At a $50M to $300M contractor, the construction controller owns job cost, the monthly close and the WIP schedule that the surety and the bank read. Hire for the ability to challenge a project manager’s cost-to-complete, not for general ledger skill. Candidates from manufacturing or public accounting usually need a full year to get there.
The surety meets your construction controller’s work before it meets your controller. So does the bank, and so does the CPA firm that signs the review. They read a WIP schedule, form a view of the company from a dozen columns, and only later, if ever, shake the hand of the person who built it. Most contractors hire this seat as if it were a bookkeeping promotion.
What does a construction controller own at a $50M to $300M contractor?
A construction controller owns job cost accuracy, the monthly close, payroll, payables, billing and the work-in-progress schedule. At the lower end of that range the seat also carries the surety, bank and CPA relationships. At the upper end a chief financial officer usually holds those, and the controller produces what they present.
The duties look like any controller’s until you reach revenue. BLS groups the seat with financial managers generally, and the general description fits: reports, controls, compliance. What it leaves out is that a contractor’s revenue is an estimate. Under percentage-of-completion accounting, earned revenue is cost to date divided by estimated total cost, multiplied by the contract. Two of those three inputs are facts. The third is a project manager’s opinion.
That opinion is where the seat lives. A worked example, with invented figures, shows why.
Take a $20M contract with an estimated cost of $18M, so a projected gross profit of $2M. Cost to date is $9M: the job is 50 percent complete, earned revenue is $10M, and with $11.2M billed the job is overbilled by $1.2M. Then the project manager adds $0.75M to the cost-to-complete for a late steel package. Estimated cost becomes $18.75M. The job is now 48 percent complete, earned revenue falls to $9.6M, and projected gross profit drops to $1.25M. Nothing was spent that month. The overbilling still grew to $1.6M, and $0.4M of profit already reported was reversed.
A controller who records that revision is a bookkeeper. One who asked about the steel package in week two, before the project manager was ready to move the number, is what you are hiring. Our piece on the WIP schedule covers how the same document exposes a staffing problem. A homebuilder runs the same discipline house by house, where cost moves through variance purchase orders that a purchasing director answers for.
Why does a controller from manufacturing or public accounting struggle in year one?
Because the general ledger transfers and the revenue model does not. A manufacturing controller is used to standard costs and revenue recognized at shipment. A public accountant has tested WIP schedules without having to produce one against a project manager who would prefer the estimate stayed where it is.
The gaps are specific, and each one has a month in which it shows up.
- Cost-to-complete. In manufacturing, cost is engineered once and variances are measured against it. On a job, the estimate at completion is revised monthly by someone whose bonus may depend on it.
- Underbillings. Cost in excess of billings can be a timing difference. It can also be an unapproved change order being carried as if it were collectible. The schedule shows the two identically.
- Retainage, pay applications and lien waivers. Billing follows a schedule of values an owner or architect certifies, not a shipping document.
- Compliance payroll. A Houston contractor on public work files certified payroll under prevailing wage rules administered by the DOL’s Wage and Hour Division. Nothing in a plant prepares someone for that.
- Multi-state work. An Atlanta contractor running jobs in Tennessee and Florida picks up payroll and sales and use tax obligations in each. Your CPA should map them, and the controller has to run them.
A contractor that builds tax credit apartments adds one more: an audited cost certification, which our note on the affordable housing project executive covers from the delivery side.
None of it is beyond a capable accountant. It is a year of learning done in front of your surety, which is an expensive classroom. CFMA exists largely because construction finance is its own discipline, and membership or coursework there is a reasonable proxy for someone who knows it.
Construction controller or CFO: which seat are you filling?
A controller reports what happened and makes it reliable. A chief financial officer decides what the company can afford to do next: how much work to take on, how to finance it, and what to tell the surety. Many contractors under $100M need the first and advertise for the second.
| Question | Controller | Chief financial officer |
|---|---|---|
| Time horizon | Last month and the current one | Next year and the one after |
| Core document | WIP schedule and job cost reports | Backlog forecast, cash plan, bonding program |
| Surety and bank | Prepares the package, answers job questions | Owns the relationship and the negotiation |
| Works most with | Project managers and project accountants | Ownership, surety agent, banker, CPA partner |
| Typical failure | Accepts every estimate as given | Never sees a job cost report |
The titles blur at $50M, where one person does both and the honest job description says so. They separate somewhere before $300M. If the seat you are filling negotiates the bank line and sets the bonding strategy, read our piece on hiring a CFO instead. On unit-price civil work, where equipment cost allocation sits beside the WIP schedule, the nearer comparison is the heavy civil CFO. If the gap is below the seat, the first hire may be a project accountant.
What should you test in a controller interview?
Test whether the candidate can interrogate a WIP schedule, not whether they can define one. Hand over a six-job schedule with the names removed and ask which job they would call a project manager about first, and what they would ask. The reasoning is the interview.
Four more questions earn their time:
- Ask them to explain an underbilling on a schedule they produced, and what was done about it.
- Ask about a month when a project manager’s estimate was wrong, and how they knew before the job did.
- Ask who they called on day three of the close. Someone who names project managers and superintendents has done the job. Someone who names only the payables clerk has done a different one.
- Ask what the surety agent asked at the last renewal. The SBA’s primer on surety bonds describes what a bond guarantees. A real controller can tell you what the underwriter wanted to see first.
Be straight about the close itself. A candidate who promises a five-day close at a contractor has either not done one or has done one without cost-to-complete meetings. The meetings are the slow part, and they are the part that matters.
The WIP schedule is a negotiation between two departments
Operations and accounting each hold half of every job. The project manager knows what is about to cost money and has not been written down. The controller knows what has been written down and what it does to the statements. The schedule is only as good as the conversation between them, and in most contractors nobody owns it.
That is the real brief for the seat. Not a better accountant: a person who walks to the other side of the building in the third week of the month and asks an awkward question politely. How that depth reads to an underwriter is covered in bonding and bench depth. Contractors across the United States find out which kind of controller they have at the worst available moment, during a renewal.
Who at your firm could explain job 14’s underbilling to the bond agent tomorrow morning? If the answer is nobody, and the seat cannot be advertised while someone is sitting in it, the hire is a case for confidential executive search for mandates that cannot be publicly posted.
