Working capital for construction companies

Construction companies run short of cash for one reason above the others: payroll and materials are paid every week, while progress payments arrive monthly, often on 30- to 90-day terms, with retainage held back until the job closes. The usual answers are a line of credit sized to that gap, financing against billed work, and equipment finance for machines, with a short-term advance kept for the gaps the others do not cover.

Why cash runs short when work is good

A growing contractor can be profitable and still short of cash. Each new job needs labor and materials before the first pay application is approved, and retainage, commonly 5 to 10 percent of each payment, is held until completion. The more work a company wins, the more of its money sits in jobs that have not paid yet. Most financing for contractors is financing for that timing.

A line of credit for payroll between draws

A revolving line is the closest fit. It is drawn when payroll comes due and paid down when the draw arrives, and interest is charged only on what is used. Banks offer lines to contractors with two or more years of financial statements; online lenders offer smaller lines with less paperwork, at a higher cost.

Financing billed work

When a pay application has been approved but not yet paid, receivables financing advances against it. Construction receivables are harder to finance than most, because of retainage, lien rights and the chance of a dispute, so fewer funders do it. Those that do will want the contract, the pay applications and the paying party's history.

Equipment

Excavators, loaders, trucks and lifts are financed against their own value, over terms that commonly run three to seven years. Refinancing machines the company already owns outright can also release cash for working capital.

Short-term working capital

A revenue-based advance funds within days and is repaid from deposits. It costs more than a line, so it should cover a specific gap, such as mobilizing a new job, rather than serve as standing finance.

What helps a file

  • Three to six months of business bank statements
  • A list of current jobs with contract values, amounts billed and amounts paid
  • Receivables aging, including retainage
  • For larger requests, the last two years of financial statements or tax returns

Questions owners ask

How do contractors get funding when clients pay net 60 or net 90?
Most use a revolving line of credit, financing against approved pay applications, or both. The line covers payroll and materials as they come due; receivables financing turns billed work into cash before the client pays.
Can a contractor borrow against retainage?
Some funders will advance against retainage, at a lower percentage than against current receivables, because it is paid only when the job closes and the work is accepted.
What do lenders look for in a construction company?
Steady deposits, a backlog of signed work, how much revenue depends on the largest clients, and a record of jobs completed and paid. For larger amounts, financial statements and a list of jobs in progress.
Is an SBA loan an option for a contractor?
Yes. SBA 7(a) loans, and the SBA's CAPLines program, which includes lines tied to specific contracts, can fund working capital at a lower cost. They take several weeks to close and need more documentation.
