What is invoice factoring?

Invoice factoring converts approved invoices to early cash through assignment. The agreement—not the label—controls fees, recourse, and collection rights.

Invoice factoring is a receivables financing method where a business sells or assigns unpaid invoices to a third party called a factor in exchange for immediate cash. Rather than waiting 30, 60, or 90 days for customers to pay, the business receives an advance—typically 75 to 95 percent of the invoice face value—within one to three business days of submitting the invoice.

The transaction starts when the business completes delivery of goods or services and issues an invoice to the commercial customer. That invoice is submitted to the factor along with supporting documents: a signed bill of lading for trucking, approved timecards for staffing, or proof of delivery for other service industries. The factor reviews both the invoice and the creditworthiness of the customer who owes payment.

If the invoice passes review, the factor funds the advance. The business gets early access to working capital it would otherwise wait weeks for. The factor then collects directly from the customer, usually after sending a notice of assignment that tells the customer to pay the factor rather than the original seller.

After the customer pays in full, the factor releases the remaining balance—the reserve—minus its fees. If the advance was 85 percent on a $10,000 invoice, the business received $8,500 upfront. The remaining $1,500, less the factoring fee, comes back as reserve settlement. The timing of that reserve release is governed by the agreement, not just by the fact of customer payment.

Factoring fees go by several names: discount rate, discount fee, purchase discount, or simply the factor's fee. The structure matters as much as the number. A 2 percent flat fee means the cost is fixed regardless of how long the customer takes to pay. A tiered fee steps up the longer the invoice is outstanding. A daily rate multiplies by each day until the customer pays. Understanding which structure applies determines actual cost.

Approval in factoring focuses primarily on the creditworthiness of the customer—the account debtor—rather than the business submitting the invoice. A startup or a company with a difficult financial history can access factoring if its customers are solid commercial accounts with consistent payment patterns. That distinction makes factoring accessible in situations where a bank line of credit may not be an option.

Not every invoice qualifies for funding. Factors set credit limits for each customer and may decline invoices that exceed those limits, involve a disputed amount, carry anti-assignment language in the underlying contract, are too old, or come from a customer with a weak payment history. Program approval does not guarantee every invoice will be funded.

The factor's interest in receivables is typically documented through a UCC-1 financing statement filed in the state where the business is organized. This filing gives public notice of the security interest and establishes priority relative to other creditors. The filing remains active until the factor files a termination after the relationship ends.

Factoring is generally written as a purchase or assignment of receivables rather than a loan—a distinction with accounting and regulatory implications. But recourse provisions, personal guarantees, and repurchase obligations can create financial obligations that function economically like debt, regardless of how the contract labels the transaction.

For businesses considering factoring, the most important preparation is reading the complete agreement rather than relying on summaries from a sales call. The terms that determine actual cost and risk—advance rate, reserve percentage, fee structure, recourse period, chargeback triggers, minimum volumes, UCC collateral scope, and termination costs—vary considerably across programs and are all found in the written contract.
