AI in accounting: what GDPR allows in Austria
Where automation is safe, which three documents are required, and where the line is drawn on automated decisions about people.
The question "can invoices be uploaded to an AI service" sounds technical — but it is a legal one. Accounting documents contain personal data: names, amounts, addresses, employee details. The answer is therefore neither "yes" nor "no", but "yes, if properly documented".
What can be automated without risk
Invoice recognition (OCR), preliminary expense classification, matching payments to invoices, duplicate detection, draft posting preparation. All these tasks share one thing: a person reviews the result, and the final decision rests with a person.
Three documents you should have before you start
A data processing agreement with the service provider (Auftragsverarbeitungsvertrag) — mandatory if data leaves your own system. An entry in the processing activities register — a brief description of which data, for what purpose, and for how long. And an impact assessment if the processing is large-scale or sensitive.
Check separately where the data is physically stored. Transfers outside the EU require a legal basis — standard contractual clauses or an adequacy decision. The phrase "server in Europe" in marketing copy does not constitute such a basis.
Technically, AI in accounting is a matter of integration. Legally, it is a matter of who is responsible for an error. The answer is always the business owner.
Where the clear boundary lies
Automated decisions with legal consequences for a person, made without human involvement, are prohibited. In practice: scoring suppliers for internal prioritisation — permissible; automatically refusing a person something on the basis of an algorithm — not permissible. Equally, HR data should not be loaded into an external service "just to see what comes out".
One more detail that is often overlooked: retention periods. Tax documents must be kept for seven years, and if an AI service retains copies for longer or does not allow deletion, that becomes your problem, not the provider's.
Our approach is straightforward: we automate routine tasks, document the legal basis, and keep a person in the loop wherever a decision affects people. This delivers time savings without sleepless nights ahead of an audit.
