What is subcontractor invoice factoring and how does it work?

Yes — invoice factoring turns unpaid invoices into same-day or next-day cash.

When you factor a subcontractor invoice, you sell it to a third-party lender (called a factor) who advances you 80–95% of the invoice amount immediately—usually within 24–48 hours. The factor then collects directly from your client. You pay a fee of 1.5–3% of the invoice face value per month, plus any other service charges.

The specifics

Subcontractor invoice factoring works like this:

1. You submit an invoice — You've completed work for a GC or property owner and issued an invoice. Instead of waiting 30–90 days for payment, you upload the invoice to your factor.

2. Lender verifies the invoice — The factor checks that the invoice is legitimate, that your client (debtor) is creditworthy, and that the work or materials were actually delivered. This takes a few hours to one business day.

3. You receive 80–95% upfront — Once approved, the factor deposits 80–95% of the invoice value into your bank account. Funding happens within 24–48 hours for most reputable lenders.

4. Factor collects from your client — The factor takes over collection. Your client pays the factor directly, not you.

5. You receive the remainder minus fees — When the factor collects, they deduct their fee (1.5–3% per month) and remit the balance to you. If the invoice is $10,000 and the factor's fee is 2% per month, you keep $9,800 after 30 days.

According to industry data on invoice factoring in construction, the construction factoring market has grown steadily, with subcontractors representing a major user base because slow-paying generals and property owners create chronic cash flow gaps. Construction invoice factoring companies now specialize in subcontractor workflows, allowing for selective factoring (factor just the invoices you need) and rapid underwriting.

Who qualifies? Most factors care far more about your client's credit and the invoice legitimacy than your personal credit score. This makes factoring accessible to subcontractors and equipment operators even with fair or poor credit. You typically need to be in business for at least 6–12 months and have valid, collectable invoices. Factors may also review your recent bank statements (2–6 months) to confirm steady revenue.

Qualification & edge cases

Invoice factoring is not a traditional loan, so qualification rules differ sharply from construction working capital loans or bank credit lines.

When factoring works best:

• Your invoices are to creditworthy clients (major builders, municipalities, established property owners).
• You need cash within days, not weeks.
• Your personal credit is fair or poor but your invoices are solid.
• You work on a per-project or seasonal basis and don't want a standing credit line.

When it's less attractive:

• Your invoices are to unprofitable or high-risk clients (the factor may decline them).
• You prefer a lower all-in cost (factoring fees add up fast over 12 months).
• You want to keep your client relationship confidential (factors often contact your clients directly).

Edge case: Recourse vs. non-recourse. In recourse factoring, if your client defaults, you're liable—the factor demands repayment. Non-recourse factoring shifts default risk to the factor but costs 0.5–1% more per month. Most subcontractors use recourse factoring because their clients are stable.

Alternative: If you prefer a lower-cost standing facility, explore contractor lines of credit requirements or best construction lenders 2026. These require stronger credit and longer approval but cost less than factoring over time.

Background & how it works

Invoice factoring emerged decades ago in retail and manufacturing to solve a universal problem: the gap between when you deliver goods and when you get paid. In construction, that gap is often 45–90 days—sometimes longer on government contracts. Subcontractors, especially small shops and owner-operators, can't absorb that gap without running out of cash for payroll, materials, or equipment maintenance.

Factoring is not a loan. You're not borrowing; you're selling an asset (the invoice) at a discount. That distinction matters legally and financially. Factoring doesn't appear on your personal credit report and doesn't add debt to your balance sheet in the traditional accounting sense.

According to recent data on construction cash flow solutions, factoring has become especially popular in 2026 because traditional bank lines of credit remain hard to access for small subcontractors and because invoice factoring can be set up in days rather than weeks.

The factor's fee structure is typically:

• 1.5–3% per month of invoice face value (the most common model).
• 1% to 3% per month for shorter terms (10–30 days) or longer terms (60+ days).
• Some factors charge an origination or administrative fee ($50–$300 per invoice) on top of the percentage.

Over a year, if you factor invoices consistently at 2% per month, you're paying roughly 24% annually—much higher than a traditional working capital loan, but far faster and easier to access.

Bottom line

Subcontractor invoice factoring converts slow-paying invoices into immediate working capital, with funding in 24–48 hours and minimal credit requirements. It's ideal for subcontractors facing 45–90 day payment cycles from generals or property owners. Fees run 1.5–3% per month, making it pricier than a bank line of credit but faster to deploy when cash is urgent.
