What Does a Controller Do in Finance
A controller is the person accountable for the accuracy of a company’s financial records: the monthly close, internal controls, accounts payable and receivable oversight, and the reporting package leadership and the board actually rely on. A controller does not just record transactions, they design the process that produces reliable numbers on a predictable schedule and sign off on them before anyone else sees them. At Treewalk, we run this function for growing companies, First Nations, and public issuers as a fractional or outsourced team, so a client gets a full controllership department without carrying the headcount of one.
What a controller actually does, day to day
The title gets used loosely. In practice, a controller’s job breaks into four buckets:
Owning the close.
Reviewing and approving journal entries, reconciling accounts, and producing financial statements on a fixed cadence, not “whenever the books are ready.”
Running internal controls.
Segregation of duties on payments, approval chains on invoices, and a process that catches errors before money moves, not after.
Managing the team.
A controller directs the bookkeepers, AP/AR staff, and payroll function underneath them. They are not the one keying invoices.
Translating numbers for decision-makers.
A controller hands leadership a package they can act on: variance explanations, cash position, and flags, not a raw trial balance.
Controller vs CFO: who is higher
A CFO sits above a controller. The CFO sets financial strategy, owns forecasting, banking relationships, and capital decisions, and reports to the CEO or board. The controller reports into the CFO (or directly to the CEO in smaller companies) and owns the accuracy of the historical record the CFO builds strategy on top of. Put simply: the CFO decides where the company is going financially, the controller makes sure everyone can trust the numbers describing where it’s been and where it stands today. Many organizations run both functions fractionally at once, since the two roles need different skill sets and rarely justify two full-time hires until a company scales well past its startup years.
Is a controller a high position
Yes. Controller is a senior finance role, typically the most senior accounting position below the CFO, and often the highest-ranking finance seat in smaller organizations that have no CFO at all. It carries real authority: sign-off on financial statements, control over the payment approval chain, and direct oversight of the accounting team. Seniority does not mean scale, though. A controller can run a five-person accounting function or a fifty-person one; the accountability is the same either way.
How we approach controllership at Treewalk
Most of the controllership work we inherit isn’t a clean handoff, it’s a cleanup. Books that were “fine” for years until a lender, a board, or a regulator suddenly asked a question nobody could answer cleanly. In our experience, a books problem is not a problem until it is one. Latent bookkeeping problems don’t announce themselves. They surface at the worst possible moment, and by then you’re solving them under pressure instead of on a schedule.
Our approach starts from a control most companies get backwards.
A controller should never have to ask permission to see their own bank statements. If you’re locked out of your own accounts, that’s not a controls problem, that’s an access problem, and it usually means the person who set up the process wanted leverage, not security.
We also hold to a simplicity rule: build the control the company actually needs, not the one that looks impressive. Overbuilt processes cost more hours and don’t catch more errors. And we treat the close itself as a discipline, not a scramble. A five-day close is a realistic, defensible target once the controls and the team underneath them are set up correctly. A close that depends on one heroic person working the weekend is a close that will eventually break as the company grows.
Common misconceptions
The biggest one: audit experience prepares someone for controllership. It doesn’t, not on its own. Auditors are trained to test someone else’s controls after the fact. A controller has to build and run the controls themselves, in real time, inside a live business. Reviewing a payment cycle once a year and owning it every single day are different skill sets, and firms that staff controllership roles purely with audit backgrounds are often surprised by the gap.
Frequently asked questions
How much do financial controllers get paid?
Compensation varies significantly by region, industry, and company size, and we don’t publish salary figures since they shift too often to be reliable in writing. What stays consistent is that controller compensation sits below CFO and above senior accountant, reflecting the seniority of the role.
Is a controller the same as a bookkeeper?
No. A bookkeeper records transactions. A controller designs the process, reviews the output, owns the controls, and is accountable if the numbers are wrong. A controller may have started as a bookkeeper, but the job is fundamentally different once you’re the one signing off.
Do we need a controller if we already have a CFO?
Usually yes, unless the company is small enough that one fractional person is covering both roles. A CFO focused on strategy and fundraising typically doesn’t have the bandwidth to also review every reconciliation and approve every payment. Splitting the two roles keeps both functions done properly.
How is Treewalk’s controllership different from a solo hire?
When you hire us, you’re hiring a firm, not a person. There’s a backstop, documented processes, and no single point of failure if one team member is out. There are no vacations and no sick days on our watch: our uptime is 100 percent.
Where to next
If your close depends on one person and you’re not sure what happens the day they’re unavailable, that’s usually the first sign it’s time to talk to a controllership team. Our private companies practice runs outsourced and fractional controller functions for growing businesses, and our public companies team handles the same discipline under public-company reporting requirements. Reach out to our team to talk through what your close actually needs.
