Appointment Scheduling Software
Double bookings, no-shows, and a schedule that lives in one person's head. Knockio connects the calendar you already use — or gives you one — and books appointments straight from the job, checks who's actually free, assigns the right person, and reminds the customer so fewer of them ghost. Recurring visits for maintenance plans book themselves.
Schedule a DemoDoes appointment scheduling software for contractors need its own calendar?
Not necessarily. Knockio can connect to the calendar your team already uses, or you can use its built-in calendar if you don't have one yet. Either way you get real-time availability views, conflict-free assignment based on skill or territory, automated reminders for customers and crews, and support for recurring appointments — all tied directly to the job record.
