What Is Invoice Factoring? A Small Business Guide

What Is Invoice Factoring?

Invoice factoring is when a business sells its unpaid invoices to a third party, called a factoring company or "factor," in exchange for immediate cash.

You do not take on debt. You are not borrowing against future revenue. You are selling an asset you already own: a receivable that a customer owes you.

Here is what that looks like in plain terms: you invoice a client for $50,000 with net-60 payment terms. A factoring company advances you $42,500 (85%) within 24 to 48 hours. Your client pays the factoring company $50,000 at the end of the 60 days. The factor sends you the remaining $7,500 minus its fee (say, $1,500). You end up with $41,000 net on a $50,000 invoice, and you got most of it in two days instead of two months.

How Invoice Factoring Works: Step by Step

The mechanics are straightforward once you see the flow.

Step 1: You deliver and invoice. You complete work or deliver a product and send an invoice to your customer with net-30, net-60, or net-90 payment terms.

Step 2: You submit the invoice to the factor. You send the invoice to your factoring company. They verify that the work was completed and that the customer is creditworthy.

Step 3: You receive the advance. The factor wires you 70% to 90% of the invoice face value, usually within 24 to 48 hours. This is called the advance rate.

Step 4: The factor collects from your customer. Your customer is notified that their payment should go to the factoring company. The factor handles collections on that invoice.

Step 5: You receive the reserve. Once your customer pays, the factor releases the remaining balance to you, minus the factoring fee. This remainder is called the reserve release.

The notice of assignment

Most invoice factoring arrangements require you to notify your customer that their payment is being assigned to a factoring company. This is called a notice of assignment. Your customer's payment goes directly to the factor.

Some business owners are comfortable with this. Others prefer to keep the arrangement private. Both preferences are valid, but they lead to different products. If keeping it confidential matters, see Section 5 on invoice financing.

Invoice Factoring Rates and Hidden Costs

Factoring fees are typically expressed as a percentage of the invoice face value. The two most common structures are flat rate and tiered rate.

Flat rate factoring: The factor charges a single percentage regardless of when the invoice is paid. Example: 3% of the invoice value. On a $50,000 invoice, that is a $1,500 fee no matter how quickly your customer pays.

Tiered rate factoring: The factor charges a base rate for the first 30 days and an additional rate for each 30-day period the invoice remains unpaid. Example: 2% for the first 30 days, 0.5% for each additional 30 days. On a $50,000 invoice paid at 45 days, the cost is 2.5% = $1,250. The same invoice paid at 90 days costs 3.5% = $1,750. The longer your customers take to pay, the more you spend under a tiered structure.

Factoring fees for small businesses generally fall between 1% and 5% of the invoice value per 30-day period. Where you land depends on invoice volume (higher volume means lower rates), your customers' creditworthiness, average invoice size, industry, and recourse vs. non-recourse structure.

Hidden fees to watch for

Get the full fee disclosure before signing. Common additional charges include application or due diligence fees (one-time setup), monthly minimum fees if your volume drops below a threshold, wire fees per transfer, audit fees for annual review, early termination fees if you exit a contract before the term ends, and a larger reserve holdback than the stated rate implies.

Recourse vs. Non-Recourse Factoring Explained

This is one of the most misunderstood distinctions in factoring.

Recourse factoring: If your customer does not pay (or goes bankrupt), you are responsible for buying back the invoice from the factor. The factor's risk is limited to your customer paying late. It does not absorb the loss if the customer fails to pay at all. Most small business factoring is recourse, and rates are lower because the factor is taking on less risk.

Non-recourse factoring: The factor absorbs the loss if your customer fails to pay due to insolvency or bankruptcy. You are not on the hook for the unpaid invoice. Non-recourse has higher fees (typically 0.5% to 1% more per period) and comes with stricter qualification requirements on your customers.

Recourse factoring is the right default for most businesses. If your customers are large, creditworthy companies with solid payment track records, the additional cost of non-recourse protection is hard to justify. If you work with smaller customers in volatile industries, non-recourse might be worth the premium.

Invoice Factoring vs. Invoice Financing: What Is the Difference?

These two terms are often used interchangeably. They are different products.

Invoice financing, also called accounts receivable financing or AR financing, is a revolving line of credit secured by your outstanding invoices. You pledge invoices as collateral, draw funds, collect from customers yourself, and repay as invoices are paid. Your customers are typically not notified.

If keeping the arrangement confidential matters to your business relationships, invoice financing is usually the better path. If you want the fastest, simplest cash access without managing collections, factoring is the cleaner choice.

Who Qualifies for Invoice Factoring?

Factoring qualification works differently than nearly every other financing product. The factor's primary concern is your customers' creditworthiness, not yours.

What factors look for: Are your customers creditworthy companies that will pay? Factors run credit checks on the companies that owe you money, not primarily on you. If you invoice large corporations, government agencies, or well-established businesses, you are a strong factoring candidate regardless of your own credit history. Credit access gaps are most pronounced for newer businesses with limited credit history, which is exactly why factoring is so valuable for B2B startups: it underwrites your customers, not you.

Factors also verify that invoices are for completed work. They want to see receivables for goods delivered or services performed. They will not advance on invoices for work not yet completed. The invoices also cannot already be pledged as collateral elsewhere. If you have an SBA loan with a blanket lien on your assets, you need to resolve that before factoring. Many factoring companies also require $10,000 to $50,000 per month in invoice volume to participate.

What does NOT disqualify you: Low personal credit score (580, 550, or lower in some cases), short time in business, unprofitable recent months, previous bankruptcies (depends on the factor), and no tax returns on file. A startup that landed a contract with a government agency can often factor those invoices from day one. That is a capability no traditional loan product can match.

Industries That Use Invoice Factoring Most

Invoice factoring works best for B2B businesses with consistent invoicing and customers who pay on extended terms. According to the U.S. Small Business Administration, access to working capital is one of the top barriers for small business growth. Factoring was built specifically to solve the payment timing problem.

Construction and subcontracting: Project-based work with 30 to 90 day payment cycles creates constant cash flow gaps. General contractors often hold payments until they are paid by the owner, creating long waits for subs.

Staffing agencies: Payroll is weekly. Client payments are net-30 to net-60. That gap is the factoring use case in its purest form.

Trucking and freight: Freight brokers and carriers invoice shippers who pay on standard terms. Fuel, repairs, and driver pay cannot wait 45 days.

Manufacturing: Large orders require raw material purchases upfront. Customers pay 60 to 90 days later. Factoring bridges the production-to-payment gap.

Government contractors: Government agencies are highly creditworthy but notoriously slow payers. Federal contract payments often run 30 to 45 days after invoice, making factoring an efficient tool for contractors.

Healthcare: Medical billing against insurance is a specialized form of factoring called medical receivables factoring. The payer is the insurance company, not the patient.

Wholesale distribution: Distributors buy inventory to fill orders and wait for retailers to pay. Factoring keeps inventory moving without eating through reserves.

If your business does not invoice other businesses on payment terms, factoring is likely not a fit. Consumer-facing businesses with credit card or cash sales generally turn to other products like merchant cash advances or revenue-based financing.

Pros, Cons, and When to Use Invoice Factoring

Factoring is one tool. Whether it is the right tool depends on your situation.

Why businesses use invoice factoring: Speed (approval in 24 to 72 hours, funding on each invoice within 24 to 48 hours once onboarded). No debt (you are selling an asset, not borrowing, which keeps your debt ratios clean). Credit-independent (your credit history is not the primary qualification factor). Outsourced collections (the factor chases payment on your behalf). Scales with revenue (as your invoice volume grows, your factoring capacity grows with it without a new approval process).

What to be aware of: It costs more than a line of credit. A business line of credit at 8% to 15% APR is cheaper than factoring fees that can translate to 24% to 48% annualized. As of May 2026, the Federal Reserve prime rate is 6.75%, which anchors bank product pricing. Customer visibility is also a consideration: most factoring arrangements notify your customers, and some businesses need to manage that conversation carefully. Customer concentration is another factor: if 80% of your invoices come from one customer and that customer defaults, your factoring arrangement is in trouble. And contract terms can lock you in with minimum volume requirements.
