You built a successful accounting firm, and now you’re trapped inside it. Every client question routes through you. Every tax return needs your eyes before it goes out the door. Your team is talented, but no one knows whose desk the work is on, and your clients couldn’t name their accountant if you asked them to.
Sound familiar?
Unfortunately, you probably built the structure causing all this pain with the best of intentions.
In this episode of Who’s Really the BOSS?, Marcus and Rachel Dillon pull back the curtain on how they restructured their firm, Dillon Business Advisors (DBA), from a bottlenecked, siloed operation into a scalable team-based model. They walk through the exact phased transition that made it work, including the hard conversations, the timing decisions, the mistakes, and the results.
One lesson they learned the hard way, and they keep seeing other firms stumble over it: the biggest mistake accounting firm owners make when restructuring is skipping straight to the end state without working through the messy middle. Building a firm that doesn’t revolve around you requires a phased transition. First, define the roles. Then align the teams and optimize for industry niches. Get the sequence right, and you unlock collaboration, capacity, and career growth for your people. Skip steps, and you’ll create more chaos than you started with.
Let’s break down what that transition actually looks like, starting with the pain points that tell you your current structure is broken, moving through the three phases DBA used to go from chaos to clarity, and ending with what becomes possible on the other side.
The Problem Hiding Behind Good Intentions
Before you can fix your firm’s structure, you have to be honest about what’s broken. What makes this tricky is, the thing that’s broken is probably something you built on purpose.
Marcus describes the symptoms DBA experienced, and they’ll sound painfully familiar to most firm owners. Despite having project management software that technically showed the status of every project, they still didn’t really know where work was. Not in the way that matters, like what a team member was actually waiting on, or why something hadn’t moved in three days. When someone needed time off, or worse, left the firm, there was no reliable way to pick up where they left off without a scramble.
Then there was the silo problem, and this one stings because it started as a smart idea. DBA intentionally created three separate teams: one for individual tax, one for business tax, and one for accounting. On paper, it looked like specialization. In practice, it built unintentional walls.
“The accounting would be done and then passed the baton to the business tax team,” Marcus explains. “The business tax team would do tax returns, and then pass things over to the individual tax team.” The business tax team would be busy at certain times of the year, completely dependent on the accounting team to deliver clean financials, but they had no visibility into what was on that team’s plate. Meanwhile, the individual tax team sat idle, waiting on K-1s, unable to push the process forward or even understand why things were delayed.
Marcus was at the center of it all. Every return needed his review. Every client conversation required his voice. The org chart was a bull’s eye with him in the middle. “I was definitely the bottleneck,” he admits. “I had to have eyes on everything before it went out to a client. It had to be me calling or sitting down with the client.”
The damage wasn’t just internal. Rachel adds the client perspective, and it’s equally sobering. “Clients really didn’t know who their point person was. So when they called, they would ask for Marcus, or they would say, ‘I don’t know who’s working on my tax return’ or ‘I don’t know who’s working on my accounting.'” Things would get lost in translation from person to person. Clients wanted two things the structure simply couldn’t deliver: fast responses and proactive advice.
That’s the real cost of a structure built around one person. It’s not just that the owner burns out. Client experience degrades. Your team knows who they’re working with, but your clients don’t. And when clients feel uncertain about who’s handling their finances, trust erodes until it’s too late.
The Three Phases From Scaffolding to Scale
This is where Marcus and Rachel’s conversation gets practical. They walk through a three-phase approach that DBA used to transition from their old structure to the Team of Three model. Each phase builds on the one before it. Skip ahead, and you’ll pay for it later.
Phase 1: Define the Roles (Build the Scaffolding)
Before you can organize teams, you need to know what roles exist. DBA’s Team of Three consists of three clearly defined positions:
- Client Service Manager (CSM). The base of the team. Marcus describes them as “an accountant, a bookkeeper, somebody with experience who doesn’t have to have a degree.” Many of DBA’s CSMs are working parents who want a career that offers flexibility alongside meaningful work. They operate at 85% capacity, with 15% reserved for onboarding new clients and handling the inevitable surprises.
- Client Controller. Someone with tax experience who has “seen accounting and done closeouts,” Marcus explains. “Maybe they’ve done the bookkeeping cleanup at year end, and they can produce clean financials.” They can prepare business tax returns and advise on personal and business tax matters. When DBA hires for this role, they post it as “tax manager” because posting “client controller” attracts candidates who misunderstand the position.
- Client CFO. This person manages the team and drives the client relationship. “They can have larger business strategy and tax-related conversations with clients as needed or consistently throughout the year,” Marcus notes. Business ownership experience is a big plus here because it gives them risk tolerance and the ability to connect with entrepreneurial clients.
With those three roles defined, DBA assessed its existing team and started mapping people into positions. Some placements were obvious. Others required difficult conversations.
“We didn’t want to force people into a certain role,” Marcus explains. They had direct conversations with team members. “Here are the guidelines of each role, here’s what each one would do. What would you like to do? Where do you feel most comfortable?”
Rachel adds an important nuance about those conversations. “There were team members who had been with us a long time, and they were leaders within our firm. They were experienced, degreed and very good accountants. But if you think about it vertically, they’re the bottom.” It was important to help them understand that CSMs have significant client interaction and hold important relationships. They found other ways for these team members to lead through onboarding, training, mentoring, or becoming subject matter experts.
Marcus admits to a mistake from this phase. “We kept some people on too long. They clearly weren’t fully a client controller. They had a leg in CSM and another in Client Controller for just a little bit too long. And it didn’t work out.”
Phase 2: Align the Teams (Set the Team Structure)
Phase 2 is where the real transformation happens, and where it often breaks down for other firms.
After Phase 1, DBA had people in defined roles. But those people weren’t working in consistent teams. “Even with myself as maybe the only client CFO at that time, we had close to 40 different teams of three within our team of 12 or 10 FTEs,” Marcus reveals.
Rachel paints the picture. “A CSM on our team was working with three different controllers. So three people give her work, ask her questions or request things from her. During tax season, everyone’s busy. Who do I prioritize work for?”
The solution was a deliberate reorganization and locking in which three people would serve which clients. DBA used a straightforward decision framework. If two of the three team members were already working with a client, those two stayed. Swapping out two of three required exceptional justification, such as a team member having a relationship that overrode the numbers.
The timing was strategic. They planned the reorg in March and April, then communicated it to clients after tax season. “After tax season, we actually pushed through the reorg and communicated to clients,” Marcus explains.
Clients reacted well. “They said, ‘Okay, we know you have what’s in our best interest. We trust you. I didn’t lose my person.'”
The internal results were dramatic and fast. “Within a month, efficiencies and budgets improved,” Marcus reports.
Phase 3: Optimize and Refine (Industry Niches and Career Paths)
With teams aligned and running smoothly, DBA could finally build industry specializations. They organized pods around verticals: dental, veterinary, and medical professional services. Construction and real estate were sprinkled across every team, since many clients own real estate.
This created real advisory value. “When I have advisory conversations, that’s what they typically ask me: ‘Well, how’s everybody else doing?” Marcus shares. “Because I want to know, am I the only one who’s going through this difficult time?”
Phase 3 also made career progression visible. “It gives people a clear path to move if they want to do that career ladder,” Marcus explains.
Marcus’s own evolution shows the ultimate success. “I’ve given away clients and team members to other people who are progressing in their careers.” He adds, “After the client meets the team, they forget about me.”
“Sometimes starting at phase three is the problem, or not doing phase one and phase two well,” Marcus warns. “The firms that have success with this start with role definition and then move to defining teams and then optimizing or refining.”
What The Right Sequence Unlocks
Step back and look at what DBA built through this phased approach. Each phase created the foundation for the next breakthrough.
- Collaboration over silos. Teams know each other’s workloads and can step in when needed. There’s no single point of failure on any client. “If a team member needs to be out, the client is still going to be fully served and their team is available,” Rachel explains.
- Consistency through tax season. Marcus calls out a common industry problem where firms sell clients on recurring advisory work, then stop delivering it from January through April. “You should have the bandwidth and the capacity to serve those clients consistently all year long, including tax season. If you’re signing somebody up for recurring ongoing financial support, which is what most people do in CAS, you have to do that consistently.”
- Real capacity for growth. After the Phase 2 reorg, Rachel notes, “Those team members actually had enough capacity to take on clients without being overloaded with work or going above their peak capacity.”
- Career development without departure. Team members don’t have to leave to advance. Marcus shares, “Our team members don’t have to go outside of DBA to continue to progress in their careers.”
Marcus and Rachel have seen what happens when firms skip steps. Firms that jump straight to building industry pods without first defining roles end up with confused team members. Firms that try to align teams without clear role definitions create accountability structures with nothing to be accountable to.
The sequence is the architecture that makes everything else work.
Your Move: Define, Align, Then Optimize
The Team of Three model gave DBA a destination. But the phased transition got them there. Most firm owners who struggle with restructuring try to implement the final version on day one.
Whether your firm has five team members or 50, the principles hold: clarity before alignment, alignment before optimization. Your team needs to know their role before they can function as a unit. Units need to gel before you can specialize.
If you’re feeling stuck as the bottleneck in your firm, or you’ve tried restructuring and it created more chaos than clarity, Marcus and Rachel share more details about each phase in this episode of Who’s Really the BOSS?. They discuss the specific mistakes they made and how they coach other firms through the same transition.
Marcus closes with an invitation: “We have a lot of resources. If anybody wants to reach out about any of those resources, job descriptions, benchmarks, scorecards, all that fun stuff. We have those in the Collective community. But if something is sticking out, please reach out.”
