one of my client has a restaurant business. .
he gave all bills related to restaurant food..
but he did not gave any bills related to online food orders (just like zomato,swiggy), he says these sales are not included in that sales ..

my queries
1) whether online order foods included in sales. .??
2) if yes, how much charge in gst??
3) Incase we don't want include in sales, what will be consequences??
