I agree with Alex. Don't see the point of creating a class instance (as niels suggested) when you can just do this:

def my_view(request, id):
    customer = ..
    invoice = ..
    date = ..
    return render_to_response('xxx,html', locals())

If you want a performance reason, dotted lookups are slower.

If you want a maintenance reason, this is fewer lines of code, even more readable, and one fewer unnecessary structures.
