DEMO SCENARIO (SYNTHETIC)
Run an emergency repair and a maintenance visit
1. Create a customer with two properties and units; open a no-heat call at one address.
2. Dispatch a technician, revise the window and check customer and field updates agree.
3. Present repair options, approve one, record a part and reconcile estimate, cost and invoice.
4. Complete one maintenance visit and schedule the next; verify remaining visits and renewal status.

MIGRATION
Keep agreements attached to equipment
Request customers, service locations, equipment identifiers/history, notes, estimates, work orders, invoices, parts, active agreements and future visits. Check whether serial numbers, warranties, attachments and entitlements remain linked. Reconcile open calls, unbilled work and due visits; define the overlap process and retain a readable archive for older records.

A POSSIBLE FIRST BUILD
A custom project could join website requests to the dispatcher’s existing system. Do not replace equipment records, field execution, payments or maintenance billing until a full job passes mobile, accounting, failure and support tests.
