Facial recognition and geo-tagged book-on/book-off give you verified proof of attendance. Clients get full transparency, and you get complete control over your workforce.

Payroll & Invoicing Automation

Link shifts and attendance directly into payroll and invoicing. Slash admin hours, eliminate costly errors, and speed up cash flow — because if you’re not using Arez, you’re leaving money on the table.
Payroll & Invoicing Automation
1. Seamless Payroll Integration
All approved shifts and timesheets flow directly into payroll. Arez reduces manual data entry, eliminates duplicate records, and ensures guards and subcontractors are paid accurately and on time.

This means less time on paperwork, fewer mistakes, and peace of mind for clients who demand full transparency.
