Non- comprehensive amc

Hi All,

I have an invoice with me wherein the subject is "Non-Comprehensive AMC (CCTV)". The Service provider is liable for Service Tax. However 12.5% VAT is charged on the whole amount. No Service Tax is charged. I have attached the Invoice. Kindly have a look at it and advice me whether the Tax applied is right or should Service Tax be applied instead of VAT. and what if it involves Service and some materials for providing the service? And what does NON COMPREHENSIVE AMC mean? Kindly answer with reference to the Invoice attached.

Thank you... :)
