What we offer

Four ways to work
with us.

Interim tax leadership and transformation, ERP go-live support, a fractional Finance Director or step-up CFO, AI workshops for in-house teams, senior advice on tap — each model is designed for a different situation. Find the one that fits yours, or reach out and we'll tell you what we'd recommend.

01 — Interim

Interim Tax
Director

Available from September 2026 Tax Transformation ERP & Tax Technology Senior from day one

Senior tax leadership for the situations that can't wait — a hiring gap, an ERP go-live, a tax transformation, or a market entry that needs someone who can run the tax workstream from day one. We've implemented ERP systems (SAP S/4HANA, Oracle, Hyperion), built tax functions from scratch, and redesigned reporting workflows from manual to automated. Operational within days. No ramp-up. No junior support doing the actual work.

Engagements run up to 40 hours per week across 4–24 weeks — full-time or part-time, shaped around the mandate. We work on-site, remotely, or a combination.

What's included

  • Full tax position mapping from day one — open filings, pending audits, advisor relationships, internal capability
  • Tax technology — helping in-house teams get practical value from AI through prompt libraries, smarter workflows, and hands-on guidance built around real tax work
  • End-to-end project management — scoping, workstream coordination, deadline ownership, and delivery across complex multi-party tax projects
  • Corporate income tax oversight — provisioning, filing calendars, cross-border positions
  • Tax accounting and reporting — deferred tax, period-end close, group financial statements, and audit support under IFRS, US GAAP, and Dutch GAAP
  • ERP implementation & tax technology — SAP S/4HANA (configuration & testing), Oracle ERP, Hyperion consolidation, ONESOURCE Tax Provision, Blackline
  • Tax transformation — building tax functions from scratch, redesigning manual reporting to automated workflows, standardising data and eliminating inefficiencies
  • Tax process redesign — reducing external advisor touchpoints, standardising data flows, and building repeatable frameworks that scale
  • CFO, General Counsel, and VP Finance-level reporting and stakeholder alignment
  • Handover documentation and transition to permanent hire or next structure

Operational within days, not weeks. The expectation is immediate contribution — and that's what we deliver.

02 — AI Implementation

AI for
Tax Teams

AI Implementation · Now available Practical · Not theoretical

Most tax teams have AI licenses by now. Far fewer get real value from them — because the gap was never the tools. It's knowing how to apply them to actual tax work, and having the time to learn while the ongoing work keeps coming. That's the gap we close: we've implemented AI inside in-house tax functions ourselves, within the data and confidentiality constraints that come with them.

Two ways to work with us. A team workshop — half-day or full-day, on-site or remote, built around your team's real workload, leaving them with working prompts the same day. Or an implementation sprint — 4–8 weeks, part-time, where we pick two or three workflows, build the prompt library and tooling around them, and train your team to own it.

The two formats

Team Workshop · Half-day or full-day

Hands-on, built around your team's actual workload — not generic demos. Prompt fundamentals for tax work, live builds on real questions from your desk, and a shortlist of use cases worth pursuing. Your team leaves with working prompts the same day. On-site or remote.

Implementation Sprint · 4–8 weeks

We select two or three workflows with the highest return — research and memo drafting, document review, compliance preparation — build the prompt library and tooling around them, and train your team as we go. It ends with tools in daily use that your team owns and keeps improving without us.

  • Works with the tools you already have — ChatGPT, Claude, Gemini, Microsoft Copilot, NotebookLM, and specialist tax platforms
  • Designed around your data and confidentiality constraints — we've worked within enterprise restrictions ourselves

A clear boundary

AI accelerates research, drafting, and routine analysis. It doesn't replace professional judgment on novel or high-stakes positions — and we'll always be clear about where that line is.

03 — Fractional

Fractional Finance
Director

Available from September 2026 Fractional CFO Retainer-based

Senior finance and tax leadership in the room, without the full-time headcount. A Finance Director today — a step-up CFO as you grow. We integrate with your team on a retainer, covering tax strategy, financial oversight, and the intersection of the two — staying ahead of issues before they become problems.

Typically 8–16 hours per month, structured around your rhythm — whether that's a weekly check-in, a monthly deep-dive, or something in between. More or fewer hours where the situation calls for it. The model adapts to what you actually need.

Discuss a retainer →

What's included

  • Senior finance and tax oversight in one engagement — no gap between the two disciplines
  • Management reporting and board pack review — numbers your leadership team can actually make decisions from
  • FP&A, budgeting, and forecasting — structured around the company's stage and what the CFO or CEO genuinely needs
  • Tax risk monitoring embedded in finance — issues flagged at the right moment, not after the fact
  • Financial controls and compliance oversight — proper structures, not reactive fixes
  • Treasury and cash management input — visibility and discipline across the balance sheet
  • Banking, audit, and investor relationship management where needed
  • Finance function assessment and improvement — from under-resourced and reactive to structured and reliable

Typical clients: Series B to pre-IPO scale-ups and mid-size companies that need senior finance and tax leadership embedded in how the business runs — not called in when something goes wrong.

04 — On-demand

Tax & Finance
on Tap

Subscription Reactive On-demand

A senior tax and finance person you can actually reach — who gives you a straight answer quickly, without a junior in the middle and without a Big 4 invoice at the end of it. For finance managers and CFOs who need a reliable senior voice on the other end for questions, reviews, quick calls, and brief check-ins.

Questions by email or call. Responses within 24 hours. A monthly subscription that covers the full range of tax and finance topics — whatever comes up, not just what fits a narrow brief. When something grows into a project, we'll tell you before it becomes a surprise.
