Beyond CAS and CAAS: Why Finance-as-a-Service Is the Complete Solution
By TED ROSE, ROSE FINANCIAL SOLUTIONS
In 1994, I founded ROSE to provide small to midsized companies with accrual-based accounting and financial operations support—a concept that was virtually unheard of at the time.
In 1995, I even coined the term “accounting outsourcing” in the Washington Business Journal. But as our clients grew, we quickly realized that providing historical financial information alone wasn’t enough. Growing companies didn’t just need to know what happened—they needed help understanding what’s next.
That’s why I had named the company Rose Financial, not Rose Accounting. From the beginning, I knew finance—not accounting—was the end goal.
By 2009, we signed what I consider to be our first Finance-as-a-Service (FaaS) agreement with Blackboard, embedding technology directly into our solution. By 2020, every ROSE client engagement included technology as a core component, and we had fully shifted to the FaaS model.
Meanwhile, the accounting profession was evolving too. The first DCPA conference in 2012 marked a turning point for the industry, accelerating the growth of Client Accounting Services (CAS) and Client Accounting and Advisory Services (CAAS). These have become the fastest-growing service lines for CPA firms over the past few years—and for good reason. They represent the profession’s recognition that clients want more than compliance—they want guidance and support.
But not all solutions are equal.
Many CAS and CAAS models rely on labor arbitrage—offshoring tasks to cut costs. ROSE took a different approach. Our version of FaaS focuses on automation and integration, not cheap labor. We invest in upskilling and developing professionals who can serve as trusted guides for our clients—leaders who help entrepreneurs and business leaders through their entire lifecycle, from startup to exit.
We’ve helped build unicorns and guided hundreds of founders through the complex journey of growth, scale, and success.
And now, with technology finally catching up to our vision, we’re seeing the profession embrace what we’ve known all along—finance is the future.
The Limits of CAS and CAAS
CAS focuses on delivering the fundamentals—bookkeeping, reconciliations, payroll, and reporting. CAAS adds a layer of insight—helping clients interpret the data and offering strategic advice.
But as Hitendra R. Patil describes in his CAAS-Chasm framework, many firms get stuck in the gap between providing advice and helping clients execute.
The challenge isn’t the intent—it’s integration. Advisory has limited impact if it isn’t connected to the systems, people, and processes that bring it to life.
FaaS: Starting With the End in Mind
Finance-as-a-Service (FaaS) closes that gap. Instead of dividing work between accounting and advisory, FaaS starts with the business outcome and builds the complete financial infrastructure to deliver it.
FaaS unites the best of CAS and CAAS into one integrated, scalable model that combines:
People – Skilled finance professionals who guide, not just record.
Process – Streamlined workflows built on automation and best practices.
Technology – Enterprise-grade, AI-enabled systems that deliver real-time insights.
Organization – Integrated teams aligned with client goals.
Data – A single source of truth for clarity, accuracy, and strategic decision-making.
This approach ensures that insights become actions and that financial operations drive measurable results.
The Next Evolution of Finance
The accounting profession has made tremendous progress in moving from compliance to advisory—but FaaS goes further. It provides the full financial solution modern companies need to bridge strategy and execution.
Whether it’s supporting startups or scaling established enterprises, FaaS delivers end-to-end visibility, accountability, and agility.
This is a third option —beyond tax and audit—that the profession has been waiting for. And now that technology, automation, and AI are maturing, the opportunity has never been greater.
At ROSE, we’ve been doing this longer than anyone—and we’re just getting started.
💡 The takeaway: CAS and CAAS are important steps in the profession’s evolution. But FaaS starts with the end in mind—bringing together people, process, technology, organization, and data to deliver complete, scalable financial clarity.
