How does invoice factoring work?
Invoice factoring works in three steps: you invoice a customer, sell that invoice to a factoring company for an immediate advance of 80–90%, and receive the rest minus a fee when your customer pays. It's how a business gets paid before an invoice comes due.
The three steps
First, you complete the work and invoice a creditworthy commercial customer. Second, you sell the invoice to a factor, which advances most of the value — typically 80–90% — within a day or two. Third, when your customer pays the factor, you receive the reserve balance minus the factoring fee. The factor handles collection in between. Because the factor is really underwriting your customer's ability to pay rather than yours, factoring is reachable even for young businesses that couldn't get a bank line, and it grows automatically as you invoice more creditworthy customers.
What it costs and the recourse question
Factoring fees are charged as a percentage per 30 days the invoice is outstanding, so slow-paying customers cost more — a 2% fee on a 30-day invoice is very different from 2% every 30 days on one that stretches to 90. Recourse factoring is cheaper but you buy back any invoice the customer never pays; non-recourse costs more and moves that credit risk to the factor. Watch for reserve holdbacks and monthly minimums when comparing quotes, because the all-in cost often lives in those details rather than the headline rate.
Recourse vs non-recourse in practice
The choice comes down to who absorbs a bad debt. With recourse, if your customer goes under or simply never pays, you repay the advance — you kept the credit risk in exchange for a lower fee. Non-recourse shifts that risk to the factor, but read the fine print: it usually covers only a customer's insolvency, not a disputed invoice or a slow payer. For a business with a few large customers, non-recourse on the riskier accounts can be worth the premium as insurance against one bad debt wiping out a month's margin. For a diversified book of reliable payers, recourse is often the cheaper, sensible default.
Factoring vs a line of credit
A line of credit is borrowing against your business; factoring is selling an asset you already own — the receivable — so it scales with your sales and doesn't add debt to your balance sheet. If your cash gap is caused specifically by waiting on invoices, factoring targets the cause directly rather than layering a loan on top of receivables you already hold. A bank line is usually cheaper if you can get one, but it's capped at a fixed limit and slow to arrange; factoring is easier to qualify for and grows with your billings. Carriers hauling freight use the same mechanism, called freight factoring.
Who it fits — and who it doesn't
Factoring suits businesses that sell to other businesses on terms: subcontractors billing general contractors, staffing agencies covering payroll before clients pay, wholesalers, and freight carriers. If waiting on invoices — not a shortfall in profit — is what's draining you, it fixes the real problem. It's a poor fit for businesses that sell to consumers, take payment on delivery, or issue only a handful of small invoices a month, where the setup overhead outweighs the benefit. Factoring is a cash-flow tool, not a fix for an operation that loses money on the work itself.
What to check before you sign
Beyond the advance rate and fee, the terms that decide whether factoring works for you are the contract length, any monthly minimum volume you must factor, the notice period to exit, and whether you must factor all invoices or can choose. Reserve holdbacks, monthly account fees, and wire charges add up and are easy to miss next to the headline rate. A long lock-in with a high minimum can trap a business whose needs change; a flexible, spot-factoring arrangement costs a little more per invoice but keeps you in control. Compare the all-in cost and the exit terms, not just the advertised percentage.
A worked example of the numbers
Picture a $10,000 invoice to a solid commercial customer who pays in 45 days, with a factor offering an 85% advance and a fee of 2.5% per 30 days. On day one or two, you receive $8,500 — cash you can put straight into payroll or materials. Forty-five days later the customer pays the factor the full $10,000. The fee works out to roughly 2.5% for the first 30 days plus a partial charge for the remaining 15, so call it about $375 total; the factor releases the $1,500 reserve minus that fee, so you net around $1,125 more, for $9,625 in hand on a $10,000 invoice. Whether that's a good deal depends on what the early $8,500 let you do — take another job, hit payroll, keep a supplier discount — versus simply waiting 45 days. Run your own numbers with your real advance rate, fee, and customer payment speed, because a fast-paying customer makes factoring cheap and a chronically slow one makes it expensive.
Frequently asked questions
- How long does factoring take to set up?
- Initial approval commonly takes a few days since the factor is assessing your customers' credit. After that, individual invoices can fund same-day or next-day.
- Will my customers know I factor?
- Usually yes, because the factor collects payment directly and remits to a factoring lockbox. Some non-notification arrangements exist but are less common and cost more.
- Does factoring add debt to my balance sheet?
- No. You're selling an asset — the invoice — rather than borrowing against it, so it doesn't add debt the way a loan or line of credit does, and it scales with your sales.
