For bookkeepers, controllers and accountants

„I am not allowed to use AI at work.”

We automate your admin. The AI sees the numbers, the names stay with you.

How we work
  1. We pick one process.

    The process that eats the most of your hours today.

  2. We automate it.

    It runs alongside your current way of working, until it is right.

  3. You win hours back.

    After that, we pick the next process.

Proces voor proces. Elke stap levert direct iets op.

Your data · our starting point

Your data stays yours.

Most AI stories start with what could happen. We start with what does not: before anything reaches a language model, we strip out everything that points to a person.

Unrecognisable

Names, case and client numbers are replaced with references before data reaches the AI. What the model sees is not your client.

Location

Processing within the EU. No exceptions.

Control

Every step logged, every outcome traceable to its source. A human approves.

How we arrange it per solution

Recognition

Do you recognise this work?

Work that returns every week or month, that costs too much time on the same exceptions. In the words of your own team. Click a task for the full description.

How it works

Three steps. You can stop after any step.

Each step has a concrete result. You can stop after any step.

Step 01

Discovery call

Thirty minutes, free, no slides. Three questions: which work returns every period, who does it, and where the biggest irritation sits.

Delivers One named process + first estimate in person-days
Step 02

Scope on one page

Before anything is built, one page lays out which process it is, which data goes in, what the solution does, and where the human decides.

Delivers Signed one-pager · scope · fixed price
Step 03

Build at a fixed price

Price up front, delivery date up front, test protocol per step at handover. No cost-plus billing afterwards.

What it costs

Fixed price, no surprises

What it costs depends on the process. What is fixed is how we agree it.

01
Fixed price, set up front.

You know what you sign before you sign. Price and delivery date sit on the same one-pager.

02
Fixed delivery date, on the one-pager.

The date sits on the same page as the price. Extra work runs through a new, separately scoped block, with its own price and date.

03
Test protocol at handover.

Tested against a closed period whose outcome you already know. Any differences we lay out side by side, before you sign off.

Our promise

If we do not believe it pays back within a year, we say so. And we do not build it.

Behind Proofin

Two people

No account manager between you and the build. The same person who sits at the first call also builds the solution.

First call · marketing

Jan van Dam

Runs the discovery calls and keeps an eye on whether you should not start on something you do not need. If a process is not a good candidate to build, he says so before a one-pager gets involved.

Start with a discovery call.

Thirty minutes, no cost. You tell us which work returns every period. We say whether this is something to take on, or not.
