Google Gemini is Google's AI model, available as a standalone assistant and integrated into Google Workspace as Gemini for Workspace. For UK accounting firms using Google Workspace (Gmail, Docs, Sheets, Drive, Meet), Gemini offers an AI layer directly within the tools the practice already uses. For practices on Microsoft 365, Copilot is the closer equivalent.

This guide covers how Gemini works for accounting tasks, the data protection requirements for professional use, and how it compares to ChatGPT and Claude for accounting-specific work.

Gemini versions and what they cover

Gemini (standalone)

The standalone Gemini assistant at gemini.google.com operates similarly to ChatGPT.com — you type a prompt and receive a response. The standard Gemini 1.5 Flash model is available free; Gemini Advanced (using Gemini Ultra) is available on a paid subscription.

Data protection position: standard Gemini usage on consumer accounts may use interactions to improve Google's models. This makes consumer-tier Gemini unsuitable for identifiable client data, following the same logic as ChatGPT Free.

Gemini for Workspace

Gemini for Workspace integrates AI features directly into Google Workspace apps:

  • Gmail: draft email replies and summaries based on the email thread; summarise long email chains
  • Google Docs: draft documents from prompts; rewrite, summarise, or expand existing content
  • Google Sheets: analyse data and explain formulas; suggest functions; create visualisations
  • Google Meet: generate meeting summaries and action items after calls
  • Google Drive: search across documents using natural language queries

Gemini for Workspace is available as an add-on to Google Workspace Business and Enterprise plans. The business-tier data protection terms are significantly stronger than the consumer tier — interactions in Workspace are not used to train Google's AI models, and data remains within the customer's Workspace environment.

Data protection for Gemini for Workspace

For UK accounting practices using Google Workspace:

  • Gemini for Workspace Business and Enterprise add-ons are covered by Google's Workspace Data Processing Amendment, which is UK GDPR-compliant
  • Data is processed within the customer's Google Workspace environment
  • Google does not use Workspace customer data to train its AI models under the business-tier terms
  • Data residency can be configured to EU regions for Google Workspace Enterprise Plus, which may satisfy UK data residency preferences

Verify current data residency options with Google, as these continue to develop.

What Gemini does well for accounting work

Gmail integration

For practices on Google Workspace, Gemini's Gmail integration is the most immediately useful feature. It can:

  • Draft a full reply to a client email based on a brief instruction ("Draft a reply confirming receipt of their documents and requesting their pension contribution details")
  • Summarise a long email thread into key points before you respond
  • Suggest a response when you have a draft open and click the AI drafting option

The Gmail integration removes the friction of switching to a separate AI tool — the drafting happens within the email interface. Review the draft, adjust for tone and accuracy, then send.

Google Docs

For document drafting in Google Docs, Gemini can produce first drafts from prompts inserted directly into the document. The workflow is similar to using ChatGPT in Word, but without switching applications. Useful for:

  • First drafts of advisory reports or client proposals
  • Management accounts commentary based on figures you type into the document
  • Engagement letter sections or standard clauses

Google Sheets

Gemini in Sheets is useful for accountants who build models and analyses in Sheets. It can explain complex formulas, suggest appropriate functions for a task, and create basic charts from data. It is not a reliable calculator for tax computations, but for building analytical templates and understanding Sheets functionality, it is genuinely helpful.

Google Meet summaries

Gemini generates meeting summaries and action lists from Google Meet calls, similar to Microsoft Copilot in Teams. This is useful for client calls conducted via Google Meet. The same consent requirement applies: inform clients before recording and summarising.

Comparing Gemini to ChatGPT and Copilot

Gemini vs ChatGPT: for practices on Google Workspace, Gemini for Workspace has the integration advantage — drafting happens within Gmail and Docs rather than in a separate tool. Output quality for accounting correspondence is broadly comparable, though ChatGPT is generally rated more highly for complex document quality and precise instruction following. ChatGPT has a larger user community and more publicly available prompts.

Gemini vs Copilot: Gemini for Workspace and Microsoft 365 Copilot are direct equivalents — each integrates AI into their respective productivity suite. If your practice uses Google Workspace, Gemini is the natural choice. If you use Microsoft 365, Copilot is. Both offer business-tier data protection appropriate for client work. Switching productivity suites to access a different AI assistant is not warranted.

Gemini in Sheets vs Copilot in Excel: both offer AI assistance for spreadsheet work. For practices doing complex financial modelling in Sheets, Gemini's ability to explain and suggest formulas is useful. For Excel-heavy practices, Copilot in Excel offers similar functionality.

Setting up Gemini for an accounting practice

  1. Confirm your Google Workspace plan includes or can add Gemini for Workspace (Business or Enterprise add-on)
  2. Enable Gemini for Workspace in the Google Admin console for your domain
  3. Verify data processing terms under your Workspace agreement cover Gemini features
  4. Brief staff on which tier is in use and the data protection position
  5. Establish prompting guidelines and review requirements for AI-generated output
  6. Create a shared library of tested prompts for common tasks

The setup process is simpler than deploying a standalone AI tool, because Gemini for Workspace operates within the Google infrastructure your practice already manages.

Limitations for accounting use

Not a tax calculator: Gemini, like all AI language models, is not a reliable arithmetic tool. Do not use it for tax computations.

Training data cutoff: Gemini's knowledge has a cutoff date. It may not reflect current UK tax rates, recent Budget changes, or the latest HMRC guidance. Always verify specific figures and legislative references against HMRC's current website.

UK-specific accuracy: Gemini may default to international or US conventions for tax and accounting matters. Check that advice is UK-specific before using it in client work.

Integration with accounting software: Gemini does not integrate with Xero, QuickBooks, Sage, or Iris directly. It operates within the Google Workspace environment, which is separate from most accounting software. This limits its usefulness for workflows that need to interact with accounting system data.

Key takeaways

  • Gemini for Workspace (Business or Enterprise add-on) is the appropriate tier for UK accounting practices — consumer-tier Gemini should not be used with identifiable client data.
  • For Google Workspace practices, Gemini's integration within Gmail, Docs, Sheets, and Meet is its primary advantage — AI assistance without switching applications.
  • Output quality for accounting correspondence is broadly comparable to ChatGPT and Copilot; choose based on your productivity suite rather than AI capability differences.
  • Gemini is not a reliable tax calculator and may not reflect current UK figures — verify all specific claims against HMRC primary sources before using in client work.
  • Apply the same review requirements to Gemini output as to any AI tool: check accuracy, UK-specificity, tone, and professional compliance before use.

Frequently asked questions

Is Gemini for Workspace GDPR-compliant for accounting client data?

Gemini for Workspace Business and Enterprise add-ons are covered by Google's Workspace Data Processing Amendment, which is UK GDPR-compliant. Data processed by Gemini in the Workspace context is not used to train Google's AI models under business-tier terms. Verify the current data residency options available in your Workspace plan and confirm the Data Processing Amendment covers your use of Gemini features specifically.

Does Gemini work offline?

No. Gemini for Workspace is a cloud-based service and requires an internet connection. If your practice has internet connectivity issues, this limits Gemini's reliability as a tool. All AI writing tools currently available are cloud-based.

Can Gemini in Sheets replace a financial model built by an accountant?

No. Gemini can assist with formula construction, data summarisation, and explaining Sheets functionality. It cannot build the analytical judgement, accounting knowledge, or professional insight that go into a properly structured financial model. It is a tool to support the accountant building the model, not a replacement for the accountant.

Add a standard note to your meeting invitations stating that the call may be recorded and summarised using AI tools for the purpose of producing meeting notes. At the start of the call, confirm consent verbally. If a client does not consent, do not record or summarise the call using AI. Store the consent record in your client file.

Should my practice switch from Microsoft 365 to Google Workspace to access Gemini?

No. Copilot in Microsoft 365 provides equivalent AI integration for M365 practices. The productivity suite you use should be driven by your practice's operational requirements, not by AI feature differences that are broadly comparable between the two platforms. If your practice is already well-established on Microsoft 365, the disruption cost of switching exceeds any AI-related benefit.
