Why is the quoted price the same for different amounts of time?

The quotation price is calculated using a number of factors, one of the main factors is the cost of delivering the service. These costs can generally be split in to ‘variable costs’ & ‘fixed costs’. Variable costs include, fuel consumption, staffing & preparation. Fixed costs include, maintenance, insurance, car tax, income tax, cleaning, administration, marketing and storage etc. As the fixed cost is the largest proportion on the total cost of providing the service, there is sometimes isn’t any difference in the cost of providing the service for 1 hour or 3 hours, depending on the type of service. Furthermore, to ensure that the service provider can remain flexible to an existing customer, they may limit themselves to book one event per day.
