Dear friends

One of my client who is a amanufacturer supplies machinery ( 28% GST Rate) and he only takes care installation and also do AMC if the machinery gets repaired so please clarify me

1. Whether Transaction value includes installation charges also?

2. What about if he collects transportation charges? same needs to be included

3. can he bill AMC in seperate bill (18% GST Rate)?
