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.

Good fit

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.
Not a fit

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.

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:

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.

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.

Indicative outcomes
Near-zero

penalty exposure across mandates

Proactive monitoring and timely response eliminates the window where non-compliance penalties accumulate unnoticed across subsidiaries.

<2 weeks

average response on mandate changes

From regulatory publication to a structured impact assessment with recommended actions in your inbox.

~1 day/week

reclaimed by the group controller

Regulatory monitoring, research, and cross-jurisdiction tracking handled externally. Controller focuses on decisions, not data gathering.

FAQ

Frequently asked questions

How quickly do you respond when a mandate changes?
Under two weeks from publication to a structured impact assessment in your inbox. Critical changes (e.g. schema breaking changes with short migration windows) get flagged within 48 hours via email with a preliminary assessment.
Do you cover mandates outside the EU?
Yes. We cover Peppol-adopting jurisdictions globally (Singapore, Australia, New Zealand, Japan) and major non-Peppol e-invoicing regimes where your group has exposure. Scope is defined during onboarding.
Can this replace our internal regulatory monitoring?
For most mid-market groups, yes. The engagement is designed to eliminate the need for your team to track regulatory changes across jurisdictions. You still own the decisions, but we handle the monitoring and analysis.
What is the difference between this and the Readiness Assessment?
The Readiness Assessment is a one-time diagnostic. Compliance & Tax Advisory is a standing engagement that keeps you current as mandates evolve. Many clients start with an assessment and follow with a retainer.
How do you handle overlapping mandates (e.g. Peppol + SDI)?
We map the intersection explicitly. For Italian subsidiaries, for example, SDI remains the domestic obligation while Peppol applies for cross-border. The brief flags where obligations overlap and where they conflict, with clear guidance on which system is authoritative for each document type.
What happens if we add new countries mid-engagement?
We add them to the monitoring scope within the next monthly cycle. Pricing adjusts at the next quarterly review. No break in coverage.
