An incoming invoice contains supplier, amounts and dates, but processing also depends on the purchase order, receipt of goods or services, contract, cost centre, tax treatment and approval authority. OCR can read a field. Business AI can prepare context and isolate an exception, but financial accountability must remain clearly assigned.
The distinction between preparation and posting matters. Initially, AI can recommend while an accountable person confirms. Only after enough real cases and a clear error analysis should low-risk standard cases receive more automation. A rare exception should not be forced through a rule merely to make the automation rate look higher.
The OECD accountability principle highlights traceability of datasets, processes and decisions throughout the AI lifecycle. In finance, that means connecting every recommendation and action to its source, rule, role and confirmation. This is not a claim of legal compliance; specific obligations must be assessed for the use case and applicable regulation.

Good finance AI does not hide complexity. It turns it into a clear, verifiable exception that an accountable person can understand quickly.
