Payroll Systems

Payroll systems represent the authoritative source of labour cost.

However, labour activity is often recorded earlier in field systems such as site diaries or timesheets.

The role of payroll integration is to ensure that the financial totals recorded in payroll remain aligned with operational labour records.

Payroll Data Sources

Payroll systems typically export structured data including:

• employee identifiers
• payroll period
• hours worked
• gross labour cost

These records are ingested into the platform using adapters.

Example systems include:

• PayCat
• MYOB Payroll
• ADP
• other payroll platforms

Integration Model

Payroll records are retrieved using the adapter layer.

Example workflow step:

FETCH → payroll.pay_records

The adapter retrieves payroll data and returns normalized records.

These records are stored inside the workflow pipeline context.

Canonical Payroll Record

Payroll records are normalized into a canonical structure.

Typical fields include:

employee
period
hours
gross_cost

These normalized records become PayrollRecord constructs.

Labour Reconciliation

Once payroll records are available, they can be reconciled against operational labour data.

Example workflow:

FETCH → labour_entries
FETCH → payroll_records
TRANSFORM → reconcile_hours

The reconciliation process compares:

• labour hours recorded in field systems
• payroll hours recorded by payroll

Differences are recorded as variance.

Handling Variance

Variance records typically include:

Worker
AssignarHours
PayrollHours
Variance

These records allow finance teams to identify discrepancies.

Examples include:

• missing timesheets
• incorrect project assignments
• payroll corrections

Operational Outcome

Payroll integration enables reliable labour reconciliation.

Organizations gain visibility into discrepancies between field activity and payroll totals.

This ensures labour costs remain aligned across operational and financial systems.
