We do not trust AI for finance. We trust the eval suite.
Finance Ops installs as a department under your eval discipline. The agent does not get a say in journal entries. Variance commentary lands in your voice. Hard-write actions never graduate to auto-execute — ever. Month-end compresses from 8–12 days to 3–5. SOC 2 Type I evidence by month six on the lighthouse install. Your audit committee is asking harder questions every quarter; this is the answer.
Month-end takes 8 to 12 days. The close is a fire drill the third week of every month. FP&A patches data lineage every Monday. Cash visibility lives in a different sheet than the GL. Your audit committee asks the same questions every quarter and your team types the same answers by hand. The AI vendors already onsite cannot tell you which numbers they touched. You have already filtered ten 'AI for finance' widgets this year. You will filter the eleventh.
Finance Ops installs as a department on the operating system. Wired to NetSuite, the GL, the FP&A sheets, the bank feeds — the accounting substrate already in use. Held to evals you author at install — accuracy, lineage completeness, anomaly detection. Six named agents: Month-End Close, AR/AP Hygiene, Variance & Commentary, Vendor Spend, Board Pack, Compliance. Every write is gated by an eval or a human approval. Hard-write actions never graduate to auto-execute. Ever. We never auto-write to the ledger; we never reconcile without showing our work.
Month-end compresses from 8–12 days to 3–5 inside one quarter. Variance commentary lands in your voice — based on prior commentary patterns, not vendor boilerplate. Board pack prep compresses from 5–8 days to 1–2. Lineage stays clean and exportable. The audit committee receives the eval results in the quarterly pack — the same way SOC 2 controls work, except the control surface is the AI department itself. You stop patching the close and start running it.
Finance Ops never auto-executes a write to the ledger.
Hard-write actions never graduate to auto-execute. Every journal entry, every reconciliation, every adjustment is human-approved during the install and for the foreseeable life of the engagement. The department proposes; the controller signs. The eval suite is the auditable artifact — versioned, replayable, exportable to your auditor. The same discipline that defended Casetext through the $650M Thomson Reuters acquisition. This is structural to the work, not a setting that gets flipped later.
