Services

Our service addresses the complexities of patient copays, insurance reimbursements, and inventory management with precision. We recognize that healthcare finances require specialized attention. By using a system designed for medical offices, we help prevent avoidable profit leaks. 
Nonprofit organizations must align financial management with mission objectives while maintaining strict accountability. Bookkeeping is not limited to reconciling accounts; it involves ensuring transparency, stewardship, and compliance with regulatory requirements. Every contribution must be tracked for source and restrictions as well as usage. GTB offers expert bookkeeping services that maintain audit readiness and grant eligibility at all times. 
Audit Ready Bookkeeping is provided by us for medical and service businesses located in Vancouver, WA and Portland, OR. We apply the Smart Tax Clarity System to replace year end uncertainty with steady weekly accuracy. We capture all deductions while lowering IRS exposure. Our 75 plus years of experience ensure defensible, reliable financial reporting. 
In real estate operations, bookkeeping plays a vital role in financial clarity. We worked with an agent who misinterpreted net commission deposits as full earnings. Six months of records showed missing referral fees, broker splits, and untracked marketing expenses. As a result, tax reporting was inaccurate due to underreported income and expenses. Bookkeeping discipline ensures proper commission allocation and regulatory compliance.
We manage nonprofit finances by strictly distinguishing restricted funds from unrestricted operating resources. Each donation is classified according to donor intent at the time of receipt. This prevents misuse, reporting inconsistencies, and potential compliance violations during audits. We maintain detailed schedules and monthly reconciliations to ensure accuracy and transparency at all required reporting times completely.

Sound Small Business Financial Management is critical to sustaining growth within volatile markets and tightening economic conditions. Business owners face increased borrowing constraints and shifting workforce dynamics that elevate operational risk. However financial planning is often overlooked in favor of immediate product goals, allowing cash flow issues to persist. Robust financial discipline builds a protective structure around business efforts and supports long-term viability. 
Small business owners often assume that steady revenue inflows mean everything is under control. However, unnoticed bookkeeping errors can silently erode profits, trigger IRS scrutiny, and restrict expansion. GTB has experienced a wide variety of issues, from messy receipts to disorganized financial files. We focus on early identification to maintain financial stability and growth. 
Recently, we have observed a growing trend where product-based business owners manage their financials as if they were service providers. However, manufacturing and sales bookkeeping requires a fundamentally different approach. Service businesses typically track only money coming in and going out. In contrast, manufacturing involves raw material cost fluctuations, work-in-process, and finished goods inventory management. 
Strategic bookkeeping separates operating a business on guesswork from operating with financial clarity. At GTB, we see three roles in business owners: Technician, Manager, Entrepreneur. The E-Myth explains how owners often remain stuck in daily technical work. With clean financials, owners can move into the Manager role and regain Entrepreneur focus. People

Owner / Founder
Im a communicator.
A talker.
An entertainer.
Most people who know me know I usually have plenty to say.
But when Im in the presence of the team I hand-picked the bookkeepers, the senior tax accountant, the specialists, and the people trusted to do the work they were hired to do I love to sit back and listen.
In client meetings, that is one of my favorite moments.
A client starts explaining what feels confusing.
A bookkeeper asks the question that matters.
A tax professional catches the detail that could have been missed.
The team starts connecting the dots.
And I get quiet.
Not because I have nothing to say.
Because sometimes leadership is knowing when to stop talking and let the right people do what they do best.
Life has taught me that.
There is power in stepping back.
There is wisdom in listening.
And there is something incredible about watching capable people bring clarity.

I own a series of small, different themed eateries and use Brian for all of them. He does the research for me and makes sure everything runs smoothly. There were many things that I had never even considered that he knew about, and it saved me a bunch of money, and more importantly, headaches. Wish I had found him sooner.
