What is working capital for construction companies?

Working capital is the cash remaining after you subtract your current liabilities (what you owe in the next 12 months) from your current assets (cash, unpaid invoices, inventory). For construction, it's the buffer you need to cover payroll and materials while waiting 30–90 days for clients to pay you.

The Specifics

Working capital follows a straightforward accounting formula:

Working Capital = Current Assets − Current Liabilities

Current assets include cash on hand, accounts receivable (unpaid invoices you've issued), and materials inventory. Current liabilities are obligations due within the next 12 months: payroll accruals, vendor invoices, loan payments, and tax liabilities.

Construction creates a unique cash timing problem. You pay crews and suppliers before clients pay you. According to market research on working capital trends, small and mid-size general contractors typically carry 45–60 days of accounts receivable while managing payables on 15–30 day cycles. That creates a 30–45 day cash gap where crews must be paid before invoice collections arrive.

A healthy construction company maintains liquid reserves equal to 30–60 days of operating expenses to absorb this gap without stalling payroll or material purchases. If you run a $200,000-per-month crew-and-material operation with a 45-day average client payment delay, you need $90,000–$180,000 in immediate working capital just to keep the lights on.

Why Construction Working Capital Differs From Other Industries

• You pay first, get paid later. In retail or SaaS, you collect cash when you deliver. In construction, you deliver materials and labor on credit, then invoice.
• Payment delays cascade. A single delayed invoice forces you to cover payroll out of operating cash or debt. One month of delays can wipe out months of profit.
• Material and labor costs are fixed by contract; revenue timing is not. You cannot negotiate away a crew's wage or a supplier's 14-day net payment term just because your client hasn't paid you yet.
• Seasonal and project-based gaps compound. Winter slowdowns, project lulls between bids, and uneven work schedules create periods where revenue stops but payroll doesn't.

Working capital loan markets continue to expand, driven largely by construction, staffing, and manufacturing firms needing faster access to cash than traditional banks provide. The faster you can close the gap between paying out and getting paid in, the more cash stays in your business instead of in lender fees.

How Working Capital Loans Work

A working capital loan is a fixed lump-sum advance (e.g., $50,000) that you draw once and repay over a fixed term (typically 3–24 months). Unlike a line of credit, you don't draw and repay repeatedly; you get the full amount upfront and build a fixed payment schedule.

As of July 2026, through our funding partner, working capital loans are available in amounts $10K–$500K at factor rates of 1.15–1.40 (equivalent to roughly 25–60%+ APR depending on term length). Funding closes as fast as 24 hours for pre-qualified applicants.

Most working capital lenders require:

• Minimum credit score: 550 FICO
• Time in business: 6 months minimum
• Monthly revenue: $10,000+/month
• Debt-to-income: Total monthly debt payments should not exceed 12% of gross monthly revenue

You'll need to submit 2–3 months of bank statements (to verify monthly revenue) and, for most lenders, recent tax returns or a current profit-and-loss statement. The underwriting process takes 1–2 business days for a pre-qualified file.

Qualification & Edge Cases

If you have credit under 550: You may still qualify for business term loans (minimum 600 FICO) or invoice factoring (no credit minimum), but working capital will likely be out of reach. Invoice factoring may be your fastest option if you have unpaid B2B invoices.

If you've been in business less than 6 months: Working capital loans require 6 months minimum. Consider a business term loan (12 months minimum) or a business line of credit (6 months minimum) instead.

If your monthly revenue is under $10,000: Working capital is not sized for micro-operations. A business term loan (minimum $25K) or SBA microloan may fit better, though qualification timelines stretch to 30–90 days.

If your debt-to-income is high (over 12%): You may still qualify, but at a higher cost or smaller loan amount. Work with the lender to restructure existing debt or confirm that upcoming project cash flow will improve your ratio within 60–90 days.

If you're a subcontractor: Subcontractors often qualify for invoice factoring (1–5% per invoice cost) faster than working capital, especially if your GC or client is creditworthy. Factoring also avoids fixed repayment schedules that strain slow-pay months. Check our affordability calculator to compare payment scenarios.

When Working Capital Makes Sense vs. Other Financing

Use working capital when: You need $10K–$100K for a specific, immediate gap (emergency payroll, material shortage, invoice delay spike). Speed matters more than cost. Closing in 24–48 hours beats waiting 30–90 days for SBA approval.

Use a business line of credit when: You have recurring, ongoing cash flow timing gaps. As of July 2026, through our funding partner, business lines of credit run Prime + 3% to mid-20s APR (much cheaper than working capital) with 1–3% draw fees. You draw only what you need, pay only on drawn balance, and redraw as you repay. Best for seasonal contractors who predictably need cash for 6–8 months per year, then repay during busy season.

Use invoice factoring when: Your clients (GCs, property managers, or government agencies) are slow-pay but creditworthy. Factoring converts unpaid invoices into immediate cash—usually 80–90% advance within 24 hours. You pay 1–5% of invoice value (e.g., 1.5% for first 30 days, plus 0.5% per 15 days after). No fixed repayment schedule; you repay as invoices are collected. Ideal for subs and contractors whose cash flow is tied to invoice collection, not project completion.

Use SBA 7(a) loans when: You need larger amounts ($50K–$5M+) on a longer term (10–25 years), and you can afford a 30–90 day approval timeline. SBA loans cost Prime + 2.75–4.75% APR—much cheaper than working capital or factoring—but require 640 FICO, 24 months in business, and $100K+ annual revenue.

Use equipment financing when: You're buying vehicles, machinery, or tools. As of July 2026, through our funding partner, equipment financing runs 8–25% APR over 3–7 year terms, often with 0% down at 650+ credit, and closes in 3–7 days. Better for capital purchases than payroll or material gaps.

Background & How Working Capital Gaps Happen

Construction companies operate on project cash flow. A GC bids a $500K job, wins it, and must immediately order $150K in materials and pay crews for labor—all on 30-day net terms (meaning payment from the client in 30 days, materials due in 14 days, payroll due weekly). The GC has funded $150K out of pocket before the first invoice to the client is even issued. If the client doesn't pay for 45 days, the GC is short $150K for 45 days—during which other payroll, overhead, and material purchases must continue.

Working capital loans close this gap. Instead of waiting for invoices to be collected or taking on expensive short-term credit card debt, you borrow a lump sum at a known cost and repay it over a predictable schedule.

The tradeoff is cost: working capital factor rates (1.15–1.40, or 25–60%+ APR) are expensive compared to SBA loans or lines of credit. But they fund in 24 hours instead of 30–90 days, and they approve at credit scores and time-in-business thresholds that traditional lenders won't touch.

Bottom Line

Working capital is the difference between your cash on hand and what you owe—the buffer that keeps payroll flowing while you wait for clients to pay. Construction companies typically need 30–60 days of operating expenses in liquid reserves to avoid cash crunches. If you can't cover that gap internally, a working capital loan (24-hour funding, 550+ credit) or line of credit (cheaper, but slower setup) are the fastest fixes.
