Challenge

A global tax consultancy relied on ETL pipelines to move client financial data into its tax reporting systems.

Data errors could lead to incorrect calculations, and manual checks were time-consuming and incomplete:

Risk of incorrect data in tax reports.
Manual, sample-based data checks.
Complex transformations across many sources.
Tight reporting deadlines.

The consultancy needed rigorous, repeatable data testing.

Solution

Winklix designed and executed a comprehensive ETL testing approach.

Data test strategy

We defined checks for completeness, accuracy, transformations and reconciliation.

Automated validation

Automated tests compare source and target data at scale.

Data quality rules

Business rules were codified to catch anomalies early.

Reporting

Clear test reports highlighted issues for fast resolution.
