What Is Invoice Factoring? A Guide to Receivables Financing

Invoice factoring converts unpaid invoices into immediate working capital by selling existing receivables at a discount.

What Is Invoice Factoring? The Short Answer

Invoice factoring is the sale of existing accounts receivable at a discount. A business that has already delivered goods or services sells its unpaid invoices to a factor. The factor advances a percentage of the face value today, collects directly from the customer when the invoice matures, and remits the remaining reserve minus a fee.

It is a purchase, not a loan. And it is the other half of the receivables story. A merchant cash advance buys future receipts. Invoice factoring buys invoices that already exist.

Why Invoice Factoring Exists

The interesting part of factoring is who gets underwritten. A bank looks at the seller. A factor looks at the party that pays the invoice, called the account debtor. If the seller is a small staffing company with a weak balance sheet but its invoices are owed by a national hospital system, the factor is underwriting the hospital system.

That shift in focus is why factoring exists. Strong customers and weak sellers produce strong receivables, and strong receivables are the collateral.

How a Factor Underwrites the Receivables File

Factors read the aging report the way an MCA provider reads a bank statement. Three items matter most.

Dilution. Credits, returns, disputes, and write offs shrink the face value of the pool. A pool with high historical dilution gets a lower advance rate or a rejection.

Concentration. If one account debtor makes up more than 20 to 25 percent of the pool, the factor is effectively underwriting a single credit. Limits are set per debtor.

Age. Invoices past 60 or 90 days rarely qualify. The longer an invoice sits unpaid, the lower the probability it pays in full.

Verification and notice of assignment complete the file. The factor confirms the invoice is real and undisputed, then notifies the account debtor to pay into a control account. From that point, collection runs through the factor, not the seller.

Recourse Versus Non Recourse in Invoice Factoring

Recourse and non recourse define who carries the risk of non payment.

Under recourse factoring, if the account debtor fails to pay within the agreed window, typically 60 to 90 days, the seller must buy the invoice back. The factor carries dilution and fraud risk. The seller keeps the credit risk.

Under non recourse factoring, the factor assumes the insolvency risk of the account debtor. Note the precision. Non recourse usually covers insolvency only. A customer that disputes the invoice or simply pays slow still leaves the seller on the hook. That distinction is where most misunderstandings of the product live.

Where Factoring Sits Inside Specialty Finance

Invoice factoring sits between the merchant cash advance and equipment finance. It is existing receivables rather than future receipts, and self liquidating collateral rather than hard assets. Duration is short, tied to the payment terms of the invoice, and the collateral converts to cash on a known date.

Together with Part 1 and Part 2, factoring shows the rest of the receivables business. It covers future receipts, existing invoices, and the underwriting rules that price each one.

The Bottom Line

So what is invoice factoring? It is the purchase of existing receivables, underwritten on the strength of the party that pays, not the party that sells. The details that matter are the ones inside the aging report: dilution, concentration, age, and the recourse line.
