Subcontractor Financing

What is subcontractor financing?

Subcontractor financing refers to funding options that help electrical, plumbing, HVAC, concrete, roofing, and other specialty subcontractors manage cash flow while waiting for payment from general contractors. Unlike general contractors who may invoice owners or developers directly, subcontractors typically submit pay applications or invoices to the GC. The GC then pays according to their schedule—often net-30, net-60, or net-90 from the date of the pay application. That delay creates a cash flow gap: subs pay labor weekly, buy materials on delivery, and cover overhead while waiting for the GC to pay. Subcontractor financing bridges that gap. For the broader picture, see contractor cash flow problems.

Why subcontractors face unique cash flow pressure

Subcontractors operate in a payment chain. The owner pays the GC; the GC pays the sub. Each step adds time. A sub may complete work in week one, submit a pay application in week two, and wait 60–90 days for payment. Meanwhile, the sub’s crew expects pay every Friday. Material suppliers want payment on delivery. Insurance, bonding, and overhead continue. The sub has performed the work and has a valid claim to payment—but the cash has not arrived. This structure is built into construction; it is not a sign of poor management. Understanding it helps subs plan. For more on construction invoice payment delays, see our dedicated guide.

Common funding options for subcontractors

Contractor working capital provides short-term funds for payroll, materials, or mobilization when a pay application is pending. It is often a one-time advance. Subs use it when they know payment is coming but need cash now. Accounts receivable financing—also called invoice factoring—converts amounts owed by the GC into immediate cash. A lender advances a portion (often 70–90%) of the invoice value; the sub repays when the GC pays. This fits when the GC is creditworthy and payment terms are predictable. Contractor line of credit offers revolving access for recurring gaps. Subs who work on multiple projects with staggered payment schedules may draw as needed. Construction equipment financing fits tool, vehicle, and equipment purchases. For material-specific needs, see contractor material purchase financing.

When does each option make sense?

Working capital fits a single gap—one payroll period or one material order while a pay application is pending. It can be faster than applying for a line of credit. Invoice factoring fits when you have clear invoices or pay applications from creditworthy GCs and need to convert them to cash quickly. The factor assesses the GC’s credit; your relationship with the GC matters. Line of credit fits when you have recurring gaps—multiple projects, staggered draws, or seasonal patterns. You draw when needed and repay when payments arrive. Equipment financing fits when the need is machinery or vehicles, not operating cash flow. Matching the product to your pattern improves the fit. For payroll-specific gaps, see contractor payroll funding.

How payment terms from general contractors affect subs

GC payment terms vary. Some pay within 30 days of approval. Others stretch to 60 or 90 days. Retainage—typically 5–10% held until project completion—extends the wait for final payment. Subs should understand the GC’s payment cycle before bidding. If the GC pays net-90 and you have a 15-person crew, you need funding to cover 12+ weeks of payroll before the first payment. Contractor working capital or a contractor line of credit can bridge that period. For retainage-specific pressure, see contractor retainage cash flow.

What lenders look at for subcontractor financing

Lenders typically review revenue history—consistent work and payment from GCs. Bank activity and average deposits indicate cash flow. Time in business matters; many products require at least six months. The GC’s credit matters for invoice factoring; the factor is effectively lending against the GC’s obligation to pay. Bonding and licensing may be required for some projects; lenders consider whether you can perform. Project mix—residential vs commercial, public vs private—affects risk. Subs with a track record of completed work and paid applications typically have more options. For preparation guidance, see how to prepare for contractor financing approval.

Subcontractor vs general contractor financing: key differences

General contractors often invoice owners or developers directly. Subcontractors invoice the GC. That difference affects invoice factoring—the factor evaluates the party that owes you (the GC). It also affects payment timing—you wait for the GC, who may be waiting for the owner. Bonding is more common for subs on public and large commercial work; contractor bonding and financing explains how they interact. Project structure—fixed price, time and materials, cost-plus—affects when you can bill. Subs on T&M may bill more frequently; subs on lump sum may wait for milestones. Understanding your place in the chain helps you choose the right product.

Pay application vs invoice: when can you factor?

Subcontractors typically submit pay applications (progress billing) rather than final invoices. Factors may advance against approved pay applications—once the GC has approved the amount, the obligation is clear. Unapproved applications may not qualify; the factor needs to know the GC has committed to pay. Retainage—the portion held until completion—may not be factored until the project is complete. Understanding the difference between “work completed” and “approved for payment” helps you time factoring. For more on contractor draw schedule cash flow, see our guide.

Documentation that helps subs qualify for financing

Pay applications and GC approval show that work is done and payment is committed. Contract copies or purchase orders clarify scope and payment terms. Bank statements with consistent deposits from GCs show payment history. Lien waivers (if required) may be part of the process—ensure you understand the implications. Bonding and licensing documentation may be required for some projects. Subs who keep clear records and can demonstrate timely payment from GCs typically have more options. For contractor bonding and financing, see our guide.

Real-world scenarios for subcontractor financing

Electrical sub on commercial build-out. An electrical contractor completes $80,000 of work and submits a pay application. The GC pays net-60. The sub has 12 electricians to pay weekly. Working capital covers payroll until the payment arrives. Plumbing sub on multi-family project. A plumbing sub has invoices from a national GC with strong credit. Invoice factoring advances 80% within days; the sub uses the cash for materials on the next phase. HVAC sub with overlapping projects. An HVAC contractor has three jobs in progress with draws staggered over 8 weeks. A line of credit provides flexibility—draw when payroll hits, repay when draws land. Concrete sub with material timing. A concrete contractor needs $50,000 in cement and aggregate for a foundation pour. The supplier wants payment on delivery; the GC pays net-90. Material purchase financing bridges the gap. Each scenario reflects the same pattern: work is done, payment is coming, but cash is needed now.

How to choose the right product for your sub business

Consider how often you need funds—one-time vs recurring. Consider who owes you—GC credit matters for factoring. Consider your project mix—steady work supports a line of credit; sporadic work may fit working capital. Consider documentation—some products require less than traditional bank loans.

Frequently asked questions

What is subcontractor financing?

Subcontractor financing is funding that helps electrical, plumbing, HVAC, and specialty subs cover payroll and materials while waiting for payment from general contractors. GCs often pay net-60 or net-90; subs need cash during that wait.

Why do subcontractors need financing?

Subs complete work and submit pay applications or invoices to the GC. Payment may not arrive for 30–90 days. Labor must be paid weekly; materials are often paid on delivery. The timing gap creates cash flow pressure.

What funding options do subcontractors use?

Working capital for short-term gaps, invoice factoring or accounts receivable financing to convert GC invoices to cash, and lines of credit for recurring needs. Equipment financing fits tool and vehicle purchases.

How does subcontractor financing differ from general contractor financing?

Subs typically invoice the GC rather than the end client. Payment flows through the GC. Invoice factoring for subs often focuses on GC receivables. The products are similar; the structure of who owes you differs.

Can subcontractors finance invoices from general contractors?

Yes. Accounts receivable financing and invoice factoring can advance a portion of amounts owed by GCs. The factor or lender assesses the GC's credit. Terms vary by product and GC payment history.
