Top 6 AI assistants for finance teams

1ChatFin

chatfin.ai

ChatFin is an AI agent platform for finance and accounting teams that connects to a company's existing ERP and runs close, AP, reconciliation and reporting work, routing each posting to a named approver.

Best for

Finance and accounting teams on NetSuite, SAP, JD Edwards, Acumatica, Dynamics 365, Oracle Fusion or Sage Intacct that want AI agents to read and post inside that ERP, with a person approving each posting.

What it does

• Answers ad hoc finance questions in natural language with drill-down, and generates financial reports, KPI dashboards and variance reports.
• Agents draft journal entries and accruals, a person approves before anything posts to the ERP, and every action is logged for audit.
• Matches transactions across bank statements, ledgers and intercompany accounts, and flags and prioritizes exceptions.
• Writes variance narratives, spots trends and anomalies, and produces forecasts from live ERP data.

AI features

Analytics AI

Module that produces variance analysis with written commentary, anomaly detection, forecasts from live ERP data, and KPI monitoring with alerts.

Automation AI

Module that runs multi-step workflows such as AP processing and multi-entity close coordination, with human approval gates and exception routing.

NetSuite MCP server (open source)

MIT-licensed Model Context Protocol server published by ChatFin Labs that lets MCP clients such as Claude Desktop retrieve NetSuite accounts, balances, invoices, bills and journal entries through SuiteQL and RESTlets.

SAP Business One MCP layer

ChatFin describes an MCP server on the SAP B1 Service Layer that exposes AP invoices, journal entries, business partners and inventory items to Claude, running under a B1 service account and its authorization groups.

Connects to

Oracle NetSuite, Oracle Fusion Cloud, JD Edwards EnterpriseOne, SAP Business One, SAP S/4HANA, Microsoft Dynamics 365, Sage Intacct, Acumatica, QuickBooks Online, Workday, Snowflake, Epicor Kinetic, Infor CloudSuite, Blackbaud Financial Edge NXT.

Connects through each system's own APIs (for example SuiteQL for NetSuite, Service Layer for SAP Business One, AIS for JD Edwards) under a dedicated service account that keeps the ERP's role permissions, and queries data in place rather than copying it.

The About page says on-premise and hybrid ERP setups are supported.

Data controls

Queries ERP data in place under a dedicated service account that keeps the ERP's role permissions, and a person approves each posting. The site shows SOC 2 and ISO 27001 badges but did not link a trust page or audit report when checked.

Pricing

No pricing is published; ChatFin sells through demos, and its free trial page says the trial is open to selected companies only.

Watch out for

Independent reviews are scarce: ChatFin's Product Hunt listing showed no reviews when checked, so ask for customer references before buying. It works only on the ERP and data systems it connects to.

2Perplexity Enterprise

Perplexity AI. perplexity.ai

AI research assistant that returns cited answers from the web and from connected company files.

Best for

Teams that need sourced answers and the admin controls IT asks for; Enterprise Max is the higher tier.

What it does

• Cited web research with premium source citations from PitchBook, Statista and others.
• File Connectors search Google Drive, OneDrive, SharePoint, Dropbox and Box, including XLSX, XLS, CSV and Google Sheets files, without copying them for standard search.

AI features

Pricing

Enterprise Pro $34 per seat/month billed annually.

Watch out for

Several controls finance and IT teams expect are not self-serve: SCIM, audit logs, role-based access control and data retention configurability are marked 'Contract required' on the pricing comparison.

3ChatGPT Business and ChatGPT Enterprise

OpenAI. chatgpt.com

OpenAI's AI assistant, offered to companies as a shared workspace with chat, file analysis, deep research, connected apps and admin controls.

Best for

Business suits growing companies that want a shared workspace with company files and admin controls; Enterprise adds the security and support terms larger companies ask for.

• Data analysis, file uploads, interactive tables and charts, and deep research are included in Business and Enterprise; the Business plan's reasoning context window is listed at 256K tokens (about 320 pages of input).

AI features

ChatGPT for Excel / ChatGPT for Google Sheets

Launched in beta on 5 March 2026 on GPT-5.4; Google Sheets beta followed on 22 April 2026; both generally available on 5 May 2026, powered by GPT-5.5. In Enterprise workspaces access is off by default and admins enable it by role.

Pricing

Watch out for

Spreadsheet output still needs review: OpenAI's own launch post lists known limitations in which outputs 'may occasionally require cleanup' and 'complex formulas or edge cases may still require manual refinement'.

4Claude (Team and Enterprise)

Anthropic. claude.com

Anthropic's AI assistant on web, desktop and mobile, with Team and Enterprise plans for organizations.

Best for

Team covers 2 to 150 people; Enterprise is for larger companies.

What it does

• Claude for Microsoft 365: builds models in Excel with real formulas across multiple tabs, pulls numbers from a Word brief, and carries context across Outlook, Word, Excel and PowerPoint. Changes show as tracked changes in Word and highlighted cells in Excel.
• Create and edit files with code execution, plus Research, Projects and enterprise search across the organization (Team and Enterprise).

AI features

Claude for Excel (now part of Claude for Microsoft 365)

Launched on 27 October 2025 as a beta research preview: a sidebar in Excel that reads, analyzes, modifies and creates workbooks and explains each change with links to the cells it touched. The current pricing page lists Claude for Microsoft 365 as a feature of paid plans.

Watch out for

Enterprise cost is not fixed per seat: the plan is 'Seat price + usage at API rates', and Anthropic says 'usage cost scales with model and task', so heavy analysis raises the bill.

5Microsoft 365 Copilot (including Copilot in Excel)

Microsoft. microsoft.com

Microsoft's AI assistant built into Word, Excel, PowerPoint, Outlook and Teams, grounded in an organization's Microsoft 365 data through Work IQ.

Connects to

SharePoint, OneDrive, Microsoft Teams, Outlook, Excel, 100+ Copilot connectors for line-of-business data.

Pricing

Microsoft 365 Copilot: $30.00 per user/month paid yearly, or $31.50 paid monthly with an annual commitment.

Watch out for

It is an add-on, not a standalone tool: the Copilot Business add-on 'is available only to existing Microsoft 365 customers with an eligible Business plan', requires an annual commitment, and agent usage is metered on top.

6Gemini in Google Workspace

Google. workspace.google.com

Google's AI built into Gmail, Docs, Sheets, Drive and Meet, plus the Gemini app and Gemini Notebook, included in Google Workspace business plans rather than sold as a separate add-on.

Spreadsheet AI depends on the tier: on Google's plan comparison, Gemini inside Workspace apps such as Docs and Sheets is listed for Standard and Enterprise, while Starter gets Gemini in Gmail plus the Gemini app and Gemini Notebook.
