AI for audit firms: more time for judgement, less chasing documents. We work out with you where AI takes work off your audit team, train your staff and put it into practice, connected to Caseware, DATEV and your other software.

Request lists, balance confirmations, sample testing, follow-up questions to the client: routine takes up a lot of time in every audit. AI Værk works with you from the first call to a solution in daily use. Client data stays under your control, on a server in your firm if you prefer.

Where AI saves your audit team time

Process balance confirmations

The software reads the replies that come back by post and email, compares each confirmed balance with the client’s balance list and enters the result in the working paper. Your team sees differences at a glance.

Keep the request list up to date

The software matches files in the data room to the right line on your request list. Whatever is still missing goes into a reminder to the client, which your team sends.

Prepare sample testing

For each item in the sample, the software finds the invoice and delivery note and enters date, amount and service period in the working paper. Your team judges whether the item holds up.

Illustrative use case

From 60 balance confirmations to a finished working paper

  1. 01

    The replies come in

    To audit receivables, you have written to 60 of the client’s customers. The replies arrive as letters, PDFs and emails over three weeks.

  2. 02

    The software compares

    On your firm’s server, it reads each confirmed balance, compares it with the client’s balance list and reports three differences and seven missing replies.

  3. 03

    Your team decides

    The results are in the working paper, and the second request to the customers who have not replied is ready. Your team resolves the differences and decides on further audit procedures.

Client data stays where you decide.

As a German public auditor you are bound to secrecy under § 43 WPO, the Public Accountant Act. So you decide where the software runs, and we set it up exactly that way.

  • Confidentiality in the contract: we and everyone working with us commit in text form to professional secrecy, as required by § 50a WPO and Section 203 of the German Criminal Code (StGB).
  • A data processing agreement under the GDPR, signed before the software sees real data.
  • Your data is never used to train AI models.
  • Every access is logged. You see who opened what, and when.

Working safely with AI: training for your audit team

Your team practises on post as it arrives during an audit: what does the software file, what does the AI see of it, and which question belongs with the engagement partner? Use the switch to see how client data stays protected.

Email from a client’s accounts team
What the AI sees:

“Dear Mr Krause, attached is the receivables balance list as at 31 December. The confirmation from Company 207Nordbau GmbH is €4,200 lower because the credit note only came in January. One more question: do we need a provision for the lawsuit? Kind regards, Person 6150Sabine Wolff”

  1. Your server inserts placeholders
  2. Sent encrypted
  3. Cloud AI processes it
  4. Your server puts the names back

Only your server knows which placeholder belongs to which person.

  1. Message arrives
  2. The AI on your server works with the full message

Nothing leaves your firm.

  1. File the list

    Match the balance list to the right client and audit area, even when the AI only sees the names as placeholders.

  2. Make the explanation testable

    Add the January credit note as an open item, so your team checks it against the document.

  3. Pass the technical question to the partner

    Recognise the question about the provision and put it to the engagement partner. She discusses it with the client.

Questions before getting started

Can we use AI with client data?

Yes. § 50a WPO allows you to bring in service providers, provided they commit to secrecy in text form. That is exactly what we set out in the contract, together with the data processing agreement. If the software runs on a server in your firm, the data stays on your premises from start to finish.

Does it work with Caseware or DATEV?

Yes. Where your audit software offers an interface or an import route, we pass results straight to your working papers, for example in DATEV Abschlussprüfung comfort. Otherwise your team moves them across from a work list. We check which route suits your firm in the AI audit.

Who decides whether the evidence is sufficient?

Your audit team. The software collects, matches and enters. Whether the evidence is sufficient and which procedure follows is your call.

What does getting started cost?

The initial call is free. If the task is already clear, we move straight to a proposal. If a closer assessment is needed, the AI audit costs €500, fully credited towards implementation with AI Værk. Small solutions start at around €2,000. If we find no useful AI application, the audit fee is waived; previously agreed expenses remain payable. Our proposal lists setup, licences, hosting and support separately.

Who supports implementation?

You work directly with us, the founders. Justus handles consulting, design and training; Elias is responsible for development, integration and ongoing operation. We are happy to work with your internal IT team or IT service provider.

Which documents does your audit team chase most often?

In the free initial call, tell us how requests and confirmations run in your firm. We will show you where AI helps, what it costs and how it works with your audit software.
