With the “Mark slot as free” option, you can manually reopen any time slot in your

iClosed scheduler allowing multiple calls to be booked on the same time slot.

Available with Business subscription plans (see full pricing and feature breakdown here).

How to make slot available for another call

You can mark a slot as free in two ways.

From iClosed scheduler:

Go to AI Scheduler → Scheduled Calls - Upcoming calls
Click on the call to see call details
Click "Mark slot as free" button

From Google Calendar:

Click on the event in Google Calendar and select "Pencil" (edit) option
Change status from Busy to Free
Save changes to the event

Once you're done, you'll see on AI Scheduler → Scheduled Calls - Upcoming calls page that the slot was "Marked as free"

Pro tips

The “Mark Slot As Free” option is available only for calls that haven’t started yet.
Each newly booked call will automatically mark the slot as Busy to prevent additional bookings. If you want more leads to book in the same slot, just mark it as Free again.
Calls booked with the same host will use that host’s Zoom or Google meeting link. If two leads book the same slot, the alternate host should contact the second lead directly with his own meeting link.
Round-and-robin prioritization still applies:
- Higher-priority hosts are booked first.
- If hosts share the same priority level, the one with fewer upcoming calls gets the next booking.

How to block the slot back to busy

You can revert a freed-up slot back to Busy either in iClosed or Google Calendar.

From iClosed scheduler:

Go to AI Scheduler → Scheduled Calls - Upcoming calls
Click on the call to see call details
Click "Mark slot as busy" button

From Google Calendar:

Click on the event in Google Calendar and select "Pencil" (edit) option
Change status from Free to Busy
Save changes to the event

After saving, the “Slot Marked as Free” label disappears from your Upcoming Calls view.

Best practices

Increasing chances for better show-up rates on the call

This feature gives your team an additional safeguard against no-shows. Even if a lead confirms attendance, always have your setter or host reach out on the day (or day before) to reconfirm.

If a lead doesn’t respond, free up the slot so another qualified lead can book it.

Anticipating stronger leads

Use this feature when you have a weak or unqualified lead already booked, especially during ad campaign runs.

Freeing the slot lets a better prospect grab the same time, while giving your team a chance to contact the original lead and reschedule.

Handling "Big Whale" case

iClosed will automatically mark new bookings as Busy to prevent unlimited overlap, so if a top-tier lead books the same slot, you're safe.

If this happens, you should reach out to the earlier-booked lead(s) to reschedule or reassign them to other closers.

Plug & Play Multi-Booking

This type of multi-booking is manual, and works best for smaller teams or individual closers, and as such, is not the best option handling high-ticket offer with larger sales teams. Especially in regards of the handover from one closer to another if both leads showed up.

For larger teams, we advise the use of iClosed automated multi-booking for better coordination, transparency and overall result - more closed deals (read more about automated Multi-booking HERE). Here's why:

Slots will be automatically open for leads to double or triple book depending of the setup, so you can easily cherry-pick the best lead.
Settings are automated and advanced - per host, event and/or specific answer on the form.
Notifications will be sent to Slack channel as per your preference whenever:
- a lead joins waiting room,
- a lead is waiting for more than X minutes,
- invitee left the waiting room, or
- when no lead or host has joined waiting room X minutes past due
Any iClosed user can step in and seamlessly take over the call by generating his meeting link on the go.
