Capabilities

Six things the booking engine does well.

📅

Booking pages

A branded page for every service, embeddable on any website

🔔

Automatic reminders

Confirmation, day-before and hour-before texts and emails

🔄

Two-way sync

Google, Outlook and iCloud calendars stay in step, both directions

👥

Team scheduling

Round-robin, per-staff availability, buffers and daily limits

💳

Deposits at booking

Take a card or a deposit through Stripe before the slot is held

🤖

AI books by phone

The AI receptionist reads the same calendar and books live, 24/7

📵 No-shows

Built for people who forget they booked.

Every booking triggers a confirmation, a reminder the day before and a reminder an hour before, each with a one-tap reschedule link. If someone cancels, the slot reopens on your booking page and the AI can offer it to the next caller. If you need a deposit to hold the time, Stripe collects it before the slot is confirmed.

Where it fits

One calendar behind every channel.

The same availability powers your website widget, the booking link in your texts and emails, the live chat on your site, and the AI receptionist on your phone line. Book a slot in any of them and it is gone from all of them. Reminders go out through the built-in SMS and email engines, so there are no reminder credits to buy and no second tool to log into.

The AI receptionist booked 14 appointments in my first week without me lifting a finger. This is pure revenue I wasn't seeing before — and it never sleeps.

After-hours calls used to go to voicemail. Now the AI answers every one, qualifies the case, and books a consult. Booked 11 new clients last month from calls I would've missed.

FAQ · Questions

Things people ask.

Does it sync with Google Calendar and Outlook?
+
Yes. Google, Outlook and iCloud calendars sync in both directions. A meeting you add in Google blocks the slot on your booking page, and a booking made on the page appears in Google within moments.
Can clients reschedule or cancel on their own?
+
Yes. Every confirmation and reminder carries a reschedule link and a cancel link. Changes update your calendar and reopen the slot automatically, and you can set a cut-off so nobody cancels an hour before.
Can I take a deposit or full payment when someone books?
+
Yes. Connect Stripe and any service can require a card on file, a deposit or the full fee before the slot is confirmed. Payments land in the same invoicing you use for everything else.
Does the AI receptionist book into the same calendar?
+
Yes. The AI receptionist reads live availability from the same calendar, offers open times on the call, books the slot and sends the confirmation text before the caller hangs up.
Can a team share one booking page with round-robin?
+
Yes. Add as many staff and calendars as you need at no extra cost. Round-robin distributes new bookings evenly, or you can let clients pick a specific person. Each person keeps their own availability, buffers and daily limits.
Can I put the booking widget on my existing website?
+
Yes. Every calendar has a hosted booking page and an embed code that works on WordPress, Squarespace, Wix or any site that accepts an iframe. If we build your website, the widget is already on it.
What reminders go out, and can I change them?
+
By default a confirmation on booking, a reminder 24 hours before and a reminder one hour before, by text and email. Timing, channel and wording are all editable in the workflow, and you can add a follow-up after the appointment to ask for a review.
Is appointment booking included in every plan?
+
Yes. Booking pages, calendars, reminders and calendar sync are included in every TheBigBot plan with no per-user fee. The only usage cost is the SMS reminders themselves, billed at the carrier rate on the usage fees page.
