Compliance & Tax Advisory
Standing regulatory monitoring across every e-invoicing mandate that applies to your group. Monthly compliance brief, mandate change response, and cross-system reconciliation guidance.
Who this is for
- Group controllers and CFOs at mid-market organisations operating across multiple mandate jurisdictions.
- Multi-country groups with exposure to 5+ concurrent e-invoicing regimes (Peppol, SDI, RTIR, e-Factura, KSeF, ViDA).
- Finance leadership that cannot keep pace with simultaneous regulatory changes across subsidiaries.
- Tax and compliance teams that need a standing partner for continuous monitoring, not a one-off assessment.
Who it isn't for
- Single-country businesses with exposure to one mandate only. The cost structure assumes multi-jurisdiction scope.
- Companies looking for implementation delivery. This is advisory and monitoring, not hands-on-keyboard work (see Implementation).
- Teams that only need a one-time regulatory review. Consider a Readiness Assessment instead.

Monthly Compliance Brief
Structured memo covering new mandates, regulatory updates, watch-list items, and prioritised action items for your team. Delivered to your inbox on the first business day of each month.
Mandate monitoring across jurisdictions
Continuous tracking of regulatory changes across all jurisdictions in your scope. We flag what matters to your group and filter out the noise.

Cross-system reconciliation guidance
Advisory on reconciling Peppol invoices against country-specific reporting systems (SDI, RTIR, e-Factura). Preventing duplicate-source-of-truth problems across channels.
Quarterly compliance review call
60-minute structured review with your compliance lead. Walk through open items, upcoming deadlines, and strategic positioning for mandates on the horizon.
Anonymised customer profile. Names and figures changed. Company details available on request under NDA.
DACH-headquartered specialty logistics group
The situation
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.
What commonly goes sideways
For a profile like this, the most common risks a Compliance & Tax Advisory engagement would surface and address:
Regulatory changes happening across 5+ jurisdictions in the same quarter. Internal team cannot research, assess impact, and implement responses in parallel.
Digital Reporting Requirements under ViDA evolving faster than internal governance can track. What starts as a 2030 concern becomes a 2027 preparation requirement.
Cross-system reconciliation between Peppol invoices and country-specific reporting (SDI, RTIR, e-Factura) creating conflicting records. No clear authoritative source per document type.
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.
What a Compliance & Tax Advisory engagement would deliver
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.
penalty exposure across mandates
Proactive monitoring and timely response eliminates the window where non-compliance penalties accumulate unnoticed across subsidiaries.
