Add-on rates are important additional fees that can be added to any service provided by your company. These fees may be required in certain situations or areas when offering transportation services to your clients. Examples include fees for airports, parking, and security gates. The add-on rates are automatically applied when customers request a booking through the front-end form or when dispatchers make a booking on their behalf on the selective service type. This saves time for your employees and reduces the chances of mistakes in rate calculations. It also ensures that customers are aware of these extra charges when making a booking, giving them the option to proceed or choose an alternative.
