Why does a business need a website?
Because search sends strangers to websites, not to social accounts; because a stranger deciding whether to trust you looks for one; because payments, bookings and orders need somewhere to happen that does not depend on one person answering a chat; and because a site is the one channel you own rather than rent. If your customers all come by referral and orders fit in a chat, you may not need one yet. The moment strangers start searching for what you do, you do.
