General & contract

10 questions
Why is the offer aimed exclusively at business customers?
Our offer is aimed exclusively at companies, self-employed professionals and freelancers, because our software and services have been developed specifically for business use. We provide features, support and pricing tailored to the needs of business customers. Consumers within the meaning of the law (i.e. private individuals acting for private purposes) therefore cannot use our offers.
What is the minimum contract term?
The minimum contract term is 12 months. After that, the subscription renews automatically unless notice of cancellation is given.
Can I switch between packages?
Yes, an upgrade is possible at any time. Please contact our support team to discuss the details.
How do I cancel my contract and what notice periods apply?
Our contract has a term of 12 months and renews automatically for a further year unless cancelled in time. Notice of cancellation must reach us at least 1 month before the end of the contract term. If no timely cancellation is received, the contract is automatically extended by a further 12 months.

Example: If the contract was concluded on 1 January of a given year, the cancellation must be received by 30 November of that contract year at the latest to avoid renewal. Cancellation can be submitted in writing by email. You will receive a confirmation once the cancellation has been processed.
What payment methods are available?
Payment is currently made by invoice. Further payment methods will follow shortly.
What is the payment interval?
After your order, depending on the payment interval you chose, you will receive either an annual invoice for the total amount covering 12 months by email, or monthly invoices starting with the first payment, also by email. Please note, however, that the monthly option is slightly more expensive overall. Annual payment offers the lower price per month.
Where can I find the full Terms and Conditions?
The General Terms and Conditions of Business and Use of Semitax GmbH are available here: Terms and Conditions of Semitax GmbH (PDF).
What happens to my data when the contract ends?
Before your contract ends, you should back up your data yourself using the export function in AUDIPY. When the contract ends, access to AUDIPY is blocked. Your working data remains stored locally with you in an open format (Parquet) and can also be opened with other tools. Semitax does not store AI prompt inputs or AI outputs on its servers, so after the contract ends there is no data left that could be handed over.
How quickly does Semitax respond to technical issues?
Semitax distinguishes three fault classes and endeavours to respond quickly, without delay for faults that prevent operation. The details are set out in our Terms and Conditions. Faults can be reported via the ticket system or by email.
Can I try AUDIPY before buying?
Yes. On request, we show you AUDIPY online in English, free of charge, using realistic sample data and answer your questions: request an English demo. You can also test the AI assistant AMY directly in your browser at any time. For an individual test with your own data, please get in touch.

Technical requirements

6 questions
What are the technical requirements?
AUDIPY has no special system requirements. The application is designed to run smoothly on all current Windows systems from Windows 10 onwards.

Basic requirements:
Windows 10 or higher
Internet connection (for online activation and updates, where applicable)

For larger installations or use in a corporate environment, we recommend coordinating with your IT department. Full details can be found in the AUDIPY installation guide.
What about installation on Apple devices?
A direct installation of AUDIPY on macOS is currently not planned. However, AUDIPY can generally be used on Apple devices via a virtual Windows environment (VM). This requires a virtual machine with a full Windows operating system, set up for example with Parallels Desktop, VMware Fusion or VirtualBox.

It is important that the virtual machine has a unique CPU ID. An internet connection within the VM is recommended for activation. If no internet connection is available, a manual activation is possible as an alternative. Hardware virtualisation (VT-x or AMD-V) should also be enabled on the host system.

We recommend keeping the virtual machine permanently, as frequent changes or resets can cause licensing problems.
What should I know about virtual machines (VM)?
A virtual machine (VM) lets you run an operating system such as Windows within an existing system (e.g. macOS, Linux or another Windows), regardless of the actual operating system of your device. This requires virtualisation software such as Parallels, VMware or VirtualBox.

A full Windows system can be installed and used within the VM as if it were a separate computer. It is important that hardware virtualisation (VT-x or AMD-V) is enabled on the system and that sufficient system resources are available.
Is there data protection documentation for our IT?
Yes. On request, we provide your IT department and your data protection officer with comprehensive data protection documentation.
Can our IT switch off the AI functions centrally?
Yes. The administrator can switch off the AI centrally. We can also agree with you individually which modules are used in your organisation.
How is AUDIPY rolled out to many computers?
Centrally via a silent installation. We provide updates to your IT department, which then installs them as usual. You can request the documentation at any time.

Licences

14 questions
How do I receive the licence key?
After your order has been completed, the licence key is sent by email to the address you provided.
How do I activate the licence key?
Regardless of the subscription chosen, the licence key is always activated via the menu item “Online-Aktivierung” (online activation). An active internet connection is mandatory for this. In companies with several licences, this is often done centrally by the IT department.
What do I do if there is no active internet connection for registration?
In this case, please use the menu item “Manuelle Aktivierung” (manual activation). Please contact us in advance, as the required activation key (KEY) is created individually for you and sent to you.
Do I need a permanent internet connection to use AUDIPY?

That depends on the package you booked:

  • Basic: An internet connection is only needed for activation and deactivation and for updates. In normal operation, AUDIPY works completely offline; there is no regular online licence check.
  • AI Starter / AI Pro: The AI features require a permanent internet connection. AI requests go directly from your computer to Mistral AI, not via Semitax servers.
What can I do if there is no internet connection for activation?

Use the menu item “Manuelle Aktivierung” (manual activation). The program generates a request code that you send to us. From it, we generate an individual activation key that unlocks AUDIPY even without a direct internet connection. Please contact support@semitax.de in advance so that we can prepare the process.

Which hardware is my licence key tied to?

During activation, a hardware fingerprint of your workstation (PC/notebook) is created and linked to the licence key. This binding is to be understood as a permanent assignment of the licence to one workstation, not as a rotating pool used in turn by different people. Each user in the company therefore needs their own licence.

Simultaneous use of the same licence on several devices is not possible and is not permitted under section 20.2 of our Terms and Conditions.

How do I release my licence on a PC?

Directly in AUDIPY: In the Help ribbon, open the Info/About dialog, switch to the “Tools & Diagnose” tab and click “Manage License”. There you will find the “Lizenz deaktivieren” (deactivate licence) button. Deactivation sends an online revocation to our licence server and deletes the local licence key. The licence is then free for a new activation on another device.

An internet connection is required for deactivation. If the connection drops, you can simply trigger the process again. Activation and deactivation are idempotent, no data is lost.

Planned device move: I am getting a new PC, can I take my licence with me?

Yes. A device change in the sense of “my old workstation is being replaced by a new one” is of course provided for: deactivate the licence on the old device (in the licence dialog) and then activate it again on the new device. If deactivation is no longer possible (e.g. hard drive failure, theft, device already returned), just write to us at support@semitax.de. We will reset the binding on the server side, usually within one working day.

Important: Such a change is meant as a permanent move of the licence to the new device, not as rotating use by several people.

How often can I switch between licence packages (e.g. Basic ↔ AI Pro)?

Switching between licence packages is limited to one switch per calendar month. This prevents someone from, for example, upgrading to AI Pro for a few days each month and then switching back. For legitimate special cases (e.g. an additional switch in the same month for organisational reasons), please contact support@semitax.de; we will handle it manually.

This limit only applies to switching between tiers. Reactivating the same tier (e.g. after a PC change within the same package) is not affected.

How often may I move the licence between devices?

A licence is permanently assigned to one workstation. Changes are intended for legitimate reasons, such as a new PC, hardware replacement or a change of staff, and are handled smoothly in practice. What the licence is not: a rotating access used in turn by different people (e.g. “one AI Pro licence shared by 30 employees”). Such a multiple-users-with-one-licence approach is not permitted under section 20.2 of our Terms and Conditions. Activation and deactivation operations are logged on the server side and can be evaluated if misuse is suspected.

I have reinstalled Windows, will my licence still work?

In most cases, yes: the hardware fingerprint is generated in such a way that a pure software reinstallation does not change it. If AUDIPY nevertheless no longer accepts your licence after the reinstallation, write to us at support@semitax.de with your licence number. We will release the licence so that you can activate it on the newly set up system.

Tip: If you are planning a reinstallation and the old system is still running, deactivate the licence beforehand. You can then reactivate it immediately on the freshly installed system without having to contact support.

Hardware failure, theft or device already returned: how do I reactivate AUDIPY?

When hardware is replaced, the fingerprint may change and the licence has to be transferred. As long as the old device is still accessible, simply deactivate the licence there in the licence dialog and then activate it on the new PC. If that is no longer possible, write to us at support@semitax.de with your licence number. We will reset the binding on the server side, usually within one working day.

What happens to my licence when an employee leaves the company?

The licence stays with the company. As long as the employee's device is still accessible, deactivate the licence there and activate it on the successor's device. If the device has already been returned or reset, contact us and we will release the binding on the server side. A transfer to persons or companies outside your organisation is not permitted under section 20.3 of our Terms and Conditions.

I accidentally activated on two devices, what should I do?

That is not a problem: our licence server only allows one simultaneous activation per licence key. If you try to activate the same licence on a second device, a corresponding error message appears (“Too many activations”). The activation fails without anything being damaged. Deactivate the licence on the device that should no longer be used and then activate it on the target device.

AI functions

6 questions
Which AI features does AUDIPY offer?
AMY, the AI assistant in AUDIPY, offers comprehensive analysis features without any programming or formula skills. In the “Ask my Data” chat you can ask questions about your data, trigger calculations and run analyses. Quick actions include: describing data, data quality checks, journal analyses (Benford, rounding, segregation of duties), compliance checks and detecting anomalies.
What is the Code Gatekeeper?
The Code Gatekeeper is an automatic quality control for the code generated by AMY. Before a calculation is executed, it checks four criteria: correct intent, correct logic, freedom from errors and no unauthorised assumptions. The result is either an approval, a targeted follow-up question or an automatic regeneration.
Which AI models does AUDIPY support?
AUDIPY uses Mistral AI as its standard AI model, GDPR-compliant with zero data retention. Further models can also be integrated, such as OpenAI, DeepSeek, Google Gemini and others. GPT4All is available for completely offline operation.
Can AMY also create charts and visualisations?
Yes, AMY automatically creates charts and visualisations based on your data. You phrase your request in natural language in the chat dialog, AMY generates the code, the Code Gatekeeper checks it, and the result appears directly in AUDIPY.
Are my AI inputs stored on Semitax servers?
No. Neither your prompt inputs nor the AI outputs are stored on Semitax servers. Results can only be saved locally within AUDIPY using the export function. This also applies after the contract ends.
Can AI results contain errors?
Yes. The content provided by AMY is based on automated processes and can contain errors. It is intended as guidance and does not replace a careful manual review. AI results should not be used as the sole basis for decisions.

AuditPlus

5 questions
What is AuditPlus?
AuditPlus is an add-on module for AUDIPY with ready-made workflows: DataFlows for DATEV and SAP DART, the AuditSteps balance sheet structure, ForecastAudit and word search, as well as data model and dashboard templates. All analyses remain editable in AUDIPY. More about AuditPlus
Which licence do I need for AuditPlus?
AuditPlus requires an AUDIPY licence and can be combined with any package: Basic, AI Starter or AI Pro. The add-on costs from 39 € per month with annual payment, plus statutory VAT.
Do the dashboards also work without AI?
Yes. You can use templates, data models and dashboards with AUDIPY Basic as well. With an AI package, AMY additionally supports you with the data model, the dashboard and your own calculations.
How do I order AuditPlus?
Normally directly when ordering: choose your AUDIPY package and tick AuditPlus in the payment interval step. Already using AUDIPY? Then request AuditPlus via the add-on booking. We will check your term and send you a quote, pro rata until the end of your AUDIPY term.
Can I cancel AuditPlus separately?
Yes. AuditPlus runs with your AUDIPY licence, renews with it and ends no later than your licence. You can also cancel AuditPlus on its own with one month's notice to the end of the respective term. Your AUDIPY licence then continues unchanged.

Playbooks & AI agents

3 questions
What are Agent Playbooks?
Playbooks are predefined, automatically executable analysis workflows. You define a sequence of steps once, e.g. loading, cleaning and evaluating data, and can have it executed by an AI agent of your choice (e.g. Claude Code, Claude Cowork or OpenAI Codex) via the open MCP standard. Particularly useful for regular reporting or recurring audit processes.
Which AI agents does AUDIPY work with?
AUDIPY can be connected to AI agents via the open MCP standard (Model Context Protocol), e.g. Claude Code, Claude Cowork or OpenAI Codex. The agent can then load data, run analysis steps and work through Playbooks while AUDIPY runs in the background.
Which licence do I need to connect AI agents?
Connection via MCP is possible in all AUDIPY packages, including AUDIPY Basic. The AI agent itself, for example Claude Code, Claude Cowork or OpenAI Codex, runs on your own account with the respective provider.

XRechnung

7 questions
Is my invoice data transferred to external servers?
No, all your data stays on your computer. The program works completely offline and does not send any data to external servers.
Can I customise the output formats?
The basic output formats are fixed to ensure compatibility.
Which invoice formats are supported?
The program supports all common electronic invoice formats: XRechnung in all versions (2.0 to 3.0), ZUGFeRD from version 2.0, UN/CEFACT CII, UBL 2.1 and Factur-X.
Are there file size limits?
Individual files can be up to 100 MB in size. In batch processing there is no hard limit on the number of files.
Can I process files from network drives?
Yes, the program can read files from network drives and write to them. Please note, however, that processing over the network can be considerably slower. For optimum performance, we recommend copying the files locally before processing.
Can I validate several files at once?
The graphical user interface is optimised for validating individual files. To validate several files, you can use batch scripts or the command line parameters.
How can I increase processing speed?
The most important factors: use an SSD instead of a conventional hard drive, disable options you do not need, close other memory-intensive programs and process files locally rather than via network drives.
