Work contact

Dear all,

we are newly engaged in Repair and Maint.( New Building, Old building, roof celling, and interior.) taking work orders.

we are a pvt. ltd. company and recently applied for service tax registration. 

My query is that we are providing services to individual Customer, Corporations, Builders and other association.

Please let me know how to charge Service Tax while issuing Invoice to Customer/Client as per providing services with Material and without Material.

Please suggest.
