How Money Moves Through a Building Contractor
A contractor spends first and collects later. Lumber, concrete and fixtures are bought at the start of each phase; subcontractors and crews are paid weekly or biweekly; the owner or lender pays a draw only after work is inspected. On top of that, some contracts hold back a portion of each payment as retainage until the job is complete.
The result is that a profitable contractor can be short of cash in the middle of every job. What is a contractor's loan, in practice? It can be a combination of products rather than one: a revolving line for the draw gaps, working capital for a large job's front-end costs, and equipment financing for the machines.
Contractor Financing Options Compared
| Need | Structure | Why it fits |
|---|---|---|
| Lumber, labor and subs while a draw is pending | Line of credit | Draw per phase, repay when the draw clears, reuse |
| Front-end costs of one large job | Working capital | One sum repaid on a fixed schedule over the job's life |
| Track loader, mini excavator, dump trailer, pickup | Equipment financing | Secured by the machine; term tracks its working life |
| Retainage held until completion | Line of credit | Covers the held-back share until final payment |
| Second yard or shop expansion | Term loan | Long-lived improvement repaid over years |
A Construction Line of Credit and Retainage
Retainage is one place contractors feel the squeeze. Illustration only: on a $400,000 contract that holds back 5% of each progress payment, $20,000 stays with the owner until closeout, even though the contractor has already paid for the labor and materials it represents. Multiply that by four or five open jobs and a meaningful share of the company's earned money is waiting on punch lists.
A revolving line sized to that held-back total lets the business keep bidding while it waits. The longer explanation, with a worked cash calendar, is in the retainage and cash flow post for Waukesha County, WI contractors.
Construction Equipment Financing
Compact track loaders, mini excavators, dump trailers, lifts and work trucks can be financed as equipment loans, with the machine as collateral. Some partners finance used equipment, with a closer look at hours, condition and seller. Leasing can suit equipment you replace often; buying suits machines you will run for a decade.
Bring the quote or listing with make, model, year and hours to the first call; that single document gives the partner most of what it needs to start the review.
What Partners Usually Review on a Contractor File
- Statements showing each draw coming in and payroll going out
- A work-in-progress schedule of open contracts
- Accounts receivable, including retainage held
- Equipment debt and leases already on the books
- The entity's registration and any trade credentials the work requires
Partners may ask whether the business holds the credentials its work requires. For residential builders, the Wisconsin dwelling contractor certification guide explains why that question comes up and where to check.
