Pendulum serve

My pendulum serve is rarely crossing the net. i have a pre-made bat which i have been using for about a year. please help me out.

Hi Aryan,

Try to push the bat more forward on contact.  Also hit the ball from a little higher.  This will mean that you need to get your arm up higher as well at the start of the serve.  This will get you to hit the ball form a higher point.  Hit the ball more into the table to get more bounce on it.
