What our HR management system does

An HR management system (HRMS) is the central record for everything to do with your people: who they are, where they work, what they are entitled to, when they are off and how they are performing. Syntrix HR brings employee records, leave, attendance, onboarding, performance and payroll data into one platform, with a self-service app so employees and managers handle routine requests themselves.

The result is less time chasing forms and more time spent on the parts of HR that need a person.

Who it is for

• Businesses of 50 to a few thousand employees that have outgrown spreadsheets and shared folders.
• Multi-site and shift-based organisations — retail, hospitality, healthcare, logistics — where attendance and rotas matter.
• Schools and colleges, often alongside our school management system, for staff records, leave and cover.
• Groups with several entities that need consistent policies with local variations.

Key capabilities

Employee records

A single, secure profile per employee: contracts, job history, salary history, documents, emergency contacts, right-to-work checks and certifications with expiry reminders.

Leave and absence

Configurable leave policies, accruals and public holidays by location. Employees request leave on their phone, managers approve with a view of team cover, and balances update automatically.

Time and attendance

Clock in and out by mobile (with optional geofencing), kiosk or biometric device. Hours, overtime and lateness feed payroll and reporting.

Onboarding and offboarding

Checklists assign tasks to HR, IT, managers and the new starter, with document collection and e-signature, so day one is organised. Leavers follow a matching offboarding flow.

Performance and development

Objectives, review cycles, 1:1 notes and training records, configured to your own review model rather than a fixed template.

Payroll data

We do not replace your payroll provider; instead the system produces clean, approved payroll inputs — hours, leave, starters, leavers and changes — and exports them each period.

Implementation

We configure your organisation structure, policies and approval chains, migrate employee data, connect payroll and identity systems, then launch self-service to managers first and employees second. Where HR sits inside a wider operations platform, it can share data with our ERP software. Automating HR workflows such as approvals and document generation is covered by our business automation service.

Data protection

HR data is among the most sensitive a business holds:

• Field-level permissions so salary, medical and disciplinary data is restricted to authorised roles.
• Encryption in transit and at rest, multi-factor authentication and single sign-on.
• Full audit trail of who viewed or changed sensitive records.
• Configurable retention rules and subject-access export to support GDPR and local data protection law.

2. Set up leave policies, holiday calendars and working patterns.
3. Migrate employee records and opening leave balances.

    ASP.NET Core is our default framework for secure web applications and REST APIs: fast, cross-platform and well suited to complex business logic and integrations.

  • Angular

    Angular development for large, form-heavy enterprise applications where consistent structure, strong typing and long-term maintainability across teams matter most.

  • SQL Server

    SQL Server and Azure SQL power many of our ERP, POS and reporting systems, offering strong transactional integrity, rich tooling and tight integration with .NET.

  • Microsoft Azure

    We design, build and run applications on Microsoft Azure: App Service, containers, Azure SQL, Functions and Azure OpenAI, with security and cost control built in.

What our clients say

• We used to lose half a day's takings every time a store's broadband went down. Since the new tills went in, outages barely register, and head office can change a price at lunchtime and see it on every shelf-edge promotion by the afternoon.

• Parents now have one app instead of four, and our office teams have stopped spending Monday mornings chasing absence calls. The migration was the part we worried about most, and the trial runs meant there were no surprises on go-live day.

• The assistant resolves the repetitive how-do-I questions and hands everything else to us with a proper summary. Our agents spend their time on the tricky tickets now, and customers get answers at 2am without us adding a night shift.

FAQ

Frequently asked questions

• Does the HR system run payroll?

  It prepares payroll rather than replacing your payroll provider. Approved hours, leave, overtime, starters, leavers and pay changes are exported each period in the format your provider needs, which removes most manual re-keying and errors.

• Can employees use it on their phones?

  Yes. The self-service app for Android and iOS lets employees request leave, clock in, update personal details, view documents and complete onboarding tasks. Managers can approve requests from the same app.

• How is sensitive employee data protected?

  Access is controlled by role and down to individual fields, so salary or medical details are visible only to authorised people. Data is encrypted in transit and at rest, and every view or change of sensitive records is logged.

• Can it handle different leave rules for different countries or sites?

  Yes. Leave policies, accrual rules, working patterns and public holiday calendars are configured per entity, location or contract type, so each employee automatically follows the correct rules.
