Three QR codes.
Three audiences.
One platform.
Vendors check in. PMs validate timesheets. Buyers self-register at the model home. All from a scan. No app install. No login. Every event audit-trailed.
Vendor Jobsite QR
Scan on arrival. We log everything.
Every community and home gets its own unique QR code. Vendors scan with any phone — no app install, no Cornerstone login. GPS coordinates, timestamp, and weather conditions are captured automatically. Check-in and check-out times build a verifiable hours-on-site record.
- GPS + timestamp + weather captured on every scan
- Hours-on-site tracked automatically (check-in → check-out)
- Photo upload at check-in — up to 10 photos per visit
- Configurable safety acknowledgment per community
- Worker headcount log for crew sizes
- Webhook events: vendor.arrived, vendor.departed
- Printable 11×8.5" signs auto-generated for every home
Community / PM QR
Timesheets that prove who was on-site.
PMs, permitting agents, and inspectors scan at the construction trailer when they arrive. GPS-validated presence logging feeds the timesheet system — actual on-site presence is aligned below the timecard grid so managers can validate reported hours.
- GPS-validated presence logs
- Timesheet integration — actual presence vs. reported hours
- Stops "I was on-site all day" entries that don't match the GPS record
- Per-community QR codes for multi-subdivision builders
- Inspector workflows — log site visits with photo evidence
- All scans attributable to a specific user account
Sales Model Home QR
Goodbye, paper sign-in sheet.
QR code at every model home entrance. First-time visitors enter their info on their own phone. Returning visitors are recognized automatically: "Welcome back!" Every scan creates a Lead tied to the community, with instant in-app and email notifications to the sales agent.
- First-time vs. returning visitor recognition
- Captures name, email, phone, "How did you hear about us?"
- Lead record auto-created and tied to community
- Sales agent gets instant in-app + email notification
- Leads dashboard grouped by community with status tracking
- No more paper sign-in sheets to retype on Monday
- Foundation for nurture sequences and follow-up automation
Why no one else has this
Home builders manage three workflows that most software treats as separate problems: field operations, internal time tracking, and sales lead capture. We built one QR-based check-in primitive and pointed it at all three.
GPS audit trail
Every scan is geotagged. Cuts disputes about who was where, when.
Weather logged
Conditions captured at scan time. Dispute pour-day delays with the receipts.
Photos & webhooks
Vendors upload photos at check-in. Webhooks fire to your automation stack.
Vendor Activity Map
Every QR scan becomes a pin. Live Google Maps view of every vendor and PM check-in across every community. Filter by date, filter by vendor. See who's on-site right now — refreshes every 30 seconds.
Same live map on desktop, tablet, and phone. Pull it up from the truck, the jobsite, or the dinner table.
- Real-time pins for vendor and PM check-ins
- Stat cards: communities, on-site count, unique vendors today
- Activity feed sidebar of recent scans
Have cameras already? Skip the QR.
Cornerstone's AI Jobsite Camera Events feature accepts webhook events from any camera, doorbell, gate sensor, or AI vision system — Verkada, Ring, custom IP cameras, anything that can fire an HTTP POST. When a vendor is detected on-site, the matching scheduled task auto-flips to In Progress. No QR scan required.
