A general contractor recently closed his best year ever. Revenue was up over 30%. Two major commercial projects were completed, a full crew was hired, and a healthy backlog of work was lined up heading into spring. On paper, the business was thriving.
But he was borrowing money to make payroll.
This is one of the most common and most dangerous patterns in the construction industry. A contractor can be profitable, busy, and growing — and still be weeks away from a cash crisis at any given moment. It’s not a sign of bad management. It’s a structural reality of how construction businesses operate, and it catches even experienced operators off guard.
This post breaks down why cash flow works differently in construction than in most other industries, and what contractors can do about it before the busy season makes it worse.
Why Construction Cash Flow Is Uniquely Difficult
Most businesses sell a product or service, collect payment within 15 to 30 days, and use that cash to fund the next round of operations. The cycle is relatively short and predictable.
Construction doesn’t work that way. The cash cycle is long, lumpy, and full of timing mismatches. Here’s what makes it different:
Money goes out before it comes in. Materials, labor, equipment rentals, and subcontractor deposits all happen before the first draw request is submitted. On a large project, a contractor might be $50,000 to $200,000 into the job before seeing a dollar back.
Draw schedules create built-in delays. Even when work is complete, there are inspections, approvals, and processing to get through. A 30-day net payment from the general contractor or project owner is optimistic. 45 to 60 days is common. 90 days isn’t rare.
Retainage holds back the profit. On most commercial projects, 5% to 10% of each payment is withheld as retainage until the project is substantially complete. That means the margin earned on paper isn’t cash that can be spent — sometimes for months or even over a year.
Seasonal swings compound everything. In regions like Arkansas, spring through fall is when most work happens. Contractors staff up, take on overhead, and commit to jobs. But the cash from those jobs may not fully land until well into the slower winter months.
The Profit-Cash Disconnect: A Real Example
The gap between profit and cash is one of the most misunderstood dynamics in construction — and in business generally. As explored in Cash Flow vs. Profit: Why Both Matter for Growth, a business can show strong net income on paper while struggling with liquidity. In construction, this disconnect is amplified by the structure of every single project.
Consider a subcontractor who wins a $500,000 commercial project with a 15% gross margin. On the P&L, that’s $75,000 in gross profit. It looks great.
But here’s what the cash flow actually looks like:
- Month 1: $80,000 goes out for materials and labor mobilization before the first draw is even submitted.
- Month 2: The draw is submitted but takes 45 days to process. Meanwhile, another $60,000 is spent to keep the project moving.
- Month 3: The first payment of $120,000 arrives, but $12,000 is withheld as retainage. The business has received $108,000 against $140,000 already spent.
- Months 4–6: The pattern continues. Cash arrives behind the spend, and retainage keeps accumulating.
By the time the project is done, the P&L shows $75,000 in profit. But the contractor was cash-negative for most of the job. Running two or three projects simultaneously — which most growing contractors do — multiplies the gap significantly.
This is how profitable contractors run out of money.
What Contractors Can Do About it
The good news is that cash flow problems in construction are manageable — with the right tracking and planning. Here are five strategies that make a measurable difference:
- Track Cash Flow by Project, Not Just Overall
Most contractors look at their bank balance as one number. That’s like checking the fuel gauge for an entire fleet by averaging — one truck might be running on empty while another has a full tank. Knowing which projects are generating cash and which ones are consuming it is essential. This requires clean, accurate books at the project level, something discussed in depth in How to Read Your Financial Statements (And Why Most Business Owners Don’t Bother). Job costing isn’t optional in construction. It’s a survival tool.
- Build a Cash Flow Forecast, Not Just a Budget
A budget shows what a business plans to spend. A cash flow forecast shows when money comes in and when it goes out. In construction, the “when” matters as much as the “how much.” A rolling 13-week cash forecast that maps expected draws against committed spend doesn’t have to be sophisticated — it just has to exist. As outlined in Why Financial Forecasting Is the Secret to Long-Term Growth, forecasts built on real data become genuine planning instruments rather than guesswork.
- Negotiate Payment Terms Aggressively
Many contractors accept whatever payment terms the GC or project owner dictates without pushing back. But terms are often negotiable, especially for reliable subs. Shorter draw cycles, reduced retainage percentages, and front-loaded mobilization payments are all worth asking for. Every day shaved off the payment cycle is a day of cash that doesn’t have to be floated out of pocket.
- Establisha Line of Credit Before It’s Needed
The worst time to apply for a credit line is when cash is already short. Banks want to lend to businesses that don’t desperately need the money. Setting up a revolving line of credit during a strong quarter, with clean financials and a clear track record, means it’s there when a project cash gap hits. Clean financial reporting isn’t just a tax season requirement — as covered in Why Clean Financial Reporting Is the Foundation of Smart Tax Planning, it’s what makes the numbers trustworthy enough for banks, bonding companies, and investors to act on.
- Watch Retainage Like a Hawk
Retainage receivables can add up to staggering amounts across multiple projects. It’s not uncommon for contractors to have $200,000 or more locked up in retainage they aren’t actively tracking. Creating a retainage aging report, knowing when each amount becomes collectible, and following up the moment it’s due are critical disciplines. That money has been earned — it shouldn’t sit on someone else’s books any longer than necessary.
Why Spring is the Most Dangerous Time
For contractors reading this in April, the timing matters. Spring is when construction activity ramps up across Arkansas and the broader region. Crews are being hired, materials are being ordered, subcontractors are being committed, and new jobs are being mobilized.
All of that is cash going out the door — before the first draw comes in. For contractors scaling up from last year, the gap is even wider because commitments are larger than they’ve ever been while cash reserves are based on last year’s volume.
This is the exact moment to get a cash flow forecast in place. Not after things are already stretched thin.
Building a Business That’s Profitable and Liquid
Profit matters. But in construction, cash is what keeps the lights on, the crew paid, and the projects moving. The most resilient contractors aren’t necessarily the ones with the highest margins — they’re the ones who understand their cash cycle well enough to never get caught off guard.
That takes discipline, the right reporting, and a financial partner who understands the unique rhythm of how construction businesses operate. Empyrean Financial CPAs works with contractors across the region because the difference between a P&L problem and a cash flow problem matters — and in this industry, the solution is almost never the same.
