Regulation

Regulations are the fuel of the Payroll Engine; they

• Provide external data with lookups
• Capture company and employee data with cases
• Calculate employee salaries
• Build data reports

By separating the business rules with regulations from the backend server, technically skilled payroll professionals can develop payroll applications in an integrated manner.

Usage

The Payroll Engine is a .NET based application and can run on Windows or Linux. The backend server requires a SQL Server database (Setup).

The following topics are relevant to the use of the engine

• Regulations
• Time data
• Cultures
• Calendars

To use the engine, proceed as follows

1. Setup
2. Basic Payroll Example
3. Advanced Payroll Example
4. Report Example
5. Forecasts

Advanced topics:

• Payroll Automation with No-Code and Low-Code
• Payroll Testing
• Extended Functions
• Custom Actions
• Security

Embedded Payroll

As an API-first software, the Payroll Engine is designed to be integrated into service-oriented landscapes and HR platforms. An example of such integration is the web application that supports the core payroll processes.

Integration includes both functional and technical aspects

• Functional Integration with the model adaptation
• Technical Integration including the communication and interfaces

Licensing

The Payroll Engine uses the MIT License, which explicitly allows users to reuse the code for any purpose. All dependent third-party components are also licensed under MIT or Apache 2.0.
