AI for CFOs: how to bring AI near your finance stack without losing sleep

CFOs are asked two things about AI at the same time. The board wants to know why finance isn't moving faster. The audit committee wants to know what could go wrong if it does.

Both questions are fair. Finance is the function where AI can remove the most manual work (matching, reconciling, chasing, reporting) and also the function where a wrong action has a direct cost. Getting AI near the finance stack is less about picking the best AI tools and more about deciding what AI is allowed to do, on which data, and who checks it.

This guide covers the AI use cases that matter for finance leaders, the risks to control, and a practical approach to AI adoption in the finance function.

Where finance stands with AI today

Adoption is real but uneven. Gartner's 2025 survey of 183 CFOs and senior finance leaders found that 59% use AI in their finance function, barely up from 58% the year before (Gartner, November 2025). Gartner points to complexity, data and talent challenges as the reasons adoption has levelled off, with inadequate data quality and availability as the largest obstacles. A quarter of respondents were unsure how to move from planning to piloting.

At the same time, 67% of finance leaders already using AI said they were more optimistic than the year before. The gap is not belief in AI; it's getting from a first experiment to something the finance team can rely on every month. That gap is the same one that stalls most AI transformation projects.

How AI is changing the finance function

AI changes finance work in three layers.

Transaction processing

The highest-volume, most rules-based work: invoice processing, matching, coding, expense management, payment runs. AI can read documents that don't follow a template, apply your rules, and route exceptions to a person. This is where most time is recovered, and where finance automation usually starts.

Close and reporting

The month end close is a chain of reconciliations, checks and follow-ups across systems and people. AI can run reconciliations as transactions arrive instead of in a month-end push, prepare variance explanations for review, and chase missing information before the deadline rather than after it.

Analysis and decision support

Forecasting, cash flow analysis, scenario planning and board reporting. Here AI is a co-pilot rather than an operator: it gathers data across systems, drafts the analysis and surfaces anomalies, and the finance team decides.

AI use cases for CFOs

A real example: 80–85% of accounting operations, same team

A multi-brand fashion retail franchise with 11+ stores and 250+ employees ran a high-volume daily business with a five-person accounting team. Bank reconciliation, voucher reconciliation, bookkeeping and payment chasing were all done by hand.

With Growy's finance reconciliation agent, agentic workflows now handle 80–85% of accounting operations, across 11+ stores reconciled daily. The workflow runs in three moves:

1. Match. Bank transactions and vouchers are reconciled against the books as they arrive. Clean matches are booked without manual review.
2. Flag and route. Unmatched or partial lines are flagged with the agent's context and routed to the accounting contact responsible for that shop, entity or account.
3. Chase. Missing amounts are followed up with the responsible shop and tracked to resolution. Anything genuinely ambiguous stops for human confirmation instead of guessing.

The accounting team stayed the same size. Its work moved from matching lines to resolving the exceptions that need judgment. As the use case page notes, 80–85% is the figure for this customer's processes and volumes; any business needs its own baseline.

The risks CFOs should control

The concerns finance leaders raise about AI are reasonable. Each one has a concrete control.

Wrong numbers, confidently presented

Language models can produce plausible but incorrect output. In finance, plausibility is not enough.

Control: AI should work from your systems of record, not from memory, and every output should be traceable to its source data. For calculations, the system should use the ledger and deterministic rules, with AI handling reading, matching and drafting. Steps below a configured confidence threshold should escalate rather than proceed.

Actions without authority

An AI agent that can post entries or release payments needs the same segregation of duties as a person.

Control: role-based access control (RBAC). At Growy, agents act through your connected systems and inherit their existing role-based permissions, so an agent can't do anything a properly permissioned user couldn't. Inside Growy, administrators control who can build, run, approve and view.

No trail for the auditors

If nobody can explain what the AI did, the process won't survive an audit.

Control: an audit trail of every step. Growy logs every workflow run at workflow level (trigger, timing, path, outcome) and at node level (inputs, outputs, systems touched, approvals, where a run stopped). Approvals are recorded with the approver and the time, and actions are recorded both in the source system and in Growy.

Errors at scale

A manual mistake affects one invoice. An automated mistake can affect a thousand.

Control: human in the loop on high-impact steps. Growy's AI governance uses three documented autonomy levels per agent: assistive (the agent drafts, a person acts), supervised execution (named steps need approval) and delegated execution (the agent acts within pre-agreed limits and escalates the rest). Irreversible, externally binding or financially material actions stay behind human approval. Start at the first two levels and extend autonomy as accuracy is proven.

Data leaving your control

Finance data is sensitive: salaries, margins, customer terms.

Control: know where data is processed, whether it is used to train models, and how access is logged. Growy encrypts data in transit (TLS) and at rest, separates client data logically, and does not use company data to train, fine-tune or improve any general-purpose model; its model providers are contractually barred from training on or retaining customer data. The finance agents are EU-hosted and built for the EU AI Act. See security and GDPR and the EU AI Act.

How AI improves financial decision making

Automation saves time. Better decisions create value. Once transaction processing and the close run on reliable AI workflows, the finance team can use the same data foundation for analysis.

• Real-time financial visibility. When reconciliations run daily, the CFO doesn't wait for month end to see cash, receivables and payables. Financial data is current every day.
• Cash flow and working capital. AI can forecast cash flow from open invoices, payment behaviour and pipeline data, and flag customers likely to pay late before it happens. That turns working capital management from reporting into action.
• Forecasting and planning. Data driven forecasts update as actuals come in, and AI can draft the variance analysis for the FP&A team to review, instead of the team building it from scratch in Excel.
• Risk management. Pattern detection across transactions highlights duplicate payments, unusual vendor changes and possible fraud for review.
• Daily briefings. An operations reporting agent can pull system data overnight, flag anomalies and deliver a daily briefing to finance leaders.

The common thread: AI does the gathering and the first analysis; the finance team brings judgment, context and the decision.

The CFO's role in AI transformation

In many companies, the CFO is becoming one of the main sponsors of AI across the enterprise, not only in finance. Three reasons:

1. Finance owns the business case. Every AI initiative needs a clear return on investment. The CFO is best placed to define how value creation will be measured and to stop projects that don't deliver.
2. Finance owns controls. The disciplines AI needs (segregation of duties, approval matrices, audit trails) are finance disciplines. Bringing them into AI governance early makes enterprise-wide AI safer.
3. Finance is a natural proof point. A finance function that reconciles daily with fewer errors is the most credible internal case study for AI in other functions.

For finance leaders, this is also a career opportunity. The CFO who leads the finance transformation with AI moves from reporting on the business to shaping how it operates.

How CFOs can adopt AI without losing control

1. Start where the rules are clear and the volume is high

Invoice processing, reconciliation and expense checks are good first use cases: the rules exist, the volume justifies the effort, and success is easy to measure. Leave forecasting and strategic analysis for later, once the team trusts the data foundation.

2. Fix the data the process depends on

Gartner's survey names data quality as the biggest obstacle. You don't need to clean every system, but the process you automate needs one authoritative source for each piece of information: vendor master data, chart of accounts, approval matrix, policies. This is what a company brain provides for finance: connected sources, clear owners, permissions respected. See also how to create a single source of truth.

3. Keep your finance stack; put AI on top

Replacing an ERP to "get AI" is rarely the answer. AI workflows should connect to the ERP, accounting software, bank feeds, spreadsheets and email you already use, and work inside them. Growy reads from and writes to existing systems, including SAP, Xero, QuickBooks, Stripe, Microsoft Excel and Snowflake, through its integrations, with no migration.

4. Design approvals before automation

For each step, decide: AI completes it, AI prepares and a person approves, or a person does it. Write it down. This is the document your auditors and your team will ask for, and it's the fastest way to get compliance on board.

5. Measure what the board cares about

Days to close, cost per invoice, share of transactions processed without manual touch, exceptions per month, working capital impact. Capture the baseline before going live.

6. Train the team on the new roles

When AI takes the matching and chasing, finance staff become reviewers and problem solvers. That is a better job, but it is a different one. Make the change explicit, and involve the team in defining the rules the AI follows.

Common challenges when CFOs adopt AI

• Data spread across too many systems. Several ERPs after acquisitions, spreadsheets for the gaps, manual adjustments. Start with one process and the data it needs, not a company-wide data project.
• Unclear ownership between finance and IT. Finance should own the process and the rules; IT should own security and integration. Write it down.
• Pilot fatigue. Teams that have seen several AI demos with no result become sceptical. Choose a first use case where results are visible within weeks.
• Skills. Finance teams need to learn how to review AI output and define rules, not how to code. Plan time for it.
• Over-reliance on one vendor's roadmap. Prefer approaches that work with your existing finance stack, so you can change components later.

Choosing AI tools for finance

Most AI finance tools fall into three categories:

• Point solutions for one task (AP automation, expense management, forecasting). Fast to deploy, but each brings its own data silo and its own rules.
• Features inside your ERP or accounting software. Convenient if you live in one system, limited when processes cross several.
• Platforms that orchestrate workflows across systems. They connect the tools you already have and run multi-step processes end to end, with governance built in. This is where AI agents for finance sit. Agents, not chatbots: the difference is explained in AI agent vs chatbot.

Questions to ask any vendor:

1. Can every output be traced to its source data?
2. How are permissions scoped per agent, entity and account?
3. Where can we put human approval, and can we change it ourselves?
4. What does the audit trail record, and can auditors read it?
5. Which of our systems does it integrate with today?
6. Is our data used to train models?
7. How long until the first process is live?

What a CFO-ready AI workflow looks like

Take supplier invoices. Here is the workflow Growy shows on its homepage:

1. Receive. Invoices arrive by email or through the supplier portal. The workflow picks them up automatically.
2. Extract. An agent reads each invoice and extracts 12 fields, whatever the layout, and matches them to the purchase order.
3. Check. Tolerances and duplicates are checked against your rules.
4. Approve. Invoices above €5,000 need sign-off from a person; the approver gets the evidence the previous steps used.
5. Post. The ledger entry is posted and the invoice archived.

Every step is written to the audit trail, and exceptions go to the right person with context. Nothing here requires the finance team to change systems. What changes is that people handle the exceptions instead of every invoice.

A 90-day AI roadmap for the finance function

• Days 1–30: choose and prepare. Pick one high-volume process (supplier invoices or bank reconciliation). Map it, capture the baseline (cost per transaction, cycle time, error rate), and confirm the source of truth for vendor data, chart of accounts and approval rules.
• Days 31–60: build and test. Connect the systems, configure the AI workflow, set human approval thresholds and audit trail requirements with your controller. Run it in parallel with the manual process and compare results.
• Days 61–90: go live and report. Switch to the automated workflow for a defined scope, review exceptions weekly, and report results to the executive team in the same metrics as the baseline. Choose the next process based on what you learned.

Ninety days is enough to prove value on one process without a large transformation programme, and to give the board a concrete answer on AI in finance. Growy's pricing follows the same logic: no fixed plans, a quote scoped to the processes, the tools to connect and the level of autonomy you choose.

Frequently asked questions

How can CFOs use AI?

The highest-value uses are invoice processing, bank reconciliation, payment chasing, expense checks, the financial close and forecasting support. Start with high-volume, rules-based processes, then extend to analysis once the data foundation is trusted.

What are the risks of AI in finance?

Incorrect outputs presented with confidence, actions taken without proper authority, missing audit trails, errors repeated at scale and sensitive data leaving your control. Each can be controlled with source traceability, role-based access, audit trails and human approval on high-impact steps.

Will AI replace finance teams?

No. It removes repetitive tasks such as matching, chasing and data entry. In the fashion retail example above, the five-person accounting team stayed the same size while 80–85% of accounting operations became automatic.

What is the best AI tool for CFOs?

Finance processes cross several systems: bank feeds, the ledger, the ERP, email and spreadsheets. The right tool orchestrates AI workflows across your existing finance stack, with role-based access, human approval and an audit trail built in, instead of adding another silo. That is the approach behind Growy's finance reconciliation agent.

How do you keep AI auditable in finance?

Log every step: data read, rule applied, action taken, approver and timestamp. Limit each agent's permissions to its task, and require human approval on payments, entries and master data changes.
