CASH FLOW

CONSTRUCTION CASH FLOW PROBLEMS, EXPLAINED.

QUICK ANSWER

Construction cash flow problems almost always trace back to three causes: billing lag between cost incurred and cash collected, no rolling cash forecast to plan around the shortfalls you already know are coming, and job profitability that's tracked at closeout instead of weekly. A subcontractor can be genuinely profitable on the P&L and still end up with no cash left because none of those three are being managed as a system.

Cash flow problems in construction rarely mean the business isn't making money. They mean the distance between spending cash and collecting it's going unmanaged, and that distance compounds across every job active at the same time. Mobilization costs, retainage, slow pay cycles, and unbilled change orders all pull cash out of the business before the P&L ever reports a loss. Fixing cash flow isn't about becoming more profitable. It's about building a system that sees the shortage coming before it becomes a payroll problem.

THE DEFINITION

WHAT IT MEANS.

Construction cash flow problems are timing problems: the distance between when a job spends cash and when that cash gets collected, left unmanaged across every job active at once.

THE THREE CAUSES

WHY THE CASH GOES SHORT.

01

Cause 01, billing lag: the distance between cost and cash

Every job has distance between when cost is incurred, meaning mobilization, materials, and labor, and when that cost gets billed and collected. On most commercial subcontractor work that is 30 to 90 days depending on the GC or owner, and it repeats on every job active at the same time. The distance itself isn't the problem. Not knowing how wide it is, or funding it reactively off a line of credit instead of planning for it, is what turns a normal billing cycle into a cash crisis.

02

Cause 02, no rolling cash forecast: reacting instead of planning

Without a rolling cash flow forecast, most owners find out they're tight the week a payroll or a vendor payment is due, not a month ahead when there's still time to do something about it. A 13 week rolling forecast turns that discovery into a planned event. The squeeze still exists, but it's visible weeks out instead of surfacing as a surprise on a Thursday afternoon.

03

Cause 03, job profitability tracked at closeout: too late to act on it

When actual cost is only compared to the bid at the end of a job, labor variance, unbilled change orders, and overhead misallocation compound for the whole duration before anybody sees the number. Weekly cost to complete tracking catches the same variance while there's still time to correct staffing, billing, or scope, instead of finding it in a closeout report with nothing left to do about it.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because profit and cash timing are different things. Billing lag, no rolling cash forecast, and job profitability tracked only at closeout can each drain cash from a genuinely profitable business. The P&L doesn't report the timing problem underneath, because the P&L was never built to be a timing document.

Billing lag, the distance between when cost is incurred and when cash is collected, is the most common cause underneath everything else. It's normal and expected on commercial work, but without a forecast to plan around it, it turns into a recurring crisis.

Build a 13 week rolling cash flow forecast around your actual billing cycles, put a defined AR collection cadence in place, and track job cost variance weekly instead of waiting for closeout. All three together address the causes rather than the symptoms.

Usually not on its own. A larger line can buy breathing room, but without a cash forecast the same billing lag and collection issues will max it out again. The forecast is what turns the line of credit back into a temporary bridge instead of a permanent balance.
