core value proposition

Built on Trust. Evolved Through Innovation.

PBTSI was founded on the belief that businesses deserve better accounting support — proactive, transparent, and relationship-driven. What began as a traditional Las Vegas accounting firm has evolved into a fully remote, technology-enabled financial partner. While our tools have advanced, our core values remain the same: integrity, commitment, and continuous improvement. Through thoughtful client assessments and a cross-trained team spanning bookkeeping, payroll, CFO advisory, and tax, we deliver strategic guidance with zero surprises — operating as true partners, not vendors.

testimonials

Trusted by Business Owners for 24 Years

I am grateful to have the opportunity to work with Stephanie White and her team at PBTSI. For years Stephanie has given me the needed guidance to thrive as a young and ambitious business owner in the Las Vegas Valley. Not only has she helped with my accounting for my business but she has also helped me with starting my Non-Profit. She has helped me create a business AND a Non-Profit step by step. I would recommend her services to anyone who asks about accounting. It is safe to say I will continue to be working with Stephanie and her team!

Aniciete Training Club

PBTSI rescued my company and me from the jaws of defeat. We had neglected our accounting department to the point that we hadn’t received month-end financials for 6 months. We didn’t know how to whip the department into shape because we’re mental health professionals, not accountants. We reached out to PBTSI while on the verge of bankruptcy, described the situation to them, and looked at them like deer in headlights hoping they could fix everything. It’s taken time and effort on our part, but 9 months later, we’re receiving on-time, accurate monthly financials, and we’ve completely revamped our accounting practices. We’re implementing budgets and financial meetings across departments, all under the leadership of PBTSI. PBTSI spoke in plain language and kept the jargon out. They walked me through QuickBooks personally and professionally. They helped me understand my financials and that I can reconfigure them in ways that make sense to me. They worked closely with staff in my business to undo confusing policies and procedures and implement streamlined systems. They worked closely with my CPA to ensure they have everything they need without making me feel like a go-between with my accountant and CPA. PBTSI is on my team. They’re kind, professional, knowledgeable, and experienced. I can’t emphasize how nice it is to have an accounting team that speaks English to me instead of accounting-ese. I have recommended PBTSI to anyone who asks me about accounting.
