Construction Business Loans: The Real Options for GCs and Subs in 2026

Construction business loans are financing products that cover payroll, materials, and overhead while a contractor waits to get paid on a job — not just one product, but a menu that spans bank term loans, SBA loans, equipment financing, short-term working capital, and revenue-based funding. The right one depends on what you're actually solving: a growth purchase, or a cash-flow gap.

That distinction matters because construction has a cash-flow gap that's structurally different from almost any other industry.

The construction cash-flow problem, in plain numbers

A GC or sub finishes real work, submits a pay application, and then waits. And waits. According to Billd's 2025 construction payments data, subcontractors wait an average of 56 days after submitting a pay app to get paid — and Siteline's 2025 industry report puts the average subcontractor payment cycle at 96 days, up from 90 days in 2019. Depending on the job, the GC, and the state's retainage rules, the real range most contractors experience runs somewhere between 51 and 96 days.

Now stack that against the other number that matters: margin. According to CFMA's Construction Financial Benchmarker, the typical construction firm runs a net profit margin around 6% — with a healthy range of roughly 5–8% for well-managed companies. That's thin. A contractor operating on a 6% margin can't afford to float 60-90 days of payroll, materials, and equipment costs out of pocket without something breaking.

Payroll runs weekly. Material suppliers want net-30. Equipment leases don't pause because a GC is slow-walking an approval. Meanwhile the receivable sitting in someone else's AP department is real money — it's just not liquid yet. That gap is the entire reason "construction business loans" is a search category, and it's exactly the kind of timing problem — not a credit problem — that revenue-based funding is built to solve (the cash-flow benchmarks by industry show how sharp it is in construction).

Why the gap is worse for GCs and subs than most industries

Retail and service businesses get paid at the point of sale, or close to it. Construction doesn't work that way. A sub submits a pay app to a GC, the GC reviews and bundles it with everyone else's, the owner's rep reviews the GC's draw request, the lender or fund controller signs off, and only then does money move — often with a retainage holdback of 5-10% carved out until the job (or a phase of it) closes out entirely. Every link in that chain adds days, and none of them are the sub's fault or within the sub's control.

That's the structural piece that separates a "construction cash-flow problem" from a generic "my business needs money" problem. The work is done. The value has been delivered. The invoice is legitimate. What's missing is liquidity, not revenue — and that's a fundamentally different problem than the one a struggling business has. It's also exactly the kind of gap a bank underwriting model is bad at recognizing, because a bank looks at trailing financials and collateral, not the fact that $180,000 of completed, billable work is sitting in someone else's approval queue right now.

Multiply that by the number of active jobs a mid-size GC or sub is running at once — three, five, a dozen — and the gaps stack. One job's pay app clearing doesn't fix the cash crunch if two other jobs just fell into their own 60-day windows. This is why so many contractors describe their business as "always tight" even in a strong revenue year: it's not that the money isn't coming, it's that it's perpetually a job or two behind where the bills already are.

Why banks turn down contractors with real revenue

Here's the part that trips up a lot of GCs and subs: a bank declines you and it feels personal, or like your business isn't good enough. Usually it isn't that. Banks underwrite the owner's personal credit, collateral, and — often — job-cost transparency the bank's underwriter isn't equipped to evaluate. A contractor with $80,000/month in draws but a 580 credit score, or a contractor who's simply too new to have two years of clean tax returns, gets a form-letter decline regardless of how strong the actual book of business is.

The data backs this up. According to the Federal Reserve's 2024 Small Business Credit Survey, roughly 44% of applicants got full approval at large banks — and separately, Biz2Credit's Small Business Lending Index has tracked big-bank approval rates hovering in the 13-15% range on a monthly application basis. However you slice it, a meaningful share of contractors with legitimate, revenue-generating businesses walk into a bank and walk out with nothing — not because the business is broken, but because the underwriting model doesn't see cash flow the way a contractor's bank statements do.

That's the hinge: a bank term loan underwrites the owner. Revenue-based funding underwrites the business's actual deposits and revenue trend. If your problem is a timing gap on real receivables — not a broken business — a revenue-based structure is built for exactly that mismatch.

There's also a credit-history problem specific to contracting. A lot of solid operators came up through the trades, not through business school, and their personal credit reflects a rougher patch years back — a slow season, a medical bill, a divorce — that has nothing to do with how they run a crew today. Bank underwriting doesn't forgive that easily. A model that looks at what your business is actually depositing month over month gives a more honest read on whether you can service financing than a FICO score frozen in a moment from years ago.

The real financing options for contractors

Not every option below fits every problem. Here's an honest breakdown.

Bank term loan / SBA loan. The cheapest money if you can get it. Best for a contractor with strong personal credit, two-plus years of clean financials, and a purchase or expansion that isn't time-sensitive — new equipment, a facility, a buyout. Slow (weeks to months), collateral-heavy, and the approval bar described above knocks out a lot of otherwise-solid contractors. Byzfunder's own Byzwash-fulfilled Term Loan is a faster-underwritten version of this same instrument for qualifying borrowers.

Equipment financing. Purpose-built for buying or leasing a specific piece of equipment — an excavator, a crane, a fleet truck — where the equipment itself is the collateral. If your gap is specifically "I need to buy a machine," this is usually the right tool, and it's worth shopping equipment-financing specialists directly. Note: Byzfunder does not offer equipment financing — this is a different product category, and if that's your specific need, a dedicated equipment lender or lease company is the better fit.

Short-term working capital. A defined, fixed-term advance meant to bridge a specific, bounded gap — cover payroll for six weeks until a big draw clears, front materials for a job that's already been awarded. Faster underwriting than a bank, shorter term than a traditional loan. See our breakdown of short-term business loans for how these are structured.

Revenue-based financing (MCA). Not a loan — a purchase of a portion of your future receivables, repaid via a fixed factor rate (not an APR) as revenue comes in, typically through small, automated remittances tied to your deposits. This is the option best matched to the construction pay-app gap specifically: underwriting looks at your bank deposits and revenue trend, not just your FICO score, so a contractor with a timing problem — not a credit problem — has a real shot. Read more on how revenue-based financing actually works.

Revolving capital. For contractors who don't have one gap — they have a recurring one, job after job. Byzfunder's ByzFlex is revenue-based revolving capital (not a line of credit): draw against it, repay as revenue comes in, draw again on the next job without reapplying from scratch each time.

Matching the option to the actual problem

The mistake most contractors make isn't picking a "bad" financing option — it's picking the wrong one for the specific gap they're trying to close. A few quick ways to sort it:

• If the need is a specific piece of equipment — a skid steer, a new work truck, a crane rental buyout — that's an equipment-financing conversation, not a working-capital one. The equipment secures the debt, which usually means a better rate than an unsecured product.
• If the need is "I have six weeks between now and a big draw clearing" — that's a short-term working capital bridge, sized to the specific gap and paid off when the draw lands.
• If the need is recurring — every job has this same lag, job after job — a one-time advance just delays the problem to the next job. That's when revolving capital, something you can draw against repeatedly without reapplying from scratch, actually fixes the pattern instead of patching one instance of it.
• If the credit file is rough but the revenue is real — bank and SBA products are probably closed to you right now regardless of how the business is actually performing. Revenue-based funding is underwritten around what the business deposits, not the owner's credit history alone.

None of these are mutually exclusive over the life of a business — a contractor might use equipment financing for a truck purchase this quarter and revenue-based funding to bridge a slow-paying GC next quarter. The point is matching the tool to the specific gap, not defaulting to whatever's fastest to apply for.

How to qualify and get approved fast

Whichever route you go, the underwriting moves faster when you show up prepared. For revenue-based funding specifically, here's what tightens the timeline:

• Have 3-6 months of business bank statements ready. This is the core underwriting document for revenue-based funding — it shows deposit consistency, not just a snapshot.
• Know your monthly revenue number cold. Underwriters are checking whether your deposits are trending up, flat, or down — be ready to explain any dip (slow season, GC payment delay, etc.).
• Separate business and personal banking if you haven't already. Mixed accounts slow down every underwriting process, bank or otherwise.
• Have your entity documents and a voided check or bank letter handy. Basic paperwork, but missing it is the single most common reason a fundable file sits for an extra day.
• Be honest about existing advances or loans. Stacking undisclosed positions is the fastest way to get an underwriter to slow down or decline.
• Apply once your job pipeline is visible, not mid-crisis. A contractor who applies with an active backlog of awarded jobs underwrites better than one applying the week payroll is due.

Bottom line

Construction doesn't have a profitability problem in the aggregate — margins average around 6% per CFMA, which is thin but real. What it has is a timing problem: cash goes out on payroll and materials weekly, while cash comes in 51 to 96 days after a pay app is submitted, per Billd and Siteline's 2025 data. A bank term loan is the cheapest way to fund a purchase if you qualify, and equipment financing is the right tool for buying a specific machine. But when the problem is the gap itself — a contractor with real revenue and a slow-paying GC, not a broken business — revenue-based funding that underwrites deposits instead of just credit score is usually the faster, more realistic fit. Byzfunder funds directly, evaluates the business you actually have, and construction is the vertical we fund more than any other.

FAQ

What credit score do I need for a construction business loan?

It depends on the product. Traditional bank and SBA loans typically want strong personal credit (often 680+) plus two years of financials. Revenue-based funding evaluates deposits and revenue trend alongside credit, which opens the door for contractors with less-than-perfect scores — see business loans for bad credit for how that underwriting works.

Can I get funded if I'm waiting on a pay application from a GC?

Yes — that's the exact gap revenue-based funding and short-term working capital are built for. Underwriting looks at your existing revenue and deposit history, not whether a specific invoice has cleared yet.

Is an MCA the same as a loan?

No. A merchant cash advance is a purchase of a portion of your future receivables, repaid via a fixed factor rate as revenue comes in — it is not a loan and does not carry an APR. That structure is why underwriting can move faster than a traditional term loan.

What's the difference between ByzFlex and a business line of credit?

ByzFlex is revenue-based revolving capital, not a line of credit. You draw against it and repay based on revenue, without the credit-line underwriting structure a bank line uses.

Does Byzfunder offer equipment financing?

No. Equipment financing is a distinct product category built around the equipment itself as collateral, and Byzfunder does not offer it. If buying or leasing a specific machine is your primary need, a dedicated equipment lender is the better fit — Byzfunder's products are built for working-capital and cash-flow gaps instead.

How fast can a contractor actually get funded?

Byzfunder funds same-day to within 24 hours for qualifying files once documentation is complete. Bank and SBA timelines run weeks to months by comparison.

Why did I get declined by my bank if my business is doing fine?

Bank underwriting weighs the owner's personal credit and collateral heavily, and often doesn't have a clean way to evaluate job-cost cash flow or receivables in progress. A contractor with real, growing revenue can still get declined on that basis — it's a mismatch between the underwriting model and how construction cash flow actually works, not necessarily a reflection of the business.

What documents do I need to apply?

Typically 3-6 months of business bank statements, basic entity documents, and a voided check or bank letter. No lengthy business plan or years of tax returns required for revenue-based funding, unlike a bank or SBA application.
