Construction Company Working Capital & Bridge Financing in San Diego, CA

Scan the options below, match your situation — payroll gap, slow-pay invoice, equipment bridge, or government contract float — and go straight to the guide that fits. If you're not sure which product applies, the orientation below will sort it out in two minutes.

What to know before you choose

San Diego's construction market runs on net-30 to net-90 payment cycles from GCs and government agencies, which means cash flow gaps are structural, not a sign your business is struggling. The financing options that exist in 2026 range from same-week factoring to SBA programs that take 30–45 days to close — and picking the wrong tool costs you either time or money.

Who each option fits

• Invoice factoring — Best for subcontractors sitting on unpaid receivables from creditworthy GCs or public agencies. Factoring companies advance 80–90% of the invoice face value and fund in 1–3 business days, charging 1–5% of the invoice amount. You're not taking on debt; you're accelerating cash already owed. This is the fastest path to payroll coverage without touching your credit line.

• Working capital loans / merchant cash advances — Right for general contractors who need a lump sum to cover materials, mobilization, or overhead and don't have invoices ready to factor. Online lenders price these at 15–45% APR depending on credit and revenue. They move fast, but the cost compounds quickly if you hold the balance long. Use them for 60–120 day bridges, not chronic shortfalls.

• Business line of credit — The most flexible tool for contractors who cycle in and out of cash gaps regularly. Lines run 8–20% APR for qualified borrowers and let you draw and repay on your schedule. Most lenders require $250,000+ annual revenue, a 640+ FICO, and 12 months of bank statements. If you qualify, this is almost always cheaper than repeated short-term loans.

• SBA 7(a) loans — Rates of 8.5–11% APR in 2026, up to $5,000,000, with the SBA guaranteeing up to 85% of the loan. Approval takes 30–45 days and requires 24+ months in business and a 640+ credit score. These are the right call for larger bridges — government contract mobilization, a major project ramp — where the timeline works. They are not an emergency payroll fix.

• Equipment financing as a bridge — If you're replacing or acquiring equipment, a standalone equipment loan (5.5–9% APR for 700+ credit) frees your working capital for operating costs. San Diego heavy equipment firms often pair an equipment note with a smaller line of credit rather than using a single larger working capital loan. Lenders in this space typically close in 1–3 days. For a detailed comparison of heavy equipment loan structures available locally, construction equipment financing options in San Diego is worth reviewing before you apply.

What trips people up

The most common mistake is applying for the cheapest product (SBA) when you need the fastest one (factoring or online working capital). The second most common mistake is using a merchant cash advance for a problem that a line of credit would solve at half the cost — because the line takes a week longer to set up.

Lenders across all these products will pull 12 months of bank statements and want to see a debt service coverage ratio of at least 1.25x. They'll also cap total debt payments at 43–50% of gross monthly revenue. If you're already carrying equipment loans or a draw on a line, model that math before you apply.

Contractors running solar installation crews have an additional option worth knowing about: specialized solar contractor working capital programs in San Diego that account for the milestone-based payment schedules common on those projects.

San Diego contractors evaluating options available in other California metros can also compare how lenders structure deals in Anaheim or look at how regional lenders serving western markets approach the same products in Anchorage — underwriting standards vary more than most borrowers expect.
