an option to pay in full when booking for a trial package, without settign up auto pay

All our fully enrolled customers have Auto pay set up. However when a new lead books, we don't request them to set up auto pay, as it can put them off pursuing a trial class. Could their be a one off payment option for trial students to just pay online with their Credit card to book their trial (we offer a 3 week paid trial). Currently we have to manually follow up with every person that books a trial to get payment. Very messy and time consuming.
