Adjustment entry

first mension why they are changed their invoice

This invoce is related to AMC contract , so the AMC  for whole year ! ,

Sir,

   In this case first Reversed entry passed for old invoice and pass new value

 Second thing Service tax ur client paid when u paid their payment only so that is no probl;em.

Third thing TDS adjusted should be new bill. If new invoice value high or low balance should deduct and paid for Balanceing amount( Differnce of previous invoice and new invoice)

i agree with shivkumar
