What to know about construction working capital and bridge financing in Portland

Portland's construction market runs on public infrastructure, commercial retrofit, and residential infill — all of which share the same cash-flow problem: work gets done weeks before money arrives. Whether you're a subcontractor waiting on a GC's 60-day pay cycle or a heavy equipment firm covering fuel and operator wages between mobilizations, the financing product you reach for should match the specific gap you're filling.

The four tools most Portland contractors use — and who each fits:

• Short-term working capital loans — Best for firms with $250,000+ in annual revenue that need $25K–$500K to cover payroll or materials right now. Online lenders run 15–45% APR; approval and funding in 1–3 business days. High cost, but fast.
• Business line of credit — Better than a term loan if your cash gaps are recurring and unpredictable. Rates run 8–20% APR from banks and credit unions. Requires stronger financials and usually 12 months of bank statements, but you only pay interest on what you draw.
• Invoice factoring — Ideal for subcontractors with outstanding invoices from creditworthy GCs or public agencies. You advance 80–90% of invoice face value within days, paying a 1–5% fee. No debt on the balance sheet, no minimum credit score requirement from most factors. Portland solar and trade contractors, for example, use this heavily — the same mechanics that apply to working capital options for Portland trade contractors apply here.
• SBA 7(a) loans — Best for established firms (24+ months in business, 640+ FICO) that can wait 30–45 days for approval. Rates run 8.5–11% APR in 2026, up to $5,000,000, with the SBA guaranteeing up to 85% of the loan. Lowest long-term cost, slowest to close.

What separates the products in concrete terms:

Product	Typical APR	Funding Speed	Min. Revenue	Min. FICO
Online working capital loan	15–45%	1–3 days	$250K+	~600
Business line of credit	8–20%	3–7 days	$150K+	~650
Invoice factoring	1–5% fee	1–3 days	None set	None set
SBA 7(a)	8.5–11%	30–45 days	Varies	640+

What trips people up:

The most common mistake is reaching for a high-cost merchant cash advance when invoice factoring would have done the same job at a fraction of the price. If you have billable receivables — even if your credit is thin — factor first.

The second mistake is applying for an SBA loan when the payroll deadline is in ten days. SBA processing alone runs 30–45 days. Use a bridge product to cover the immediate gap, then refinance with an SBA loan once the project is under contract.

Debt load is also a real disqualifier. Most lenders want total monthly debt service below 43–50% of gross monthly revenue. If you're already carrying equipment notes and a lease, an unsecured working capital loan may not pencil — a secured line against your receivables or equipment may be the only viable path.

Portland contractors with active government contracts have one additional option: federal contract financing, sometimes called mobilization loans. These are structured around the contract value rather than your balance sheet, which opens the door for firms that would otherwise fall short on revenue or collateral thresholds. Contractors across the Pacific Northwest use these — as do firms in markets like Anchorage and Atlanta where public-sector work dominates the pipeline.

The guides linked below go deeper on qualification criteria, lender comparisons, and step-by-step application walkthroughs for each product. If you're also evaluating equipment financing alongside working capital — common when a new project requires a machine purchase — Portland-area solar and specialty contractors comparing equipment financing vs. working capital face the same tradeoffs, and the rate and term structure is nearly identical across trades.
