You've got a point there, I thought I made a completley wrong move and 
assumed you would not need any additional info to direct me. I've made a 
file called userinvoice.php in fileadmin folder. This is it't content:
<?php
	class user_invoice {
		function store_invoice()
		{
			return 'works!';
		}
	}
?>
Then in page with id=3 i placed the following in it's setup field 
(page->edit page header->TSconfig):
page = PAGE
page.typeNum = 0
page.includeLibs.random_id_string56842798234 = fileadmin/userinvoice.php
page.20 = USER
page.20.userFunc = user_invoice->store_invoice

But 'works!' does not get displayed.
