Jev vs finance approvals

Finance approvals are segregation of duties, amount bands, and named approvers. Jev can ask whether a packet looks complete or inconsistent. It must not be the only signer.

Unofficial. Not accounting advice. Official jaggedness: keep money compares in code. docs.typesafe.ai.

Comparison scope

amount > policy is arithmetic. “Memo does not mention the related PO” is language. Split them.

Criteria that decide the architecture

Axis	Jev (System One)	Finance approvals
SoD / dual control	No	Wins
Amount vs limit	Code	ERP
Memo quality	Score / Noul	Reviewer
Posting	ERP	ERP

Decision quality and control

A forged-looking narrative is still a human/forensics problem. Jev can raise a flag, not a prosecution.

Integration trade-offs

ERP extract of memo + vendor name (no PAN) → Jev completeness Nouls → approver UI shows suggested issues. Approval API remains ERP.

TypeSafe’s public models page lists jev-1.13 at $0.042 per million input tokens with output tokens free — a vendor claim, not a jev.pro measurement. Confirm on the models page before you bid.

When each approach fits

Prefer Jev when

Packet text is the bottleneck for AP clerks

Prefer Finance approvals when

The rule is an amount, vendor blocklist, or SoD matrix

OCR/extract → Jev flags → ERP approval. Audit the human click.

What this page does not claim

Not a payments product.
No fraud-loss claims.
Schema-safe output is not the same as factual correctness.
No independent bake-off numbers live here.

When not to use Jev

Do not let Jev be the signer. SoD, amount bands, and named approvers stay in the ERP. A schema-safe looks_complete is not an approval.

Do not ask Jev which amount is larger, which currency wins, or whether the invoice exceeds policy. Convert and compare in code. Jaggedness: math.

Do not send PAN, full bank account numbers, or card data in state. Minimize to memo + vendor name + already-redacted totals.

Skip Jev when the packet is already structured (PO match, 3-way match) and there is no residual language, or when the controller’s policy forbids a model in the path.

Pairing-specific failure modes

Snap risk treated as posting. A high Noul auto-posts. The audit trail then has no human click.
Date/due identity. “Net 30 from 12 Mar” is a date library. Extract; do not ask Jev if it is overdue.
OCR garbage as evidence. Bad extract (invoice OCR) plus a completeness Noul is theater. Fix the span first.
Alias drift on period close. Pin jev-1.13.0 after you fit flags; jev-latest mid-close changes the clerk queue.

Production sketch

ERP extract: vendor, memo, redacted totals, PO id. Amount-vs-limit and vendor blocklist run in code first.
Residual language → completeness / inconsistency Nouls or a Score. Pin jev-1.13.0. Log response.model.
Approver UI shows suggested issues. The click that posts is the ERP approval API — always.
Low confidence or SoD-sensitive vendors → extra reviewer, not a quieter flag.
Workpaper stores criteria SHA, model id, and the human decision. That is the control. See procurement workflows for the purchase-side twin.

FAQ

Can Jev approve invoices? Only if your controller’s policy says a model may — we assume no.

Multi-currency? Convert in code. Do not ask Jev which amount is larger.

Is this fraud software? No. Flags only. No loss-rate claims.
