PayPal is one of the recommended online payment transaction solutions that DIS recommends. We recommend this for many reasons - largely due to ease of use, positive feedback from our customers that use Paypal, lower fees/costs and overall high satisfaction of PayPal from world wide users.
Several Site Manager and DIS application tools can be integrated very easily with your PayPal account. But you must first have an established PayPal account. As a third party service (not a service DIS provides), you'll need to do this yourself.
Here are some of the most popular links to get you started:
Once you have your account started, the DIS Support Team can assist you with applicable tool property setup.
