I agree with Mr.mangesh lokre. but, this will not help in many case, for example,you have two or more manufacturing units & you are hiring some technical expert and their service is utilized for all plants and bill addressed to any one unit, How will you deal with CENVAT aspect.
Therefore, if you have two or more factory, it is appropraiate that you seek for Registration as Input service distributor at your H.O. with all factories as units to which CENVAt credit is intendented to be distributed . In that case, You get all invoices in name of HO and distribute credit to unit where credit is required by following certain procedural aspects. This will help in instance utiliation of credit of SErvice TAX only.
