Bookkeeper, controller, CFO: which one you need at $3M

Somewhere around a few million dollars in revenue, most owner-operated businesses hit the same wall. There is a good bookkeeper. The bills get paid and the invoices go out. But the monthly statements arrive late or not at all, the bank asks questions nobody can answer quickly, and the owner is still running the business by looking at the bank balance.

The usual reaction is to ask whether it is time to “get a CFO”. Often the answer is that the missing piece is a controller. The three roles are different jobs, and it helps to be precise about them.

The bookkeeper records

A bookkeeper’s job is to get transactions into the ledger accurately and on time: bills entered and paid, customer invoices issued, payments applied, payroll recorded, bank feeds categorised. A good bookkeeper is the reason the books exist at all.

What a bookkeeper is not usually asked to do is decide whether the month is finished. Recording a transaction and proving that the balance sheet is right are different skills. Most bookkeepers work forward, one transaction at a time. The questions that matter to a lender are about the whole: are receivables collectable, are all the liabilities recorded, does cost of sales match the revenue it belongs to?

The controller closes

A controller’s job is to make the numbers true and deliver them on a schedule. In practice that means:

• running a month-end close to a checklist and a date;
• reconciling every bank, card and loan account, and supporting every balance-sheet account with a schedule;
• making the adjusting entries a bookkeeper would not know to make: accruals, prepaid expenses, job cost cut-off, over and under billings;
• producing a monthly package, the profit and loss, balance sheet and cash flow, with a short written explanation;
• setting the controls that keep it that way: who can pay whom, who approves what.

The output of a controller is a set of statements you can hand to a lender or a bonding agent without apologising for them, delivered on the same business day every month.

The CFO decides

A chief financial officer works forward from those statements. Capital structure, bank relationships, acquisitions, raising money, long-range planning and the strategy that sits behind the budget are CFO work.

The important point is the order. A CFO’s judgement depends on reliable monthly numbers. A CFO hired into a business without a working close tends to spend the first year doing a controller’s job at a CFO’s cost.

What each one costs you

Salary alone understates every one of these hires. Loaded for Florida in 2026, meaning base pay plus payroll taxes, a single-coverage health plan, a 3% retirement match, a bonus, software and the cost of recruiting spread over three years, the figures look like this:

Without health cover or a retirement match, which is common below a few million in revenue, the bookkeeper comes down to about $61,146 and the controller to about $141,994. None of these figures includes the owner’s time managing the hire, the months before a new person is productive, or the cost of replacing someone who leaves. The sources and every assumption are on our pricing page.

For a company at a few million dollars of revenue, the full-time controller is often the step that does not fit. The work is real but it is not forty hours a week, and a single hire is a single point of failure when that person leaves. Many businesses at this size hire a “controller” who is, by the government’s job definitions, a senior bookkeeper; that hire is the second row of the table.

That is the gap fractional work fills: the controller’s discipline, for the hours the business actually needs, at a fixed monthly fee. At MTL Services, Controller Essentials covers $1M - $3M of revenue at $2,000 a month with 8 included hours. Controller + Cash covers $3M - $6M at $3,500 with 15 hours. Per hour, that costs more than an employee. Per year it costs less, because you buy the hours the work takes rather than a full-time salary. The bookkeeper stays; the controller work sits on top.

Signs you have outgrown the bookkeeper

None of these is a criticism of the bookkeeper. They are signs the job has grown past what bookkeeping covers.

1. You manage by the bank balance. You know what is in the account today, but not what you earned last month or what you owe next month.
2. Statements arrive late, or only at year end. If the profit and loss for March arrives in May, it is history, not information.
3. The balance sheet has mystery accounts. Suspense, “ask my accountant”, undeposited funds and clearing accounts with balances nobody can explain.
4. Receivables and payables do not match reality. The aging report shows invoices you know were paid, or bills you know are wrong.
5. The lender or surety asked for something you could not produce. A covenant calculation, a WIP schedule, a quarterly balance sheet.
6. Gross margin swings from month to month without a business reason. Usually a cut-off problem: costs and the revenue they belong to are landing in different months.

Two or three of those together usually mean the business needs a close, not a better bookkeeper.

Where to start

Before anyone commits to a monthly engagement, it is worth knowing how far the books are from closable. A free consult, 30 minutes, is where that starts. We ask about revenue, entities, who does the books today, what your lender or surety asks for, and what is late. Then we tell you whether the Diagnostic is needed or you can start with Controller Essentials directly.

When the books need a proper look first, the Financial Health Diagnostic costs $2,500 and takes 10 business days. Credited to month one of any band signed within 30 days.

If the answer is that the bookkeeper is doing fine and the business is not yet at the size where a close pays for itself, we will say so.
