Best Working Capital Options for Contractors (2026)

Construction is a capital-intensive business with a backward payment structure. You buy materials, pay workers, and cover overhead today. You get paid weeks or months later. That gap — between when money goes out and when money comes in — is why working capital financing exists for contractors.

The good news: there are more options than most contractors realize. The challenge is understanding which product solves which problem, and what each one actually costs. Here’s a straightforward comparison.

What Makes a Working Capital Option Good for Contractors

Not every business financing product works well for construction. Contractors face unique challenges that eliminate some products and make others a natural fit.

Good working capital products for contractors share several traits. They fund quickly, because job-site cash problems don’t wait for a 30-day bank review. They accommodate irregular revenue, because construction cash flow is lumpy — big draws, then nothing, then another draw. They can be tied to a specific project, invoice, or material order rather than requiring steady monthly revenue. And they don’t require collateral that most contractors don’t have, like real estate or major equipment.

The five main working capital products that meet these criteria are: working capital loans and advances, revolving lines of credit, invoice and accounts receivable factoring, material purchase financing, and equipment financing (which is technically separate from working capital but often used in combination).

Working Capital Loans and Advances

Working capital loans — often structured as short-term loans or merchant cash advances (MCAs) — are lump-sum funding products repaid over a fixed term, usually through daily or weekly automatic debits from your bank account.

How they work: You apply with recent bank statements (typically 3–6 months), basic business documents, and sometimes a contractor license and tax returns. The lender reviews your cash flow, deposits, and sometimes your personal credit. Approval takes 24–48 hours. Funding hits your account in 1–3 business days.

Typical terms: Repayment periods range from 3 months to 18 months. Most contractor advances fall in the 6–12 month range. Costs are expressed as a factor rate rather than an interest rate — common factor rates range from 1.15 to 1.45. That means a $100,000 advance at a 1.25 factor rate costs $125,000 total, or $25,000 in fees. Repayment is typically daily or weekly.

Best for: Mobilization costs on a new project, covering payroll during a draw gap, buying materials when a supplier doesn’t offer net terms, or any situation where you need a specific amount of cash quickly with no strings on how it’s used.

Qualification: Most lenders require at least 6 months in business, $10,000–$15,000/month in bank deposits, and a 550+ personal credit score. Some have lower thresholds for contractors with strong cash flow history.

Drawback: The cost is high relative to traditional bank loans. A 1.25 factor rate on a 6-month advance translates to an effective APR well above 50%. This is the price of speed and accessibility — it’s worth it when the cost of not having cash is higher (missed project start, lost crew, delayed material delivery).

Lines of Credit

A revolving line of credit gives you access to a credit pool that you draw from and repay repeatedly. Unlike a term loan, you only pay interest on what you’ve drawn. When you repay, that capacity is available again.

How they work: You apply once, get approved for a maximum amount, and can draw up to that limit at any time. Most construction-focused online lenders offer lines with draw limits of $50,000 to $500,000. Traditional banks may go higher for established contractors with strong financial statements.

Typical terms: Interest rates range from prime + 2% to prime + 8% for qualified borrowers through online lenders, which translates roughly to 9–18% APR in the current rate environment. Some lines charge a draw fee (often 1–3% per draw) in addition to interest. Lines are typically renewed annually.

Best for: Contractors who have recurring, predictable cash gaps — like covering payroll and overhead between every draw cycle, or managing the slow season every year. A line of credit is a tool you set up before you need it and keep available as a buffer.

Qualification: Most online lenders require 12+ months in business, $120,000+ in annual revenue, and a 600+ personal credit score. Bank lines typically require 2+ years in business, strong financials, and often a personal guarantee or collateral.

Drawback: Lines of credit take longer to set up (1–2 weeks typically) and have stricter qualification requirements than working capital advances. They’re also not a good fit for one-time large capital needs — they’re a revolving tool, not a project funding tool.

See contractor line of credit for more detail on qualification and draw mechanics.

Invoice and Accounts Receivable Factoring

Invoice factoring converts outstanding invoices — approved pay applications sitting at a GC’s office — into immediate cash. The factoring company advances you 80–90% of the invoice value now. You get the remaining 10–20%, minus fees, when the GC pays.

How they work: You submit the invoice and basic documentation about the project and the GC. The factor verifies that the invoice is valid and the GC is creditworthy. If approved, the advance hits your account within 24–48 hours. When the GC pays the invoice (30, 60, or 90 days later), the factor remits your reserve amount minus the factoring fee.

Typical terms: Factoring fees range from 1.5% to 5% per 30-day period. On a $200,000 invoice factored at 3% for 60 days, the total fee is approximately $12,000 — you’d receive roughly $188,000 rather than waiting 60 days for the full $200,000. Many factoring companies have a minimum invoice size of $10,000–$25,000.

Best for: Subcontractors or GCs with large approved pay applications outstanding. Factoring is ideal when you have confirmed, approved receivables and can’t afford to wait for the GC’s payment cycle.

Qualification: Factoring is underwritten primarily on the creditworthiness of the party owing the invoice (the GC or owner), not the contractor’s credit. This makes it accessible to contractors with limited credit history.

Drawback: You can’t factor an invoice that doesn’t exist yet. If work isn’t billed or the pay application is disputed, there’s nothing to factor. Also, factoring notifies the GC that you’ve assigned the invoice to a third party — some contractors prefer to keep this private.

Material Purchase Financing

Material purchase financing pays your supplier directly for job-specific materials. You repay over a short term (typically 60–120 days) once you’ve received your draw. Think of it as a bridge between ordering materials and getting paid for installing them.

How they work: You provide a purchase order or material list, the project contract, and basic business information. The lender pays the supplier directly or advances funds earmarked for materials. Repayment is structured around the expected draw date.

Typical terms: Fees range from 2–6% for the term, which is often 60–90 days. On a $50,000 material order, a 3% fee for 90 days costs $1,500 — a relatively low cost to ensure materials are on-site when work starts.

Best for: Subcontractors with specific, large material orders who need to pay suppliers before receiving a draw. Particularly useful for electrical, plumbing, HVAC, and framing contractors where material costs make up a large portion of job cost.

Drawback: It’s project-specific. You typically need a contract and purchase order in hand, which means it’s not useful for general cash flow management.

See contractor material purchase financing for more information.

Equipment Financing

Equipment financing is technically separate from working capital — it’s a long-term product used to acquire machinery and vehicles, not to fund operations. However, understanding the distinction matters for cash flow.

When contractors finance equipment rather than paying cash, they preserve working capital for operations. A $120,000 excavator financed over 60 months at 8% APR costs about $2,430/month — which is far easier to absorb from project revenue than paying $120,000 out of operating cash.

Equipment financing typically requires the equipment itself as collateral, which means lower rates (5–15% APR for qualified buyers) and no impact on your working capital reserves. It’s worth separating clearly from your operational cash planning.

See construction equipment financing for details on equipment-specific financing.

How to Choose Based on Your Situation

If you need cash in 48 hours: Working capital advance or invoice factoring. Both can fund in 1–3 days if you have the documentation ready.

If you have a large approved pay application sitting at a GC: Invoice factoring converts that invoice into immediate cash without adding new debt.

If cash gaps happen every month: A revolving line of credit is cheaper and more flexible over time. Set it up before you need it.

If you need materials for a specific job: Material purchase financing keeps that cost off your operating credit and ties repayment to the draw.

If you’re buying equipment: Finance it separately. Don’t use working capital for capital purchases — it ties up revolving capacity for operational costs.

If you have time (30+ days) and strong financials: Explore SBA options for the lowest rates, or work on qualifying for a bank line of credit.

The most common mistake contractors make with working capital is waiting until a crisis to look for it. The best time to secure a line of credit or explore factoring is when you don’t need it urgently — your options are better, your rates are lower, and you’re not making decisions under pressure.

Frequently asked questions

What is the fastest working capital option for contractors?

Working capital advances (sometimes called merchant cash advances or short-term business loans) are typically the fastest, with approvals in 24–48 hours and funding in 1–2 business days. Invoice factoring can also be fast — sometimes same-day once the factor has verified the invoice and the GC's creditworthiness.

What credit score do contractors need for a line of credit?

Most online lenders require a minimum personal credit score of 600–620 for a revolving line of credit. Traditional banks typically want 680 or higher. Some factoring and working capital products have no minimum credit score requirement, instead focusing on cash flow and invoice quality.

Can a contractor get working capital with bad credit?

Yes. Working capital advances and invoice factoring are the most accessible products for contractors with low credit scores. These products are underwritten primarily on cash flow (bank statements) and invoice quality rather than personal credit history. Expect higher rates as a tradeoff.

How much working capital can a contractor qualify for?

Working capital advances typically range from $10,000 to $2 million, with most small to mid-size contractors qualifying for $25,000–$500,000. Lines of credit for contractors commonly range from $50,000 to $500,000. Invoice factoring can scale with your outstanding receivables, potentially into the millions for larger subcontractors.

Is it better to use a line of credit or a working capital loan?

A line of credit is better for contractors who have recurring, predictable cash gaps — it stays open so you can draw and repay repeatedly. A working capital loan or advance is better for a one-time, specific need, like funding mobilization on a new project or covering payroll during a slow stretch. Lines of credit are generally cheaper per dollar borrowed if you're disciplined about repayment.
