From numbers that explain to numbers that steer.

I help mid-size B2B services companies build a finance function that looks forward: a handful of goals that actually matter, numbers you can build on, and dashboards that open the conversation instead of closing it.

Open a row to drill through to the underlying entries and the invoice itself.

A dashboard that puts result, budget and last year side by side, so you see at a glance what the conversation should be about. Financial figures sit next to operational data, so you can see whether a margin drop is about price or about utilisation. And from any row you drill through to the underlying entries, right down to the invoice.See more examples under services
My take

AI to build the tools, not to run your numbers.

  • Repeatable
  • Reliable
  • Auditable
  • Independent

I use AI to build what you need faster. What you get is ordinary Python scripts and Power BI models: auditable code that you can re-run as often as you like, at no cost. The result is output in Excel and Power BI that anyone can follow.

No AI agent in your monthly close, and therefore no hallucinations or inconsistency, no dependency, no privacy exposure and nothing you cannot verify.

The problem

The monthly close takes two weeks. The conversation about it takes twenty minutes.

In most growing services companies, most of the time goes into producing numbers and the least into doing something with them. The management meeting either has limited insight into the data, or starts with whether the figure is right rather than with what to do about it.

That is rarely a question of better people. It is a question of goals that were never sharpened, controls nobody set up, and reporting that is assembled by hand.

  • Numbers that disappoint at the end of the year?
  • Debate about which number is right, instead of about what it means?
  • Dashboards that look good but never put a target next to anything?

Portrait of Vincent Blaak
About

An accountant who hates manual work.

I’m Vincent Blaak, a Dutch chartered accountant. Nine years in audit, financial control, business control and ESG reporting, the last of them at a services company that grew from €70M to €150M. That is where I learned what good reporting is worth when it comes with sharp goals.

Working for myself, that is what I focus on: sharpening the goals, making the numbers reliable and taking the manual work out. Mostly remote, and where possible from a coast with decent waves.

What do you want to steer better?
