Sale Order & Mail confirmation in PDF fomat

Dear All,

My requirement is like this, When user saves Sale Order a mail should go to Customer and Marketing Manager in PDF format.

As per my knowledge concerned I can achieve this requirement by working with output types.

Path NACE >Output types > Processing routines > [Medium] Simple mail > [Type] PDF or is it purely technical.

Please let me know is there any alternative solution.

Regards

SKumar
