Hello Guys, plz let me know if the location of the service provider is situated in the state of A and the location of Service receiver is in the state of B then which type of GST will be leviable. How and when supply of services will be termed as inter state or intra state.?
1. Technical and Professional Services. Where service provide occasionally visit the location of service receiver for site visiting etc.
2. Installation and Commissioning service where service provider send their team to the location of service receiver to execute the service.
3. Composite contract which involves supply as well as installations. To execute the same service provider will send their team to the location of service provider.
