Does Anyone Use Online Booking to Book Discovery Calls? Asking for a Friend :)

Hey guys

I was listening to Marcus Sheridan and he was talking about his usual stuff about making estimators, but he also talked about how after the estimator they book themselves on a call or for someone to come to the house. I'm a little protective of my time so I don't just go to every house that wants an estimate but I was wondering, if anyone is using the online booking feature like Calendly or any of those other meeting booking websites, to put their sales calls on their jobber calendar?

I'm trying to avoid having too many different software systems and I pretty much live out of my jobber calendar anyway.
