08 July 2011 I have following query.
Because of internal problem of system, CST charged to the customer is in some cases 3% and in some case it is charged at 5%. This happened in the month of Jan 2011, march 2011 and June 2011.
So my query is what is risk in this and now what should be done?
Please reply urgently.

08 July 2011 you have to file return with 2% ( correct cst) and claim refund of excess CST paid,

you have to issue credit note to client ( buyer) for diff of CST
