What This Agent Does
Entertainment receipts are a frequent focus during tax audits - because the tax requirements are complex and the error rate high. Mandatory fields (location, date, attendees, business purpose, amount), the 70% deduction rule, input tax deduction and reasonableness check - every receipt requires multiple verification steps.
The Decision Layer breaks entertainment receipt verification into nine decision steps. The AI Agent recognises entertainment receipts and assesses the plausibility of the business purpose. The rule engine checks mandatory fields, attendee list, 70% deductibility, input tax deduction and account coding. For the reasonableness check (unusually high amounts), the human decides.
The result: complete mandatory field verification for every receipt. Correct calculation of deductibility. Error-free input tax deduction. And during a tax audit, it is traceable for every entertainment receipt why it was processed that way.

Governance Notes
GoBD relevance: high - entertainment receipts are a frequent focus during tax audits. Paragraph 4 Abs. 5 Nr. 2 EStG defines the requirements: mandatory fields, attendee list, business purpose. The 70% deduction rule is deterministic. The reasonableness check requires human judgement because the tax principle of proportionality applies. Input tax deduction per Paragraph 15 UStG is checked separately.
§203 StGB-relevant data is encrypted end-to-end and never passed to AI models in plain text.
Process Documentation Contribution
Infrastructure Contribution
The Entertainment Expense Agent uses the receipt classification of the Travel Expense Agent and the posting logic of the Account Coding Agent. The mandatory fields check (EStG Paragraph 4 Abs. 5) becomes the standard pattern for all tax-sensitive receipts. The 70/30 split logic is reused across expense accounting.

Frequently Asked Questions
What happens when mandatory fields are missing?
The agent documents exactly which mandatory fields are missing and routes the receipt to the submitter. Missing attendees, missing purpose or missing location means the entire receipt is non-deductible. The agent flags this before creating the posting.
How is reasonableness assessed?
The agent checks the amount against configurable thresholds (per person, per occasion). Standard cases pass automatically. On breach, it is routed to the supervisor or accounting. The final assessment remains with the human because reasonableness is a discretionary decision.
Why is the plausibility check AI-assisted?
The business purpose is a free-text field. Checking whether a purpose like project meeting or customer acquisition sounds plausible requires language understanding. The AI Agent assesses plausibility - at low confidence, it escalates to a human.
