Mert Ilter - Senior Interim Finance Professional, Hamburg

20+ years building, leading, and fixing finance functions across Germany, the UK, Canada, and Central Asia — for new GmbHs, EMEA subsidiaries of listed groups, and growth-stage companies.

Interim Financial Controller - Mert Ilter
I have worked across energy infrastructure, technology, retail, logistics, and food production — in organisations ranging from newly founded GmbHs with no finance team at all to EMEA subsidiaries of publicly listed international groups. The breadth is deliberate. It means I walk into an engagement already knowing the problems you haven't told me about yet.

What distinguishes my profile from a typical interim hire is the combination of operational precision and executive-level perspective. I can run your month-end close on a Tuesday and present your board reporting on a Thursday. I have never been a consultant who analyses from a distance — I sit inside the finance function, work the numbers, own the deadlines, and take accountability for the output.

What I Have Actually Done

Built finance functions from scratch

Designed chart of accounts, selected and implemented ERP systems, established controls and produced first structured reporting packages for companies that previously had no finance function. 

Stepped into teams under pressure

Handled sudden controller departures, reporting backlogs, close delays, audit pressure and stakeholder uncertainty during finance leadership gaps. 

Connected German entities with international parents

Supported communication across HGB/IFRS, local German finance expectations and international group reporting requirements in multiple languages. 

 Your Finance Function Cannot Afford to Stand Still.

Why One Person Matters

Working as a single senior practitioner is not a limitation — it is a deliberate choice about quality, accountability, and direct communication.

When you work with me, the person who understands your situation in the first call is the same person who shows up, takes ownership, and delivers the handover. There is no layer in between. No junior delegation. No "let me check with my partner." No staffing reshuffle in month three.

In finance, that matters. Trust, continuity, and accountability are not optional.
Talk to Me About Your Situation

A 30-minute conversation is enough to tell you whether I am the right fit — and if I'm not, I will say so directly.
