Workflows worth examining

Prepare the work. Keep judgment human.

Agents can handle defined preparation steps while exceptions, decisions, and release stay with the people accountable for the work.

Workflow 01

Human reviewed

Document intake and triage

Sort incoming material against agreed rules, then send exceptions and routing decisions to a person for approval.

Workflow 02

Human reviewed

Extraction and validation

Prepare structured fields from documents, flag uncertainty, and hold every proposed value for human review.

Workflow 03

Human reviewed

Draft preparation

Assemble a first draft from approved sources so a qualified team member can check, revise, and release it.

Workflow 04

Human reviewed

Deadline and status monitoring

Watch agreed dates and states, surface exceptions, and let the responsible person decide the next action.

Workflow 05

Human reviewed

Internal knowledge retrieval

Find relevant internal material with source context while a team member verifies its use in the matter at hand.

Workflow 06

Human reviewed

Approved write-back

Prepare an update for an existing system and write it back only after the designated human approval gate.

Why custom

The workflow is the product.

The useful difference is not another place to chat. It is a supervised system designed around how work moves through the firm.

Workflow understandingA generic tool asks the team to adapt to it.The workflow is mapped before an agent is designed.
Current-tool integrationWork happens in a separate interface.The approved flow is planned around the firm’s current systems.
Human oversightOutput can look finished before it is checked.Review and approval are explicit workflow stages.
Measurable outcomesSuccess is reduced to prompts or usage.The audit defines process measures the firm can evaluate.

Designed for professional review

Different work. The same need for control.

Each discipline has its own inputs, risks, and judgment points. The workflow must respect those differences.

Close · intake · workpapers

Accounting

Prepare intake, extraction, workpaper drafts, and status updates while accountants retain every review and judgment call.

See workflow examples

Reporting · variance · exceptions

Finance

Organize reporting inputs, draft recurring commentary, and surface exceptions for the responsible finance team to assess.

See workflow examples

Matters · knowledge · first drafts

Legal

Support matter intake, internal knowledge retrieval, and draft preparation without replacing a lawyer’s review or advice.

How an engagement moves

Control is designed in, not added later.

The sequence establishes boundaries and review ownership before an agent reaches a live workflow.

  1. Stage 01

    Audit

    Map the current process, data boundaries, decision owners, approval gates, and a useful measure of the workflow.

  2. Stage 02

    Design and build

    Design the agent around real inputs and exceptions, then test prepared work with the people responsible for human review.

  3. Stage 03

    Integrate and deploy

    Connect only the agreed system boundaries, preserve the approval gate, and define escalation before release.

  4. Stage 04

    Optimize

    Monitor the agreed workflow, review exceptions with the team, and improve it without weakening professional oversight.

Before the first conversation

Questions firms ask first.

The useful answers depend on the workflow. These are the boundaries we establish before any build begins.

Is our accounting, finance, or legal firm a good fit?

A strong starting point is a repetitive, document-heavy workflow with a clear owner and a professional who can review the prepared work.

What happens during an AI Workflow Audit?

We map the current process, inputs, exceptions, system boundaries, review points, and the outcome your team wants to evaluate before proposing a build.

How do you protect client data and keep people in control?

The audit defines data access and handling boundaries for the specific workflow. Human review, approval, and escalation points are designed before deployment.

Can an agent work with the systems our firm already uses?

Integration depends on the system, available access, and the approved data boundary. We assess the current environment before committing to an integration path.

What does an engagement cost, and how long does it take?

Scope depends on the workflow, systems, and review requirements. The audit creates the basis for a defined proposal before development begins.
