The GoCorp service checks for employees' limits vs. the cost of the trip at the point of booking. Charges like ERP / Toll fees or GoTaxi's actual metered trip fare are calculated after the trip has been completed and may exceed the employee's spend limit. In such cases, if the employee's limit is not sufficient to cover the additional cost of the trip, the balance amount is charged directly to the company and will appear under the trip details on the 'Trip history' page.
