Services

From cleanup to a finance function that runs.

Engagements are designed around the point of friction: unreliable books, an inconsistent close, limited financial visibility, or manual finance work that no longer scales.

01

Accounting Cleanup

Reconcile balance-sheet accounts, correct historical errors, clean the general ledger, resolve unsupported balances, and establish a reliable starting point for ongoing accounting.

02

Fractional Controller

Senior accounting leadership without the fixed cost of a full-time Controller: close oversight, technical accounting, controls, reporting, audit support, and finance-team direction.

03

Accounting OS & Monthly Close

Build a durable close architecture with reconciliations, schedules, review checkpoints, responsibility matrices, recurring workflows, and reporting deadlines.

04

Cash Flow & Management Reporting

Improve visibility through cash forecasting, management reporting, budget-to-actual analysis, KPI design, working-capital review, and decision-ready financial information.

05

Finance Automation & Data Engineering

Automate repeatable accounting workflows and connect fragmented financial data using Excel, Power Query, Python, SQL, cloud data tools, APIs, and AI-assisted processes—with accounting judgment and controls built in.

Approach

Stabilize. Standardize. Automate.

Automation is downstream of accounting quality. Sensei Advisors first establishes financial integrity, then builds a repeatable operating cadence, and only then automates the work that should be automated.

  1. 01

    Diagnose

    Identify close bottlenecks, unreliable balances, broken handoffs, duplicate work, and reporting gaps.

  2. 02

    Clean

    Reconcile accounts, correct the ledger, document assumptions, and establish a defensible financial baseline.

  3. 03

    Close

    Build the monthly accounting cadence: tasks, schedules, controls, owners, reviews, and deadlines.

  4. 04

    Forecast

    Convert accurate accounting into cash visibility, operating insights, variance analysis, and management reporting.

  5. 05

    Automate

    Use finance systems, data pipelines, rules, and AI to reduce repetitive work while preserving review and control.

Who we help

The gap between bookkeeping and a full finance department.

Founder-led businesses

You need reliable books, cash visibility, and senior accounting judgment—but not yet a full internal Controller organization.

Growing finance teams

Your accounting function works, but the close, controls, reporting, or systems need structure before the next stage of growth.

Complex environments

Multi-entity, inventory, manufacturing, regulated, technical-accounting, or system-heavy environments where generic bookkeeping is not enough.

Founder

Accounting judgment with a data-engineering layer.

JoMar Hester, MAcct, MSDS, brings more than two decades of accounting and finance experience, including Controller-level leadership, public accounting, operational accounting, financial reporting, controls, cost and inventory accounting, and finance-system implementation.

His work spans growing and regulated businesses where accounting must do more than record transactions: it must support operating decisions, withstand scrutiny, and scale. Sensei Advisors adds a modern technical layer to that foundation through data engineering, analytics, workflow automation, and AI-assisted finance processes.

The result is a practical operating model: repair what is unreliable, establish a disciplined close, improve management visibility, and automate only where automation strengthens the finance function.
