Winning work is usually treated as an unquestionably positive result for a construction business. A growing order book provides revenue visibility, supports investment and creates confidence about the future. But there is an important distinction: Winning more work and becoming financially stronger are not necessarily the same thing. For a growing contractor, a significant increase in workload can place enormous pressure on cash, people, systems and the balance sheet. The issue isn't whether growth is good or bad. It is whether the business has the financial capacity to fund and manage the growth it is taking on.

Every new project needs to be funded Construction businesses generally incur costs before they receive the corresponding cash from customers. A new project might require:

  • mobilisation
  • additional employees
  • subcontractors
  • materials
  • plant and equipment
  • insurance and bonds
  • site establishment
  • additional overhead.

Many of those costs occur before the first meaningful customer payment is received. That creates a funding gap. Consider a contractor currently delivering $30 million of work each year. It wins several projects and expects revenue to increase to $45 million. Commercially, that looks like excellent growth.

But the additional $15 million of activity must be delivered before all of the associated cash is collected. If the business effectively funds even one month of that additional activity, the increase in working capital can quickly run into seven figures. The projects can all be profitable and the business can still experience significant cash pressure.

The order book doesn't fund the business A strong forward order book is valuable. But an order book is not cash. A business can have its strongest order book ever and simultaneously have its weakest short-term liquidity position. This becomes particularly important when several projects commence around the same time. The business may suddenly need to recruit people, mobilise equipment, increase supplier purchases, engage additional subcontractors and expand corporate support functions. Cash leaves the business before much of the associated project cash arrives. That means management needs to understand not only: "How much work have we won?" but also: "What will it take to fund the delivery of that work?" Those questions should be considered together.

The speed of growth matters Two businesses can grow by exactly the same amount and experience very different levels of financial pressure. A contractor growing from $30 million to $45 million over three years has considerably more time to build its finance team, systems, working capital and management capability. A contractor making the same jump in twelve months faces a different challenge. The faster the growth, the more pressure it places on the existing business simultaneously. Working capital requirements increase. More people need to be recruited. Management spans increase. Systems process more transactions. Commercial teams oversee more contracts. Project managers control more money. Finance needs to produce increasingly sophisticated information.

The business isn't simply becoming larger. It is becoming more complex. And complexity often grows faster than revenue.

Growth can expose weaknesses that were already there A $15 million contractor can operate successfully with processes that become inadequate at $40 million. That doesn't necessarily mean those processes were wrong. They may simply have reached their limit. A spreadsheet-based project forecast might work when management oversees five projects. It may become difficult to control when there are twenty. A founder approving most significant expenditure may work with a small management team. It can become a bottleneck as the organisation grows. An informal monthly project review may work when senior management knows every project intimately. It becomes increasingly risky when responsibility is delegated across multiple project teams. Growth has a habit of exposing these limitations quickly. The danger is assuming that because a system successfully supported the business yesterday, it will necessarily support the business tomorrow.

More work can hide underperformance Rapid growth can also make financial performance more difficult to interpret. New projects contribute additional revenue and gross profit. That can mask deterioration elsewhere in the portfolio. A poorly performing project may appear less significant when consolidated revenue is increasing strongly. Corporate overhead can increase without attracting attention because overall gross profit dollars are rising. Cash pressure may be attributed to growth rather than underlying project issues. This is why management should be cautious about relying on headline measures such as: Revenue is up. EBITDA is up. The order book is at record levels. All three can be true while the risk profile of the business is deteriorating. The more useful questions are:

Are margins holding? Is operating cash converting consistently from profit? Is working capital increasing proportionately with growth? Are project forecasts reliable? Is overhead growing faster than gross profit? Do we have enough financial capacity to deliver the forward order book?

Growth can change the risk carried by the balance sheet Larger projects often bring larger financial exposures. A growing contractor may need greater bank guarantee facilities, higher insurance limits, more working capital and increased equipment financing. Customer concentration can also increase. Winning a $20 million project may be transformational for a $30 million business. But it also creates significant exposure to the commercial performance and payment behaviour of one project and one customer. Management therefore needs to consider the balance sheet alongside the pipeline. A project isn't attractive simply because it generates revenue and margin. The business must also understand: How much cash will this project consume? What security or guarantees will it require? What is our downside if the project underperforms? How long will our capital remain tied up? What happens if the customer pays 30 days later than expected? That is particularly important when several large projects are won simultaneously.

Not all growth is equally valuable Revenue growth is easy to celebrate. Quality growth requires more scrutiny. A project generating a strong accounting margin but requiring substantial working capital, significant guarantees and a high level of commercial risk may be less attractive than its headline margin suggests. Similarly, a customer offering large volumes of work but consistently paying slowly may create more strain than value. As businesses mature, management should become increasingly selective about the work it takes on.

The question evolves from: "Can we win this project?" to: "Should we win this project?" That requires understanding return, risk and cash together.

Warning signs that growth is getting ahead of the business Rapid growth deserves closer attention when:

  • cash requirements repeatedly exceed forecasts
  • debt facilities are increasingly used to fund normal operations
  • debtor and WIP balances are growing faster than revenue
  • project forecasts are late or unreliable
  • unapproved variations are accumulating
  • finance and commercial teams are constantly reacting rather than looking forward
  • management reporting arrives too late to influence outcomes
  • project managers are stretched across too much work
  • corporate overhead is increasing faster than expected
  • guarantee or bonding capacity is becoming constrained
  • management is winning work without modelling the associated working-capital requirement.

None of these automatically means the business should stop growing. They mean the financial infrastructure supporting the growth needs attention.

Forecast the business you are becoming One of the most useful exercises for a rapidly growing contractor is to stop looking only at today's business. Instead, model what the organisation looks like after the current order book has been mobilised. If revenue increases substantially over the next twelve months: What happens to debtors? What happens to WIP? What happens to retentions? How much additional cash is required? What happens to bank guarantee requirements? How many additional people are needed? What corporate overhead needs to be added? What systems and controls need to change? What happens if margins are 2% lower than forecast?

What happens if customers pay ten days later? This converts growth from an ambition into a financial plan. And it gives management time to solve problems before they become urgent.

The objective isn't slower growth. It is sustainable growth. A strong order book is one of the best positions a contractor can have. The mistake is assuming that the order book itself makes the business financially secure. Growth needs to be funded. It needs to be controlled. And it needs management infrastructure capable of supporting a more complex organisation. The businesses that manage growth well aren't necessarily those that win the most work. They are the ones that understand how much growth they can safely absorb, what resources that growth requires and what risks they are taking onto the balance sheet. The question therefore isn't simply: "How much work can we win?" A better question is: "How much work can we successfully deliver without putting the financial strength of the business at risk?"

Salt Strategic Advisory works with growing construction, infrastructure and project-based businesses to strengthen financial visibility, project forecasting, cash flow and commercial decision-making. If your order book is growing rapidly, understanding the financial capacity required to deliver it can be just as important as understanding the margin in the work you've won.
