§7216-sensitive practices

ENTRY CPA-0001

Get through busy season with AI capacity — client data stays under your firm's control.

Cartulary gives CPA teams a private control layer for client intake, workpaper prep, and CAS responses. Your firm's permissions, review gates, and audit trail sit between staff workflows and every model request.

Workflow 01

Client document intake and organization

Route portal uploads, emails, and prior-year files into a client-specific evidence map before a preparer starts sorting.

Workflow 02

Workpaper prep and tie-outs with review gates

Draft workpaper notes and tie-out suggestions only after source fields are linked, masked where needed, and queued for reviewer sign-off.

Workflow 03

Client query responses in CAS

Prepare response drafts from approved client context, then require a human release step before anything leaves the firm.

Busy-season workflow walkthrough

REVIEW QUEUE

Start with one packet-heavy workflow: document intake through a reviewed workpaper note. The control layer records who used which source, what was masked, and where reviewer judgment entered.

  1. Client packet lands. W-2s, K-1s, bank exports, and prior-year workpapers are assigned to the client record.
  2. Policy checks run first. Sensitive fields are masked or blocked according to the firm's written AI use policy.
  3. Preparers get a draft map. The system suggests document categories, missing items, and tie-out candidates with source links.
  4. Reviewer gate stays mandatory. A senior reviewer approves, edits, or denies each suggested workpaper note before use.
  5. Every step is reversible. A partner can revoke a response draft, restore the prior note, and keep the reason on the record.

Compliance language

Designed for §7216-sensitive practices; client data use under your firm's written policies.

Cartulary is designed to support CPA teams that need policy control before client data is used in AI workflows. Reviewer sign-off gates stay in the path, and drafts can be reversed before client delivery.

Operating record

Policies matter because they can be enforced.

Each workflow ties approved use, denied use, masked fields, and reviewer decisions back to a record your firm can inspect when a client, partner, or regulator asks what happened.

04

Founder-led credibility note

NO BLACK BOX

Cartulary is founder-led and built for firms where a partner remains accountable for client work. The product bias is control first: narrow workflows, written policies, reviewer judgment, and a durable record of every AI-assisted action.

05

Scope the first busy-season workflow.

20 MINUTES

Bring one intake, workpaper, or CAS response workflow. Leave with the control points that need to exist before staff use AI on client work.

06

The CPA Firm AI Use Policy Template

POLICY TEMPLATE

A practical fallback for firms still setting internal rules: permitted uses, restricted data, review duties, vendor questions, and a partner sign-off page.

Template offer · cpa-firm-ai-use-policy-template · form posts to /api/lead

The template is for firms evaluating policy and enforcement.

FAQ
What does this cost?

The working session scopes a narrow workflow and the control requirements before a proposal. The business case should tie to seasonal overtime, rework, partner review time, and risk reduction.

Is there enough time before busy season?

Yes, if the first rollout is narrow. Start with document intake, workpaper tie-outs, or CAS response drafts rather than a firm-wide transformation.

Will client data train vendor models?

The control layer is designed around firm-owned policy, model routing, masking, and audit logs. Where contractually supported, client data is not retained for vendor training.

Does this replace preparers or reviewers?

No. It gives staff draft structure and source-linked suggestions while keeping reviewer sign-off, partner release, and reversibility in the workflow.
