What is a fractional controller?

A fractional controller is an experienced accounting leader who manages a company's accounting function part-time. They own the month-end close, produce accurate GAAP financial statements, set up internal controls, manage bookkeepers and prepare the company for audits and tax. Most engagements cost $2,000–$8,000 a month.

A controller sits between your bookkeeper and your CFO. The bookkeeper records transactions. The controller makes sure the books are complete, correct and closed on time, and that the financial statements follow accounting standards. The CFO uses those numbers to plan and raise money.

Most companies don't need a full-time controller until they have a sizable finance team. Before then, a fractional controller gives you the same expertise for a few days a month: a reliable close process, clean revenue recognition, reconciled accounts and controls that stop errors and fraud.

It's often the first finance hire to make. A CFO is only as good as the numbers underneath, and many fractional CFOs ask for a controller before they start.

Fractional vs full-time cost

A full-time controller costs about $216,000 a year once salary, payroll tax and benefits are included. Most companies under $20M–$30M in revenue don't have enough controller-level work to fill a full week, which is why the fractional model is so common.

What drives the price

Transaction volume

More invoices, bills, payroll runs and bank accounts mean more hours.

Revenue recognition

SaaS contracts, usage billing, inventory and multiple entities all add complexity.

State of the books

Messy books need a cleanup project before the monthly retainer settles down.

Audit requirements

An upcoming financial audit or due diligence adds controls and documentation work.

What a fractional controller does

A fractional controller owns the accuracy of your numbers. That usually covers these areas.

Month-end close

A documented close checklist that finishes in days, not weeks.

GAAP financial statements

Income statement, balance sheet and cash flow you can hand to investors or a lender.

Revenue recognition

Correct treatment of contracts, deferred revenue and multi-element deals.

Internal controls

Approval rules, separation of duties and reconciliations that catch errors early.

Audit and tax readiness

Schedules and documentation for auditors and your tax preparer.

Team and systems

Managing bookkeepers or an outsourced firm, and choosing the right accounting tools.

Fractional controller vs bookkeeper vs fractional CFO

Three roles that are often confused, and what each one does.

Role Focus Looks Typical cost
Bookkeeper Recording transactions, paying bills, payroll Day to day $500–$2,500/mo
Fractional controller Close, accuracy, GAAP, controls Backward: what happened $2,000–$8,000/mo
Fractional CFO Forecasting, strategy, fundraising Forward: what to do next $3,000–$15,000/mo

Most growing companies need all three layers, each part-time. If you can only afford one senior hire and your books are unreliable, start with the controller.

When to hire a fractional controller

These are the most common triggers.

When not to hire one: Small businesses with simple cash-based books and no audit requirement can usually rely on a good bookkeeper and an outside accountant.

The close takes too long

Financials arrive three to six weeks after month end, too late to act on.

Numbers keep changing

Last month's results get revised, and leadership stops trusting the reports.

An audit or diligence is coming

Investors, lenders or a buyer will look at your books in detail.

You've outgrown your bookkeeper

Revenue recognition, multiple entities or inventory are beyond their experience.

Mentors with Financial Controller experience

Senior operators who have done this job. Many offer an intro call, so you can check fit before you commit.

Questions to ask before you hire a fractional controller

Ask about specific outcomes, not credentials. A good candidate will tell you what didn't work as readily as what did.

  1. 1

    Which accounting systems and industries have you worked in?

  2. 2

    How long would our close take once your process is in place?

  3. 3

    Have you prepared a company for its first audit?

  4. 4

    How do you work with our bookkeeper or outsourced firm?

  5. 5

    Do you expect a cleanup project first?

What does a fractional controller do?

A fractional controller owns the accuracy of your books part-time: running the month-end close, producing GAAP financial statements, setting up internal controls, managing bookkeepers and preparing for audits and tax.

What's the difference between a controller and a CFO?

A controller looks backward and makes sure the numbers are accurate and complete. A CFO looks forward and uses those numbers for forecasting, strategy and fundraising.

Do I need a controller or a bookkeeper?

A bookkeeper records transactions. A controller checks and closes the books, applies accounting standards and owns controls. Once you have audits, investors or complex revenue, you usually need both.

When should a company hire a fractional controller?

When the month-end close takes too long, numbers keep changing after the fact, an audit or due diligence is coming, or the business has outgrown its bookkeeper.
