GROWTH AND CASH FLOW

CASH FLOW WHEN GROWING FAST.

QUICK ANSWER

Growth is supposed to mean more money, and in construction it creates a cash crisis first. More jobs means more mobilization cost, more pay when paid exposure, more receivables outstanding at the same time, and more overhead, all of it before any of the new revenue has been collected. The benchmark is 10 to 15 percent of annual revenue held in working capital, so moving from $3M to $6M takes the target from roughly $300K to $450K up to $600K to $900K.

What catches good contractors is that none of this looks like a problem while it's happening. The backlog is the best it has ever been, the crews are busy, and every job in the file is priced to make money. Underneath that, three jobs bought material, staged crews, and pulled permits in the same month, and not one of them can bill for another thirty days. Cash leaves the building on a schedule the field controls and comes back on a schedule the GC controls. That timing difference is the entire problem, and it has nothing to do with whether the work is profitable.

THE DEFINITION

WHAT IT MEANS.

The construction growth paradox is what happens when revenue growth front loads cost before the collections catch up, so the bank account tightens in the same quarter the backlog looks best.

Growth changes the timing of money before it changes the amount. A new job spends on mobilization in week one, can't bill for it until the first pay app, then waits out the GC's pay cycle and a retainage hold on top of that. Run that sequence on one job at a time and the business absorbs it without anybody noticing. Run it on three jobs at once and the same sequence empties the account.

WHAT WE SEE IN THIS BUSINESS

WHERE THE GROWTH EATS THE CASH.

01

Revenue growing but cash tightening

You're winning more work than ever and the backlog looks great, but the bank account is getting tighter instead of looser. This is the construction growth paradox: revenue growth front loads cost before any of the collections come in. The faster you grow, the wider the distance between what you're spending and what you're collecting.

02

Multiple simultaneous mobilizations draining cash

Every new project starts with mobilization cost. Equipment gets deployed, material gets bought, permits get pulled, and crews get staged, all of it before the first pay app can even be submitted, let alone collected. When two or three projects mobilize in the same month, the combined mobilization drain can exceed your entire working capital reserve.

03

Growing beyond working capital

Working capital requirements climb with revenue, because larger projects want more money up front, pay when paid cycles run longer, and retainage holds get bigger in dollar terms. A working capital base that was adequate at $3M can be critically thin at $6M. Growing into a working capital crisis is one of the most common ways construction businesses fail during their best year.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The working capital target as you scale

The benchmark is 10 to 15 percent of annual revenue held in working capital. At $3M of revenue that's roughly $300K to $450K, and at $6M it's $600K to $900K, so doubling revenue roughly doubles the target. If you plan to double revenue without doubling working capital, you need either a larger credit facility or a longer runway on project start sequencing to bridge the difference.

HOW SPM FIXES IT

HOW GROWTH GETS FUNDED.

A 13 week cash flow forecast built for the growth period

The most useful tool during fast growth is a 13 week cash flow forecast that models every new project's mobilization timeline and collection schedule at the same time. When you can see 90 days out that three simultaneous mobilizations will drain week 6, you still have time to stage the starts differently, restructure a pay app, or draw on the line. Finding out in week 6 leaves you with none of those choices.

A working capital target that scales with revenue

As revenue grows the working capital requirement grows with it, so the target gets recalculated rather than left where it was two years ago. We track the working capital position monthly and advise on distribution policy against it. That way the balance builds alongside the revenue instead of getting drawn out of the business in the same year the business needs it most.

Backlog and mobilization sequencing

During fast growth, when the jobs start counts as much as how much backlog you're holding. Three projects starting the same week can be unaffordable even when each one prices out fine on its own. We model the cash impact of a proposed start before you accept it, so the growth is funded rather than just signed.

COMMON QUESTIONS

FREQUENTLY ASKED.

As a general benchmark, working capital of 10 to 15 percent of revenue means doubling revenue requires roughly doubling working capital. Going from $3M to $6M revenue moves your working capital target from approximately $300K to $450K up to $600K to $900K. If you're trying to double revenue without doubling working capital, you'll need a larger credit facility or a longer project start sequencing runway to bridge the difference.
Sometimes, and it's a legitimate strategic decision rather than a failure. Taking on more work than your working capital can carry sets up a cash crisis at the moment everything looks best, which is the worst time to be surprised. We work out the revenue growth rate your current working capital can sustain, and what has to improve financially before the next level of growth is safe to take on.
