A lot of CPA firms look healthy on paper.
Revenue is coming in, clients are active and the business feels stable. But the real pressure on EBITDA usually comes from inside the firm, where small inefficiencies build up quietly over time.
Across most CPA firms, these issues are not random, they tend to show up in the same areas.
1. Too Much Low-Value Work Hiding Inside the Firm
A lot of firms are still buried in compliance work, telling themselves that higher-margin advisory will come later. But when technology investment is too light, senior people end up spending expensive hours fixing messy books, cleaning up client files and handling work that should have been pushed down or systemized long ago.
That same margin pressure often shows up in client scope creep. Extra client requests, small favours, extra review cycles and cleanup work outside the original engagement are often absorbed quietly because no one wants friction with long-standing clients. While those clients may still look profitable, the firm is often delivering far more than it invoices for.
We recently heard from a partner about a team member so focused on accuracy that the firm ended up spending roughly $5,000 of internal resources fixing a $200 mistake on a client file.
When high-billers are stuck doing low-value work and too much extra work goes unbilled, EBITDA gets squeezed more than most firms realize.
2. Senior Staff Doing $25-an-Hour Work
This is one of the fastest ways to damage EBITDA.
In many CPA firms, partners and senior managers are not just leading client work. They are also pulled into recruitment, HR decisions, admin, workflow chasing and manual follow-ups that take time away from higher-value work. When experienced people are spending expensive hours in the wrong places, leverage across the firm starts to weaken and EBITDA gets dragged down with it.
A lot of this can now be minimized with better systems, clearer delegation and the thoughtful use of AI to handle repetitive admin and workflow-heavy tasks.
3. Legacy Knowledge Instead of Real Systems
Some firms still run on the memory and instincts of a few key people.
They know how the files move.
They know which clients need special handling.
They know where the exceptions sit.
That may work internally for years. But when CRM, billing, workflow and client information all live in different places, inefficiency becomes embedded in the operating model. Manual invoicing slows down cash collection. Manual data entry wastes staff time. Inconsistent processes create more errors, more rework and more dependency on certain employees.
When knowledge lives in people instead of written processes and workflow systems, margin becomes harder to protect, harder to measure and much harder to scale.
What feels operationally manageable day to day can quietly drag EBITDA down every month.
4. “Special Snowflake” Clients
Every firm has them.
Clients with custom processes, unusual demands, off-cycle requests and workflows that do not match how the rest of the firm operates.
The problem is not that they are difficult.
The problem is that they quietly destroy consistency. They consume disproportionate time, create internal workarounds and drag down firm profitability in ways that standard reporting often misses.
5. The Price of Playing It Safe
A lot of firms still price conservatively.
They keep prices steady to win work. They sometimes underprice to keep long-term clients happy. They avoid repricing because they worry clients will leave, push back or start comparing fees more closely.
In many firms, pricing also goes untouched simply because no one owns it. Annual increases are not built into the client process, partners are too busy to review accounts properly and legacy clients often stay on old pricing far longer than they should.
A number of firm partners have told us they increased revenue by as much as 25% in 2026, simply by repricing clients and breaking old pricing habits.
6. The Indispensable Owner Trap
This remains one of the biggest hidden costs inside a CPA firm and it affects more firms than partners often realize.
If the owner, CEO or managing partner holds most of the client relationships, approves everything important and acts as the glue across operations, buyers will view the firm as riskier than the numbers suggest.
That is because replacing a founder is rarely a simple transition. It usually requires more hiring, stronger systems and far more transition planning than buyers expect to take on.
Final Thought
The biggest EBITDA issues inside CPA firms usually do not show up as major failures. They show up as small inefficiencies that have been tolerated for years.
A bit of underpricing here.
Too much partner time spent in the wrong places there.
A few messy clients.
A team that relies too heavily on memory instead of process. And missed opportunities to build higher-margin divisions such as SR&ED, fractional CFO or Cybersecurity.
Individually, these things may not seem serious.
Together, they can materially weaken both EBITDA and the long-term growth potential of the firm.
At RSSL Mergers, we spend a lot of time looking at what makes CPA firms more valuable, more scalable and more attractive to buyers. Often the biggest gains do not come from adding more revenue. They come from fixing what is quietly dragging EBITDA down in the first place.
