Hello,

For each service that is not handled by us directly, ex transfer, ski pass...etc we are adding a handling fee 5% of the total of a certain service this is applicable to.

My question is how to set up this in mews so that once handling fee is to be added into the bill to automatically calculates 5% of the price of the product refers to vs how we do now, calculate manually and then place it on the guests bill. Thank you
