Invoice Factoring: Complete Guide for Small Businesses

Invoice factoring is one of the oldest forms of business finance — it predates modern banking by centuries. For B2B businesses with outstanding invoices and cash flow gaps, it remains one of the most efficient ways to access working capital without taking on traditional debt.

How Invoice Factoring Works, Step by Step

You complete work and invoice your client for, say, $100,000 net-60. Rather than waiting 60 days, you sell that invoice to a factoring company. The factor verifies the invoice with your client, advances you 80–90% of the invoice value immediately (so $80,000–$90,000), and takes responsibility for collecting payment from your client.

When your client pays the full $100,000 at day 60, the factor remits the remaining balance to you — minus their fee, typically 1–5% of the invoice value per 30-day period. Your net receipt on a $100,000 invoice with a 2% monthly fee and 90% advance: $88,000 total ($90,000 advance + $8,000 remainder, minus $2,000 fee on 30 days + $2,000 on 60 days).

Recourse vs. Non-Recourse Factoring

In recourse factoring — the most common type — if your client doesn't pay the invoice, the factor can require you to buy it back or replace it with another invoice. You bear the credit risk of your clients' non-payment. Fees are lower because the factor's risk is lower.

In non-recourse factoring, the factor absorbs the loss if your client defaults. This protects you from client non-payment, but fees are higher and factors are more selective about which clients' invoices they'll accept. Non-recourse factoring is most valuable when you have clients with uncertain creditworthiness — it's essentially credit insurance built into the financing.

What Factors Look for When Evaluating Applications

Invoice factoring underwriting is almost entirely about your clients' creditworthiness, not yours. The factor is essentially extending credit to your client — they need to know your client will pay. This means they'll verify your client is a legitimate business, check for any public records issues (liens, judgments, bankruptcies) on your client, and confirm the invoice is for goods or services already delivered (factors don't advance on future deliverables).

Your business's credit score matters less than in traditional lending — which is why factoring is available to startups and businesses with credit challenges that can't access other products. What they do care about: the invoice is legitimate, deliverables are complete, and there are no disputes between you and your client.

Factoring vs. Invoice Financing: An Important Distinction

Invoice factoring and invoice financing are often confused but they're different products. In factoring, you sell the invoice — the factor owns it and collects from your client. In invoice financing (also called accounts receivable financing or invoice discounting), you borrow against the invoice as collateral, but you retain ownership and continue collecting from your client.

With invoice financing, your clients are never notified — the relationship stays between you and them. With factoring, the factor contacts your client to verify the invoice and direct payment to themselves. For businesses where client relationships are sensitive, invoice financing (keeping the process confidential) may be preferable even if rates are slightly higher.
