Practice Finn: One AI Accountant for Your Whole Client Book (2026)

Most accounting software gives you a list of client files. You open one, work it, close it, open the next. The software has no view of your practice as a whole, so the job of knowing what needs you this week, across forty or eighty or two hundred clients, falls to you and a spreadsheet.

Practice Finn changes that. It is the practice-level tier of Finn, the AI accountant inside AccountsOS, and it talks to you about your entire client book before you have opened a single file.

What does "two-tier" actually mean?

Finn now works at two levels, and the level is set by whether you have a client selected.

At the practice level (your home screen, no single client in focus), Finn is about the whole portfolio. You ask it cross-client questions and it answers across every client at once. It surfaces the things that need you, named by client, and it can onboard new clients from the conversation.

At the client level (you have clicked into one client), Finn narrows to that company's books. This is the per-company Finn that already existed, made account-aware for practices: it treats you as a qualified peer, runs the bookkeeping in the background, and surfaces only what needs your judgement rather than walking you through basics.

The switch between the two is automatic. Selecting a client moves Finn from the practice view to that client. "Back to practice" returns it. There is no mode to toggle and remember.

What can I ask Finn about my whole book?

The practice level is built around the questions a practice owner actually asks on a Monday morning:

• "What needs me this week?"
• "Which clients have VAT due this month?"
• "Who's behind on reconciliation?"
• "Which month-ends are ready to close?"

AccountsOS already runs an attention engine for each company: it watches deadlines, reconciliation state, month-end readiness, missing statements and more. Practice Finn runs that engine across every client in your book, tags each item with the client it belongs to, and ranks them so the urgent things sit at the top.

So instead of opening every client file to find out where the pressure is, you ask once and Finn answers: "Acme — VAT due 4 July. Beta Trading — 12 transactions unreconciled. Gamma Studios — month-end ready to close." Every item names its client, and you can open any of them in a tap.

How do I move from the practice view into one client?

When you want to act on a specific client, you tell Finn: "open Acme", or you click the client in your dashboard. Finn switches focus to that client's books and hands you to the client-level agent for that company.

From there it is the full AccountsOS Finn: categorising transactions, running the reconciliation, preparing the month-end, drafting the VAT return, answering questions about that client's numbers. When you are done, "back to practice" returns you to the portfolio view where you started.

The point is that you never lose your place. The practice view is the cockpit; drilling into a client is a tap, and coming back is a tap.

Can I add or migrate a client without leaving the chat?

Yes. Onboarding a client is now part of the conversation, not a separate setup flow.

• "Add a client called Acme Ltd" creates a client company you manage, linked to your practice. The client does not need an account or to do anything; you run the books. Finn confirms the details with you before it creates anything.
• "Migrate my Xero client, Beta Trading" creates the company and opens the import so you can drop in the Xero, QuickBooks, Sage or CSV export. The AI reads the export, works out what it contains, and shows you a full preview before anything posts.

Both are write actions, so Finn proposes them in plain English and waits for your confirmation before doing anything. Nothing is created behind your back.

What happens on a brand-new practice with no clients?

This is where the two-tier model earns its keep at the very start. A new practice with zero clients used to land on a static dashboard with no guidance. Now Finn greets you and walks you into your first client: it offers to create a client you manage, migrate an existing book, or invite a client who wants their own access. Onboarding a practice is its first conversation with Finn, not a form.

Does my client need to use AccountsOS too?

No. For clients you manage, Finn creates the company under your practice and you keep the books on their behalf. The client does not need to log in, learn new software, or do anything. You feed receipts and statements (forward them, upload them, or connect a bank feed) and Finn does the rest.

If a client does want their own access, you can still invite them. The model supports both: practices that run everything, and practices whose clients are hands-on.

Does Finn keep me posted, or do I have to go looking?

Once a week Finn reports up. The practice digest aggregates what needs you across the whole book and lands in your Practice Finn thread and by email, loud items only, ranked and named by client. On a genuinely quiet week it stays silent rather than emailing you noise. It is the same proactive cadence the rest of AccountsOS uses, applied to the practice as a whole.

What does it cost?

Practice Finn is included in the AccountsOS practice plan, which covers unlimited clients under one flat fee rather than a per-client subscription. See the practice pricing page for the current numbers, and the migration guide if you are moving a book over.

Frequently asked questions

What is Practice Finn?

Practice Finn is the practice-level tier of the AccountsOS AI accountant. With no client selected it talks to you about your whole client book: what needs you across every client, your client list with a health line each, and adding or migrating clients from chat. Select a client and Finn narrows to that company's books.

How does Finn know what needs me across all my clients?

AccountsOS runs an attention engine per company, watching deadlines, reconciliation, month-end readiness and missing statements. Practice Finn runs that across every client in your book, tags each item with its client, and ranks them so the urgent things surface first.

How do I switch from the practice view into one client?

Say "open Acme" or click the client, and Finn switches focus to that client's books. "Back to practice" returns you to the portfolio view. The switch is automatic, set by which client is in focus, with no separate mode to toggle.

Can I add or migrate a client from the chat?

Yes. "Add a client called Acme Ltd" creates a client you manage. "Migrate my Xero client" creates the company and opens the import so you can drop in the export. Both ask you to confirm before anything is created.

Does my client need an account to use AccountsOS?

No. For clients you manage, Finn creates the company under your practice and you run the books. The client does not need to log in. You can still invite clients who want their own access.

Is Practice Finn included in the price?

Yes. It is part of the AccountsOS practice plan, which covers unlimited clients. See /for-accountants/pricing for the practice tier.
