Invoice Factoring for Contractors: Turn Unpaid Bills into Cash Flow

The Contractor Cash Flow Problem

If you are a contractor, you know the drill: you complete the work, submit the invoice, and wait. And wait. Net-30 becomes net-45. Net-45 becomes net-60. Meanwhile, you still have payroll to meet, materials to buy, and equipment payments to make.

This cash flow gap is one of the biggest reasons contractors struggle to grow — or even stay afloat. Invoice factoring solves this problem by converting your unpaid invoices into immediate cash.

What Is Invoice Factoring?

Invoice factoring is not a loan. It is the sale of your accounts receivable to a factoring company (called a factor). Here is how it works:

1. You complete a job and invoice your customer for $50,000
2. You sell that invoice to a factor for $45,000 to $48,500 (90% to 97% of face value)
3. The factor collects payment directly from your customer when the invoice is due
4. Once paid, the factor sends you the remaining balance minus their fee

You get most of your money within 24 to 48 hours instead of waiting 30 to 90 days.

Why Factoring Works Especially Well for Contractors

• No new debt: Factoring is a sale, not a loan. It does not appear on your balance sheet as debt.
• No credit check on you: The factor evaluates your customer's credit, not yours. Bad credit? No problem.
• Scales with your business: The more you invoice, the more you can factor. No arbitrary limits.
• Predictable cash flow: Know exactly when you will get paid — every time.
• Take on bigger jobs: With reliable cash flow, you can bid on larger projects without worrying about funding the work.

Types of Factoring for Construction

1. Spot Factoring

Factor individual invoices as needed. Most flexible but slightly higher fees per invoice.

2. Contract Factoring

Factor all invoices from a specific customer or project. Lower fees due to volume.

3. Construction Factoring

Specialized factoring for construction with progress billing, retainage handling, and AIA document support.

4. Purchase Order Financing

If you need funds to complete a job before you can invoice, PO financing covers material and labor costs.

What Does Factoring Cost?

Factoring fees typically range from 1% to 5% of the invoice value per month. For example:

• $50,000 invoice factored at 2% monthly fee
• If paid in 30 days: $1,000 fee, you receive $49,000
• If paid in 60 days: $2,000 fee, you receive $48,000

While this is more expensive than a bank line of credit, it is often cheaper than missing payroll, turning down work, or taking out high-interest emergency loans.

What Contractors Need to Qualify

• Invoices to creditworthy customers (government, large corporations, established businesses)
• Completed work (factors typically do not fund pre-completion)
• Clean lien waivers and proper documentation
• No major disputes on the invoices being factored
• Personal guarantee (in most cases)

Common Concerns Addressed

Will My Customers Know I Am Factoring?

In most cases, yes — the factor collects directly from your customer. However, many factors operate under your business name, and customers often do not care as long as they can pay the same way.

Does Factoring Hurt My Customer Relationships?

Generally no. Large companies and government agencies are used to working with factors. In fact, some prefer it because factors handle collections professionally.

Can I Factor Retainage?

Most factors will not fund retainage (the 5% to 10% held until project completion). However, some construction-specific factors offer retainage financing as a separate product.
