What to know before you choose a financing option

Seattle contractors face the same cash-flow timing problem that hits construction businesses everywhere: you're paying crew and suppliers weeks or months before a GC or public agency cuts your check. The Puget Sound market adds its own wrinkles — prevailing-wage requirements on public projects, a dense subcontractor ecosystem where payment disputes back up the chain, and material costs that track with the region's sustained commercial and infrastructure build-out. The financing product that solves your problem depends almost entirely on how quickly you need cash, how strong your receivables look, and what your credit and time-in-business profile allows.

Invoice factoring is the fastest path to liquidity if you have outstanding invoices from creditworthy GCs or public agencies. Factoring companies advance 80–90% of invoice face value and fund in 1–3 business days. Fees run 1–5% of the invoice amount — not cheap on an annualized basis, but no collateral beyond the receivable is required and your credit score matters less than your customer's. This is the right tool when a slow-paying owner or GC has you in a bind and payroll won't wait.

Working capital loans and lines of credit fit contractors who need a revolving cushion rather than a one-time advance. Online lenders move fast (often 1–5 business days to fund) but price accordingly — expect 15–45% APR. A bank or credit union line of credit runs 8–20% APR but requires stronger financials, typically 12 months of bank statements, $250,000+ in annual revenue, and a DSCR of at least 1.25x. Lenders also watch that total monthly debt service stays below 43–50% of gross monthly revenue, so bringing in a second line while carrying an equipment loan can push you over the threshold.

SBA 7(a) loans offer the most favorable terms — 8.5–11% APR in 2026, up to $5,000,000, with the SBA guaranteeing up to 85% of the balance — but the process takes 30–45 days and requires 640+ credit and at least 24 months in business. They work well for established contractors who want to refinance expensive short-term debt, fund a large equipment purchase alongside working capital, or lock in a long-term line before a big infrastructure contract starts. Seattle solar installation contractors navigating similar cash-flow cycles will recognize the same tradeoff: equipment financing for Seattle solar contractors sits at the same crossroads between speed and cost.

Equipment financing is distinct from working capital — the equipment itself is the collateral, approval typically takes 1–3 days, and rates for contractors with 700+ credit run 5.5–9% APR. If your cash crunch is tied to needing a new excavator or crane rather than covering overhead, equipment financing is almost always cheaper than a working capital loan. Seattle contractors comparing these two options in detail should also look at construction equipment financing options for Seattle contractors, which breaks down SBA, lease, and direct-lender structures side by side.

Bridge loans fill a specific gap: you've won a contract, mobilization costs are due, but the first draw is 60–90 days out. Bridge terms are short (3–18 months), rates are higher, and lenders want to see the contract or award letter as their exit. They're not interchangeable with a revolving line.

Quick comparison by situation

Situation	Best-fit product	Typical speed	Rate range
Slow-paying GC, invoices outstanding	Invoice factoring	1–3 days	1–5% per invoice
Payroll gap, no single large invoice	Online working capital loan	1–5 days	15–45% APR
Established firm, want low-cost line	Bank LOC or SBA 7(a)	2–6 weeks	8–20% APR
Equipment needed, not overhead	Equipment financing	1–3 days	5.5–9% APR
Contract won, mobilization due	Bridge loan	1–2 weeks	Varies, typically 12–24% APR

Contractors in other high-cost metro markets — including those exploring subcontractor financing in Anchorage or working capital structures used by firms in Atlanta's commercial construction sector — run into the same product-fit questions, and the same credit and revenue thresholds apply nationwide. The Seattle-specific factor is mainly lender familiarity with Washington state lien laws and public-works payment timelines, which some regional lenders price into their risk assessments.

What trips most contractors up: applying for the wrong product (a term loan when they need a revolving line), underestimating how much documentation banks require, or burning time on an SBA application when the cash need is immediate. Start with the guide that matches your timeline, not the one with the lowest advertised rate.
