One of the most dangerous misconceptions in the construction world is that a healthy Profit and Loss (P&L) statement equals a healthy business. At Miller Advisory Co., we often meet with business owners who have a massive backlog of work and high projected profits, yet they are struggling to meet payroll or pay their vendors on time.
The reality? You don’t go out of business because of a lack of profit; you go out of business because of a lack of cash.
In this article, we explore the mechanics of construction cash flow and the strategies we use to help our clients maintain liquidity throughout the project lifecycle.
The “Cash Gap” in the Construction Lifecycle
Construction is unique because it is one of the few industries where the contractor often acts as a bank for the client. You pay for labor every week. You pay for materials (often within 30 days). However, you might not receive payment from the owner or general contractor for 45, 60, or even 90 days.
This is known as the Cash Gap. As your company grows and you take on larger projects, this gap widens. If you don’t have a strategy to bridge it, “success” can actually lead to bankruptcy.
1. The Trap of Under-Billing (and the Power of the Schedule of Values)
One of the primary causes of a cash crunch is under-billing. This happens when the value of the work performed is greater than the amount you have actually invoiced.
The Leak: Many contractors are “nice guys.” They wait until the end of the month to tally up their costs and send an invoice. By the time that invoice is processed and paid, the contractor has been “loaning” the client money for six weeks.
The Miller Advisory Solution: We help our clients front-load their Schedule of Values (SOV). By legally and ethically allocating more value to the mobilization and early-stage tasks (like site prep or submittals), you can get more cash into the business at the start of the project. This “positive cash position” ensures you aren’t dipping into your lines of credit just to get a project off the ground.
2. Managing “Retainage” Without Suffocating
Retainage—the practice of a client withholding 5% to 10% of every payment until the very end of the project—is a standard industry practice, but it is a silent killer of liquidity.
The Leak: In many cases, your entire profit margin is tied up in the retainage. If a project lasts 12 months, you won’t see your profit until month 14 or 15. If you have multiple projects hitting “close-out” at the same time, your cash can be locked away exactly when you need it for the next big mobilization.
The Miller Advisory Solution: We consult with our clients on Retainage Management Strategies. This includes negotiating “reduction of retainage” clauses in contracts (e.g., reducing retainage from 10% to 5% once the project is 50% complete) and ensuring that “Punch List” items are completed with lightning speed to trigger final payments.
3. The Dangers of “Over-Trading”
Over-trading occurs when a business takes on more work than its working capital can support. It’s a “growth trap.” You win three big bids in one month, but you don’t have the cash to pay for the initial material deposits or the surge in payroll.
The Leak: To cover the new jobs, owners often start using the “deposit” from Job B to pay for the “labor” on Job A. This is the beginning of a dangerous cycle that eventually collapses.
The Miller Advisory Solution: We implement Cash Flow Forecasting Models. Before you sign a new contract, we help you run a “Stress Test” on your cash flow. We look at your current liquidity and project exactly how much cash will be required to float the new project for the first 90 days. If the math doesn’t work, we help you secure the right kind of financing or renegotiate payment terms with the client before the contract is signed.
Conclusion: Building a “Cash-First” Culture
At Miller Advisory Group, our goal is to turn the “Cash-to-Cash Cycle” in your favor. We move our clients from a defensive position (waiting for checks) to an offensive position (controlling the flow of capital).
When you control your cash, you control your destiny. You can negotiate better prices with vendors by paying early, you can hire the best talent because they know their checks will never bounce, and you can sleep better knowing the foundation of your business is as solid as the concrete you pour.
