Construction businesses are profitable on paper and cash-starved in practice. Contractors front labor and materials, bill in progress draws, and wait — often 30 to 90 days — while a percentage is held back as retainage. Financing in this industry is mostly about covering the gap between when money goes out and when it comes in.
The progress-billing and retainage gap
On most commercial jobs, a contractor performs work, submits a pay application, and waits for the general contractor or owner to approve and remit. Retainage — commonly 5–10% — is withheld until the project is substantially complete, which can be months after the work is done.
That structure means a growing, profitable contractor can run out of cash precisely because it is winning more work. The financing question is rarely 'is the company healthy' and usually 'how do we fund payroll and materials until the draw clears.'
Equipment financing
Excavators, loaders, trucks, and trailers are natural candidates for equipment financing because the asset secures the loan. This preserves working capital and a line of credit for labor and materials, where there is no collateral to pledge.
For a fleet or a single high-value machine, compare equipment financing against an SBA 7(a) facility. Equipment lenders can be faster and more asset-focused; SBA can offer longer terms. The right answer depends on how long the machine stays productive relative to the loan term.
Lines of credit and mobilization funding
A revolving line of credit is the workhorse for contractors: draw to mobilize a job and make payroll, repay when the progress draw lands, and repeat. Because usage is uneven, paying interest only on the drawn balance fits the cash-flow pattern well.
Some contractors also use invoice or receivables financing against approved pay applications to accelerate cash. This is distinct from surety bonding, which guarantees performance to the project owner and is not a source of operating cash — owners sometimes conflate the two.
What lenders look at
Lenders review the work-in-progress (WIP) schedule, backlog, aging of receivables, and concentration risk — how dependent the company is on one general contractor or one project. A diversified backlog with clean receivables reads as lower risk.
Personal credit, time in business, and existing equipment debt all factor in. Contractors who keep job-costing and WIP reporting current tend to qualify for better structures because the lender can actually see how each project is performing.
