Services
We offer bookkeeping services developed specifically for healthcare practices that require more than basic financial recordkeeping. Our process includes accurate tracking of patient copays, insurance reimbursements, and inventory management. Unlike general accounting methods, our system reflects the specific financial needs of medical offices. This focused approach helps minimize revenue loss and supports stronger financial performance. 
Nonprofit bookkeeping demands precise alignment of financial records with organizational mission objectives included. It is not merely accounting but a structured approach to stewardship and transparency compliance. Organizations must track incoming funds restrictions and the allocation of resources carefully with precision. GTB delivers specialized bookkeeping support to maintain audit readiness and grant compliance consistently assured. 
Audit Ready Bookkeeping supports medical and service businesses across Vancouver, WA and Portland, OR. We utilize the Smart Tax Clarity System to turn inconsistent records into disciplined weekly accuracy. All deductions are identified while IRS risk is reduced. Drawing on 75 years of experience, we deliver financial statements that are defensible and dependable. 
We examined financial records of a high-performing real estate agent who treated net commission deposits as revenue. A detailed review of six months revealed missing referral fees, unrecorded broker splits, and missing marketing receipts. This led to inaccurate tax reporting from underreported income and expenses. Proper bookkeeping clarifies commission ownership and compliance requirements.
We treat restricted and unrestricted funds as distinct categories within our nonprofit financial system. Each funding source is recorded according to donor-imposed conditions and timing requirements. This discipline reduces audit risk and ensures compliance with donor agreements. We consistently reconcile and report balances to maintain clarity and trust across all reporting periods required internally reviewed.
We track labor, materials, and overhead per project, so you know exactly which jobs are profitable and which are costing you money.
We provide a fully integrated bookkeeping plus tax solution that keeps financial operations consistent and audit ready throughout the year. Our Senior Tax Accountant oversees alignment between bookkeeping and tax preparation to reduce errors and improve efficiency. This unified system helps medical offices and service businesses capture deductions, avoid corrective fees. And maintain clear financial insight. 
Giesler-Tran Bookkeeping delivers specialized financial management for medical practices and service-based businesses. We go beyond basic bookkeeping through strategic services, including weekly reconciliations and audit-ready records that support ongoing decisions. Our tax-aligned approach helps prevent record issues and costly year-end adjustments. Clients may integrate tax preparation or work with their current accountants while receiving senior oversight and flat-rate pricing. 
Within the modern economic landscape, Small Business Financial Management provides the essential structure for business continuity and resilience. Owners contend with stricter funding requirements and unstable employment markets that heighten financial uncertainty. Many businesses still neglect financial oversight while focusing on product development, which can result in weakened cash flow performance. Strong financial systems create a safeguard around operations and ensure compliance and stability. 
Many small business owners assume that incoming money alone indicates strong financial health. However, hidden bookkeeping errors may reduce profitability, increase audit risk, and constrain growth potential. At GTB, we have seen cases ranging from disorganized receipts to flawed accounting records. Therefore, we prioritize early detection to ensure financial stability. 
Many product-based business owners mistakenly apply service-style bookkeeping practices. We emphasize that manufacturing and sales bookkeeping demands a different system. Service businesses primarily monitor cash in and cash out. Manufacturing introduces raw material variability, work-in-process tracking, and finished goods inventory. Our perspective centers on accurate financial reflection of production realities. 
Strategic bookkeeping provides business owners with clarity that replaces uncertainty and guesswork. At GTB, we repeatedly encounter three distinct roles: Technician, Manager, and Entrepreneur. The E-Myth describes how owners often become absorbed in day-to-day technical responsibilities. With organized financial data, owners can step confidently into management and ultimately return to entrepreneurial leadership.
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.
