The overwhelming majority of businesses won't switch their booking system unless they have a truly compelling reason. A large proportion of small businesses still use pen-and-paper to manage their bookings and have no intention of changing.
People would have said the same about payment systems before Strype came along....
Here is an example of who I think you’d have a hard time convincing: I’ve been going to the same hair stylist for about 22 years. Her clients have followed her as she moved around salons in Cupertino. She’s busy enough that many of her clients (including me) sit down at the beginning of the year and book an entire year’s worth of appointments. She only accepts checks or cash.
She’s popular enough that she has felt no market pressure to start accepting payment cards, and certainly has not had any trouble staying busy.
I think there’s a huge chunk of small/single-person businesses that will continue to do things using paper simply because they don’t want to change and they have enough clients that they don’t need to. Once they retire/expire they may be replaced by people that are more amenable to such things.
I think she’d be open to the idea, it’s not like she’s actively refusing business. Taking some reservations from a computer voice is a lot less change and (more importantly), it’s not change she has to initiate.
