# AI for Finance, Accounting & FP&A

URL: https://justuju.org/role/finance/
For your role

AI now drafts reconciliations, variance notes and forecasts, and reads contracts and filings in bulk. Finance keeps its oldest rule: a number counts only if you can trace it and someone signs for it.

## How AI is changing this work

- The close gets agents that match transactions, prepare reconciliations and explain variances for a preparer to review.
- Analysis shifts from building the spreadsheet to checking one an assistant built.
- Research across filings, contracts and transcripts takes minutes, with a citation on each claim.

## Key layers, most important first

### 1. Layer 9 · Applications & Interfaces

URL: https://justuju.org/layer/applications-interfaces/

Why it matters: Finance lives in spreadsheets, the ledger and the planning tool. AI arrives as an assistant inside each, so the first gains need no new system.

What to do here:
- Spreadsheet assistant: Describe the analysis; the assistant builds formulas, pivots and charts in the workbook and shows each step. (see https://justuju.org/concept/copilots/)
- Ask the plan a question: Query budgets and forecasts in plain words and get the answer with the source model and date. (see https://justuju.org/concept/embedded-ai/)
- Cited research: Search filings, transcripts and broker notes; accept only answers that link to the passage. (see https://justuju.org/concept/chat-assistants/)

### 2. Layer 8 · Agents

URL: https://justuju.org/layer/agents/

Why it matters: The close and payables are long, rule-bound, multi-step jobs: the kind agents do well. They are also where an unchecked action becomes a misstatement.

What to do here:
- Prepare, then sign: An agent gathers support, flags odd items and builds the reconciliation; a named person reviews and signs. (see https://justuju.org/concept/agent-loop/)
- Invoice handling: Agents code invoices, check them against orders and flag fraud signals before approval. (see https://justuju.org/concept/agent-loop/)
- Same controls as staff: Agents get roles, limits and separation of duties like any user, and every action is logged. (see https://justuju.org/concept/agent-permissions/)

Examples as of 2026-11-11: BlackLine Verity (https://www.blackline.com/products/verity-ai/); Ramp Bill Pay agents (https://ramp.com/accounts-payable); Finance Agent for Excel (Microsoft) (https://learn.microsoft.com/en-us/copilot/finance/welcome)

### 3. Layer 7 · Orchestration & Tooling

URL: https://justuju.org/layer/orchestration-tooling/

Why it matters: A language model should never do your arithmetic from memory. This layer makes it fetch figures from the ledger and compute with real tools.

What to do here:
- Numbers come from tools: The model calls the ledger, the warehouse or a calculator for every figure instead of recalling it. (see https://justuju.org/concept/tool-use/)
- Documents in a grid: Run the same questions across hundreds of contracts or filings and check answers cell by cell against the source. (see https://justuju.org/concept/rag/)
- Tie-out tests: Keep a set of questions with known answers from last quarter and re-run it before trusting a new setup. (see https://justuju.org/concept/guardrails-evals/)

Examples as of 2026-11-11: Hebbia Matrix (https://www.hebbia.com/blog/how-private-equity-teams-use-hebbia); Model Context Protocol (MCP) (https://modelcontextprotocol.io/specification/2026-07-28/)

### 4. Layer 5 · Foundation Models

URL: https://justuju.org/layer/foundation-models/

Why it matters: Models differ most on exactly what finance needs: multi-step reasoning and care with figures. Picking the right kind of model changes the error rate.

What to do here:
- Reasoning models for analysis: Use a model that works through steps before answering for variance analysis and policy questions. (see https://justuju.org/concept/reasoning-models/)
- Know how it fails: A model predicts likely text. A plausible wrong number looks exactly like a right one. (see https://justuju.org/concept/next-token-prediction/)
- Where the model runs: For material non-public data, check where the model is hosted, or use open weights you run yourself. (see https://justuju.org/concept/open-weights/)

Examples as of 2026-11-11: Claude extended thinking (https://platform.claude.com/docs/en/build-with-claude/extended-thinking); DeepSeek-R1 (open weights) (https://huggingface.co/deepseek-ai/DeepSeek-R1)

## High-leverage use cases

- Reconciliation preparation: Agents match transactions, attach support and draft the explanation; preparers review exceptions only.
- Variance commentary: Draft budget-versus-actual notes from ledger data, with each figure linked to its source line.
- Contract and lease review: Pull payment terms, renewal dates and covenants from a document set into one table.
- Invoice coding and checks: Code, match and flag invoices before approval, with a person releasing payment.
- Forecast scenarios: Ask what-if questions of the planning model and compare scenarios side by side.

## Start here: the next 30 to 60 days

- Week 1 to 2: Pick one recurring report. Have an assistant rebuild it in a copy of the workbook and tie every number back by hand.
- Week 3 to 4: Pilot agent-prepared reconciliations on two low-risk accounts, with the usual reviewer.
- Day 30 to 60: Write the control: who reviews AI-prepared work, what evidence is kept, and which accounts are off limits.
- Day 30 to 60: Brief your auditors early on where AI touches the close.

## Risks and pitfalls

- Plausible wrong numbers: A model can state a figure that looks right and is not. One maker's own guidance warns against relying on its spreadsheet assistant for decisions in sensitive areas such as finance.

- Broken audit trail: If you cannot show where a number came from and who approved it, the time saved is lost at audit. Keep sources and sign-offs.
- Automated credit decisions: In the EU, AI that scores a person's creditworthiness is high-risk, with duties for the firm that uses it. Source: https://eur-lex.europa.eu/eli/reg/2024/1689/oj
- Leaking material information: Unreleased results pasted into a public chat tool are a disclosure risk. Use approved tools with contractual limits on data use.
- Agents with payment rights: An agent that can both approve and pay removes a control. Keep separation of duties for agents too.
