What Is Invoice Factoring?

Invoice factoring is selling your unpaid invoices to a third party — called a factor — for immediate cash, at a discount. You get money today; the factor collects the full amount from your client later. It's a cash-flow tool, not free money.

How factoring actually works

The mechanics are straightforward. You've invoiced a client $10,000 on Net 30 terms. Instead of waiting a month, you sell that invoice to a factor for, say, $9,500. The factor pays you now, then collects the $10,000 from your client when it's due. The $500 difference is the factor's fee for advancing the cash and taking on the wait.

There are two main structures. In recourse factoring, if your client never pays, the factor can come back to you for the money — you keep the credit risk. In non-recourse factoring, the factor absorbs the loss if the client defaults — but the discount is steeper, because the factor is taking real risk.

Factors also verify your invoices before buying them — they'll confirm the work was delivered and the client acknowledges the debt. You can't factor an invoice the client disputes, and most factors want invoices from creditworthy business clients, not individuals.

What it costs

Factoring isn't priced like a loan with an interest rate — it's priced as a discount on the invoice, typically 1–5% depending on the invoice size, the client's creditworthiness, and how long until payment is due. A $10,000 invoice might net you $9,700 after fees.

Watch for the fee structure beyond the headline discount: application fees, monthly minimums, and charges for invoices that age past certain thresholds. A factor quoting "just 2%" may cost considerably more once the extras stack up. Get the all-in cost in writing before signing anything.

Also note the lock-in: many factoring agreements require you to factor all invoices from certain clients, or commit to a minimum volume, for a contract term. That's fine if your cash flow genuinely needs it — but read the termination terms before you're dependent on the arrangement.

When factoring makes sense — and when it doesn't

Factoring makes sense when you have a timing problem, not a profit problem. Classic cases: you landed a big client with Net 60 terms but payroll hits Friday; you're growing fast and need cash to fund the next job's materials; or seasonal gaps leave you asset-rich and cash-poor.

It makes less sense when the underlying issue is slow invoicing or weak follow-up — selling invoices at a discount to fix a process problem is expensive. Tighten your billing first: invoice same-day, set shorter terms, and run a real follow-up sequence. Our guide to getting paid faster covers the free fixes.

It's also a poor fit for tiny invoices (fees eat the benefit), disputed invoices (factors won't touch them), and consumer clients (most factors only buy business-to-business receivables). And if your clients would be alarmed to hear a third party is collecting from them, consider confidential factoring — where the factor stays invisible — or skip factoring entirely.

Factoring vs. the alternatives

• Business line of credit: usually cheaper than factoring if you qualify — you borrow what you need, repay, and reuse it. But it requires decent credit and takes time to set up.
• Invoice financing (not factoring): similar idea, but you borrow against the invoice rather than selling it — you still collect from the client yourself. Often less awkward client-wise.
• Shorter payment terms: moving clients from Net 60 to Net 15 is free and permanent. The cheapest cash-flow fix is always better terms.
• Deposits and milestone billing: getting paid as work progresses beats financing the gap afterward.

Factoring is a legitimate tool — entire industries run on it — but it's the most expensive way to solve a cash-flow gap. Treat it as a bridge for real timing mismatches, not a substitute for disciplined billing. For the vocabulary, see invoice factoring and cash flow in the glossary.
