How Contractors Can Stop Living Deal to Deal: Working Capital Between Jobs

Cash flow is the defining challenge of the construction business. Not revenue — cash flow. A contractor can have $2 million in active contracts and still not be able to make payroll this week, because the draws are delayed, the retainage is held, and the GC is 45 days behind on payment. This isn't a sign of a failing business. It's the structural reality of how construction gets paid — and it's why the financing tools designed for other industries often don't fit contractors the way they should.

Why Banks Misread Contractor Cash Flow

A conventional lender looking at a contractor's bank statements often sees what looks like an erratic picture: large deposits when draws come in, stretches of lower activity between them, high expenses clustered around project starts. The account swings. To an underwriter without context, this pattern can look like instability. To anyone who understands the industry, it's exactly what a healthy, active contractor looks like.

The problem is that most loan officers — particularly at community banks and SBA lenders who don't specialize in construction — don't adjust for this. They apply the same banking health filters they'd apply to a retail business with daily sales, and the contractor who's doing $1.5 million in annual volume gets assessed as if the irregular deposits are a weakness rather than a structural feature of the industry.

This is one of the primary reasons contractors are underserved by conventional lending despite often having strong fundamentals. Knowing how to tell that story — and which lenders actually understand it — is part of what good positioning looks like.

The Real Cash Flow Problem: Draws, Retainage, and Mobilization

Draws are progress payments released at specific project milestones. You do the work, you submit a draw request, you wait for the GC or owner to approve and release payment. That process takes time — sometimes two to four weeks after the milestone. Meanwhile, the labor and materials were paid before the draw was even submitted.

Retainage is the percentage of each draw held back until project completion — typically 5 to 10% of the contract value. On a $400,000 contract, $40,000 might be held in retainage throughout the job and released only after final acceptance. That capital is earned but inaccessible until the very end of a project cycle that may span months.

Mobilization is the capital required to get a new contract started — materials, equipment, labor, insurance — before the first draw is available. A contractor who lands a new contract on Thursday may need $30,000 on Monday before any revenue from that contract has been received.

Together, these create a consistent gap: work happens, money comes later. The business needs capital in between.

Products That Actually Work for Contractors

Working capital advances are the most immediate solution for mobilization and short-term gaps. Because they underwrite on banking history rather than project cash flow, they're accessible to contractors whose tax returns show lower net income than their actual business activity. The tradeoff is the higher cost — which is most justified when the capital directly enables a contract that generates more than it costs. Some contractors also build the cost of financing into their project pricing, effectively deferring it to the client through the contract margin. That's a legitimate approach, but progress billing — structuring your draw schedule to match your actual cost timeline — is worth getting right first. When payroll and materials need to move before a draw clears, an advance or line of credit is usually the most efficient tool.

Business lines of credit are worth pursuing if you qualify. A revolving line lets you draw what you need for a specific job, pay it back as draws come in, and use it again on the next contract — without taking on a lump-sum advance every time. The qualification bar is higher (lenders typically want two years of business history and clean banking), but for established contractors with a consistent revenue track record, a line of credit is often the most cost-effective way to manage mobilization and timing gaps on a recurring basis.

Invoice factoring and AR financing are worth understanding for contractors with a strong commercial client base. If you have unpaid invoices from creditworthy GCs or municipal clients, factoring lets you access those funds immediately — typically 80 to 90% of the invoice value — while the factoring company waits for payment. The cost is a fee on the advance, and it's often significantly lower than a revenue-based advance for contractors whose customer credit is strong.

Equipment financing is well-suited to contractors. Construction equipment is identifiable collateral with clear value, which makes this product accessible at much lower rates than unsecured working capital. If you're currently leasing equipment, it's worth comparing — in many cases, financing the purchase outright is cheaper over the long run than ongoing lease payments, and you end up owning an asset. If aging equipment is slowing production or creating expensive downtime, financing it may address two problems at once.

SBA 7(a) is available to licensed general contractors and many specialty subcontractors — but not to all construction businesses. Real estate developers and property flippers generally don't qualify, because the underlying income is speculative and tied to a sale event rather than operating cash flow from an ongoing business. SBA is designed for service and trade contractors with recurring project revenue. The additional challenge for contractors is documentation — construction income is project-based, creating the irregular banking picture lenders struggle with. The right SBA lender is one who actually understands the industry and won't apply retail-business logic to a project-based income structure.

Using Capital Strategically in Construction

The contractors who use working capital well treat it as a project-specific tool, not a general business lifeline. The math that justifies a working capital advance in construction: the contract value net of all project costs, divided by the cost of capital. If a $75,000 contract generates $20,000 in margin and the advance to fund mobilization costs $4,000 in total, that's a sound decision. If the margin is thin and the advance makes the project break-even or worse, it isn't.

The contractors who end up with compounding financing problems are usually ones who use working capital to cover overhead between projects rather than to fund specific project capital. The distinction matters: one is deploying capital that generates a return, the other is borrowing to survive a gap with no clear end date.

The Path to Better Terms

Most contractors start with working capital because it's accessible. The trajectory toward better terms — lower rates, longer repayment windows, larger amounts — runs through three things: two years of filed tax returns showing real income, a banking history that underwriters can follow (consistent deposits, no chronic NSFs, clear separation between business and personal finances), and reduced reliance on advance positions. Contractors who are intentional about building that profile have a clear path to SBA or commercial line of credit financing within 18 to 24 months.
