QUESTIONS TO TEST
1. Unit and fleet history
Ask: Can work orders, inspections and PM dates attach to the exact truck, trailer or equipment unit?
Demonstrate: Create two similar units and check that complaint, repair history, meter and next maintenance date stay separate.
Observed result:
Follow-up:

2. Estimate and authorization
Ask: Can a shop distinguish the inspection finding, recommended work and customer-approved repairs?
Demonstrate: Document a finding, send an estimate with two work items and authorize only one. Keep the other off the final invoice.
Observed result:
Follow-up:

3. Parts and sublet costs
Ask: Can ordered, received and returned parts plus outside work reconcile to the job?
Demonstrate: Backorder one part and record a sublet service. Check promised completion, parts margin and invoice lines.
Observed result:
Follow-up:

4. Technician and PM schedule
Ask: Can staff see bay/technician capacity and the fleet unit’s upcoming maintenance?
Demonstrate: Schedule a repair with an assigned technician, then create the next PM reminder and test a conflicting bay slot.
Observed result:
Follow-up:

DEMO SCENARIO (SYNTHETIC)
Run a fleet truck repair with a parts delay
1. Create a fleet customer with two similar trucks and open a repair order for a no-start complaint on one unit.
2. Record inspection findings and send a multi-line estimate. Authorize one repair and defer another.
3. Order a part that is unavailable and send outside work to a sublet provider. Update the customer ETA without closing the job.
4. Complete the repair, reconcile technician hours, parts, sublet and payment, then schedule the next PM reminder on the correct truck.

MIGRATION
Plan a controlled data move
Import fleet accounts and units, open work orders, estimates, inspections, part records and locations, technician assignments, PM intervals, unpaid invoices and accounting mappings. Physically reconcile vehicles in bays and units already promised to customers before dispatching new jobs.

A POSSIBLE FIRST BUILD
Shop-management software does not determine whether a repair is safe, compliant or technically correct. Technicians and qualified staff remain responsible for inspections, repair decisions, authorization and required records.
