What This Agent Does

Invoice approval is the bottleneck between invoice receipt and payment. In many organisations, approval takes longer than the entire remaining invoice process - because invoices land with the wrong approver, budget checks are manual and overdue approvals are not escalated.

The Decision Layer breaks invoice approval into seven decision steps. Six are rule-based: approval authority, budget check, vendor block check, payment terms, escalation and batch approval. Only for budget overruns does the human decide - because this requires business judgement.

The result: invoices reach the correct approver immediately. Early payment discount deadlines are no longer missed because approvals are stuck. Standard cases can be processed as batch approvals. And the one decision that requires human judgement - the budget overrun - is made consciously and documented.

Decision Record and Right to Challenge

Every decision this agent makes or prepares is documented in a complete decision record. Affected parties (employees, suppliers, auditors) can review, understand, and challenge every individual decision.

Prerequisites

  • Defined approval matrix (amount, cost centre, product group)
  • Budget management in the ERP system
  • Vendor master data with block indicators
  • Delegation rules for escalation scenarios

Governance Notes

GoBD-compliant §203 StGB-compliant

GoBD relevance: medium - approval is not a tax decision but part of the internal control system (ICS). The approval matrix maps signing authorities and budget responsibilities. For budget overruns, the decision remains with the human because business judgement is required - this is not a limitation of the agent but correct governance.

§203 StGB-relevant data is encrypted end-to-end and never passed to AI models in plain text.

Process Documentation Contribution

The Invoice Approval Agent documents: the determined approver (with rule reference), the budget check result, the vendor status, the payment terms validation, any escalations and the final approval decision. For auditors, it is traceable that every invoice was approved in accordance with the ICS.

Infrastructure Contribution

The Invoice Approval Agent builds the approval routing reused by all workflow agents. The escalation logic becomes standard for all agents with deadline monitoring. The batch approval logic is used by the Payment Run Agent. The budget check pattern becomes the standard across the entire Finance organisation.

Frequently Asked Questions

How flexible is the approval matrix?

Fully configurable. Approval levels by amount, cost centre, product group, vendor class. Delegation rules for absences. Batch approvals for recurring standard cases. The matrix is versioned - changes are traceable.

What happens when discount is at risk?

The agent monitors discount deadlines. When an approval is outstanding long enough to jeopardise the discount, it automatically escalates. The escalation documents the financial impact of the discount loss.

Can approvals be granted on mobile devices?

The approval interface is device-independent. The approver sees the relevant information (invoice, budget status, contract data) and can approve in seconds. The decision is documented with timestamp and user ID.
