replace
What happens day-to-day: A vendor doesn’t show. Instead of finding out when the turn is already behind, the agent catches the miss within the grace window, pings the vendor, and lines up a reschedule or a backup. Your coordinator approves a recovery plan the same morning.

WORKFLOW ENGINE (N8N)

Trigger - window timer
API - Check arrival
Branch - no-show?
Ping vendor
Wait - grace
LLM - Plan recovery
Notify + log

CONNECTS TO

PMS / scheduler (Yardi / AppFolio)Read: windows, check-ins. Write: reschedule
SMS (Twilio)Ping vendor, contact backup
Vendor directoryRead: backup vendors by trade/area
Notifications (Slack / email)Alert coordinator and waiting parties
WITHOUT PMS API

Agent infers a no-show from a missing status update on a shared sheet and proposes recovery for manual action. The playbook still runs.

WITH PMS API

Agent reads live check-in data, detects misses in real time, and writes the reschedule back. Best experience.

For the person who wants to build this agent step by step. Each node below maps to an n8n workflow node.

TRIGGERNode 1
Trigger - Window Passed
Timer set to each job’s arrival window end, plus the grace period.
Output: { job_id, vendor_id, window_end, unit }
APINode 2
HTTP Request - Check Arrival
Look for a vendor check-in, status change, or completion signal for the job.
Output: { arrived: true|false, last_status }
DECISIONNode 3
Condition - No-Show?
IF no arrival signal past window + grace → treat as no-show. ELSE → close, vendor showed.
Output: Branch: NO-SHOW (recover) or ARRIVED (close)
LLMNode 4
LLM - Plan Recovery
Decide reschedule vs backup using urgency, the job’s turn impact, and backup availability.
Output: { action, vendor_or_backup, proposed_time, reason }
You plan recovery for a vendor no-show.

Given the job, its turn impact, the vendor's response (if any), and BACKUP VENDORS, return:
- action: reschedule_same / use_backup / escalate
- vendor_or_backup: who to use
- proposed_time: earliest realistic window
- reason: one line

Prefer use_backup when the job is on a turn critical path and the original vendor is unresponsive.
Respond ONLY with valid JSON.

JOB: {job_json}
VENDOR RESPONSE: {vendor_response}
BACKUP VENDORS: {backups}
OUTPUT
{
  "action": "use_backup",
  "vendor_or_backup": "RapidFix Plumbing",
  "proposed_time": "today 2-4pm",
  "reason": "Original vendor silent; job is on B-214 turn critical path."
}
ACTIONNode 5
Notify Stakeholders
Send the coordinator the recovery plan to approve, and notify any resident or team waiting on the visit.
Output: Coordinator has a one-tap recovery decision; waiting parties informed.
ACTIONNode 6
Log No-Show
Record the no-show against the vendor’s performance history.
Output: No-show logged; feeds vendor performance scoring.
