English to Czech Bus/Financial Law: Contract(s) Contracts

Dobrý den, mám dotaz na dva termíny.

Celá věta k prvnímu - At the Lessee’s request, the Lessor may intervene to perform start-up operations and/or dismantling operations at the end of the rental period. At that moment, a contradictory field report will be drafted to describe the operations undertaken.

Portal-to-Portal - hledám český ekvivalent - celá věta - Lessee will be invoiced from the time the equipment leaves the depot until the equipment is returned to the depot (“Portal-to-Portal”). Nebo to nechat nepřeložené?

Děkuji všem předem a přeji hezký večer.
