One form, one calendar
Start with the call you actually sell: a discovery call, an estimate, a consult. One form collects the name, the way to reach them, and why they want the time. One calendar holds the open slots.
Extra forms can be copied later. A second calendar on day one splits the leads before anyone is watching them.
Confirm it in writing
The booking should send a confirmation to the person who booked and to the person who will take the call. Include the time with the zone written out, not a bare abbreviation.
If the confirmation does not arrive, the calendar is not done, even if the slot looks blocked.
Then connect the pipeline
The booked person should already be a contact, and the opportunity should sit in the stage that means “call booked.” You should not have to type them in again after the form.
When that path works once, on a real address, the account has a spine. Build out from there.
