Invoice Factoring: How It Works and What It Costs

Invoice factoring sells your unpaid invoice to a third party at a discount so you get most of the money now. The advertised fee is a small percentage, which is why it sounds cheap. Annualised it usually is not, and there are two structural details that cost more than the fee.

It is a sale, not a loan

This distinction is not pedantry — it changes what you are agreeing to. In factoring you sell the invoice to a factor. They advance you most of its value immediately, collect the full amount from your client, and release the remainder to you minus their fee. You have not borrowed anything, so there is no interest rate, no repayment schedule, and no loan on your record.

Because it is a sale rather than credit, the consumer lending protections you might expect do not apply, and the "fee" is not required to be presented as an annual rate the way a loan's APR is. That is the single most important thing to know going in: the number in the advertisement and the number you should be comparing against are not the same number, and the industry has no obligation to do the conversion for you.

The mechanics have three parts. The advance rate is the share you get immediately, typically 70% to 90% depending on your industry and your client's credit. The fee is what the factor keeps, usually quoted per 30 days. The reserve is the rest, released when your client actually pays. If your client pays late, most agreements keep charging the fee for the extra time, so a 30-day quote on an invoice that takes 75 days to clear is not a 30-day price.

What it costs once you annualise it

A 3% fee on a 60-day invoice is not 3%. You are giving up 3% of the invoice to be paid roughly 60 days sooner, which works out to an effective annual rate of about 19%. That is genuinely useful context: it is cheaper than the 2/10 Net 30 early-payment discount many freelancers offer without pricing it, which annualises to around 37%, and it is in the same territory as a credit card.

The range matters more than any single figure. Factoring quoted at 1% to 1.5% per 30 days lands around 12% to 19% annualised, which is a reasonable price for solving a real cash-flow gap. Quoted at 3% to 5% per 30 days it lands at 38% to 78%, which is expensive money. The advertised headline is almost always the bottom of the range and assumes a creditworthy client paying on time.

Then there are the charges that are not in the headline. Application or due-diligence fees, monthly minimums whether or not you factor anything, wire fees per advance, and termination fees if you leave inside the contract term. Ask for the total cost on a specific invoice at a specific payment date rather than the rate, and ask what happens to the price if the client pays thirty days late — because they often do, and that is when the real rate reveals itself.

Recourse is where the risk actually sits

Almost all small-business factoring is recourse factoring, which means that if your client never pays, you buy the invoice back. You return the advance, usually with fees on top. The factor took a fee for accelerating your cash, not for absorbing the risk of non-payment.

Non-recourse factoring exists and does transfer that risk, but read what it actually covers. In most agreements it covers your client becoming insolvent, and nothing else. If the client disputes the work, claims it was incomplete, or simply refuses to pay while remaining solvent, that is usually excluded and you are back on the hook. Non-recourse also costs more and requires stronger client credit.

The practical consequence is that factoring does not make a risky client safe. If you have a client you are worried about, factoring their invoice moves the timing of your cash without moving the risk, and it adds a fee. The instrument that addresses a client you do not trust is a deposit before the work starts, not a discount on the invoice afterwards.

Your client finds out, and that has a cost

Most factoring is notification factoring. The factor tells your client that the invoice has been assigned and instructs them to pay the factor directly, usually with a notice printed on the invoice. Your client will know, and they will be paying a finance company rather than you.

How that lands depends entirely on the client. In trucking, staffing and construction it is routine and nobody blinks. In professional services with a small number of relationship-driven clients, some read it as a sign that you are struggling, and one bad reading can cost more than the fee did. This is not a reason to avoid factoring — it is a reason to know which kind of client you have before the notice arrives unannounced.

Non-notification factoring, where the client is not told, exists but is generally reserved for larger and more established businesses. If it is offered to you, check carefully how collection is handled, because the factor still needs to be paid and the mechanism has to sit somewhere.

Most freelancers do not qualify, and nobody mentions that

Factoring companies underwrite your client, not you — they are buying your client's obligation to pay, so it is your client's creditworthiness that matters. That has consequences the marketing pages skip.

Your invoices generally need to be business-to-business or business-to-government. Invoices to individuals are rarely factorable. Your clients usually need to be established companies that pass a credit check, which rules out invoices to other freelancers and to small startups. And most factors have monthly minimums — commonly in the tens of thousands of dollars of invoice volume — that a solo freelancer billing a few thousand a month simply does not reach.

If you are a freelancer with two or three clients and occasional cash-flow gaps, the honest answer is that factoring is probably not available to you, and the things that are available are cheaper anyway: a deposit before work starts, milestone billing so you are never owed the whole project, invoicing on completion rather than at month end, and asking the client when their payment runs happen. The guide on payment terms works through why those beat changing your terms, and they all cost nothing.

Where factoring genuinely earns its place is a specific shape of business — you invoice creditworthy companies on long terms, the volume is steady and substantial, and the gap between doing the work and being paid is structural rather than occasional. Staffing agencies that make payroll weekly and invoice at Net 60 are the textbook case, and for them 19% annualised to bridge a permanent gap is a sensible cost of doing business.

Example

A small design studio invoices a corporate client $12,000.00 on Net 60 terms. They need the cash for payroll in two weeks rather than in two months, and they factor the invoice at an 85% advance rate with a 3% fee for the 60-day period. The client pays on time.

Invoice value	$12,000.00
Advance at 85% — received within days	$10,200.00
Factoring fee — 3% of invoice value	−$360.00
Reserve released when the client pays	$1,440.00
Total received	$11,640.00
Effective annual rate	about 19%

They received $11,640.00 instead of $12,000.00, and had $10,200.00 of it about eight weeks early.

The $360.00 fee is what the whole decision turns on, and 3% reads as small. Annualised it is about 19% — cheaper than the 2/10 Net 30 early-payment discount many freelancers offer without ever pricing it, and roughly comparable to a credit card. For bridging payroll on a real obligation, that is a defensible price. For smoothing a gap that could have been avoided by invoicing on completion, it is not.

The advance is 85%, not 100%. The remaining $1,440.00 sits with the factor until the client actually pays. That matters for planning: the cash available in two weeks is $10,200.00, not $12,000.00, and the reserve arrives on the client's schedule rather than the studio's.

This is a recourse arrangement, which is what almost all small-business factoring is. Had the client not paid at all, the studio would have had to return the $10,200.00 advance and the fee would still have been charged. The factor accelerated the cash; it did not take on the risk of the client failing.

If the client had paid at day 90 instead of day 60, the fee would typically have continued accruing. A 3% quote is priced per period, not per invoice, and the realistic annual rate on an invoice that runs late is materially higher than the headline. Ask for the price at 30, 60 and 90 days before signing anything.

The comparison worth making is not factoring against nothing. It is factoring against the alternatives: a deposit before the work started, milestone billing so the studio was never owed $12,000.00 at once, or invoicing the day the work was accepted. Those cost zero. Factoring is what you use when the gap is structural and the alternatives have already been applied.

Frequently asked questions

Is invoice factoring a loan?: No. You sell the invoice rather than borrowing against it, which is why there is no interest rate, no repayment schedule and no loan on your record. It also means the fee is not required to be disclosed as an annual rate, so the advertised percentage and the number you should compare against other financing are not the same number.
What does invoice factoring actually cost?: Fees are typically quoted at 1% to 5% per 30 days. Annualised that is roughly 12% at the low end and can exceed 70% at the high end. Add application fees, monthly minimums, wire fees and termination charges. Ask for the total cost on a specific invoice at 30, 60 and 90 days rather than the headline rate — late payment is where the real price appears.
What happens if my client never pays?: In recourse factoring, which is most small-business factoring, you buy the invoice back — you return the advance and the fee generally still stands. Non-recourse transfers that risk but usually only covers client insolvency, not disputes or refusal to pay, and it costs more. Factoring changes when you get paid, not whether the client is reliable.
Will my client know I factored their invoice?: Usually yes. Most factoring is notification-based: the factor tells your client the invoice has been assigned and instructs them to pay the factor directly. In trucking, staffing and construction this is routine. In relationship-driven professional services some clients read it as financial distress, so know your client before the notice arrives.
Can a freelancer use invoice factoring?: Often not. Factors underwrite your client rather than you, so invoices generally need to be to established businesses or government that pass a credit check — invoices to individuals or other freelancers are rarely eligible. Most factors also have monthly volume minimums well above what a solo freelancer bills. If you do not qualify, the cheaper levers are a deposit, milestone billing and invoicing on completion.
What are the alternatives to factoring?: In order of cost: taking a deposit before work starts, billing milestones so you are never owed the whole project, invoicing the day work is accepted rather than at month end, and asking when the client runs payments. All cost nothing. An early-payment discount is an option but prices out around 37% a year, which is more expensive than most factoring. A business line of credit is usually cheaper than both if you can get one.
