Hi Bill,

You have the option of Paypal enrolment in Totara:

Home > Administration > Courses > Enrolments

http://docs.moodle.org/19/en/Paypal

Coursemerchant may also be worth a look http://www.coursemerchant.com/course-merchant/

One of our Partners talked about using this for a client at the Totara conference in September http://www.slideshare.net/totaralms/totara-conference-presentationwebanywhere

Not sure about a Financial Management module, do you have any more info/requirements?
