EXTG ENGINEERING

Look inside
the work.

Recruiting systems, employment workflows and payroll calculations. Here is how we approach the software behind our delivery.

PAYROLL TECHNOLOGY

Author the rules.
Run a specific version.

Studio and the calculation runtime have separate jobs. The platform manages people and payroll work; Studio manages the rules used for calculation.

Payroll Studio

Define components, calculation steps and test cases.

Rule package

Save a fixed rule version with its inputs and declared scope.

Payroll Runtime

Execute compatible rules and return results with a calculation trace.

ExtG Workforce

Manage entities, groups and payroll operations. New engine workflows are verified through internal shadow calculations.

Integration scope

The diagram explains responsibilities. It does not imply that every live payroll uses the new engine, or that all rule packages are certified for production.

01

Make the calculation inspectable.

Use explicit inputs, decimal arithmetic and defined rounding rules. Keep the rule and runtime version with the result so that a calculation can be examined and reproduced.

02

Keep authority with the right team.

Portal roles and workflow stages determine who can see information and perform an action. Candidate delivery, payroll review and employment changes have different responsibilities.

03

Separate a test from a release.

A matching test result is evidence about that case. Production use also depends on the rule’s scope, review, deployment and the operating workflow.
