Invoice Factoring for Small Business: How It Works, Costs and Best Providers

Invoice factoring puts cash in your account within 24 hours by selling your unpaid B2B invoices to a third-party company (called a factor) at a discount of 1-5% per invoice. It is not a loan, so it adds no debt to your balance sheet.

Roughly 60% of small businesses struggle with cash flow management, according to PYMNTS research. If your customers take 30, 60, or 90 days to pay, factoring bridges that gap so you can make payroll, buy inventory, or take on new contracts without waiting. The demand for accounts receivable financing is projected to grow at a compound annual growth rate of 9.5-10.5% through 2031.

This guide walks you through how invoice factoring works, what it costs, who qualifies, and which providers offer the best rates in 2026. If you are also exploring other cash flow options, check out our guides on business lines of credit and working capital loans.

Invoice factoring (also called accounts receivable factoring) is a financial transaction where you sell outstanding invoices to a factoring company at a slight discount. The factor pays you an upfront advance (typically 80-95% of the invoice value), then collects payment directly from your customer. Once the customer pays the full amount, the factor sends you the remaining balance minus its fee.

Here is a real-numbers example. You have a $10,000 invoice with net-30 terms. The factor offers a 90% advance rate and a 2% discount fee. You receive $9,000 upfront (90% of $10,000). When your customer pays the full $10,000, the factor keeps $200 (the 2% fee) and sends you the remaining $800. Your total cost is $200 for getting paid 30 days early.

Factoring differs from traditional business loans in several important ways. There is no interest rate or monthly repayment schedule. Your customer's creditworthiness matters more than yours. And the transaction does not create new debt, since you are selling an asset (your receivable) rather than borrowing against it.

Qualifying for invoice factoring is significantly easier than qualifying for a bank loan. Factors care primarily about your customers' credit, not yours. If your customers are creditworthy commercial businesses or government entities with a history of on-time payments, you are likely eligible.

Here are the typical requirements across most factoring companies as of 2026:

• Business type. You must be a B2B or B2G (business-to-government) company that invoices other businesses. Consumer invoices (B2C) are not eligible for factoring.
• Customer creditworthiness. Your customers need solid commercial credit. Government contracts are generally considered low-risk. Large corporations and established businesses with consistent payment histories receive the best treatment from factors.
• Monthly invoice volume. Some factors require minimum monthly volumes. altLINE requires at least $15,000/month in invoices. Gateway Commercial Finance sets a $25,000/month minimum. However, other providers like FundThrough and Riviera Finance have no monthly minimums.
• Your credit score. Most factoring companies do not have a hard personal credit score minimum. Your own credit may be reviewed but carries far less weight than your customers' payment history. Businesses with poor or no credit history can still qualify.
• Legal standing. You need a formalized business structure (LLC, corporation, etc.), a business bank account, and no open bankruptcies. Outstanding tax liens can complicate approval, though some factors work with businesses that have liens in certain situations.

If you are a startup without an established credit history, factoring can be an excellent option. Providers like altLINE work with startup staffing agencies, new distributors, and nonprofit startups, as noted by LendingTree.

The application process is faster than almost any other type of business financing. Most providers let you apply online in under 10 minutes, and initial setup takes 3-7 business days. After that, ongoing invoice submissions typically fund within 24 hours.

Start by pulling your accounts receivable aging report, which lists all outstanding invoices and their ages. You will also need your articles of incorporation, tax ID number, government-issued ID, and recent bank statements. Connect your accounting software (QuickBooks, Xero, or FreshBooks) if the factoring company supports direct integration, since this speeds up invoice verification.

Submit your application to your chosen factoring company and wait for them to verify your customers' commercial credit. The factor will send a Notice of Assignment (NoA) to your customers, informing them that future payments on factored invoices should go to the factoring company. Once verification is complete, select the invoices you want to factor, submit them, and receive your advance, usually within one business day.

The headline cost is the discount fee (also called the factoring rate), which typically ranges from 1% to 5% of the invoice's face value per 30-day period, according to multiple industry sources including Porter Capital and United Capital Source. The industry average hovers around 2.5% per 30 days.

But the discount fee is not your only cost. Watch for these additional charges:

• Origination/setup fees of $150-$500 (or up to 1% of your credit line), as reported by NerdWallet for altLINE.
• ACH and wire transfer fees of $5-$30 per transaction. altLINE's ACH fees start at $0, but other providers charge per transfer.
• Monthly minimum volume fees if you factor less than the required monthly amount.
• Late payment penalties that add 0.5% per additional 10-15 day period if your customer pays past the original invoice terms.
• Early termination fees if you exit a long-term contract before it expires.

Variable-rate structures can increase your cost if customers pay slowly. A factor may charge 2.5% for the first 30 days and then add another 0.5% every 10 days the invoice remains unpaid, as described by eCapital. If your customer takes 60 days to pay, your effective rate on that invoice jumps to 4%.

Non-recourse factoring (where the factor absorbs the risk if your customer does not pay) costs more than recourse factoring. If minimizing your risk is a priority, expect to pay a higher discount fee for non-recourse terms.

Factoring works best for B2B businesses with creditworthy customers and invoices with net-30 to net-90 terms. If that does not describe your situation, here are other options to explore:

• Invoice financing (invoice discounting). Similar to factoring, but you keep control of collections and your customers are never notified. Fees typically run 1.5-2.5%. Good if you want confidentiality. Read more about invoice financing in our full guide.
• Business line of credit. Draw funds as needed and pay interest only on what you use. Requires stronger credit (usually 600+) and 6+ months in business.
• SBA microloans. Borrow up to $50,000 at rates averaging 8-13% for startups and small businesses. See our SBA microloan guide.
• Merchant cash advance. Get a lump sum repaid through a percentage of daily sales. Expensive (effective rates of 20-40%+) but fast. See our merchant cash advance guide.
• Small business grants. Free money with no repayment, though highly competitive. See our small business grants guide.

If your credit is below 600 and you do not have B2B invoices, a merchant cash advance or business credit card may be your most accessible options, though both come at a higher effective cost.

1. Ignoring the total cost of factoring. Advertisers lead with low discount rates like "starting from 1.95%" but do not mention origination fees, wire fees, and volume minimums. Always request a complete fee schedule and model your annual cost before signing.

2. Signing a long-term contract without understanding termination clauses. Some factoring agreements lock you in for 12-24 months with early termination fees. If your cash flow improves and you no longer need factoring, you could be stuck paying for a service you do not use or face a steep exit penalty.

3. Factoring invoices with thin profit margins. If your margin on a project is only 5% and the factoring fee is 3%, you have cut your profit by more than half. Only factor invoices where the cost of early cash meaningfully benefits your operations.

4. Failing to vet your customers' creditworthiness. The factor will do its own credit check, but you should proactively track which customers pay on time and which do not. Factoring invoices from chronically late payers triggers variable-rate penalties and erodes your net recovery.

5. Not comparing at least 3 providers. Rates, advance percentages, contract terms, and ancillary fees vary widely. Taking the first offer without shopping around can cost you thousands over the course of a year. Our guide to building business credit can also help you eventually qualify for lower-cost financing.
