Error in service tax accounts head

Hi all,

I have recently joined in March a HR & Consultancy firm which deals into Manpower Recruitment and IT Software services. 

Recently I noticed that in January 2013 one Invoice being raised as Manpower Recruitment Agency being showed by our CA in the IT Software Services heads, and paid the Serice Tax accordingly.

Does it creates any problem.

Please advise.

Thank you,

Regards,
