How can I finance infrastructure projects and keep cash flow steady?

Infrastructure Project Financing for Contractors

Yes — infrastructure contractors, heavy equipment firms, and subcontractors can finance payroll, materials, and project gaps with working capital loans ($10K–$500K), bridge financing, or invoice factoring, funded in as little as 24 hours with credit scores as low as 550. Get your rate in 2 minutes with no credit-score impact.

The specifics

Infrastructure financing splits into three main paths, each suited to different project rhythms and cash flow gaps:

Working Capital & Quick-Turn Loans
Fast short-term loans (3–24 months, $10K–$500K) cost a factor rate of 1.15–1.40 (roughly 25–60%+ APR equivalent) but fund in 24–48 hours. Minimum credit score is 550, minimum time in business is 6 months, and minimum monthly revenue is $10K+. These work best for payroll timing gaps, supplier discounts, or emergency repairs between invoice payments. According to the Bankrate 2026 working capital lending survey, speed and cash availability rank above rate for contractors on infrastructure projects.

Bridge Loans
Medium-term bridge financing (12–36 months, $50K–$2M+) closes gaps between project milestones or refinancing. The bridge lending market is accelerating in 2026, with rates ranging 8–15% APR depending on credit and collateral. Minimum credit is typically 600–640, and you'll need 12+ months in business and $100K+ annual revenue. Best for contractors bridging the time between contract award and the first invoice payment on large infrastructure jobs.

Invoice Factoring (for Subcontractors & Government Work)
Sell unpaid invoices at a 1–5% discount per invoice (e.g., advance up to 90% in 24–48 hours). No credit score minimum, no personal guarantee required in most cases, and the factor absorbs payment risk. Minimum time in business is 3 months, and you need $25K–$50K/month in factorable invoices (government, municipal, or private commercial invoices). Ideal for subcontractors waiting 30–90 days on public infrastructure contracts. The SBA highlighted invoice factoring as a working capital solution for homebuilders and infrastructure firms managing multi-month payment cycles.

Qualification & edge cases

Credit scores below 600 are still fundable—working capital loans approve at 550+, though rates climb into the high-factor range (1.35–1.40). If your credit sits 620–679 (fair range), expect a 3–5% APR premium on top of standard equipment or term-loan pricing.

Time in business is flexible. Working capital and factoring require only 6 months minimum; SBA loans and equipment financing want 12–24 months. If you're under 12 months, bridge loans or factoring may be your only path—or a business line of credit ($10K–$250K at Prime + 3% to mid-20s APR, funded 1–3 days) if you have good cash flow.

Revenue thresholds matter. Working capital and factoring need $10K+/month minimum. Larger SBA loans (7a) and business term loans ($25K–$1M+) require $100K+/year. If you're a startup or under-revenue sub, factoring is often your fastest entry: no revenue floor, only invoice volume.

Government contract financing is a special case. Contract value, bonding eligibility, and the contract itself become collateral. The 2026 construction market remains active on public infrastructure work, and several lenders specialize in federal, state, and local contract financing—often at better rates than standard working capital because the contract is secured.

Background: why infrastructure contractors need bridge and working capital financing

Infrastructure projects—roads, bridges, water systems, utilities—operate on long payment cycles. Public agencies often hold Net-30, Net-60, or even Net-90 payment terms. A contractor awarded a $500K municipal road job may not see the first invoice payment for 6–8 weeks, but payroll, equipment rental, and material suppliers demand payment in 7–14 days. That gap is where working capital loans and bridge financing close the mismatch.

Subcontractors and equipment firms face even sharper pressure. A heavy equipment rental company may finance $50K in diesel and maintenance upfront but wait two months to invoice the general contractor, who waits another month for the owner. Invoice factoring eliminates that wait: the factor advances 70–90% of the invoice immediately, and the contractor or owner pays the factor directly.

Construction lenders in 2026 report steady demand for working capital solutions, particularly on infrastructure and public works projects where payment cycles are predictable but long. Rates have stabilized in the 8–15% APR range for bridge loans and term loans, while fast working capital (factor-based) runs 25–60%+ APR equivalent—a trade-off for 24-hour funding and no revenue minimum.

Equipment financing—separate from working capital—is another option if you're purchasing or upgrading fleet. Equipment loans (8–25% APR, 3–7 business days, terms matched to asset life) are secured by the equipment itself, so credit requirements are looser (minimum 580 FICO). Use the affordability calculator to compare monthly payments across equipment loans, working capital, and term loans for your specific project needs.

Bottom line

Infrastructure contractors can access funding within 24 hours using working capital loans, bridge financing, or invoice factoring—even with credit as low as 550. The structure depends on your gap: payroll timing calls for working capital or LOC; long milestone delays call for bridge loans; unpaid invoices call for factoring.
