No you cant download COSA Exe file by yourself from Net, it would not work, for installation of COSA software either you have to reach nearest NIC Centre for, designated agency for your Zone, who will install the soft ware to make you acquainted with the Software and procedure to implement
Is there any new order from F.D. about COSA ??? What will happen if any office may be unable to to implement COSA in due time i.e. PAY BILL OF JULY’12 ?? Is there any option to submit MANUAL PAY BILL for the month of JULY’12 to the Treasury Office??
