Invoice Factoring for Contractors

What is invoice factoring for contractors?

Invoice factoring for contractors is a form of receivables financing where a factor (a specialized lender) advances a portion of amounts owed to you by general contractors or owners. You submit an invoice or pay application; the factor assesses the client’s credit and advances typically 70–90% of the invoice value within days. The factor then collects from the client when payment is due. You receive the remainder (minus fees) when the client pays. This converts 30–90 day payment terms into immediate cash. For the broader category, see accounts receivable financing. For contractor invoice financing, see our guide.

How contractor invoice factoring works

Step 1: You complete work and submit an invoice or pay application to the GC or owner. Step 2: You submit the invoice to a factor. Step 3: The factor assesses the client’s (GC or owner) credit. Step 4: The factor advances a portion (often 70–90%) to you within days. Step 5: The client pays the factor when the invoice is due (or you may collect and remit, depending on structure). Step 6: The factor remits the remainder to you, minus fees. The factor’s fee compensates for the advance and credit risk. For more on construction invoice payment delays, see our guide. Ongoing factoring—once your clients are approved, you can factor new invoices as they are generated, maintaining consistent cash flow.

When does invoice factoring make sense for contractors?

Invoice factoring fits when you have clear invoices from creditworthy GCs or owners. Payment terms are long (net-60, net-90) and you need cash sooner. The cost is acceptable for your margin—factoring fees vary; compare against the cost of waiting or other options. You are a sub invoicing a GC, or a GC invoicing an owner. The factor assesses who owes you. You have recurring receivables—factoring can be used repeatedly as new invoices are generated. For one-time gaps, contractor working capital may fit. For recurring gaps, a contractor line of credit may fit. For contractor waiting on invoices, see our guide.

Invoice factoring vs working capital vs line of credit

Invoice factoring is receivable-specific—you factor particular invoices. Working capital is general purpose—you use it for payroll, materials, or other needs. A line of credit is revolving—you draw when needed. The right option depends on your situation. For a full comparison, see all funding options.

What factors look at: your client’s credit matters

Factors focus on who owes you—the GC or owner. Their creditworthiness determines advance rates and fees. Your relationship with the client matters—factors may verify that work was completed and the invoice is valid. Invoice clarity—clear amounts, due dates, and payment terms—helps. Your track record of completed work and paid invoices may be considered. Volume—consistent receivables may improve terms. For contractor slow paying clients, see our guide if client payment is unreliable.

Costs and fees for contractor invoice factoring

Discount fee—a percentage of the invoice value, often 1–5% per 30 days, depending on client credit and payment speed. Factor fee—may be charged as a flat fee or percentage. Advance rate—70–90% is common; stronger client credit may support higher advances. Minimum volume—some factors require minimum monthly volume. Compare total cost against the benefit of having cash now vs waiting. For contractor invoice factoring vs receivables, see our guide.

Client notification—some factoring structures require the client to pay the factor directly; others allow you to collect and remit. Setup fees—one-time fees may apply. Contract length—some factors require minimum commitment periods. Read the agreement and ask about all fees before signing. For contractor waiting on invoices, see our guide on managing payment delays.

Pay application vs invoice—construction factoring often works with pay applications (progress billing) as well as final invoices. The factor assesses the client (GC or owner) and the contract. For subcontractor financing, see our guide on subs’ financing needs. For contractor invoice factoring vs receivables, see our comparison of factoring and other receivables products.

Recourse vs non-recourse factoring

Recourse factoring means you are responsible if the client does not pay. The factor can require you to buy back the invoice or cover the shortfall. Non-recourse factoring means the factor assumes the credit risk if the client does not pay (typically for approved clients). Non-recourse may have higher fees. Understand which structure you are entering. For accounts receivable financing, see our broader guide.

Spot factoring vs full-service factoring: which fits contractors?

Spot factoring (single-invoice factoring) lets you factor one invoice at a time. You choose which invoices to factor. Fits contractors with occasional needs or who want to test the product. Full-service factoring (or whole-ledger factoring) means you factor all or most of your receivables. The factor may provide ongoing advances as new invoices are generated. Fits contractors with consistent receivables and recurring cash flow needs. Minimum volume may apply for full-service. Compare fees and flexibility.

Real-world scenarios for contractor invoice factoring

Subcontractor with net-90 GC. An electrical sub completes $100,000 of work. The GC pays net-90. The sub factors the invoice, receives 80% ($80,000) within 5 days, and uses the cash for payroll and materials on the next project. GC with net-60 owner. A general contractor completes a $500,000 milestone. The owner pays net-60. The GC factors the invoice, receives 85% ($425,000) within a week, and funds mobilization on the next job. Contractor with recurring receivables. A contractor has multiple projects with staggered payment. They factor invoices as they are generated, maintaining consistent cash flow. Each scenario reflects the same pattern: converting receivables to cash before payment terms.

Documentation and process: what factors need from contractors

Invoices or pay applications—clear documentation of work completed and amount owed. Contract or purchase order—shows the underlying agreement. Lien waivers—may be required depending on the project. Client verification—the factor will verify the client (GC or owner) and may contact them. Recourse vs non-recourse—understand who bears credit risk. The process is typically faster than traditional loans because the factor is focused on the receivable and the client’s credit, not your full financial history. For accounts receivable financing, see our broader guide.

How to choose the right product

Consider whether you have clear invoices from creditworthy clients. Consider the cost—compare factoring fees to other options. Consider whether you need recurring access—factoring can be used repeatedly; a line of credit may also fit. Consider recourse vs non-recourse—understand who bears credit risk. Consider spot vs full-service—single-invoice or whole-ledger. Government receivables—see government contractor financing—are often attractive to factors. Start with accounts receivable financing for the broader category and contractor invoice financing for product comparison. If you need to explore options, you can see what funding options may be available for your contracting business.
