Invoice Factoring: How It Works, What It Costs, and When It Makes Sense

Invoice factoring is a financing arrangement in which a business sells its unpaid invoices to a third-party company — called a factor — in exchange for immediate cash. The factor advances a percentage of the invoice value upfront, typically 80–90%, collects payment directly from the end customer, and remits the balance minus its fee once the invoice is paid.

It is not a loan. There is no debt on the balance sheet. It is a sale of a receivable at a discount.

That distinction matters, and so does the cost. Invoice factoring is one of the more expensive forms of short-term financing in B2B, and the situations where it makes genuine sense are narrower than the marketing for it suggests.

What Is Invoice Factoring?

Invoice factoring is the process of selling accounts receivable to a factoring company in exchange for immediate liquidity. A business delivers goods or services, issues an invoice with net payment terms, and instead of waiting 30, 60, or 90 days for the customer to pay, sells that invoice to a factor who advances most of the value immediately.

The factor takes on the collection function. Your customer pays the factor directly, not you. Once the invoice is paid in full, the factor sends you the remaining balance minus the discount fee.

A common arrangement: a factor advances 85% of the invoice value upfront. Once your customer pays the invoice, the factor remits the remaining 15%, minus a factoring fee of 1–5% of the original invoice, depending on invoice size, customer creditworthiness, payment terms, and your overall volume with the factor.

How Invoice Factoring Works, Step by Step

1. You deliver goods or services to your customer and issue an invoice.
2. You sell that invoice to a factoring company, providing documentation of the underlying transaction.
3. The factor verifies the invoice and advances 80–90% of the face value, typically within 24–48 hours.
4. Your customer is notified to remit payment to the factor.
5. When your customer pays, the factor remits the remaining balance minus the factoring fee.

Some factors handle customer notification quietly. Others are highly visible. Clarify this before signing.

Recourse vs. Non-Recourse Factoring

This distinction determines who absorbs the loss if your customer does not pay.

Recourse factoring means you are responsible if the customer defaults. If the factor cannot collect, you buy the invoice back or replace it with another. Most factoring arrangements are recourse. Lower fees, more risk on your side.

Non-recourse factoring means the factor absorbs the credit risk if the customer becomes insolvent. Non-recourse fees are higher, and non-recourse protection is usually narrower than it sounds — it typically covers commercial insolvency (bankruptcy) but not disputed invoices, payment delays, or any circumstance short of formal insolvency. Read the contract carefully. Non-recourse protection rarely covers the scenarios where you actually need it.

What Invoice Factoring Actually Costs

The fee structure in factoring is designed to look small on a per-invoice basis. It is not small on an annualized basis.

A 2% factoring fee on a Net 30 invoice annualizes to roughly 24% APR. A 3% fee on a Net 60 invoice annualizes to roughly 18%. These numbers depend on the exact fee structure and how quickly your customers pay, but the point holds: factoring is an expensive form of short-term financing. It is not free working capital.

Additional costs to verify before signing:

• Minimum volume requirements — some factors require a monthly minimum dollar amount of invoices, with fees charged even if you do not meet it
• Monthly maintenance fees — an administrative charge regardless of volume
• Due diligence fees — setup costs charged at origination
• Concentration limits — restrictions on how much of your factored volume can come from a single customer, with penalties if you exceed them
• Reserve holdbacks — factors sometimes hold additional reserves beyond the initial advance against potential disputes

The effective cost of factoring is rarely just the stated discount rate. Model the full cost on your actual invoice mix before committing.

What Factoring Is Actually Used For

Invoice factoring solves a specific problem: you have verified receivables from creditworthy customers, you need cash before those invoices are due, and you cannot or do not want to borrow against them conventionally.

It is most commonly used by staffing companies (weekly payroll against 45–60 day customer payment terms creates a structural cash flow gap that factoring fills), trucking and freight companies (carriers face 30–60 day payment terms from brokers while fuel costs are immediate), manufacturers and distributors with long production cycles, and early-stage businesses that do not yet qualify for conventional credit lines but have strong, creditworthy customers.

What factoring is not good for: improving margins, reducing operating costs, or fixing a collections problem. If your customers are not paying because they are struggling financially, factoring transfers the problem to the factor but does not resolve it — and in a recourse arrangement, that risk comes back to you.

Invoice Factoring vs. Asset-Based Lending

Both use receivables as a financing mechanism. The structure is different.

In invoice factoring, you sell invoices. The factor owns the receivable and collects directly from your customer. In asset-based lending, you borrow against the value of your receivables as collateral. You retain ownership and continue collecting from your customers. The lender is repaid from your operating accounts, not directly from your customer.

Asset-based lending typically carries lower effective rates than factoring and keeps your customer relationships intact — your customers never interact with the lender. The tradeoff is stricter eligibility criteria and a lending covenant structure that factoring does not have. Asset-based lending is generally better for established businesses with stable receivables. Factoring fits businesses that cannot qualify for conventional credit lines or need speed over cost.

Invoice Factoring vs. Trade Credit Insurance

These solve different problems. Factoring converts future receivables into immediate cash. Trade credit insurance protects against non-payment by covering a percentage of the receivable if a customer defaults.

Factoring provides liquidity. Insurance provides protection against credit loss. A business might use both — factor invoices for cash flow and insure the receivables portfolio against catastrophic single-account default. Or neither, depending on the cash flow profile and customer risk concentration.

What Factoring Tells You About Your Customer

Credit teams should know when a customer is using factoring, particularly if you are on the receiving end.

When a customer factors their own receivables from you, they are telling you something about their cash position. It does not necessarily mean distress — many well-run businesses use factoring as a structural tool in industries where long payment terms are standard. But a customer who recently started factoring after years of not doing so warrants a closer look in your credit review, the same way a new UCC lien filing would.

The more directly relevant scenario for your AR team: a vendor who supplies your customers factors invoices issued to those customers. You may receive a notice of assignment instructing you to remit payment to a third party rather than the original vendor. Honor these notices. Paying the original vendor after receiving a valid notice of assignment does not discharge the debt — you may be required to pay twice. Build notice-of-assignment verification into your accounts receivable management workflow.

When to Factor and When Not To

Factor when the cost of the cash flow gap is greater than the cost of factoring. If you are turning down orders because you cannot fund production, or paying late fees on payables because your receivables have not cleared, factoring may be cheaper than the alternative.

Do not factor as a substitute for fixing a collections problem. If the reason you need cash early is that customers are slow to pay, you have a collections issue and a credit policy problem — not a factoring need. Factoring does not improve customer payment behavior. In a recourse arrangement, the slow-pay risk comes back if the customer defaults.

Do not factor as a permanent solution to a structural margin problem. Paying 18–24% annualized to access your own receivables compresses margins over time. If factoring is a long-term fixture of your cash flow, model whether conventional credit lines or operational changes would be less expensive.

How Factoring Affects DSO

When you factor an invoice, it typically leaves your accounts receivable the moment you receive the advance. This can improve your reported days sales outstanding (DSO) — not because your customers are paying faster, but because the receivable is gone from your books. If you are comparing DSO across periods or against benchmarks, note whether factored receivables are excluded from the calculation. A DSO improvement driven by factoring is a financing decision, not a collections improvement.

Frequently Asked Questions

What is invoice factoring?

Invoice factoring is the sale of unpaid customer invoices to a third-party financing company (a factor) in exchange for immediate cash. The factor advances most of the invoice value upfront, collects payment from the customer, and remits the balance minus a fee.

Is invoice factoring a loan?

No. Invoice factoring is a sale of an asset — the receivable — not a loan. The advance does not appear as debt on your balance sheet. This distinguishes factoring from asset-based lending, where you borrow against receivables as collateral.

What percentage of an invoice does a factor advance?

Most factors advance 80–90% of the invoice face value upfront. The remainder, minus the factoring fee, is remitted once your customer pays. The advance rate depends on your industry, the creditworthiness of your customers, and your relationship with the factor.

What does invoice factoring cost?

Factoring fees typically range from 1–5% of the invoice value, depending on invoice size, payment terms, and customer credit quality. Additional fees can increase the effective cost significantly. On a Net 30 invoice with a 2% fee, the annualized cost is roughly 24%.

What is the difference between recourse and non-recourse factoring?

In recourse factoring, you are responsible if your customer fails to pay — the factor can require you to buy back the invoice. In non-recourse factoring, the factor absorbs the credit risk if your customer becomes insolvent. Non-recourse protection usually covers only formal insolvency, not late payment or disputes, and carries higher fees.

How does invoice factoring affect my customer relationships?

In most factoring arrangements, customers are notified that invoices have been assigned to a factor and instructed to pay the factor directly. Some factors handle this discreetly; others do not. If maintaining direct billing appearances matters for your customer relationships, clarify notification handling before signing.
