Chapter One · The Core Practices

Three foundational engagements, defined by scope and measured by deliverable.

Every engagement begins with a fixed-fee scope letter and a tangible deliverable. These are the three practices that anchor the firm's work for established owner-operators.

  1. 01Tax Strategy

    Proactive, CPA-grade tax strategy built around your entity stack.

    Multi-entity tax planning for S-corps, C-corps, partnerships, and trusts — coordinated across federal and state returns, with year-round positioning rather than April reconciliation.

    Engagement model

    Fixed-fee annual retainer, quarterly tax projections

    Sample deliverables

    • Federal & state return preparation
    • Quarterly estimated-tax memos
    • Entity restructuring analysis
    • R&D credit and 199A strategy review

    Credentialed team

    12 licensed CPAs, 1 former IRS Senior Revenue Agent

  2. 02Fractional CFO & Accounting

    Partner-level financial leadership without a full-time executive seat.

    A senior advisor embedded in your finance function — owning the monthly close, KPI dashboards, cash forecasting, and lender/investor reporting, scaled to the rhythm of your business.

    Engagement model

    Monthly fractional retainer, 24-hour response guarantee

    Sample deliverables

    • Monthly close and management reporting
    • 13-week cash-flow forecast
    • Quarterly business-review dashboard
    • Board and lender presentation decks

    Credentialed team

    3 CFAs, 7 CPAs across the fractional practice

  3. 03Exit & Succession Planning

    A proprietary 7-step framework for owners thinking about the next decade.

    Built around the firm's Exit Readiness Framework, refined across 140+ successful business sales. We position the company, structure the entity stack, and run the diligence process with the operator's seatbelt still on.

    Engagement model

    Multi-year advisory, milestone-based fixed fees

    Sample deliverables

    • Exit Readiness Scorecard™
    • Tax-optimized transaction structure memo
    • Quality-of-earnings coordination
    • Post-close wealth and estate plan handoff

    Track record

    Clients averaging 2.3x EBITDA at close

Chapter Two · The Specialty Practices

For owners whose situation doesn't fit the generalist playbook.

Three dedicated engagements for real estate investors, healthcare practice owners, and founder-led SaaS companies — areas most firms handle by referral.

Specialty · Healthcare Practice Advisory

A dedicated advisory lane for physician- and dentist-owned practices preparing for sale, partnership transition, or multi-site expansion.

Built around the operational cadence of a clinical practice — payer-mix modeling, partner compensation waterfalls, ancillary revenue strategy, and pre-transaction normalization. The firm works with a small, named cohort of group practices across the Midwest and Mid-Atlantic.

Specialty · Cost Segregation & 1031

For real estate owners holding depreciable assets.

Cost segregation studies, 1031 exchange coordination, and deferred-exchange structures for investors holding commercial or multifamily assets. The firm partners with a third-party engineering firm on the physical study and owns the tax-side execution.

Specialty · M&A Readiness for Founder-Led SaaS

Positioning a software company for strategic or PE acquisition.

Pre-transaction financial hygiene for bootstrapped or lightly-funded SaaS operators thinking about a sale in the next 24 – 48 months. Recurring-revenue normalization, ARR audit, cap-table cleanup, and data-room preparation coordinated with your counsel.

A Letter from the Partners

The engagement model, written as it should be.

It is worth saying plainly: the most common anxiety we hear from a prospective client is not about competence. It is about the meter. A business owner has been burned, at some point, by a firm that quoted a $14,000 tax engagement and invoiced $41,000 — and the owner is not wrong to be cautious. That caution is the entire reason this firm runs on a different model.

Every engagement at GD Financial begins with a fixed-fee scope letter. We define the work in writing, we name the deliverable, and we commit to a price. If the scope changes, we re-write the letter — we do not run the clock. Across the last five years, we have delivered the quoted scope 99.2% of the time without a change order. The remaining 0.8% was a scope the client asked us to expand, not work we slipped in.

We do not pad hours. We do not delegate junior work without telling you. Every engagement has a named partner on the signature line and a 24-hour response guarantee on the client portal. When you call, a senior advisor picks up — or one calls you back the same business day.

This is not a marketing position. It is how a partnership behaves when it expects to keep clients for a generation. Our year-over-year retention rate, measured across the 2021 – 2024 fiscal periods, has held at 96%. The work is the work; the relationship is what we are actually being paid to maintain.
