Our Services

Comprehensive Financial Services,
Strategically Delivered

Every engagement begins with understanding your goals. Whether you need precise tax compliance, day-to-day accounting support, or CFO-level strategic guidance, the scope is built around your situation rather than a package tier.

Tax Services

Tax Planning & Strategy

Proactive, year-round tax strategy for businesses and individuals. We identify opportunities to reduce liability, optimise timing, and align tax decisions with your broader financial goals — well before filing season closes the options off.

Entity optimisationMulti-state strategyEstimated payments
Discuss tax planning

Tax Preparation & Filing

Accurate, timely preparation of federal and state returns for individuals, partnerships, S-Corporations, C-Corporations, trusts, and nonprofits. Every return goes through a second-reviewer check for completeness and missed optimisation.

End-to-end payroll processing including tax deposits, filings, W-2s, 1099s, and compliance with federal and state requirements. We carry the complexity so your team's pay is simply never a thing you think about.

Business Advisory

Strategic guidance on growth decisions, profitability analysis, pricing, and compensation planning. We help you see the financial implications before you commit rather than explaining them afterwards.

Cash-Flow Planning

Forward-looking forecasting and budgeting that anticipates shortfalls, plans for investment, and holds stability through seasonal or growth-driven swings. Most businesses that fail are profitable on paper first.

Entity Structuring

Guidance on the right structure for your business — LLC, S-Corp, C-Corp, partnership — weighing tax treatment, liability protection, ownership goals, and the exit you may not be planning yet.

Client Outcomes

Measurable Results From
Strategic Engagement

These are real engagements, shared to illustrate what proactive tax strategy and financial advisory can deliver — as evidence of what is possible with the right approach, not as a guarantee of your result.

E-Commerce · Tax Strategy

Entity restructuring saved $187K over three years

Challenge

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

Approach

We restructured into an S-Corp with a management company, set defensible owner compensation, and built a multi-state filing strategy aligned to their actual nexus footprint.

Outcome

Effective tax rate reduced by 6.2 percentage points, projected savings of $187K over three years, and clean 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 and shrinking margins. The owners could not identify where the money was going and had no visibility into per-location profitability.

Approach

Fractional CFO engagement covering per-location P&L reporting, labour cost analysis, supply chain renegotiation, and a rolling 13-week cash-flow forecast.

Outcome

Margins moved from 12% to 21% within fourteen months. Owner distributions rose by $340K annually, and the practice opened a fourth location with the numbers to justify it.

Real Estate · Entity Structuring

$94K annual tax reduction through portfolio restructuring

Challenge

An investor with fourteen properties across three states held everything personally, creating excessive passive income exposure and no liability separation whatsoever.

Approach

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

Outcome

Annual tax reduction of roughly $94K, full liability separation across the portfolio, and a workable path to generational transfer and future 1031 exchanges.

Frequently Asked Questions

Common Questions, Clear Answers

A comprehensive range of accounting, tax, and advisory services: 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. These are available as standalone engagements or as an integrated package built around your needs.

Both. Roughly 65% of our clients are businesses — from startups through to mid-market companies — and 35% are high-income individuals and households. A great many of our business clients also engage us personally, which is genuinely useful: it lets us coordinate business and personal tax strategy as one picture rather than two.

Schedule through the form on this page or by calling the office. The initial conversation is a complimentary 30-minute discovery call with a CPA or senior advisor, where we discuss your situation, identify potential service fits, and answer your questions. If there is a mutual fit we send a detailed proposal within 48 hours. There is no obligation to proceed and no second call designed to close you.

Pricing depends on the scope and complexity of the engagement. Tax preparation is typically a fixed fee based on return complexity. Bookkeeping and payroll are monthly retainers. Advisory and CFO services are structured as monthly engagements with defined deliverables. You always receive a written proposal with specific pricing before any work begins — we do not bill hourly against an open-ended estimate.

Planning is a core part of the practice rather than an add-on. We prepare returns accurately and on time, but the planning work happens through the year — reviewing quarterly estimates, identifying deduction opportunities, modelling entity changes, and coordinating with your attorney and wealth advisor. By April most of the decisions that could have saved you money have already been made, which is precisely the problem with a filing-only relationship.

All client documents move through our encrypted portal, which uses 256-bit TLS and requires multi-factor authentication. You upload directly into organised folders, and we will never ask you to send sensitive information over unencrypted email — if you receive a request like that claiming to be from us, it is not. The portal also handles secure messaging and digital signatures for engagement letters and return authorisations.

Your initial consultation is with a CPA or senior advisor — Jonathan, Catherine, Marcus, or Danielle, depending on what you need. Day-to-day communication on an ongoing engagement is handled by your dedicated advisor with support from the operations team. You will always know who your primary contact is, and you will never be routed to an anonymous call centre.

Within one business hour for new enquiries during operating hours, Monday to Friday, 8:00 AM to 5:30 PM Mountain Time. For existing clients our target is same-business-day response on all messages. During tax season we extend availability and communicate proactively about timelines rather than leaving you to guess where your return is.

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