How Invoice Factoring Fees Actually Work

Factoring pricing can feel opaque if you're new to it. The good news is that almost every factoring arrangement boils down to three moving parts: the advance rate, the reserve, and the fee. Here's how they fit together.

The advance rate

The advance rate is the percentage of the invoice value you receive upfront. If you factor a $10,000 invoice at an 80% advance rate, you get $8,000 right away.

Advance rates commonly range from around 70% to 90%, depending on the customer's credit, your industry, and the invoice size.

The reserve

The reserve is the portion the factor holds back until the invoice is paid in full. Using the same example, the remaining $2,000 is held in reserve. Once your customer pays, the factor releases the reserve to you — minus the fee.

The reserve isn't a fee; it's a hold that comes back to you. It exists to protect the factor against short-pays and deductions.

The fee

The fee is what the factor charges. There are three common ways it's calculated:

• Flat fee: A fixed percentage of the invoice, regardless of how long it takes to collect. Simple and predictable.
• Tiered (volume-based) fee: The rate steps down as your factoring volume goes up, rewarding businesses that factor more.
• Time-based (discount rate) fee: The fee increases the longer the invoice is outstanding — for example, a rate for the first 30 days, then an additional rate for each period beyond. This aligns cost with how long the factor's money is out.

Putting it together

For a $10,000 invoice at an 80% advance, a 2% flat fee, and a 30-day collection:

• You receive $8,000 upfront.
• Your customer pays the factor $10,000.
• The factor keeps $200 (the 2% fee) and returns the $1,800 reserve to you.
• Your total received: $9,800.

What to watch

The single most important thing is understanding which fee structure you're being offered and how it behaves if your customer pays late. A low flat fee can be a better deal than a low time-based rate that climbs quickly. Always ask: what's the advance rate, what's the fee, and what happens if the invoice isn't paid on time?
