How to connect your books to Claude or ChatGPT

Works with your preferred AI assistant.

  1. Connect ReInvestWealth to your AI

    One connection, from your own Claude or ChatGPT account's connector settings.

  2. Ask, or tell it to work

    It answers from your ReInvestWealth data, or makes the change you asked for.

  3. You approve what it does

    It prepares a summary, and asks before it changes anything.

Accounting tasks in plain English

Ask, and your assistant does the work instead of handing you a to-do list.

  • Posts adjustments, ties the balance sheet, and locks the period. Flags what needs your judgment.

  • Creates, edits, and recategorizes transactions, and backfills whole years from any file.

  • Creates and sends invoices. Matches uploaded receipts to the transactions they belong to.

  • Reviews GST, HST, PST & QST numbers and balances. Starts the filing process and you e-file from the ReInvestWealth app.

  • Builds the report or projection, then drafts the client email. Connect your Gmail or Outlook to auto-send emails.

  • Reads transactions, receipts, the general ledger, and the trial balance, so answers come from your real numbers.

ReInvestWealth 5-star reviews on Capterra, Software Advice and GetApp

Questions about the MCP server

What is an MCP server?

An MCP server is a connector that lets an AI assistant (like Claude or ChatGPT) work securely in your accounting software.

What does the ReInvestWealth MCP server do?

It allows the assistant to make adjustments, fix transactions, send invoices, run reports, and perform other actions directly within your books. Across one business or multiple at the same time.

Is MCP reliable and secure?

Yes. It is an open standard, and the ReInvestWealth MCP server is tested and supported in both Claude (Anthropic) and ChatGPT (OpenAI). Any other MCP-capable assistant, including Codex, can connect to it as well.

How do I add the MCP server to Claude or ChatGPT?

From your assistant's connector or MCP settings: point it at the ReInvestWealth MCP server and sign in with the account you already have. No install, no API keys.

Can my firm use it across client files?

Yes, and it is the part we are most excited about. One instruction, every client file, at the same time. A cleanup that takes a junior a week runs in parallel across the whole book instead of one file after another.

The AI can change my books. What stops it going wrong?

It only reaches what you reach, it asks before it changes anything, and every change is an ordinary entry you can see and edit in the app. Nothing is hidden.

Is it available now?

Yes, it is live. Add it from your Claude or ChatGPT connector settings, sign in with your ReInvestWealth account, and it works in your books today.

How is this different from a QuickBooks or Xero MCP server?

QuickBooks and Xero now offer official connectors for Claude, and QuickBooks has one for ChatGPT. Each connects one company file at a time, QuickBooks is US-only, and Xero's is read-only. Ours offers full read and write capabilities, uses your existing permissions, and answers questions across all your ReInvestWealth profiles at the same time.

Do I need Claude Code, Cowork, or Codex?

None in particular. It is an MCP server, so it attaches to the account you already use rather than one specific app. Claude and ChatGPT are the two we test against.

Do I need a paid Claude or ChatGPT plan?

You need a Claude or ChatGPT account, and connecting a custom MCP server depends on your plan there (Anthropic's and OpenAI's call, not ours). Check connector support on your plan with them.

Get your books ready for it.

The MCP server is only as good as the books behind it. Start free, let the AI keep them current, and connect your assistant the same day.

Cancel anytime. Firms: ask about the MCP server on the call.
