5 Questions to Ask Before Hiring a Fractional CFO for a Contracting Business

Hiring a fractional CFO is a bigger decision than hiring a bookkeeper, and the specialization gap is wider. A capable generalist CFO can read your financials and give sound advice for most businesses. Contracting is not most businesses. The way money is made, lost, stuck, and timed in a trades business is specific, and a CFO who has not lived it will give you answers that are correct in general and wrong for you.

These five questions surface the difference fast.

1. How do you measure true job-level profitability?

Company-level profit is the easy number, and it is the one that hides the problem. Ask how they would tell you which individual jobs made money and which lost it. A contractor CFO will talk about allocating fully-burdened labor, materials, subs, and overhead to each job, and about the fact that most contractors cannot see this because 91% of jobs carry revenue with no cost data attached.

A generalist will point at the P&L. But a company-level P&L can look healthy while some of your jobs quietly lose money, subsidized by the winners. The whole point of a contractor CFO is to make that visible.

2. How do you read a WIP schedule, and how do you catch profit fade?

For project work, the work-in-progress schedule is where a contractor CFO earns the fee. Ask them to explain over/under billing and profit fade, and how they would use the WIP each month.

A trades CFO will describe watching estimated-cost-at-completion creep, catching a job's margin eroding while there is still time to reprice or control it, and reconciling the WIP to the P&L. A generalist may never have built one. Fade is invisible on a standard income statement until the job closes, and by then it is too late. (WIP explained.)

3. How do you manage the gap between paying crews and getting paid?

This is the contractor CFO's core, everyday job, and the answer tells you whether they understand trades cash. Ask how they would handle a business that is profitable on paper but keeps running short on cash.

A specialist immediately reframes it as timing and collection, not profit: contractors pay crews weekly but collect in weeks to months, the median contractor collects only 85.1% of what they bill, and retainage locks up earned cash. They will talk about billing speed, an AR escalation cadence, and separating retainage from normal receivables. A generalist will suggest cutting costs, which misses the point entirely.

4. How do you think about labor?

In a trades business, skilled labor, not demand, is usually the binding constraint. Ask how they think about it. A contractor CFO will talk about gross profit per billable hour, technician utilization, and the fact that a shop can grow revenue while making less per hour worked. (Gross profit per hour.)

A generalist CFO tends to treat labor as a cost line to minimize. In the trades, the right question is not "how do we spend less on labor" but "how much gross profit does each field hour produce, and how do we protect and price it." If they do not frame it that way, they do not understand the business.

5. What two or three numbers would you put in front of me every week?

The answer reveals judgment. A weak CFO lists a dozen metrics or hands you another dashboard. A strong contractor CFO names a short set you can act on, usually some combination of job-level margin on recent work, cash position and collections, and gross profit per hour, and explains why each one drives a decision.

You are not hiring someone to produce reports. You are hiring someone to tell you the two or three things that matter this week and what to do about them.

Why specialization changes the equation

A fractional CFO is expensive enough that the wrong fit is a real cost, not just an annoyance. The advantage of a trades-specialist, outsourced CFO is that the hard-won know-how is already built: job costing, WIP, cash timing, and labor economics have been solved for other contractors, so you get the judgment without paying for the learning curve or carrying a full-time executive salary.

At Level, these five areas are the job, not the extras. We connect the field system and the accounting system, reconcile them into a job margin you can trust, and put the two or three numbers that run the business in front of you every week. If you are weighing a fractional CFO, these are the questions worth asking whoever you talk to, including us.
