background:
My firm is an online event planning platform where event vendors are registered and customer send us their inquiry. we connect customer and vendor. we don't charge customer. moreover customer also pays vendor directly. we collect commission on amount recieved by vendor. no other charges. we have no turnover till date. we don't have any payment responsibility and we do not collect payment online.

issues:
kindly guide whether we are ecommerce operator or not? Also whether we have to obtain compulsory registration in gst? any liability for deduction of tcs? whether our vendor are required to obtain gst registration (even with no turnover)?

please guide.
