Hello,
There is no straight jacket answer to your question as the entire business model has to be understood first before taking a call because there is more to it than just GST.
For GST sake, it is better if the operating entity raises invoices and collect fees than the OPC.
Trust this clarifies your query.
Feel free to call / get back in case of further clarifications.
Thanking You.
Regards,
