Logistics
Goods moving, domestically and across borders: trips and legs, consignments, lanes and rate cards, customs formalities, and driver cash settled on return.
A lane is a pricing qualifier, not an entity
"Alexandria to Tripoli" is a value on a rate-card line, in the same table that holds an hourly inspection rate. That is why a new haulier needs configuration rather than a new data model.
Border crossing, with its disbursements
Duties, clearance and recoverable disbursements are charged to the trip at cost and re-invoiced as they were paid, in the currency they were paid in.
Driver cash
An advance issued before departure and settled afterwards against real documents, so the accountant knows what each driver holds now rather than at month end.
Waiting, detention and free time
Waiting time, detention, demurrage and container free-time terms are billable lines computed from recorded timestamps rather than from somebody’s recollection.
Roads and boundaries, when configured
Distances and administrative boundaries come from a separate geographic database where one is provisioned, and fall back to great-circle distance where it is not — an installation without it loses a feature, not a screen.
