Synerion is workforce management software engineered for organizations that require accuracy, configurability, and long-term reliability when managing employee time, scheduling, and labor costs. Instead of forcing businesses into rigid templates or relying on brittle spreadsheets, Synerion adapts to the complexity of real-world operations. Time can be captured through a range of devices — biometric clocks (fingerprint, facial recognition), proximity or HID card readers, mobile apps with geofencing, browser-based portals, or tablet kiosks. Each punch is processed in real time and validated against configurable pay rules, including overtime, shift premiums, union agreements, step rates, and project-based allocations. This reduces payroll errors at the source and eliminates costly manual reconciliation. Offline mode with automated sync ensures no time data is lost, even during outages. Managers gain tools to design complex schedules with rotations, shift balancing, and skill coverage checks, while automated alerts notify them of gaps, overtime risks, or missed punches before they become problems. Finance and operations teams benefit from configurable dashboards and audit-ready reports that provide transparency into hours, costs, and labor allocation at the job, project, or department level. This gives leadership confidence in their workforce data and a clear view into labor’s impact on profitability. Deployment is handled directly by Synerion’s in-house specialists rather than outsourced contractors, ensuring faster discovery, accurate configuration, and smoother go-lives. Customers can choose Synerion Agile, a quick-start package for fast adoption, or Synerion Enterprise, a fully configurable system capable of supporting highly complex requirements. With 35 years of experience and thousands of customers across manufacturing, healthcare, logistics, and government, Synerion combines enterprise-level flexibility with mid-market accessibility.
