Sometimes these fees are covered by your payment processor.

You must have a payment processor set up before you can start using ThinkReservations. ThinkReservations uses the payment processor to validate the credit card information submitted through your online booking engine. Proper validation is required before a reservation can be made online, regardless of your deposit policy.

If you are an existing ThinkReservations customer considering switching payment processors, please note: Switching the processor account will result in all retained credit cards being lost. This is because the retained cards are actually stored with the gateway or processor, not in ThinkReservations. You could either reach out to future guests to obtain the credit card info again or simply wait until the guests arrive for their stay. Please reach out to ThinkReservations when you are ready to switch as we need to make the changes for your account.
