YoutilityKnock is the field companion for door-to-door sales and canvassing teams. Built for reps who work neighborhoods all day, it puts your territory, your leads, and your numbers in one fast, offline-friendly app. • Map your turf — see homes around you, drop pins, and confirm a knock right on the doorstep with on-site location. • Capture leads in seconds — record the homeowner, the disposition, and notes without losing momentum. Attach a photo of the home or a utility bill. • Work your territories and shifts — know where you've been, what's left, and who's on your team. • Stay in sync — leads and activity sync to your company automatically, and queued work survives a dead zone thanks to offline support. • Built-in hierarchy — managers see their team's activity; reps see their own. YoutilityKnock accounts are provisioned by your company administrator. If you don't have a login yet, contact your admin. Location is used only while the app is open, to show nearby homes and confirm on-site knocks — there is no background tracking.
