" Invoices issued before 01.04.2011 will be treated as per old rules that on the basis of payment received. As point of taxation rules are made applicable from 01.04.2011.
Further, second issue is highly disputed and the same is not discussed by the government or is not taken into consideration while drafting these rules. This is very common problem and is required to be solved. In this case service tax will be charged on whole amount of invoice i.e on rs. 100 or the amount of service tax which being paid on amount of bad-debt may be refunded or can be adjusted.
All the above explanations are of my personal view. So correct me, if i m wrong.

Yup , regarding first issue it has been clarified straight forward in notification only.. so it is clear.
that only those invocies issued after 01.04.2011, this rule will be applicable.
Regarding second issue there is no clear cut information but I think government policy is to tax all the taxable services at its value irrespective of its realization except in the case where the service are partially or not fully provided.
