Synerion is workforce management software built for organizations that need reliable, configurable, and technically sound tools to manage employee time, scheduling, and labor costs. Unlike lightweight apps or rigid legacy systems, Synerion focuses on precision and adaptability. Time can be captured through biometric clocks (fingerprint, facial recognition), proximity or card readers, mobile devices with geofencing, web browsers, or tablet kiosks. Each punch is validated in real time against rules for overtime, shift differentials, union agreements, and custom premiums, reducing downstream payroll exceptions. Offline support with automatic sync ensures data is never lost. For developers and IT teams, Synerion offers a modern REST API, webhook support, and more than 100 prebuilt connectors to leading payroll, ERP, and HR platforms. Integration isn’t a CSV shuffle — data flows bi-directionally with support for SSO via SAML and OAuth. Audit trails, role-based permissions, encryption in transit, and configurable data-retention policies provide the security and compliance required by enterprise IT. Managers gain centralized scheduling tools that can auto-assign shifts, handle rotations, balance skills across teams, and highlight coverage gaps. Labor allocation down to job, project, or cost center levels makes reporting and charge-backs straightforward. Finance and operations teams get dashboards that track hours, overtime, and costs in real time, with exportable audit-ready reports.
