What Invoice Factoring Actually Is (And Is Not)
Invoice factoring is a financing arrangement where you sell your unpaid invoices to a third-party company — called a factor — in exchange for an immediate cash advance. The factor typically advances you 80% to 95% of the invoice face value upfront, then collects payment directly from your customer. Once your customer pays, the factor sends you the remaining balance minus their fee.
This is not a loan. You are not borrowing money against your invoices — you are selling them. That distinction matters for your balance sheet, your tax obligations, and your personal liability.
Here is what a typical factoring transaction looks like:
| Step | What Happens | Timeline |
|---|---|---|
| 1. Submit invoice | You send your unpaid invoice to the factor | Day 0 |
| 2. Verification | Factor confirms the invoice is legitimate with your customer | 1-3 days |
| 3. Advance | Factor sends you 80-95% of the invoice value | 1-3 days |
| 4. Collection | Factor collects full payment from your customer | 30-90 days |
| 5. Rebate | Factor sends you the remaining balance minus fees | Upon collection |
Factoring fees typically range from 1% to 5% per 30 days the invoice remains outstanding. On a $10,000 invoice with a 3% monthly factor fee, you would pay $300 if your customer pays within 30 days. If they take 60 days, you may owe $600. That cost adds up fast, so it can be useful to understand exactly how fees are calculated before signing any agreement.
