If you look at page 15 on the investor presentation concerning the booking.com integration http://nzx-prod-s7fsd7f98s.s3-websit...403/346257.pdf it says "Serko is currently seeing over 1,300* of SME business customers per day activate** on the new platform, during this phase of migration."
Darren said on the investors call that SME business customers usually make between 3 to 12 bookings per year. I see this as a positive sign for the future.
