QUESTIONS TO TEST
1. Wash entitlement
Ask: Can the system distinguish a single wash, prepaid pack and recurring plan?
Demonstrate: Run one vehicle through each entitlement type and verify limits, expiry and duplicate-use prevention.
Observed result:
Follow-up:

2. Vehicle recognition
Ask: How are plate changes, rental vehicles and multi-vehicle household plans handled?
Demonstrate: Update a plate after a vehicle change. Confirm the old plate is revoked and the member can still resolve a mismatch at the lane.
Observed result:
Follow-up:

3. Payment recovery
Ask: What happens when recurring payment fails, retries or is cancelled?
Demonstrate: Simulate a failed renewal and a customer cancellation. Check customer notices and the exact moment lane access changes.
Observed result:
Follow-up:

4. Lane downtime
Ask: Can attendants issue, void or later reconcile a wash during an outage?
Demonstrate: Process a documented manual wash during a lane outage, restore service and reconcile the wash to the right member and site.
Observed result:
Follow-up:

DEMO SCENARIO (SYNTHETIC)
Test the membership at the point of service
1. Create a monthly plan with a defined wash limit, one member with two vehicles and a prepaid wash pack for a second customer.
2. Change one registered plate, then attempt a wash on the retired plate. Verify the attendant has a clear exception path that does not grant duplicate access.
3. Simulate a failed renewal and a tunnel interruption. Record a manual wash and restore the lane connection.
4. Reconcile the member’s access, transaction, refund or retry state across the customer account, site report and finance export.

MIGRATION
Plan a controlled data move
Inventory current memberships, renewal dates, wash limits, stored payment permissions, vehicle records, site assignments and outstanding disputes. Pilot one location through a billing cycle and lane outage scenario before migrating the full membership base.

A POSSIBLE FIRST BUILD
Lane access and recurring billing have direct customer impact. Define manual service and refund procedures, restrict payment access, disclose renewal and cancellation terms clearly, and review any vendor performance claims against your own baseline.
