Services
Our bookkeeping service supports medical practices with financial management built around the unique requirements of healthcare. We monitor patient copays, insurance reimbursements, and inventory records instead of using a one-size-fits-all approach. Standard bookkeeping often misses these important details. Our specialized system helps safeguard your practice from preventable financial losses. 
Nonprofit bookkeeping integrates financial oversight with mission-driven responsibility and regulatory accountability requirements and standards. Bookkeeping extends beyond simple recordkeeping to ensure transparency, stewardship, and compliance at all times. Organizations must carefully document funding sources restrictions and proper utilization of resources included. GTB provides specialized bookkeeping support ensuring audit readiness and grant eligibility at all times. 
We offer Audit Ready Bookkeeping for medical and service businesses in Vancouver, WA and Portland, OR. Through our Smart Tax Clarity System, we replace end-of-year corrections with consistent weekly accuracy. Every deduction is captured, and IRS risk is reduced. With over 75 years of experience, we deliver defensible financial records, not merely acceptable ones. 
Real estate bookkeeping requires precise tracking of commissions, expenses, and compliance obligations. In one case, a high-performing agent believed net commission deposits represented total income. Our review of six months of data uncovered missing referral fees, broker splits, and unrecorded marketing expenses. This misalignment resulted in inaccurate tax reporting due to underreported income and expenses. Proper bookkeeping ensures each commission is correctly attributed and compliant with regulations.
Our nonprofit accounting approach prioritizes accurate separation of restricted and unrestricted funds from the outset. We document donor intent carefully and ensure each restriction is reflected in financial records. This prevents compliance issues and supports transparent reporting during audit processes. We also perform routine reconciliations to verify that all balances remain accurate without exception applied.
We track labor, materials, and overhead per project, so you know exactly which jobs are profitable and which are costing you money.
We deliver integrated bookkeeping and tax services designed to close the gap between disconnected financial providers. By combining ongoing bookkeeping with proactive tax strategy, our Senior Tax Accountant ensures accurate reporting and improved deduction capture. Medical offices and service businesses benefit from reduced CPA fix-it fees, fewer errors. And stronger year-round financial clarity and control. 
Our firm provides financial oversight for medical practices and service-based organizations, focusing on structured bookkeeping solutions. We extend bookkeeping through weekly reconciliations and audit-ready documentation to support informed financial decisions. Our tax-focused systems reduce risks from disorganized records and unexpected year-end corrections. Clients coordinate tax preparation or continue with existing accountants, supported by senior review and flat-rate billing. 
Small Business Financial Management serves as the foundation of stability in an increasingly volatile global economy. Business owners face tightening access to capital and unpredictable labor markets, which reduce tolerance for financial mistakes. Many entrepreneurs overlook their finances while prioritizing product development, allowing cash flow issues to grow unnoticed. Mastering bookkeeping through forecasting enables sustainable enterprise growth. 
Small business owners often assume revenue coming in means financial operations are secure. Unnoticed bookkeeping errors can erode profits, increase IRS audit exposure, and hinder growth. At GTB, we have seen issues from neglected receipts to disorganized accounting systems. We focus on early identification to preserve financial stability and performance. 
A recurring issue we see is product-based owners treating their accounting systems as though they operate service businesses. Manufacturing and sales bookkeeping, however, follows a more complex framework. While service firms record only cash inflows and outflows, manufacturing requires tracking raw material cost fluctuations, work-in-process, and finished goods inventory. We approach this with emphasis on financial accuracy. 
Strategic Bookkeeping: Growth and Stability
People
Brian Giesler
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 was one of Giesler-Tran Bookkeeping's early clients through my work with a school booster nonprofit. They cleaned up prior-year financials, cut unnecessary costs, and set us up with clear, reliable reporting we can actually use to make decisions. Brian brings deep experience and a strong support team (including senior tax accountant oversight). Highly recommend.

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.
