Invoice Factoring Explained: How to Turn Unpaid Invoices into Immediate Cash

Published: January 2026 | Category: Business | Reading Time: 11 minutes

Waiting 30, 60, or even 90 days for customers to pay invoices can strangle your cash flow, even when business is booming. Invoice factoring offers a solution: turn your unpaid invoices into immediate cash, typically within 24-48 hours.

This guide explains invoice factoring from start to finish: how it works, what it costs, the pros and cons, and how to determine if it makes sense for your situation.

What Is Invoice Factoring?

Invoice factoring is a financial transaction where a business sells its accounts receivable (invoices) to a third party (called a factor) at a discount. The factor advances you most of the invoice value immediately, then collects payment from your customer.

How Factoring Works

You sell $10,000 invoice → Factor advances $8,500 (85%) → Customer pays factor → Factor sends you remaining $1,200 (keeping $300 as fee)

Understanding Factoring Costs

Factoring fees typically range from 1-5% per month, depending on invoice volume, customer creditworthiness, invoice size, industry, and payment terms.

Types of Factoring

Recourse Factoring: If your customer does not pay, you must buy back the invoice. Lower fees but higher risk.

Non-Recourse Factoring: Factor absorbs bad debt risk (with limitations). Higher fees but protection for you.

When Factoring Makes Sense

  • Rapidly growing businesses needing cash to fund growth
  • Seasonal businesses bridging cash flow gaps
  • Startups that cannot qualify for traditional bank financing
  • B2B companies with long payment terms from creditworthy customers

When to Avoid Factoring

  • You can qualify for cheaper financing (lines of credit, SBA loans)
  • Customers already pay quickly (net 15 or faster)
  • Low profit margins that cannot absorb fees
