The amount of the Sale transaction would represent that fee, whereas the amount of future recurring payments are defined in the Plan. If the recurring bill had an associated set-up or one-time fee use a Sale transaction. If you do not include a start date, the Recurring Engine uses the current date for the first payment.

In the Auth/Sale you simply include a element to initialize the Subscription using a named Plan and set the start date for the first recurring bill. You create a Subscription using either an Authorization or a Sale transaction. Subscriptions marry a customer order to a particular payment Plan and initiate the Recurring Engine to manage your future billing.
