Otto asks for what is missing, reminds clients and writes the invoice reminder. The work stays yours. You say yes before anything goes out.

Sample business and sample data. Not a customer. This owner has let Otto handle some things alone. By default he asks first.

Four jobs off your plate.
Built around a firm's year.

The tax work and the advice stay yours. Otto does the asking, the reminding and the setting up, every month, busy season included.

Waiting on the client, again

Document requests that chase themselves.

Each client gets a checklist of what you need. When something is missing, Otto writes a reminder, and when it is uploaded he ticks it off. Everything lands on one record.

No. 1Getting documents from clients ranked as accounting firms' biggest workflow problem.Financial Cents, State of Accounting Workflow Automation 2025, 816 firm owners. A vendor survey.

Work started before the letter came back

Engagement letters signed before work starts.

Letters go out from your template and clients sign on their phone. The signed copy is saved on the client, and the invoice waits until it is signed. The IRS e-file authorization stays its own form.

About 55%of tax claims against CPAs involved no engagement letter for that service.AICPA Professional Liability Insurance Program data, 2024, as reported by NJCPA, Jan 20, 2026.

Setting up the same tasks every month

Monthly work that repeats itself.

Bookkeeping, payroll, sales tax and extensions become tasks that come back on their own, with a due date and an owner. Nothing depends on someone remembering.

Each recurring task comes back on its own date, with its owner and its checklist.

Invoices that ride through busy season

Invoices and polite reminders.

Invoices with card or bank payment, and a reminder that waits for your OK when one runs late. Payments post to QuickBooks.

What Otto never does in your firm.

The tax work and the advice stay with your firm. Otto books, requests, reminds and writes, and you set the rest.

  • He never gives tax advice. No opinions on a client's position and no promises about outcomes.

  • You choose what goes in. Names, documents requested and invoices. What tax-return data goes in is your firm's call.

  • E-sign is not the 8879. Engagement letters are signed here. The IRS e-file authorization is a separate form.

  • He never works in the dark. Every message and change is logged. Changes and bookings undo with one tap; a sent email can't be unsent.

Accounting firm questions.

Plain answers. If yours is not here, ask through Get started and a person replies.

Does it replace TaxDome or Karbon?

For many small firms, client intake, document requests, signatures, recurring tasks, invoices and email are covered here. If you rely on a tax organizer, workpaper review or a deep client portal, ask us first. We will tell you straight.

Is client tax data safe to put in?

You choose what goes in. We give you a security summary for your written information security plan. Using outside tools with tax-return information needs client consent under section 7216, so decide that with your own advisers.

Will Otto give tax advice?

No. He books, requests, reminds and writes. Anything about a client's tax position is yours.

Can Otto send the 8879?

No. Engagement letters are signed here, and the IRS e-file authorization stays in your tax software.

Will clients know it is AI?

Yes. Ask and Otto says he is an AI assistant, and a person is one request away.
