DATEV AI is the umbrella name for the AI features DATEV builds into its own software. DATEV eG is a German cooperative that makes software for tax advisers, so this matters to you if your firm works in DATEV or if your company sends its books to a German tax adviser who does. The main features are two automation services that generate booking suggestions in the DATEV cloud, one for invoices and one for bank transactions, and DATEV Copilot, an AI assistant for text, documents and research that DATEV currently offers only to tax advisers and auditors. All of them work inside a DATEV program, return a suggestion or a text, and in DATEV's own words leave responsibility with the person. An AI employee is something else: it works under its own user with limited rights, follows the firm's written rules across several programs, and the log shows what it did. The two don't compete. Where a DATEV feature does the job, you don't need an AI employee; where manual work remains between programs, the built-in AI won't remove it. Everything below is based on DATEV's German pages as of November 2026, not on a test of my own.
I built AI employees for a German tax advisory firm that work with their own user in the DATEV workplace; the full case is in AI Agents for Tax Firms: A Real Case. This page covers the question before that one: what does DATEV do itself, and when is an AI employee worth adding?
DATEV AI at a glance
The invoice automation service
DATEV says the service creates booking suggestions from digital invoices and from the firm's booking history in the DATEV data centre. Each suggestion is marked as reliable, uncertain or incomplete, and the firm can let reliable ones post automatically, with DATEV's note to keep checking the books as usual. Prerequisites include the standard German charts of accounts SKR03 or SKR04, DATEV Unternehmen online with receipts in its standard mode, open-item accounting and archiving in the DATEV data centre. If another system already feeds DATEV through one of its data services, DATEV says the automation service is often not needed. Those data services are explained in DATEV Integration: The Basics.
DATEV Copilot
DATEV describes Copilot as its central AI assistant for firm work: drafting, condensing and translating text, querying documents, research, and tasks and messages in MyDATEV Kanzlei. According to the DATEV shop, the licence is free of charge (as of November 2026); the legal research add-on and the MyDATEV Kanzlei features need their own licences. The limits are on DATEV's own page: tax advisers and auditors only, no spreadsheets or financial statements yet, no PDFs with images, a usage limit, and built-in knowledge as of September 2024. If you switch on internet research, the search query goes to Microsoft under Microsoft's privacy terms, which according to DATEV contain no special secrecy standards for professionals bound by confidentiality. DATEV says data isn't used for training and is processed in a DATEV-hosted area on Microsoft Azure in a European data centre.
Where DATEV AI stops
Every one of these features works inside one DATEV program, returns a suggestion, a text or an analysis, and ends with a person checking. DATEV says so itself: with Copilot, professional responsibility and the final decision stay with the person at all times. What none of them covers is the work between programs: opening the email, finding the tax notice in it, comparing it with the return, filing it, telling a colleague. That's what an AI employee is for. How AI in bookkeeping software compares across vendors is covered in AI Bookkeeping: What Actually Works Today.
The difference: an AI employee with its own user
An AI employee is an AI role with a fixed job, written rules and a human who signs off. At the tax firm in my case, the AI employees run on a server owned by the firm and have their own AI user in the DATEV workplace, with a clerk's rights and without rights to transmit filings or make payments. The log shows who did what, a person or the AI. Two workflows run on autopilot there: tax assessment notices, where one AI employee watches the mailbox and hands over and a second checks each notice against the firm's rules and files it, and click payrolls, meaning payroll runs with no change from the previous month. Anything no rule covers goes to the front office by email.
The last two rows are the point. If an AI works under a colleague's account, nobody can tell who did what. And because the AI user in the case has no rights to transmit or pay, the boundary is drawn in the system, not just written in an instruction. Monitoring deadlines, assessing notices legally and filing with the tax office stay with people.
Peter: what runs in my business
With Peter, my AI employee for receipts and bookkeeping, I'm on the other side, as a client of my tax adviser. His page says: "For me, Peter is not a small add-on inside the bookkeeping software; he is a separate AI employee. He operates the browser interface according to my documented process and can therefore learn workflows beyond built-in receipt recognition."
Peter is my AI employee and not a DATEV product. He works with DATEV in the browser, on my side as the client: every month he uses my login to upload the receipts to DATEV Unternehmen online and assign them there. That's my side as the client; in a firm where several people work in the same system, an AI belongs under its own user, as described above. He also screens new receipts, sets the receipt type, matches the credit card statement and reports what doesn't fit. He doesn't book entries; final approval stays with me and my accountant. Peter costs me nothing extra, just the Claude subscription, and he saves me hours every month. Peter can do the same for you; we have tested it. To set it up, you describe the workflow once, he learns it in a mode in which he only reads and takes screenshots, you test it on real cases, then you approve it. The browser side is explained in Claude in Chrome: How to Use the Extension and AI Agent for Bookkeeping and Inbox.
Template: DATEV feature or AI employee?
DECISION TABLE: DATEV FEATURE IS ENOUGH, OR AI EMPLOYEE ALONGSIDE
Posting incoming invoices
DATEV is enough if: digital receipts in DATEV, SKR03/04, open items
(invoice automation service)
AI employee if: invoices first have to be collected from email
and portals, named and uploaded
Stays with people: checking the entry, tax assessment
Posting bank transactions
DATEV is enough if: the bank data service runs
(bank automation service)
AI employee if: rarely needed
Stays with people: checking the entry
Drafts and summaries
DATEV is enough if: Copilot (tax advisers/auditors), text documents
AI employee if: the draft is part of a workflow across programs
Stays with people: sending, signing
Tax notices from the mailbox
DATEV is enough if: not part of the AI features above; check what
your tax program already compares
AI employee if: hand-over from the mailbox, check against the
firm's rules, filing, fallback route
Stays with people: legal assessment, objections, deadlines
Filing with the tax office, payments
AI employee if: never: the AI user doesn't get these rights
Stays with people: always

Approval: 1. count clean runs [set a number]
2. watch in parallel [period, who]
3. alone with closing report, approved by [name, date]
Professional secrecy and data protection
This isn't legal or tax advice. For a German firm, three rules come before any AI use: § 203 of the German Criminal Code makes tax advisers keepers of professional secrets and requires them to bind anyone assisting them to secrecy; § 62a of the Tax Advisers Act allows service providers access only as far as necessary, under a contract in text form with a confidentiality obligation, abroad only with comparable protection, and with the client's consent where the service serves a single engagement; and Article 28 GDPR requires a written data processing agreement with a processor offering sufficient guarantees.
For client data I offer my data lock. It sits between your team and Claude. Before a request goes to Claude, it replaces names and other details that point to a person with placeholders. Claude gets the placeholders instead of the names. When the answer comes back, the data lock puts the real names back in. It's ready for use and already in operation, and I set it up for each client individually; what your case needs, we work out together in a call. It lowers the risk, it doesn't remove your obligations, and no automatic detection finds every detail. More in AI and Privacy: What the AI Gets to See.
Frequently asked questions
What is DATEV AI?
DATEV's own AI features: mainly the invoice and bank automation services for booking suggestions and DATEV Copilot as an assistant, plus the objection generator and prototypes in the AI Workshop.
Can DATEV post invoices automatically?
Yes, entries the invoice automation service rates as reliable can post automatically, according to DATEV. DATEV still tells firms to check their bookkeeping as usual.
Can my company use DATEV Copilot?
Not directly. DATEV currently offers it only to tax advisers and auditors, and the pages cited here describe it in German. If your company works with a German tax adviser, ask whether the firm uses it and for which tasks.
Does an AI employee replace DATEV's features?
No, it works alongside them. Where the automation service suggests bookings, no AI employee needs to post them. It takes the work between programs, with its own user and its own log.
