Real bookings. Not just messages.
Della reads your live calendar, finds open slots, confirms with the caller, and writes the booking, all during the call. Bookings appear in Google Calendar, Outlook, or your Della calendar within seconds. No email back-and-forth, no double-booking.

Most 'AI booking' tools just take messages.
When a caller asks 'can I get in Friday at 2?' the worst answer is 'I'll have someone get back to you.' By the time you call back, they've booked elsewhere.
Della reads your live calendar (Google, Outlook, Apple, or built-in Della calendar) and quotes real availability in real time. When the caller picks a slot, Della writes the booking immediately, visible to your team within seconds. Conflict checking, buffer time, multi-staff routing, all handled automatically.
What Della does on the call.
Live availability
Della reads the same calendar your team sees. No 'sync delay,' no stale slots offered.
Writes bookings during the call
Della writes the booking before the caller hangs up. Booking appears in your calendar within seconds.
Conflict-aware
Della checks every slot against existing bookings, blocked time, and staff availability. Never double-books.
Buffer time + duration rules
Set 15-min buffers between appointments, different durations per service, prep time per staff member. Della respects all of it.
Multi-staff routing
Caller asks for Sophie? Della books with Sophie. No preference? Della offers the next available slot across the team.
Auto reminders
Booked appointments trigger SMS + email reminders 24h and 2h before. Reduces no-shows.
Call from your phone and try it: book a time, ask a question, switch languages. She tells you she is an automated assistant, then does the job.
