Built by people who lived the problem.
DayO Book started with our dog Dayo, more than 40 states, and years of calling around to book boarding, grooming, and vet visits in every new city. We built the tool we wished every business had.

How much does it cost?
Nothing to start. You pay $0.50 for each successful booking and nothing else. If nobody books, your bill is $0, and a booking cancelled before the appointment time is never charged.
Do my customers need an account to book?
No. They can book as a guest in under a minute, or sign in to keep their details for next time.
What kinds of businesses is it for?
Any business that runs on appointments: salons, spas, fitness studios, medical and dental practices, pet care, restaurants, home services, and more.
Can I run more than one business or location?
Yes. One account can run as many businesses as you need, each with its own bookings and calendar.
How long does setup take?
Most businesses are live in minutes. You pick your industry, we pre-fill the details, and you adjust what you want before sharing your link.
