1. The EU-US Data Privacy Framework (DPF)
While the Schrems II ruling initially challenged US cloud providers, the current EU-US Data Privacy Framework provides a legal basis for data transfers. Compliance, however, is not automatic.
The issue
Under the US CLOUD Act, federal agencies can potentially demand access to data held by US providers — even when physically hosted on European servers.
The risk
Accounting and payroll records contain sensitive PII — employee names, salaries, bank details. Using US software for French statutory records requires verified DPF certification and robust contractual safeguards.
2. GDPR compliance for financial data
All data processed by a French subsidiary must adhere to GDPR, regardless of where the software provider is headquartered.
Data minimization
Systems must be configured to process only the minimum personal data necessary for the French entity's operations.
Data residency vs. sovereignty
Hosting data within the EEA is a necessary first step, but it does not solve the sovereignty issue if the parent company remains a US "Electronic Communication Service Provider."
Standard Contractual Clauses (SCCs)
Any transfer of PII to US headquarters for consolidation must be governed by the latest approved SCCs and a comprehensive Transfer Impact Assessment (TIA) documenting the risks of foreign government access.
3. Localization vs. sovereignty: a critical distinction
When selecting a global ERP, do not confuse these two concepts:
- Localization — the software's ability to handle French VAT and PCG reporting (the "accounting" problem).
- Sovereignty — the legal control and protection of the underlying data (the "legal" problem).
High-risk scenario: a multinational ERP may be perfectly localized for French tax forms while still presenting a massive GDPR sovereignty risk, if its data architecture allows unmonitored access by the US parent or US authorities.
4. Strategic recommendation
To mitigate exposure without sacrificing operational efficiency, we recommend a hybrid data architecture:
- Isolated local payroll — a dedicated, locally hosted French HR/Payroll system for the most sensitive employee PII.
- Aggregated consolidation — configure the US-based global system to receive aggregated financial figures, not transaction-level PII.
- Encrypted "bridge" — end-to-end encryption between the French compliance tool and the US headquarters, with keys held by the EU entity where possible.
