Most fast-growing companies underbuild their finance function for longer than they should. Sales gets headcount. Product gets headcount. Finance gets a controller and a prayer.
It’s an understandable pattern. Finance doesn’t generate revenue directly, and the cost of under-investing is often invisible until it isn’t — until the books are months behind, the board is asking questions that can’t be answered quickly, or a transaction surfaces gaps that should have been closed a year ago.
The question isn’t whether to invest in your finance team. It’s what the right investment looks like at your specific stage — and how to sequence the hires so each one builds on the last.
Based on Clarity’s experience placing finance and accounting professionals across hundreds of high-growth companies in Canada, here’s how to think about finance team structure from early startup through enterprise scale.
We’ve also built finance team org chart templates for each stage referenced below.
Before getting into the specifics of each stage, a few principles that apply across all of them.
The finance function is not just accounting
Accounting — recording, reconciling, reporting on what happened — is table stakes. The finance function that actually drives growth does something different: it connects data across the business, builds forward-looking models, identifies opportunities and risks before they become urgent, and gives leadership the analytical foundation to make better decisions. As you build your finance team, distinguish between hires that improve the historical record and hires that improve decision-making. You need both, but in the right order.
Full-time vs. fractional is a structural decision, not a cost-cutting measure
At every stage of growth, there are roles that require full-time dedication and roles that can be filled more efficiently with fractional or contract expertise. This isn’t about finding cheaper options. It’s about getting specialized expertise exactly when you need it without carrying the overhead of a full-time hire in a function that doesn’t yet need one. A $15M company probably doesn’t need a full-time FP&A analyst. It might need one for 20 hours a week during budget season. Getting this balance right is one of the highest-leverage finance decisions a growing company makes.
Structure follows strategy — but not with a long lag
The right finance team structure today is the one that supports where the business is going over the next 18–24 months, not just where it is right now. Hiring a CFO when you’re already in the middle of a transaction is reactive. Building the team with enough lead time that the finance function is ready before the business needs it is how the best companies operate.
Recommended team size: 1–3 | Key hire: Controller or VP of Finance | Consider: Fractional CFO
At this stage, the finance function’s primary job is to keep the books clean, manage cash, and give the founder or CEO enough visibility to make good decisions. That’s not a small job — it’s just a focused one.
The core hire
Most companies at this stage don’t yet need a full-time CFO. What they need is a capable Controller or VP of Finance who can own the accounting function, manage reporting, and bring credibility to the numbers. This person should be comfortable with financial modelling and growth planning — not just transactional accounting — because they’ll be asked to do both.
When to add a fractional CFO
If you’re sub-$5M and working toward a Series A, or if you’re approaching $5–10M and starting to field investor questions your current finance leader isn’t equipped to handle, a fractional CFO is often the right complement. They bring strategic credibility and investor fluency without the cost of a full-time hire. The model works when your fractional CFO is genuinely senior — someone who has been in the CFO seat before, not a consultant running reports.
The rest of the team
One to two people in support roles — handling AR/AP, payroll, and transactional accounting — is typical at this stage. These can be full-time junior hires or part-time contractors depending on volume. Outsourced bookkeeping can work here if the finance leader has the bandwidth to oversee it properly.
Warning signs you’ve outgrown this structure
Recommended team size: 3–5 | Key hire: CFO | Consider: FP&A, systems/ERP specialist
This is the stage where most companies realize their finance function has quietly become a bottleneck. Revenue is growing, the business is getting more complex, and the Controller or VP of Finance who was excellent at keeping up with transactions is now being asked to do things they weren’t hired to do.
The CFO hire
At $10–20M in revenue — and earlier if you have a PE sponsor or institutional investors — a full-time CFO becomes necessary. The CFO at this stage is primarily a growth enabler: they own the financial strategy, manage the board relationship, lead fundraising processes, and build the team and systems that will support the next phase of growth. They should not be doing the accounting.
If a permanent CFO search will take three to four months and you need someone now, an interim CFO can fill the gap and in many cases do meaningful work on the finance function while the permanent search runs.
Specialization starts here
With a CFO in place, the finance team can start to specialize. The most common additions at this stage:
The fractional model still applies
Not every specialized need requires a full-time hire. FP&A support during budget season, a project accountant for a specific initiative, an interim finance leader during a transition — fractional and contract resources remain a valuable part of the finance team structure at this stage. The difference is that someone (your CFO) now owns the decision about when to use them.
Warning signs you’ve outgrown this structure
Recommended team size: 6–10 | Key hires: FP&A lead, Accounting Manager, specialist roles | Consider: M&A, internal controls, treasury
By this stage, the finance function should be well-established — a seasoned CFO, a functioning accounting team, and at least the beginning of a real FP&A capability. The work at this stage is about depth and specialization: building the layers of expertise that allow the finance function to support a significantly more complex business.
The FP&A build-out
FP&A becomes a genuine function at this stage, not just one analyst supporting the CFO. A Director or VP of FP&A, supported by analysts focused on specific business units or functions, gives the organization the planning and analytical depth it needs to make good decisions at scale. The FP&A function at a $100M+ company should be running rolling forecasts, building business case models for major investments, and providing the CEO and leadership team with visibility into performance that goes well beyond monthly actuals.
Accounting specialization
As the business grows, accounting splits into its constituent parts: revenue accounting, cost accounting, consolidation, technical accounting for complex transactions. A strong Controller with a team of accounting managers — each owning a specific domain — is the right structure here. The days of one person owning the entire accounting function are behind you.
New specialist needs
Three areas commonly require dedicated or fractional expertise at this stage:
Warning signs you’ve outgrown this structure
Recommended team size: 11+ | Structure: Multi-layered, fully specialized | Focus: Governance, strategic finance, talent development
At enterprise scale, the finance function is a fully developed organization within the organization. The CFO’s job is less about doing finance and more about leading a finance organization — setting strategy, developing talent, managing the relationship between finance and the rest of the business, and ensuring the function continues to evolve as the company does.
Full specialization across all functions
By this stage, every component of the finance function has dedicated leadership and supporting teams: financial reporting, FP&A, treasury, tax, internal audit, investor relations (if public), M&A, and finance business partners embedded in major business units. Each function has its own leadership, processes, and talent development path.
Finance business partners
One of the most impactful structural decisions at enterprise scale is embedding finance business partners within the major operating functions of the business — commercial, operations, product, people. These are finance professionals who sit with the business, understand the operational context, and translate financial data into decisions. They are the connective tissue between the finance function and the rest of the organization.
Talent development becomes a CFO priority
At this stage, the CFO is also accountable for building the next generation of finance leaders within the organization. A structured approach to talent development — identifying high-potential finance professionals, giving them stretch assignments, and managing the succession pipeline — is as important as the structural decisions about roles and reporting lines.
Across all four stages, one of the most consequential decisions is how to fill specific finance needs — with a permanent hire, an interim executive, or a fractional resource. Here’s a simplified framework:
Use a permanent hire when:
Use an interim CFO or finance executive when:
Use a fractional or contract resource when:

For an early-stage startup under $10M in revenue, a lean finance team of one to three people is typical. The core hire is a Controller or VP of Finance who owns reporting, cash management, and basic financial planning. Many companies at this stage complement that hire with a fractional CFO who brings strategic and investor-facing experience without the cost of a full-time executive. One to two support staff or contractors handle transactional accounting.
Most high-growth companies benefit from a dedicated CFO somewhere between $10M and $20M in revenue — earlier if they have PE backing or institutional investors who expect senior finance leadership. The signal isn't the revenue number alone; it's whether the current finance function can give leadership and the board accurate, forward-looking financial visibility. When it can't, the CFO hire is overdue.
At $50M in revenue, a finance team of five to eight people is typical for a high-growth company. This usually includes a CFO, a Controller or VP of Finance, one to two FP&A resources, an accounting manager, and one to two staff accountants or analysts. The exact structure depends on the complexity of the business, the reporting requirements of investors, and how much of the function is supported by fractional or outsourced resources.
A Controller is primarily responsible for the accuracy and integrity of financial records — managing the accounting function, overseeing month-end close, and producing reliable historical reporting. A CFO operates at a higher strategic level: owning the forward-looking financial plan, managing investor and board relationships, leading capital allocation decisions, and building the finance team. Growing companies need both, but they serve different purposes. A strong Controller doesn't replace a CFO.
Yes, in several ways. PE-backed companies face higher reporting expectations, more rigorous covenant compliance requirements, and closer board scrutiny than comparable non-investor-backed businesses. This typically means investing in CFO-level leadership earlier, building a stronger FP&A function sooner, and maintaining a higher standard of financial reporting from day one. PE sponsors generally expect a dedicated, full-time CFO in place — not a fractional arrangement — and value finance leaders who have prior experience in PE-backed environments.
Fractional and contract finance professionals are most valuable when you need specialized expertise for a defined period or project — ERP implementation, IPO readiness assessment, audit support, a specific FP&A build. They're also the right model when the business doesn't yet justify a full-time hire but the need is genuine and ongoing. The key is that someone internal — ideally a CFO or VP of Finance — owns the relationship and ensures the work is integrated with the rest of the finance function.
The sequencing matters as much as the roles themselves. The typical order: first, a Controller or VP of Finance to establish accounting integrity; second, a CFO to lead strategic finance and investor relations; third, FP&A capability to move from historical reporting to forward-looking planning; fourth, accounting specialization as transaction volume and complexity grow; fifth, specialist functions like treasury, tax, and internal controls as the business reaches scale. Interim and fractional resources can fill gaps in this sequence without the overhead of premature permanent hires.
