What to know before you choose

San Antonio's construction market runs on subcontracts and progress billings, which means cash flow timing problems are structural, not a sign your business is failing. The right financing product depends on what is causing the gap and how long you can wait for funding.

Working capital loans and credit lines are the first stop for most contractors. Unsecured lines from online lenders typically require $150,000–$250,000 in annual revenue and at least 12 months in business. Rates for creditworthy borrowers (700+) run roughly 8.5–11% APR in 2026; fair-credit borrowers (FICO 620–679) should expect rates 2–4 percentage points higher. Monthly debt service should stay under 45–50% of gross monthly revenue — lenders will calculate this whether you do or not, so run the math before applying.

Invoice factoring solves the slow-pay problem without adding a term loan to your balance sheet. Factoring companies advance 80–90% of the invoice face value within 24–72 hours, then collect from your GC or owner directly. Fees run 1–5% per 30-day period — cheap if the invoice turns in 30 days, expensive if it drags to 90. Many San Antonio specialty trades and HVAC subs use factoring to cover payroll on active jobs without tapping a credit line. For independent contractors and 1099 workers in the metro, alternative financing options in San Antonio follow a similar structure but with lighter documentation requirements.

Equipment financing is purpose-built for trucks, lifts, excavators, and tool packages. Approvals come back in 1–3 days, down payments run 10–20%, and the equipment itself secures the loan — meaning credit requirements are softer than unsecured lines. Under Section 179, you can deduct up to $1,220,000 of qualifying equipment placed in service in 2026, which changes the net cost calculation meaningfully for larger purchases.

SBA 7(a) loans offer the lowest rates (8.5–11% APR) and longest terms (up to 10 years) but require 640+ credit, 24 months in business, and 30–45 days to close. They're the right tool for refinancing high-cost debt or funding a major expansion — not for covering next Friday's payroll. The SBA guarantees up to 85% of the loan, which is why participating banks will lend to contractors who might not qualify for conventional commercial credit.

Merchant cash advances are fast (24–72 hours) and require almost no documentation, but carry APR equivalents of 80–150%. Use them only when a specific, near-term receivable will repay the advance quickly.

What trips people up in San Antonio

• Seasonality underwriting: Lenders reviewing 12 months of bank statements will see the summer slowdown. Have a one-page explanation ready — lenders who work with contractors understand the cycle; generic small-business underwriters often don't.
• Lien waivers and retainage: If 10–15% of every contract is held in retainage, your receivables look smaller than your actual backlog. Factoring companies that specialize in construction will underwrite against the gross contract amount, not just what's been billed.
• License and insurance verification: Texas requires contractor licensing through local municipalities rather than a state-wide license for most trades, but lenders will still verify active general liability and workers' comp before funding. Have current certificates of insurance ready.
• Credit report errors: One in five credit reports contains an error. Pull yours before applying — a disputed tradeline can knock your score below a lender's threshold and delay funding by weeks.

Contractors in neighboring Texas metros face similar dynamics; the same product logic applies to markets like Arlington, TX. If you're comparing options across the region, the underwriting standards in Atlanta, GA illustrate how market size affects lender competition and rate spreads.
