Construction Invoice Factoring in California — AR Financing for Subs & Specialty Trades

California construction subs and specialty trades run on a payment cycle that would kill most businesses: material and labor go out weekly, progress bills go in monthly, and GCs pay 45 to 90 days after that — sometimes longer on public jobs with retention held for another year.

Construction factoring exists to bridge that gap. Here's how it works for California subs in 2025 and what to watch out for.

What Construction Factoring Is

You bill your GC or owner on your schedule of values. The factor advances 70–90% of the progress bill (or 80–90% of a T&M invoice) within a few business days. When the GC pays, you get the reserve minus a factoring fee.

Advance rates are lower than in trucking or staffing because construction invoices carry more dispute risk (pay-when-paid clauses, mechanics' lien issues, joint checks, retainage).

What's Different About Construction Factoring

• Pay-when-paid contract language — the factor has to underwrite the GC and the ultimate paying owner.
• Retention is typically not factored (it's held too long and is too dispute-prone).
• Mechanics' lien rights — the factor needs your preliminary notice and lien discipline to be current.
• Joint checks may be required on some jobs, especially public work.
• Bonded jobs can complicate factoring — the bonding company often has first claim on receivables.

What It Costs

Construction factoring fees typically run 2–5% for the first 30 days depending on advance rate and job type. Public work with clean progress billings prices sharper than complex private work with disputes and change-order risk.

Who It Fits Best

Framing, drywall, electrical, plumbing, HVAC, concrete, painting, mechanical, and specialty trade subs. Also service-only contractors (janitorial, facilities maintenance) invoicing REITs and property managers on Net-30 to Net-60.

Fits less well: brand-new subs with no completed jobs, subs working almost exclusively on residential remodels for consumers, and subs with heavy change-order disputes.

Alternatives Worth Considering

Business line of credit. For established subs (2+ years, solid credit) an LOC is usually cheaper than factoring for smoothing normal payment lag.

Working capital term loan. Lump sum against monthly revenue. Better for a specific known need than for ongoing cash flow.

Equipment financing. Fund your excavators, lifts, and vehicles as separate deals — don't tie up your factoring line on capex.

SBA 7(a). For established subs with clean books, SBA is the cheapest capital available. Slow to fund but worth the wait for larger needs.

Common Mistakes

Factoring retention (don't). Signing a factoring agreement without checking whether your bonding company allows it. Not filing preliminary notices — a factor won't advance against invoices with no lien rights. Choosing a generalist factor over a construction-specialized one.

Next Step

Bring your last aging report, a sample progress bill, your top 3 GC/customer names, and your current bonding status. Construction factoring lines typically take 7–14 days to set up; ongoing advances fund in 2–4 days.
