Cash flow for a concrete pumping business: build the two-week buffer

Cash flow kills more concrete pumping businesses than bad pumping ever will. You can be profitable on paper and dead in the bank. The jobs were real, the invoices were sent, the money exists — it just isn't in your account the week the repayment, the wages and the insurance all land at once. Rain doesn't cancel repayments. Slow-paying builders don't pause your payroll.

The week everything lands at once

Every pump owner eventually meets that week. Two rain days wipe the board. A builder who owes five figures goes quiet. The boys still need paying Friday. The finance comes out Monday whether the boom moved or not. Nothing about the business changed — but suddenly you're checking the account before answering the phone.

One story from the Operators Club cash-flow material puts it plainly: a Brisbane operation went up with around $100,000 behind it. Rain hit, work wasn't ready, promised jobs didn't turn into money fast enough — and the line in the sand became $30,000. Not because that number fixed anything. Because it stopped the slide before zero. Every pump business needs that line drawn before the bad month, not during it.

The buffer formula

The formula is dead simple. Add up your weekly operating costs — fuel, yard, running costs. Add weekly labour. Add weekly loan or lease repayments. Multiply the total by two. That's your buffer number: two full weeks of the business running with nothing coming in.

It lives in a separate account. Not the everyday account where it looks spendable. Separate, boring, untouched. Until it's full, spare money goes there first — before the wrap, before the extras, before anything that makes the truck look better instead of making the business harder to kill.

Get the money moving faster

The buffer is defence. The other half is making money arrive faster. Invoice the same day the job finishes — not Sunday night, not end of month. Follow up within 48 hours. Terms agreed before the boom goes up: seven days for proven regulars, cash on completion for new clients until they've earned better. Waiting time starts when you arrive on site, not when the agi finally shows. Mobilisation fees exist — use them.

Some builders will grumble. Good. The ones who respect a properly run business will pay on terms. The ones who won't were always going to make you chase, and now you know early — before they're forty grand deep in your cash flow.

What the buffer actually buys

Here's what nobody tells you: the buffer isn't dead money sitting there doing nothing. It's negotiating power. It's what lets you knock back the skinny job because you don't need it this week. It's what keeps the boys paid and the reputation intact when the sky opens for a fortnight. Desperate businesses take bad work at bad rates. The buffer is how you stop being desperate.

Module 01 is called No One Is Coming To Save You for a reason. No builder pays early to help you out. No bank pauses the repayment because it rained. The buffer is you, saving yourself, in advance.

Two weeks of costs, in a separate account, before anything else gets a dollar. It's the least exciting money you'll ever save — and the only reason plenty of good pump businesses are still standing.
