Services

Lead a finance function, or strengthen the team around your finance lead

Four ways to work together. On an interim basis I can own a function myself, below CFO level, or support your CFO, Finance Director or Head of FP&A. Everything here builds on work I have done in the role.

01

Interim country finance manager or head of controlling

When the seat is empty, I step in and run the function: the finance of a country or branch entity, or the controlling team, reporting to your CFO or group finance. I can also cover an FP&A or controlling role during a vacancy, absence, restructuring or busy period. I own the budget, reforecast and expense planning, control actuals against them every month, handle month-end and accruals, and report to group finance, the CFO and the Board.

Built on running the full budget and reforecast cycle for a German country entity and supervising accounts payable and treasury for the Benelux.

02

Budgeting & forecasting cycles

I run or support your annual budget, reforecast or multi-year plan, including in Oracle planning, from preparation and challenging cost-centre inputs through to Board-level reporting.

03

Business partnering & fractional support

A senior finance partner for your Finance Director or CFO, part-time or a set number of days a week: budget conversations with cost-centre heads, preparation for strategic initiatives and presentations, and day-to-day support.

04

Finance change projects

Hands-on delivery when finance is changing: restructurings and expense ratio programmes, process redesign, ERP changes such as the move from Sun to Oracle and the ARCS rollout, cleanups, multi-entity reporting, and legal entity transfers like the post-Brexit move to a new Luxembourg carrier.

Engagements can be interim (full- or part-time), fractional, or project-based, and run remotely from Lisbon with on-site visits when needed. Terms are discussed per engagement. Interested in AI agents for finance processes? See AI agents for finance.

Who I help

Companies that need an interim finance lead, or someone ready to step up

I am that interim finance lead: I step in and own the FP&A and controlling cycle. And for companies looking for a head of controlling or finance director, I am the person ready to step up into that role. I have run the full budget, reforecast and controlling cycle for a country entity, working directly alongside a Finance Director.

My own background is the insurance industry: twelve years, most recently preparing the full budget and reforecast expense planning for Germany and Switzerland and controlling actual expenses against it. Along the way I supported the organisational restructuring of the German business, ran the future FTE planning, supported and executed the Group-wide expense ratio reduction programme, worked directly alongside the Finance Director, planned the set-up budget for a new Swiss legal entity, and redesigned the budget and reforecast submission processes for Europe. Insurers and financial services firms get someone who knows their numbers from the inside.

Who

  • Companies hiring an interim FP&A or controlling lead
  • Companies looking for a head of controlling or finance director who is ready to step up
  • CFOs, Finance Directors and group finance teams who need hands-on support
  • Country and branch finance managers in groups

Companies

  • Any sector
  • Insurers and financial services: twelve years of insurance experience
  • Mid-market companies
  • International groups and their country or branch entities
  • Multi-entity and multi-currency set-ups

Region

  • All of Europe as my home base
  • Worldwide, for remote teams anywhere
  • Four working languages: Dutch and English (native), German (B2/C1) and Portuguese (C1)

Typical situations

  • The budget or reforecast cycle drags on Weeks of spreadsheet chasing and back-and-forth with cost-centre heads.
  • Pressure on expenses and cost ratios You need someone who can plan costs and challenge cost-centre heads constructively.
  • A finance seat is empty A country finance manager, head of controlling or FP&A role is uncovered during a vacancy, absence, restructuring or transformation, and someone needs to own it.
  • Manual, slow processes Reconciliations, submissions and reporting packs that take too long and could be streamlined.
  • Restructurings I reorganise cost centres, move FTEs and expenses to the new structure and track redundancies and savings, as I did in the restructuring of the German business.
Track record

Twelve years in insurance finance at Hiscox, covering the full finance cycle, from payables, treasury and accounting to FP&A, budgeting and controlling for a country entity. Before that, consulting projects at SOLVE Consulting and a transaction-advisory internship at Ernst & Young. The skills below carry over to finance teams in any sector.

  • Future FTE planningResponsible for FTE planning: I led the conversations with managers on which new FTEs were needed, which would be cut and which would move to other parts of the organisation.

I gathered feedback from all the European finance managers and redesigned the process based on that.
  • Reinsurance calculationsManaged Quota Share reinsurance calculations and submissions (insurance-specific).
  • Brexit – New Luxembourg Insurance CarrierAfter Brexit, the old European entity was merged into a new insurance carrier in Luxembourg. For the Benelux, I handled the preparation: moving bank accounts, gathering documentation for banks, the Chamber of Commerce, central banks and auditors, getting everything ready for the transfer bookings between the two entities. I also sat in the working groups and maintained regular communication with regulatory bodies.
  • Benelux tax declarationsPrepared the yearly tax declarations for the Benelux, by country:

Case studies in the insurance industry

Three pieces of work from my finance roles in the insurance industry. The descriptions come from my CV and the figures from my time in those roles.

Europe · Change project

Leading the ARCS reconciliation rollout

Accountant Benelux, Lisbon

As part of the company-wide Finance Transformation Programme and the move from Sun to Oracle, I led the implementation of Oracle ARCS automated reconciliations for the European businesses: the Netherlands, Belgium, France, Germany, Spain and Portugal, and later Ireland. On the premium bank account, which handled thousands of transactions a month, ARCS matched our cash flow bookings against the bank statements using automatic rules. The majority of transactions were allocated automatically, leading to significant efficiency improvements and cost reduction.

Seven countries all using the same automatic reconciliation process.

Germany · 2022–2026

German business restructuring

Financial Planning & Controller, Munich

Supported the organisational restructuring of the German business, as sales moved from six regional offices to a North, Mid and South structure. The marketing, propositions and technical underwriting departments were also restructured. I reorganised the cost centres, moved FTEs and expenses to the new structure, and tracked redundancies and savings with the management team.

Cost centres, FTEs and expenses moved to the new structure, with redundancies and savings tracked with the management team.

Group · 2022–2026

Group expense ratio reduction

Financial Planning & Controller, Munich

Supported and executed the Group-wide expense ratio reduction programme for the German business, which aimed to cut pure expenses as a share of gross written premium by one percentage point a year.

It delivered roughly 0.7 to 0.8 percentage points per year when premium growth missed plan.

Approach

How I work

I run the finance cycle end to end. For a German country entity I prepared the entire budget and reforecast expense planning and controlled actual expenses against it, working directly with cost-centre heads on their current and future plans.

  1. Into your cycle in week one

    I learn your budget, reforecast and reporting timetable: who owns what, the systems and the open issues.

  2. I run the cycle

    I prepare budget and reforecast expense planning end to end and control actuals against them every month.

  3. Variances with a reason

    Every gap against budget comes with an explanation, agreed with the cost-centre head who owns it.

  4. Reporting leadership can use

    I turn the numbers into Board-level reporting and presentations for the Finance Director.

  5. Agentic AI Finance

    Simpler processes, carefully automated

    [coming soon]

    I streamline submissions and reconciliations as I did with the budget and reforecast submission process, and the ARCS reconciliation rollout across seven European countries. I'm learning agentic AI for finance now, starting small with pilots where I approve every output.

Growing practice

AI agents for finance processes [coming soon]

AI agentic finance for finance teams is in progress and coming soon: AI agents that support FP&A, budgeting, forecasting and controlling workflows, with people approving every output.

Alongside my finance work, I am working with AI agents to improve financial processes within companies, such as reporting, reconciliations and variance commentary. It is a growing practice, and I am open about where it stands.
