What is the expected output? What do you see instead?

Issue is in your theme. Please refrain from using the_content filter in the 
meta title.

I certainly don't use wp_content filter in the Meta title.

I tried 5 different themes, always the same double output of the invoice.

Please try with default theme with all other plugins disabled. Then enable each 
plugin one at a time, note the plugin that causes Web Invoice to output twice. 
I'm sure it's hooking into the_content and printing the content.

Please update the issue with your findings.

There was a conflict with a setting in Headspace2 plugin. Fixed now, thanks.
