Finance decision workflow with Jev

Invoice and spend packets arrive as messy descriptions. The ledger, tax engine, and approval matrix still own money. Jev judges policy-fit of the narrative you paste. It does not post journals or calculate tax.

This unofficial page is the decision workflow slice of the finance approval decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to finance approval decisions decision workflow. Primary search language: Finance Jev decision workflow. Confirm patterns on docs.typesafe.ai. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.

Independent angle (cover ≠ clone): Typed exception + path questions with amounts extracted in code — not a clone of a finance-approvals product page or a rival AP-automation IA.

Finance use-case context

Finance approval decisions is a workflow, not a chat. Assemble a narrow state, ask the primitives below, and let the approvals orchestrator branch. TypeSafe’s docs say a good question is a snap decision a knowledgeable person could make in a few seconds — not an open-ended analysis of the spend / invoice narrative packet.

Hub: Use cases. Compare, when the other tool is the real job: finance approvals.

Decision Workflow inputs

Keep only fields the questions name:

{
  "packet": { "id": "ap-4401", "memo": "Rush SaaS renewal; vendor changed SKU names.", "vendor": "Acme Cloud" },
  "amounts": { "total_band": "5-15k", "currency": "USD", "extracted_ok": true },
  "policy": { "sole_source": "Sole-source allowed only with named waiver text.", "rush": "Rush = business-critical outage risk." }
}

Point instructions at packet.memo, policy.sole_source, policy.rush, amounts.total_band. Drop raw PDF bytes or invoice photos (not accepted); the full GL dump “just in case”.

Decision signals and actions

All of these share state and run in parallel. Code owns the graph:

def finance_route(ans, extracted_ok, total_cents):
    if not extracted_ok or total_cents is None:
        return "hold_extract"  # code, not Jev
    path = ans["path"]
    if path.confidence < FLOOR or path.choice == "other":
        return "review"
    if ans["policy_ok"].noul < T_OK or ans["exception_severity"].score >= 2:
        return "exception_queue"
    if total_cents >= HARD_CAP:  # arithmetic in code
        return "cfo_matrix"
    return f"path:{path.choice}"

Do not treat a Noul of 0.5 as a “medium” finance approval decisions score — it means yes and no are equally likely. Conjunctions stay in your code.

Guardrails and escalation

TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For finance approval decisions, treat auto_approve_under_cap as the high bar (posting an approval or payment instruction). Tune on labels — see offline evaluation.

Low confidence, path == other, or a policy miss → human or safe default; do not post an approval or payment instruction.

Evaluation and rollout notes

Shadow: ERP approvals unchanged; log Jev path beside the packet.

Canary: Auto-hold on extract failures + high severity only.

Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.

Official Python and JavaScript SDKs read TYPESAFE_API_KEY and retry documented 429/529. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.

FAQ

Does Jev execute the approvals orchestrator action? No. It returns typed answers. Your approvals orchestrator code calls queues, models, or humans.

Why several questions in one request? TypeSafe’s fan-out pattern: extra questions are cheap versus another HTTP call. Path + exception_severity + policy_ok share one state. Split a second call only when a later question needs an ERP flag you do not have yet.

Where is the rest of the Finance pack? Start with Finance input contracts and Finance confidence thresholds. Cluster hub: Use cases.

Can Jev replace the ERP approval matrix? No. Hard caps, SoD, and tax stay in finance systems. Jev scores the narrative remainder. See vs finance approvals.

Should we send the invoice image? No. System One state is text. Run OCR/extract elsewhere, then pass bands you trust.

What this page does not claim

• Not a ledger, tax engine, or SOX control.
• No leakage or cycle-time numbers.
• Not official TypeSafe.
• Official TypeSafe status, or that jev.pro issues API keys.
• That a schema-constrained answer is automatically factually correct.
