XYZ(Maharashtra) sold Control Panels to PQR(Maharashtra) by charging CGST + SGST. These panels were subsequently sold by PQR to ABC (Goa). Further, XYZ had done the installation of the panel at the Goa site of ABC on behalf of PQR and charged CGST + SGST to PQR in the service invoice towards installation. Is it correct or they should have charged IGST since the services were performed outside Maharashtra?
