Big 4 rigor.
Mexican ground truth.

I help Mexican companies and international groups — from the US, Canada, Europe and Latin America — build finance functions that stand up to scrutiny, grounded in nearly two decades of operating businesses in Mexico, not just advising on them.

Services

From a clear map to decisions you can trust.

Whether you’re a Mexican company preparing for growth or an international group that needs a clear view of what happens in Mexico, the goal is the same: reliable numbers, clear accountability and fewer surprises. Every engagement starts with an evaluation: either a fixed-fee map of how finance actually works in your Mexican operation, or a shorter readiness check if processes are already documented. What comes next depends on what it reveals. Fixed fees where the scope is clear, day-based pricing where it isn’t. The price is confirmed in writing the business day after our first call.

Who it’s for

Groups with a subsidiary, office or plant in Mexico whose numbers head office cannot fully explain. For a foreign group’s Mexican operation, the map takes about two weeks. Mexican companies that want to know where their finance function stands before investing in it, taking on a partner or bringing in outside money.

How it’s priced

A fixed fee, set by the size and shape of the operation and stated in the engagement letter. More depth in one area is agreed in advance.

What you get

  • Interviews and a look at the documents on the ground, with the people who do the work
  • Each part of the finance function assessed against a four-level maturity scale
  • The gaps that matter most, ranked
  • A plan to the next level, split between what your team can do and what needs outside help
  • A written report and a presentation to management or head office

Who it’s for

Companies whose map shows gaps, or that are starting in Mexico from scratch. Foreign subsidiaries that need to meet the group’s standard under Mexican rules; Mexican companies that have outgrown a finance function run on memory and goodwill.

How it’s priced

In days, estimated in the engagement letter from the map’s findings. Starting from scratch: a fixed price set by the level of activity.

What you get

  • Approval rules and authority limits, written down and in use
  • Procedures for sales and collections, purchasing and payments, payroll, inventory management and cost control
  • Reconciliations and a month-end close process that stands up to review
  • Internal controls, with evidence that they ran
  • Management reporting set up
  • For importers and IMMEX companies: landed cost, inventory and import values tied to the books
  • Handover to your team or a local hire

Who it’s for

Head offices that need a local check on their Mexican entity, and owners or boards who want to know each month that documented processes are actually being followed. It needs documented processes to test against; where they aren’t in place yet, build or fix comes first.

How it’s priced

A fixed monthly fee by tier, set by the size of the operation. Work outside the tier is quoted separately.

What you get

  • Monthly tests, by sample, that the documented processes ran: who performed, who reviewed, who reconciled, and where the figures came from
  • A monthly written report, with the exceptions found and their follow-up
  • Done by someone independent of the people who prepare the numbers
  • A clear limit, stated in every report: it is not an audit, and it doesn’t judge whether the processes are the right ones

Who it’s for

Companies with a sound base that need CFO-level judgement without a full-time CFO: Mexican SMEs, and foreign subsidiaries whose local manager and head office need one financial voice in Mexico. If the base isn’t there yet, we start with a map.

How it’s priced

A monthly fee based on the days needed, agreed up front.

What you get

  • A monthly finance pack: results, cash, forecast and key risks
  • Cash forecasting, budget and monthly variance
  • Margin by product, contract or unit, and the KPIs that drive decisions
  • Treasury management, FX exposure, banking relationships and financing
  • Reporting for owners, boards, investors and head office, under IFRS or US GAAP
  • Coordination with your contador, tax advisers and auditors

Who it’s for

Funds, family offices and strategic buyers looking at a target in Mexico. Mexican owners preparing a company for sale or outside investment.

How it’s priced

A fixed fee built from the days the deal needs, with the scope written into the engagement letter. Big 4 due diligence methodology, adapted to the realities of operating in Mexico.

What you get

  • Quality of earnings, balance sheet and working capital analysis
  • Financial risks and contingent items, flagged for your tax and legal advisers
  • IFRS and US GAAP reading of Mexican statements
  • Assessment of internal controls and reporting quality
  • Support through negotiation and closing
Why work with me

Two worlds. One advisor.

Operator, not just advisor

I have directed construction, mining, retail, and import operations in Mexico for nearly two decades. I know what a financial decision looks like from inside a business, not only from a spreadsheet.

Between head office and the ground

Swedish, Finnish, English and Spanish, and based in Mexico since 2007. I sit between a head office abroad — in the Nordics, elsewhere in Europe, the US, Canada or Latin America — and the team here, and explain each to the other. For Nordic groups, in their own language.

Senior expertise, clear scope

KHT-qualified, with Big 4 experience at Ernst & Young across Finland, the United States, the United Kingdom and France. Fractional, project-based or ongoing support, always with a clearly defined scope, deliverables and fees agreed before work begins.

About

An unusual path — and that is the point

My career took a route most advisors did not take, and that route is the reason I can help you in ways most of them cannot.

I started at Arthur Andersen and Ernst & Young in Helsinki, where I spent nearly seven years auditing banks, technology companies, manufacturers, and multinationals. I worked on SOX 404 compliance for SEC-registered Silicon Valley technology companies. I helped one of the world’s three largest paper manufacturers build internal controls across four continents, working from offices in Finland, the UK, France, and the United States. I earned my KHT qualification — Finland’s equivalent of a Certified Public Accountant — and built a foundation in IFRS, US GAAP, and Big 4 audit methodology that has stayed with me ever since.

Then I moved to Mexico.

What followed was nearly two decades of learning that financial training and business reality are two very different things — especially in a market as complex and dynamic as Mexico. I have directed construction operations across residential and commercial projects. I have managed mining, retail, and import operations. I have navigated SAT compliance, Mexican banking and regulatory requirements, personnel across multiple companies, and kept a private holding group’s finances in order through economic cycles and currency moves.

That combination — European financial rigor and real Mexican operational experience — is what I bring to every engagement. I have sat on both sides of the table my clients are navigating.

I now divide my time between advisory work and residual interests in my own Mexico-based companies. I am available for fractional, project-based, and retainer engagements, structured around what you actually need.

Outside work, family comes first. Beyond that it’s golf, sailing, and football — preferably in good company. Mexico became home a long time ago, and I wouldn’t change that for anything.
