Ask most people what a Controller does and you'll hear: they manage the close, handle financial reporting, and keep the books clean. That's accurate but incomplete in a way that causes companies to under-hire for the role or under-deploy the person once they're in it. A strong Controller is one of the higher-leverage hires a growing company can make – and the firms that recognize this early tend to build more reliable finance functions as a result.
At minimum, a Controller owns the full close cycle – month-end and year-end – with precision and predictability. That means general ledger integrity, US GAAP-compliant financial statement preparation, reconciliations, accruals, and variance analysis. It also means owning the internal controls that make reporting defensible, and keeping audit readiness current rather than assembled in a scramble before each audit.
Controllers in MAVI's network average eight-plus years of experience and are vetted specifically for close cycle ownership and process-building capability, not just execution.
Most growing finance functions have workflows that were set up quickly and never properly formalized. A good Controller rebuilds the foundation: standardizing the chart of accounts, documenting the close process end-to-end, and implementing controls that hold up under volume and staff changes. It's not the most visible work. It's what makes everything downstream consistent.
Controllers are positioned to surface cost patterns that leadership doesn't always catch – margin drift, budget-to-actual variance trends, expense anomalies worth investigating. A Controller doing this without being asked is delivering a different kind of value than one who only produces what's requested.
Companies preparing for a fundraise, acquisition, or first external audit find that clean books and strong internal controls signal operational maturity to investors and auditors. A Controller with prior audit experience – particularly in SOX or US GAAP environments – makes that scrutiny considerably less painful and expensive.
Whether the company runs on QuickBooks Online, NetSuite, or Sage Intacct, a strong Controller owns the system's integrity rather than just entering data into it. MAVI Controllers are vetted for ERP fluency across all major platforms before placement.
The clearest indicator: your Controller only works reactively – closing books, producing reports, answering questions when asked. A well-deployed Controller proactively flags patterns, identifies process gaps, and contributes to planning conversations. When this is happening, your CFO gets sharper information faster with fewer surprises – and more time for work that genuinely requires their judgment.

A Controller has broader ownership and strategic scope – leading the finance function, owning US GAAP compliance and internal controls, interfacing directly with auditors and board-level leadership. An Accounting Manager oversees day-to-day accounting team operations and the close process, typically reporting to the Controller or CFO.
Not as the primary owner, but a strong Controller works closely with FP&A – the accuracy of actuals directly affects forecast quality. Some Controllers with FP&A backgrounds can bridge both areas effectively in lean teams where the roles aren't yet separated.
QuickBooks Online, NetSuite, and Xero are most common. Controllers in more complex, multi-entity environments should also have exposure to Sage Intacct or Adaptive Insights. All MAVI Controllers are vetted for ERP fluency relevant to your specific stack.
