Invoice factoring for small business

Small businesses with commercial B2B invoicing can qualify for factoring based on their customers' credit rather than their own. This guide covers what determines eligibility, what the setup process involves, and what contract terms to scrutinize before signing.

Most small businesses that factor invoices do so because they're caught between delivering work and waiting 30 to 90 days to collect. The business does the work, invoices the customer, and the factor pays a large portion of it immediately—typically 80 to 93 percent. What makes factoring different from almost every other form of small business financing is that approval is driven by the credit quality of the business's customers, not the business itself.

A new business with less than a year of history can qualify for factoring if it invoices large, creditworthy commercial accounts. A staffing firm six months old that places workers at a regional hospital system, a trucking company that hauls for a national retailer, or a light manufacturer supplying a Fortune 500 customer—all of these can be approved for factoring that would be unavailable to them through a bank. The factor's primary risk is whether the customer will pay the invoice, not whether the small business has three years of audited financials.

Invoice volume determines which programs are available. Most standard factoring programs require $10,000 to $25,000 in monthly invoices at minimum. Some smaller or specialty programs accept less, but they charge higher per-invoice fees to compensate. A business with one $3,000 invoice per month is generally below the threshold where factoring is economical on either side. Know your expected monthly volume before approaching factors to identify programs that are actually sized for your operation.

The type of customers you invoice matters as much as their credit. Factoring applies to commercial receivables—invoices issued to businesses, government agencies, and other legally identifiable entities that have agreed to pay for goods or services already delivered. Consumer receivables, deposits, conditional payments, and invoices with built-in retainage are more difficult to factor and sometimes ineligible entirely. The factor's underwriting team will review the legal character of each customer, not just their payment history.

Setup takes longer than most new clients expect. The application, UCC search, customer credit review, and lien clearance process typically takes five to ten business days for an initial account. During that window, the factor is also verifying that no prior lender has a senior lien on the receivables—an active bank line of credit secured by accounts receivable must either be subordinated or paid off before factoring can begin. Businesses that have an existing bank relationship should budget extra time for this coordination.

The first 90 days involve more verification than later periods. When the factor encounters a new customer for the first time, they may call to verify the invoice before funding. After a few payments have cleared, they build a payment history on that customer and future invoices typically fund faster. Small businesses that invoice the same accounts repeatedly tend to settle into a predictable funding rhythm within the first quarter of the relationship.

Small business owners often focus on the discount rate when comparing programs, but the contract structure matters more in practice. A 12-month term with a $15,000 monthly minimum means a $180,000 invoice commitment over the year regardless of actual business volume. Slow months do not reduce the obligation—they trigger a shortfall fee instead. Request a shorter initial term or a lower minimum if your volume is seasonal or inconsistent. Most factors will negotiate on these terms for new clients who are otherwise a good fit.

Total cost per invoice is a more useful comparison than headline rates. Two programs with different rate structures—one charging 1.5 percent per 10-day period, another charging a flat 3 percent—produce different costs depending on how long your customers actually take to pay. Calculate the net you would receive on a typical $20,000 invoice after advance, fees, and reserve release, using your customer's actual payment timeline rather than the best-case scenario the factor quotes.
