Invoice Reviewer

1) Upload invoice

Upload a legal services invoice (PDF). The system will extract key fields and match it to a billing profile.

Processing stages

Data extraction → profile selection → compliance review

Architecture Insight

Stage 1 identifies the vendor and basic invoice fields via constrained extraction (JSON). User may then choose review profile and additional review categories. No browsing or external retrieval.

2) Extracted invoice data (validated)

Vendor
Invoice number
Invoice date
Service period
Total (excl. VAT)
VAT
Total (incl. VAT)
Payment terms
Payment deadline

Architecture Insight

The extraction model returns strict JSON which is schema-validated. If required fields are missing or ambiguous, the workflow could stop here and ask for human clarification in final version.

4) Review result

Compliance Assessment Summary

Objective checks + AI-assisted observations (for human review)

Query recommended

AI-assisted observations

Severity	Observation	Suggested follow-up
No AI-assisted observations.

Architecture Insight

Objective checks are rule-based and auditable. The LLM does not decide outcome of objective review and is limited to broader issue detection based on user-selected focus areas. Email drafting (optional) uses the findings list only — not the raw invoice.
