Compliance & Tax Advisory for Peppol and other mandates

A DACH-headquartered specialty logistics group operates subsidiaries across 16 European countries with heavy Central and Eastern European exposure. The group has active mandate obligations in Italy (SDI), Hungary (RTIR), Romania (e-Factura), and Belgium (Peppol, live since January 2026). Poland (KSeF) is arriving. The EU ViDA framework looms on the horizon.

The group controller tracks regulatory changes across all jurisdictions manually. Each subsidiary handles its own compliance in isolation. There is no consolidated view of mandate status, no shared process for responding to regulatory changes, and no systematic reconciliation between Peppol invoices and country-specific reporting channels.

A recent Iberian expansion added Spanish Veri*factu obligations to the portfolio. The internal team is running at capacity. Regulatory changes happen simultaneously across jurisdictions, and the team cannot keep pace.

For a profile like this, the most common risks a Compliance & Tax Advisory engagement would surface and address:

Simultaneous mandate changes

Regulatory changes happening across 5+ jurisdictions in the same quarter. Internal team cannot research, assess impact, and implement responses in parallel.

ViDA scope creep

Digital Reporting Requirements under ViDA evolving faster than internal governance can track. What starts as a 2030 concern becomes a 2027 preparation requirement.

Duplicate source of truth

Cross-system reconciliation between Peppol invoices and country-specific reporting (SDI, RTIR, e-Factura) creating conflicting records. No clear authoritative source per document type.

Penalty blind spots

Migration windows for schema updates (e.g. RTIR v4.0) expire without action because nobody in the group is monitoring the specific jurisdiction closely enough.

For this profile, we would establish continuous monitoring across all 16 jurisdictions. The group controller would receive a Monthly Compliance Brief covering new mandates, updates to existing regimes, watch-list items, and prioritised action items with named owners and deadlines.

When a mandate changes, we would deliver a structured impact assessment within two weeks. For the Hungarian RTIR v4.0 schema update, for example, the group would receive a detailed assessment of which subsidiary invoices are affected, what schema fields need mapping, and a 90-day migration plan.

We would also provide reconciliation guidance for the Peppol/SDI/RTIR overlap, establishing clear rules for which system is authoritative per document type and country, preventing the duplicate-source-of-truth problem before it creates audit findings.
