Ason is a fully automated payroll engine that brings the expertise of a payroll specialist into software.
It processes payroll end-to-end - automatically, continuously, and fully compliant.
What payroll service providers typically handle manually - through checklists, expert knowledge, and repetitive processes - Ason performs automatically in the background.
Payroll Service - Expert Logic Built In
Ason validates input, flags missing data, and applies the correct calculation logic automatically - salary types, pro rata, retroactive changes, withholding tax, and country-specific regulations are all handled without manual intervention.
- Automatic tasks guide users through onboarding, changes, and period close
- Employees get self-service access (ESS) to their own payslips and data
- Unlimited payouts, multi-tenant and multi-lingual (DE, EN, FR, IT) out of the box
Additional logic such as collective labour agreements, ERP interfaces, or custom contract types is available on request.
How You Can Use Ason
Ason is designed to be flexible and adapt to your product strategy.
You can start with a standalone payroll solution or embed payroll into your platform - both options use the same underlying infrastructure.
The key difference is how payroll is exposed to your users:
| Mode | Description |
|---|---|
| Embedded | Payroll is part of your existing workflows and UI |
| Standalone (White-Label) | Payroll runs as a separate, fully branded application |
In both cases, users do not need a separate login. Ason can be connected to your Identity & Access Management (IAM), so users access payroll seamlessly with their existing account.
Embedded into your platform
Integrate Ason via API and make payroll a native feature of your product - your platform stays the single interface, while Ason handles calculations, compliance and processing in the background.
Best for: Platforms that want full control over user experience and deeply integrate payroll into their workflows.
See Embedded Into Your Platform for the full architecture, API flow and IAM integration.
Standalone White-Label Solution
Use Ason's ready-to-use UI and offer a fully branded payroll application to your customers, without building your own frontend or backend.
Best for: Fast time-to-market with minimal development effort, while still offering payroll under your own brand - or if you don't have a platform to embed Ason into.
See Standalone White-Label Solution for the full setup and IAM integration options.
Payroll is a stream of case changes. You report what happened. Ason does the rest.
