Construction Invoice Factoring: Get Paid on Your Invoices This Week, Not in 90 Days

The Subcontractor Cash-Flow Trap

The math of subcontracting works against your cash flow. You mobilize a crew, buy materials, and perform the work this week, but the general contractor pays your invoice in 30, 60, or often 90 days, and retainage can sit even longer. The bigger the job you win, the bigger the gap you have to float. Growth, paradoxically, makes the squeeze worse: every new project ties up more cash before it returns a dollar.

Construction invoice factoring exists to close that exact gap. Instead of waiting out the GC's payment terms, you convert the approved invoice into cash the same week, money you've already earned, released when you need it rather than when the payment chain finally clears.

The principle behind this page is simple: your growth shouldn't be capped by 30–90 day payment terms. If the work is done and the invoice is real, the cash it represents should be working for you now.

How Construction Factoring Works, Step by Step

Factoring is straightforward once you see the four moves.

1. You invoice the GC as usual. Complete the work, or the current stage of a progress-billed job, and issue your invoice to the general contractor exactly as you do today.

2. You submit the approved invoice to the factor. The factor verifies the work and the amount with the GC. This verification, and the standard notice of assignment (which tells the GC to remit payment to the factor), is normal and expected in construction, GCs deal with factored subs routinely.

3. The factor advances ~80–95% of the invoice. Cash typically lands within 24–48 hours of verification. The advance rate depends on the trade, the GC's credit, and the program, stronger commercial customers support higher advances.

4. The reserve releases when the GC pays. When the general contractor pays the invoice on its normal timeline, the factor releases the remaining balance (the reserve) minus its fee. You keep the difference.

Because funding is tied to your receivables, it scales automatically: the more you invoice creditworthy GCs, the more capital you can pull forward, with no fixed ceiling to renegotiate the way a bank line requires.

It's Not a Loan, and Why That Matters for Contractors

This is the distinction most contractors miss, and it's the most important one.

Factoring is the sale of an asset you already own, an earned, unpaid invoice. It is not borrowing. There is no fixed monthly payment, no new liability added to your balance sheet, and nothing to refinance down the road.

For a contractor, that has real consequences beyond convenience. Because factoring doesn't add debt, it preserves your borrowing capacity for the times you actually need a loan, and it keeps the balance sheet that sureties read clean, so a properly used factoring line can support bonding capacity rather than eroding it. You're monetizing receivables, not leveraging the company.

Recourse vs. non-recourse. Programs differ in who carries the risk if an approved GC ultimately fails to pay. Recourse factoring holds the subcontractor responsible for a non-paying invoice; non-recourse factoring means the factor absorbs approved-customer credit risk. The trade-off is cost versus protection. PeerSense confirms which structure applies before you engage, so there are no surprises if a project chain goes sideways.

What the Cash Actually Funds

Factored invoices free up cash for the things that let a sub take on more work and bigger jobs.

Payroll. Cover crews already on the job without waiting for the GC, the single most common use, because labor can't wait 60 days.

Materials. Buy lumber, steel, concrete, fixtures, and specialty materials that have to be purchased and delivered before the next progress payment arrives. Some construction-factoring programs pair the receivables advance with dedicated materials financing so a large material buy doesn't drain the advance.

Bigger jobs and bonding capacity. The liquidity from a steady factoring line strengthens the working-capital position sureties look at, which is often the real ceiling on how large a contract you can bid. More reliable cash flow means you can pursue contracts that were previously out of reach.

Multi-stage / progress-billed jobs. On long jobs billed in stages, factoring each approved progress billing keeps cash flowing across the full project rather than lumping at the end, and progress-billing management is built into many construction-specific programs.

Who Qualifies, Read This Before You Apply (B2B Only)

Factoring qualifies on the credit of your CUSTOMER, not your own balance sheet, which is exactly why a fast-growing sub can access capital a bank line would decline. But it only works for a specific profile. Match yourself against these before spending time on an application.

B2B commercial invoices only, this is the hard line. The invoice must be owed by another business: a general contractor, a developer, a commercial property owner, or a government/institutional client. Invoices billed directly to homeowners, individual consumers, or residential retail customers (B2C) are NOT factorable. The entire model depends on underwriting a creditworthy commercial debtor and verifying a commercial payment obligation, a consumer receivable can't be underwritten that way. If your work is primarily direct-to-homeowner residential, factoring is the wrong tool; a working-capital line or another structure fits, and PeerSense will point you there instead of sending you to a factor that will decline.

Creditworthy commercial customers. The factor is underwriting the GC or owner who ultimately pays, so the strength of your customers matters more than your own financial statements. A strong GC on the other side of the invoice can outweigh a thin sub balance sheet.

Completed, verifiable work. Invoices must represent work actually performed and confirmable with the GC. Progress billings on multi-stage jobs qualify as each stage is billed and approved.

Construction trade / subcontractor operation with real receivables. The sweet spot is a growing sub whose backlog outruns its cash, trades like electrical, mechanical, framing, concrete, drywall, HVAC, plumbing, site work, and specialty.

Standard mechanics to expect. Notice of assignment to the GC and invoice verification are routine; advance rates commonly run 80–95%; and many programs carry no minimums, so smaller subs can start and scale as they grow. Because the underwriting follows the project chain, owner to GC to sub, a well-capitalized project can make an otherwise-marginal sub bankable.

What PeerSense Does

PeerSense is a capital advisory and matchmaking firm, not a lender or a factor. We help construction subcontractors find the right factoring partner and structure, and we pre-screen the fit before anyone's time is wasted: is the receivable B2B and commercial, is the GC creditworthy, is the work verifiable, and is factoring even the right tool versus a working-capital line. When it fits, we match you to a factor whose program suits your trade, your volume, and your customers; when it doesn't, we say so and point you to the structure that does.

That routing is grounded in data: PeerSense has analyzed lending and financing patterns across 5,475 lenders and 2.1M loans, with 899 credit boxes profiled, so your receivables go to a source that actively funds construction subs, rather than being shopped blind to a factor that will pass.

PeerSense earns a fee at closing only. Economics are aligned with getting you funded on the right terms.

If you're a subcontractor whose backlog is outrunning your cash flow, share your trade, monthly invoicing volume, and who your commercial customers are in the form above. You'll get a structure recommendation and indicative advance terms within 24 to 48 hours.
