Data basis for family offices: consistency beats perfection

Typical friction points

The same asset can show up differently across banks and reports—classification, valuation, FX basis, and benchmark choices often diverge. When the basis is inconsistent, performance, risk, and reporting become hard to compare and expensive to reconcile.

Three priorities

Start with a maintainable classification and security master. Then standardize valuation and FX basis with versioning and change history. Finally, treat data QA (missing values, anomalies, reconciliations) as a daily workflow—not a month-end fire drill.

How to implement

Maintain a clear basis register: classification, valuation, FX, benchmarks, periods, and fee handling. Define who can change what, approval gates, and auditability. Once stable, roll out analytics modules iteratively so capabilities scale without breaking governance.
