[support] Payment module

[Roger]

Is there a small use payment module not so comprehensive and complex as 
Ubercart.

We  need  something that allows people to book and pay for events a 
couple of times a year and pay for books ordered through the year and at 
the events.

But we need to audit every thing to Australian accounting standards so 
we will need to create print out for the accountant or hopefully save 
the data into a spreadsheet format that they can use.

Can someone point me in the right direction
thanks
Roger
