Let's say you sell a service/activity to a customer for €150.
Can you state something like this in your contact?
- An initial €150 payment must be payed upfront.
- An additional charge of €850 may apply afterwards at our own discretion. This may be for, but is not limited to, damages or other loses due to your usage of our service.
This is similar to my previous question: Can you refuse to pay back deposit at your own discretion? but differs in the fact that this would be an additional payment after the service is complete that is not required to be payed up front.
Answers for any jurisdiction would be useful, but preferably Ireland and the European Union
