Business loans for contractors: why the cash runs short
A general contractor or framing crew is usually out of pocket before the first draw arrives. Materials get ordered, the crew works two or three pay periods, and the builder or owner pays only after an inspection or a pay application is approved. Then retainage holds back part of each payment until closeout.
None of that means the business is unprofitable. It means the business is financing its customers. Working capital for a construction company exists to carry that timing gap without stalling the next job.
What is retainage in construction billing?
Retainage is the share of each progress payment the owner or general contractor holds back until the work is complete and accepted. On a long job, retainage can add up to a large receivable that sits on the books for months. Partners reviewing a contractor's request often ask how much retainage is outstanding and when it is expected to be released.
How to calculate the working capital requirement for a construction company
A simple way is to map one job's cash out and cash in week by week. Add the materials paid before the first draw, the payroll for every week until that draw clears, and equipment and insurance costs for the same stretch. Subtract each draw as it lands, net of retainage. The deepest point on that curve is the working capital the job needs. Do it for overlapping jobs and the requirement becomes clear.
Partners do not use one formula, but a request that shows this curve, with the contracts behind it, is easier to review than a round number.
Contractor bills paired with funding shapes
| Need | Funding shape | Why it fits |
|---|---|---|
| Crew payroll between draws | Working capital | Short, defined gap with a draw as the repayment source |
| Materials for several jobs at once | Line of credit | Draw per job, repay as each is paid |
| Skid steer, trailer, work truck | Equipment financing | The machine secures the funding |
| New shop or yard, or buying a competitor | Term loan | One planned project, fixed payments |

A labeled example (invented figures, not an offer)
A residential framing company in Florence, AZ takes a $180,000 contract with draws at three stages. Before the first draw it spends $22,000 on lumber and fasteners and runs three weekly payrolls of $8,000. Each draw is paid net of a 10% retainage. The deepest cash gap, just before draw one clears, is about $46,000. A working capital request sized to that gap, with the contract attached, is concrete. The partner would set any amount and terms.
