The Challenge: High No-Show Rates & Delayed Paper Invoicing

Shift-based workforce agencies (security contractors, warehouse logistics, hospitality venues, and event management) face extreme operational friction: high worker absenteeism, manual phone-call rosters, and zero real-time verification of on-site arrival.

Paper timesheets created rampant billing discrepancies, took weeks to reconcile, and delayed worker payments—fueling workforce churn. Workerry needed a modern, automated system that could broadcast available shifts to qualified personnel, verify physical presence with GPS geofencing, and disburse payouts automatically upon shift completion.

Technical Architecture: Real-Time Telemetry & Split Payment Rail

We built Workerry using a dual-engine architecture. For workers on the ground, a high-performance React Native application (iOS and Android) delivers instant push notifications via OneSignal whenever matching shifts open nearby.

When a worker arrives at their assignment, background geolocation validates their device coordinates against the client's geofenced radius before enabling the clock-in toggle. On shift completion, a Stripe Connect payout rail automatically splits the client billing fee and releases immediate earnings to the worker's digital bank account, while generating a verified PDF invoice for the facility manager.

export async function verifyClockIn(workerLocation: LatLng, shiftId: string) {
  const shift = await ShiftRepository.findById(shiftId);
  const distanceMeters = Geofence.calculateDistance(workerLocation, shift.venueCoords);

  if (distanceMeters > shift.geofenceRadiusMeters) {
    throw new GeofenceError("Worker must be within 150m of facility to clock in");
  }

  const clockInRecord = await ShiftAttendance.recordArrival({ shiftId, timestamp: Date.now() });
  socketServer.to(shift.managerRoom).emit("worker:on-site", clockInRecord);
  return clockInRecord;
}
Zero Attendance Fraud • Sub-Second Dispatch Broadcast Haversine Geofence Engine

Key Systems Engineered

  • Geofenced GPS Timecards:

    Precision coordinate matching prevents clock-in fraud. Workers can only log hours when physically inside designated site boundaries.

  • One-Tap Shift Claiming:

    Real-time push notifications broadcast open shifts to verified staff based on proximity, certifications, and reliability score.

  • Instant Stripe Connect Payouts:

    Automatic escrow release and immediate bank deposit as soon as the venue manager digitally signs off on the timesheet.

  • Automated Client Invoice Generation:

    Compliant PDF invoices compiled with itemized hourly breakdown, tax line items, and facility codes generated with one click.
