The Advisory Difference

Compliance Keeps You Compliant.
Advisory Keeps You Competitive.

Most accounting firms stop at filing your returns and balancing your books. We start there — and then build forward. The difference isn't incremental. It's structural.

  • Monthly bookkeeping and reconciliation
  • Basic financial statements

  • Reactive — you ask, they respond
  • Historical view — looking backward

Measurable Results From
Strategic Engagement

These outcomes represent real engagements. We share them to illustrate the kind of impact that proactive tax strategy and financial advisory can deliver — not as guarantees, but as evidence of what's possible with the right approach.

E-Commerce · Tax Strategy

Entity Restructuring Saved $187K Over Three Years

Challenge

A seven-figure DTC brand was operating as a single LLC, creating significant self-employment tax exposure and limiting loss utilization as they scaled into new product lines.

Approach

We restructured into an S-Corp with a management company, optimized owner compensation, and established a multi-state filing strategy aligned with their nexus footprint.

Outcome

Reduced effective tax rate by 6.2 percentage points. Projected savings of $187K over three years. Cleaner financials that supported a successful line of credit application.

Medical Practice · CFO Advisory

Operating Margins Improved From 12% to 21%

Challenge

A three-location dental practice had growing revenue but shrinking margins. The owners couldn't identify where the money was going and had no visibility into per-location profitability.

Approach

We implemented fractional CFO services including per-location P&L reporting, labor cost analysis, supply chain optimization, and a rolling 13-week cash-flow forecast.

Outcome

Margins improved from 12% to 21% within 14 months. Owner distributions increased by $340K annually. Practice added a fourth location with confidence.

Explore CFO Services
Real Estate · Entity Structuring

$94K Annual Tax Reduction Through Portfolio Restructuring

Challenge

A real estate investor with 14 properties across three states held everything in their personal name, creating excessive passive income exposure and no liability separation.

Approach

We designed a holding-company structure with individual LLCs per property, implemented cost-segregation studies on qualifying properties, and coordinated with their estate attorney.

Outcome

Annual tax reduction of approximately $94K. Full liability separation across the portfolio. Clearer path to generational wealth transfer and future 1031 exchanges.

Client Perspectives

What Our Clients Say

"We came to Whitfield for tax preparation and left with a complete financial strategy. Jonathan identified an S-Corp election that saved us over $40K in the first year alone. The proactive approach is what sets them apart — they think about next year before this year is even filed."
Michael Russo
Owner, Russo Building Solutions — Contractor
"As a physician, I needed someone who understood both the tax complexities of a medical practice and the personal financial planning that goes with it. Catherine and her team delivered both. My only regret is not finding them five years sooner."
Dr. Sarah Patel
Owner, Summit Orthopedics — Medical
"We had a messy multi-state situation with our e-commerce business that two previous firms couldn't sort out. Whitfield not only cleaned it up — they restructured our entire approach. The portal is excellent, communication is fast, and I finally feel like someone is actually watching out for us."
Jessica Lin
Co-Founder, Canopy Brands — E-Commerce
"The fractional CFO service has been transformational for our agency. Before Whitfield, we were guessing at profitability per client. Now we have real data, real forecasts, and a real plan. Our cash position has never been stronger."
David Martinez
CEO, Brightline Agency — Professional Services
"My husband and I are both W-2 employees with rental properties and investments. We needed someone who could handle the complexity without making us feel stupid for asking questions. Danielle has been incredible — patient, thorough, and always one step ahead."

Frequently Asked Questions

Common Questions, Clear Answers

We provide a comprehensive range of accounting, tax, and advisory services including: tax planning and strategy, tax preparation and filing for individuals and businesses, bookkeeping and reconciliation, payroll administration, CFO and fractional CFO services, business advisory, financial reporting, cash-flow planning, entity structuring, and tax resolution. Services are available as standalone engagements or as integrated packages tailored to your needs.

Both. Approximately 65% of our clients are businesses — from startups to mid-market companies — and 35% are high-income individuals and households. Many of our business clients also engage us for personal tax planning and preparation, which allows us to coordinate business and personal tax strategy holistically.

You can schedule a consultation through our website form or by calling our office. The initial conversation is a complimentary 30-minute discovery call with a CPA or senior advisor. We'll discuss your situation, identify potential service fits, and answer your questions. If there's a mutual fit, we'll send a detailed proposal within 48 hours. There's no obligation to proceed.

Pricing depends on the scope and complexity of your engagement. Tax preparation is typically quoted as a fixed fee based on return complexity. Bookkeeping and payroll are quoted as monthly retainers. Advisory and CFO services are structured as monthly engagements with clear deliverables. You'll always receive a written proposal with specific pricing before any work begins — no hourly surprises.

Tax planning is a core part of our practice. While we do provide accurate and timely tax preparation, our planning work happens throughout the year — not just in March and April. We review quarterly estimates, identify deduction opportunities, model entity changes, and coordinate with your other advisors to minimize your overall tax burden. This proactive approach is what most of our advisory clients value most.

All client documents are exchanged through our encrypted client portal, which uses 256-bit TLS encryption and requires multi-factor authentication. You upload documents directly to organized folders, and we never request sensitive information via unencrypted email. The portal also supports secure messaging and digital signatures for engagement letters and tax return authorizations.

Your initial consultation will be with a CPA or senior advisor — Jonathan, Catherine, Marcus, or Danielle depending on your service need. Day-to-day communication for ongoing engagements is handled by your dedicated advisor with support from our operations team. You'll always know who your primary contact is, and you'll never be passed to an anonymous call center.

We respond to all new inquiries within one business hour during operating hours (Monday – Friday, 8:00 AM – 5:30 PM MT). For existing clients, our target is same-business-day response on all messages. During tax season, we extend our availability and communicate proactively about timelines. Our Financial Assistant is also available 24/7 for basic questions and consultation scheduling.

Within one business hour, a CPA or senior advisor will contact you by phone or email to schedule your 30-minute discovery conversation. During that call, we'll discuss your needs, answer your questions, and outline sensible next steps. If you decide to proceed, we'll confirm scope, deliverables, and timing before any billable work begins — and you'll receive a written proposal when appropriate.
