The “A” in CAS from Accounting to Advisory: 2025 Insights and 2026 Priorities

Themes emerging from Digital CPA 2025 and year-round conversations with CAS leaders, shared by Christine Triantos, Co-Founder of Infinite Advisors, and Deneen Dias, Co-Founder of Infinite Ties.

The Big Reality: CAS Teams Are Drowning

After Digital CPA 2025, one theme was undeniable: there is no shortage of work.

CAS leaders are reporting full pipelines, waitlists for services, and more opportunity than capacity. Yet in the same breath, they’re saying:

  • “We need clearer CAS deliverables.”
  • “Our team is great at reporting—but struggles with advisory.”
  • “We’re overwhelmed by AI and technology.”
  • “We don’t know how to standardize advisory.”

Fifteen years ago, CAS stood for Client Accounting Services. It meant back-office support—reconciliations, bill pay, financial statements.

Then it evolved into Client Accounting and Advisory Services.

Today? The firms we’re speaking with say it plainly:

CAS now stands for Client Advisory Services.

And that shift is where both the opportunity—and the friction—lives.

From Reporting to Storytelling: The Advisory Gap

CAS talent is excellent at:

  • Preparing financial statements
  • Closing the books accurately
  • Delivering precise reporting

But advisory requires something different.

Controllers and CFOs don’t just present reports. They:

  • Interpret trends
  • Model scenarios
  • Recommend actions
  • Tell stories with the data

Clients aren’t asking, “Is my balance sheet accurate?”
They’re asking, “What do I do next?”

And that’s the gap firms are working to close.

AI Overload: Automation Is Not Advisory

AI dominated the 2025 conversation. But most firms are still asking:

  • Which AI tools should we use?
  • How do we automate transaction work?
  • How do we use AI to support advisory—not replace it?

Technology in CAS falls into two major buckets:

1. Automation of Routine Work

2. Advisory Enablement & Insight Generation

For example, many firms are using A2X to automate ecommerce accounting workflows—eliminating manual reconciliation between platforms like Shopify or Amazon and the general ledger. That automation creates capacity.

On the expense and AP side, tools like Ramp streamline spend management, automate coding, improve approval workflows, and provide real-time visibility into cash flow trends—giving CAS teams better data faster and reducing manual friction.

And for reporting, visualization tools like Reach Reporting help transform financial data into client-ready dashboards that support advisory conversations rather than static PDF packets.

But here’s the key insight from 2025:

Automation alone does not create advisory.
It creates space for advisory.

Firms that succeed in 2026 will let technology carry the routine—so people can carry the conversation.

Clients Are More Savvy Than Ever

Another strong theme: clients are more informed.

They know:

  • AI exists.
  • Automation exists.
  • Repetitive work should be faster.
  • Their accountant should be proactive.

Clients are no longer impressed by a financial packet. They want:

  • Cash flow forecasting conversations
  • Scenario modeling
  • KPI strategy
  • Proactive guidance before problems occur

Think of the Ritz-Carlton analogy. The Ritz doesn’t just respond to requests—they anticipate needs.

Advisory works the same way.

And that level of service commands premium pricing.

The Soft Skills Revolution

Perhaps the most important 2025 insight: technical excellence is no longer enough.

CAS leaders are investing in:

  • Storytelling training
  • Client communication coaching
  • Role-playing advisory conversations
  • Meeting facilitation skills
  • Confidence building for talent

Many accounting professionals were trained to:

  • Be precise
  • Be reserved
  • Stay in the numbers

But advisory requires:

  • Authenticity
  • Curiosity
  • Business acumen
  • Strategic thinking

Role-playing—while uncomfortable—is proving powerful. When teams practice:

  • Explaining a cash dip
  • Presenting two strategic options
  • Justifying pricing adjustments

…they build confidence and advisory fluency.

And yes—AI can help here too. Firms are experimenting with using AI as a feedback tool on meeting transcripts to identify missed opportunities or pricing hesitations.

But the message is clear:

Use AI. Don’t lose the human.

The Staffing Model Shift

Talent remains a constraint—but it’s evolving.

We’re seeing:

  • More offshoring (at higher levels, not just transactional work)
  • More hiring from industry
  • More non-CPA advisory talent joining CAS teams
  • More technical “AI fluent” roles emerging

The most successful firms are not just offshoring bookkeeping.

They’re elevating offshore professionals into:

  • Tech optimization roles
  • Reporting specialists
  • Even advisory support

Meanwhile, firms are adjusting internal metrics—reducing strict billable hour pressure—to allow for real training and upskilling.

That’s new.

And it’s necessary.

2026 Priorities: What CAS Leaders Are Focusing On

From dozens of conversations, three consistent priorities are emerging for 2026:

1. Talent Elevation

  • Upskill existing team members
  • Invest in advisory training
  • Improve soft skills
  • Bring in new types of talent

2. Technology Integration

  • Deeper automation
  • AI-assisted workflows
  • Standardized tech stacks
  • Clear advisory enablement strategy

3. Integration & Change Management

  • M&A integration
  • CFO practice roll-ins
  • One-firm thinking
  • Standardized playbooks

CAS leaders must shift from being primary producers to strategic architects.

And that requires space.

The Reframing of the CAS Leader

One of the most critical conversations heading into 2026:

CAS leaders cannot build the future while drowning in client work.

They need:

  • Permission to step back
  • Time to design playbooks
  • Authority to standardize
  • Autonomy to lead change

It’s systems over heroics.

Standardize the close cadence.
Standardize reporting tiers.
Standardize advisory frameworks.

Then coach your people to execute.

A New Definition of Growth

Perhaps the most powerful takeaway from 2025:

Growth is not more clients.

Growth is:

  • Higher margins
  • Better-fit clients
  • More advisory revenue
  • Standardized delivery
  • Elevated talent

If you can increase margins 20% without increasing topline revenue—that’s real growth.

Fix what you have before adding more.

Final Word: 2026 Is the Advisory Year

CAS is no longer compliance.
It is not just automation.
It is not just reporting.

CAS in 2026 is:

  • Advisory-driven
  • Automated
  • Margin-focused
  • Talent-elevated

Let technology carry the routine.
Let people carry the conversation.

And give your CAS leaders the space to build the systems that make it sustainable.

That’s how firms move from CAS… to true advisory.
