CONCRETE PUMPING JOBS LOOK PROFITABLE. THE CASH IS STILL IN TRANSIT.
Concrete Pumping subcontractors run out of cash for reasons specific to how the work is built and billed, on jobs that are making money. The three that cost the most in this trade are below, taken from concrete pumping contractor research. Most sit at 75 to 90 days from finishing work to holding the money, and 45 days is achievable.
Cash and profit are measured on different clocks. Your profit and loss records revenue when you invoice and costs when you incur them, while the bank account only knows what cleared. Labour goes out weekly and collects 45 to 90 days later, minus retention. That distance is what a growing, profitable concrete pumping company funds out of pocket, and it widens as you grow. The specific things that widen it in this trade are what the rest of this page is about.
WHERE IT LEAKS OUT.
The pump waits on everyone: late ready-mix trucks, gaps between loads, finishers pacing the placement, a missed street-staging window. Published planning explicitly budgets it (standby at $125 to $200 per hour, 1 to 2 hours carried where schedule risk exists; a 45-minute-late first truck in a staged urban pour "can burn an hour of chargeable standby and potentially trigger a re-setup"). Standby is either the trade's best-margin hour or its purest donation, decided entirely by whether the rate sheet names it and the operator logs it.
The dispatchable unit is an operator with a certified machine: operator pay published at $40,000 to $60,000 with training/certification requirements, insurance at $5,000 to $15,000 annually, and the boom itself a six-to-seven-figure asset on a maintenance clock. Utilization per unit (pours per truck-week against ownership carry) is the fleet's version of the scaffolding yard math, and a parked boom is the most expensive silence in the concrete family.
WHAT MOVES MARGIN IN THIS TRADE.
The Minimum Sold Twice
The 3-to-4-hour minimum is the unit of capacity, and dispatch density (how many minimums a truck stacks in a day against drive time) is the P&L. A truck-day report by dispatch is the trade's core statement.
The Clock That Waits
Late ready-mix, slow finishers, and missed staging windows run the pump's meter only if the rate sheet names standby and the ticket logs the cause. Waiting is the best-margin hour or the purest donation; the paper decides.
The Parked Boom
The capacity unit is a certified operator on a six-figure machine carrying insurance and maintenance whether it pumps or not. Per-truck utilization against ownership carry is the fleet decision that precedes every quote. (cfos-working-capital-system) ---
DAYS SALES OUTSTANDING.
Ninety days is weak, 45 is the target, 30 is strong. Nothing else moves cash faster.
| Position | Days | What it means |
|---|---|---|
| Weak | 90 days | Roughly three months of work funded out of your own pocket. |
| Target | 45 days | Achievable on the days you control: submission timing, complete documentation, follow up in week two. |
| Strong | 30 days | Requires discipline every month, and it's the cheapest capital available to you. |
Moving from 90 days to 45 frees roughly annual revenue divided by 365, times 45 days. At $4M that's about $493,000. At $8M it's about $986,000. That money doesn't come from a bank and it costs no interest, which is why we work the cycle before discussing financing anything.
CONCRETE PUMPING BENCHMARKS.
Concrete Pumping subcontractors at $1M to $5M net 7 percent, against a CFOS target of 10 percent, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. Working capital should sit at 13 percent of annual revenue, and the monthly close should finish by day 10 so the numbers can still change a decision.
