Key takeaways
- The controller owns accuracy: the books, the close, controls and audit.
- A finance director looks forward and partners with the business; the controller looks at what happened.
- Controllers check how a cost is billed and how it can grow, not only its headline size.
- Accuracy, audit trails and cost clarity matter more to them than speed.
What a financial controller is responsible for
A financial controller is responsible for the integrity of the company's financial records and the controls that protect them. The rhythm of the job follows the finance calendar: month-end, quarter-end and the year-end audit.
- Run the month-end close and reconciliations
- Prepare management accounts and statutory accounts
- Oversee payables, receivables and payroll accounting
- Design and test internal financial controls
- Manage the external audit and tax filings
- Approve or check spend against budgets and purchase orders
Financial controller vs finance director and corporate controller
A financial controller keeps the record accurate, while a finance director uses it to plan and to advise the business. In a mid-sized company the controller might report to the finance director, who in turn leads planning, funding and the relationship with the board.
A corporate controller is the group-level version of the role, consolidating the accounts of several subsidiaries. Finance manager is a looser title: in some firms it is a step below the controller, in smaller firms it describes the person doing the controller's job.
How a controller checks a new supplier
A controller checks a new supplier by making sure the commitment, the billing and the paperwork line up with what was approved. The questions are practical: who signed off, is there a purchase order, when and how will invoices arrive, and in what currency.
As an illustration, a team that buys ten seats of a software tool may find the controller asking whether seats can be added mid-term, whether usage is billed separately, and whether an annual payment fits the budget phasing. None of this is obstruction; it keeps the accounts clean.
Why controllers care about how a cost grows
Controllers care about how a cost grows because a predictable bill is easy to budget and an unpredictable one becomes a variance they must explain. Per-seat pricing grows with headcount; usage-based pricing grows with activity; credits and top-ups sit somewhere in between.
A seller who explains clearly what drives the bill, how users can see their own consumption and what happens at renewal answers most of a controller's concerns before they become objections.
What a controller wants from finance software
When the controller is the buyer, for accounting, close or expense tools, they want accuracy, an audit trail and fewer manual reconciliations. They will test a product on their own messy data and ask how it handles exceptions, approvals and corrections.
Claims about time saved mean little without detail. Show the controller each step of the close the product changes, and leave the judgement of value to them.

Common questions
Who does a financial controller report to?
The chief financial officer or the finance director. In a small company without either, the controller may report directly to the chief executive.
Is a controller the same as an accountant?
A controller is usually a qualified accountant, but the role is broader: they lead the accounting team and own controls and reporting rather than doing every entry.
Does a financial controller need a professional qualification?
Most employers expect one, typically a recognised accountancy qualification, along with experience of running a month-end close.
