There is a new simplified way to charge a Merchant Fee/Surcharge.  This can now be automatically applied when you select the Tender Type. 

You no longer need to apply the Merchant Fee to the booking on the Booking Fees page - this will be done automatically when you choose the Tender Type.

If you would like to use this feature,  please contact support@rentalcarmanager.com  and we can turn this new functionality  on for you.
