01 · Your Firm in Numbers

The work is there.
Just nobody to do it.

Your bottleneck is not the mandate, it is capacity. And a substantial part of that capacity goes to work nobody pays you a fee for:

30–40 %
of your processing time goes to receipt chaos, chasing and queries, not to the actual professional work
Field experience from the practice environment
▤

Receipts arrive chaotic and late

The shoebox, the photo on WhatsApp, the bulk PDF in no order. Before anything can be booked, it first gets sorted, deciphered and completed.

☎

Queries devour your productive hours

"What is this receipt?", "Where is the March bank statement?", "When will my report be ready?" Every question individually, by email and phone, in the middle of processing.

⏱

Deadlines press all year round

VAT returns, payroll runs, annual accounts, extensions, follow-ups. One overlooked date costs you money and trust.

◔

New talent is missing, the work remains

Positions stay open for months, experienced staff retire. The extra work lands on those still there, and on your evenings.

02 · The Solution

An employee for the groundwork.
Not for the advice.

Your AI employee moves into your firm on his own computer and takes over first what every business generates, then what only a firm generates. Tax advice, professional review, approval and signature remain with the licensed professional without exception. He prepares, you decide.

The foundation · from day one
Answering & pre-sorting emails Recording & triaging client inquiries Drafting proposals & fee agreements Writing & chasing invoices Coordinating appointments & follow-ups Requesting documents & reminding Maintaining filing, scanning & archiving Maintaining firm website & job postings
And specifically for your firm

Receipts, pre-entry & chasing

He takes whatever your client sends: photo, PDF, shoebox scan. He turns it into a clean, sorted stack for bookkeeping.

  • Sorting, naming receipts & assigning periods
  • Spotting missing documents & requesting them from clients
  • Preparing groundwork for DATEV, Addison & Agenda
Wall calendar with marked filing dates next to a screen with a deadline list and follow-ups

Deadline & follow-up watchdog

He keeps the list nobody else keeps: who promised what and when, what is due, where this week gets tight.

  • Keeping deadlines & follow-ups in view
  • Reminding clients in time, and more than once
  • A morning priority list for your team
Advisory meeting at the conference table: a printed financial report open between coffee cups, a pen pointing at a row of numbers

Client communication & reports

He answers the same recurring questions and explains numbers in plain language, as a draft you approve before it is sent.

  • Answering standard client questions
  • Explaining reports & analyses in plain terms
  • Guiding new client onboarding step by step
03 · What He Works With

He runs your software.
Not the other way around.

Your AI employee sits at a real computer in your firm: with mouse, keyboard and screen. He works in the same software as your team. You change nothing, you export nothing, you learn nothing new.

04 · A Working Day

A Tuesday
with a hundred hands.

06:30

The receipt stack is already sorted

Overnight he named the incoming receipts, assigned periods, weeded out duplicates and noted which bank statements are missing.

08:45

The deadline list is on the table

"Seven mandates still incomplete for the VAT return, four of them reminded yesterday." You see the status before the first phone rings.

10:20

You send a voice message

"Ask Kern bakery for the February and March cash reports and send him the list of what is still missing." That is all he needs.

13:15

Standard questions are already answered

Four client emails on mileage logs, entertainment receipts and extensions sit ready as drafts. You skim, approve, done.

16:40

The report in plain language

For Mr. Röder's report he has drafted a clear explanation, with the three points he would raise. You review and sign off.

22:00

You leave. He stays.

He prepares tomorrow's groundwork, sets up the onboarding package for the new mandate and writes you where this week gets tight.

05 · How He Joins Your Firm

Not an IT project.
A move-in.

01
Application

You fill out the form: five minutes, no phone call, no meeting. We read it and decide whether your firm is a fit.

Online · 5 minutes
02
24-hour test

If it is a fit, you receive an access link. Your AI employee reports in on your WhatsApp and spends 24 hours working real tasks from your firm, with test data if you prefer.

Free · no obligation
03
He moves in. We stand behind it.

Then we build him around your firm: your client structure, your templates, your tone. Monitored by our audit agent. Everything outward-facing is approved by you first.

From then on: 24/7
06 · The Difference

He does not start from zero.

A new hire at the firm needs months to learn how things are done, making every rookie mistake once along the way. Your AI employee arrives with those apprentice years already behind him.

He starts with the collected experience of every deployment we have ever run.
01
Experience from minute one

Thousands of documented procedures, dead ends and solutions from years of real work are his starting point, not his learning goal. What went wrong once somewhere else simply does not go wrong at your company.

02
He gets better without you doing anything

Whatever one agent solves anywhere, we review and pass on to all. Next month your employee can do things he cannot do today. No training, no surcharge.

03
Always the latest AI generation

The major AI models get stronger every month. Your employee automatically switches to the best one available. Same colleague, same knowledge, always the sharpest available mind. You never deal with the technology.

07 · Fair Questions

What firm owners ask first.

And he does not. He is groundwork: he sorts receipts, follows up, watches deadlines, drafts replies and prepares analyses in plain language. Tax advice, professional review, approval and signature remain with the licensed professional without exception. Nothing goes out without your approval, and that is not a promise, it is how it is built.

On a computer that physically sits in your firm, not in someone else's cloud and not with a provider abroad. The documents never leave the building. You can literally watch him work. For a profession bound to confidentiality, that is exactly the difference from cloud tools and subscription services.

No. He fills the position you cannot staff anyway. Your professionals stop sorting receipts and chasing clients by phone, and go back to doing what they were trained for. If you have to turn down mandates today, this is how you win capacity back.

You do not have to. You text him on WhatsApp or send a voice message, like any employee. There is no interface, no training, no migration. Your DATEV environment, your filing and your workflows stay exactly as they are.

Less than a part-time hire. The exact number depends on what he is meant to take over for you. You state that in the application and receive your offer in writing, together with access to the 24-hour test. The first of these AI employees has worked daily in real business operations for over a year and a half, this very page was built by one. In the test you experience it yourself: on your own WhatsApp, with your real tasks.

08 · The Next Step

Start taking on mandates again.

No phone call, no meeting, no sales pitch. You fill out the application form in five minutes. If it is a fit, you receive an access link, and your AI employee reports for duty on your WhatsApp for 24 hours.
