English to Spanish Marketing Finance (general) comercio

Good morning,

Would you be able to help me with a question I have about the word fees?

The following phrases show how it's used in part of text that appears in a web site when trying to purchase tickets.

Non-refundable fees
Refundable fees
The ticket price does not include venue fees
Buyer/Seller fees

I am not sure if the word fees can be translated as cargos, or cuotas, since I've seen it translated as honorarios, but that seems to not work as an added charge to a purchase. Somebody suggested 'tarifas' but I'm not sure of what would be the correct word to use in this cases.

I appreciate your help!
