What Is Invoice Factoring? The Real Cost and the Lien

If you sell to other businesses on net-30, net-60, or net-90 terms, you have already discovered the core problem of B2B: you can be profitable and broke at the same time. The work is done, the invoice is out, and the money shows up two months later. What is invoice factoring? It is the financial product built specifically for that gap — you sell your unpaid invoices to a third party at a discount and get most of the cash within a day or two instead of waiting for your customer.

The part most articles bury is that invoice factoring is not a loan. Legally and mechanically, it is a sale of an asset. You are not borrowing against your receivables; you are selling them. That distinction drives everything else about how the deal is priced, who gets underwritten, and — the part that costs business owners the most money — what gets filed against your company in the public record afterward.

What invoice factoring actually is

A factoring company (the "factor") buys your accounts receivable. You hand over an invoice with a face value of $10,000. The factor wires you an advance — typically 70% to 90% of face value, so $8,500 at a common 85% advance rate. It then holds the remaining $1,500 as a reserve. When your customer pays the invoice in full, the factor releases the reserve to you minus its fee.

Three parties, not two: you, your customer, and the factor. Your customer becomes the factor’s collection target. That is the structural difference between factoring and a line of credit, and it is why factoring is available to companies no bank will touch.

How invoice factoring works, transaction by transaction

1. You deliver the goods or complete the service and issue an invoice to your business customer on standard terms — net-30, net-60, whatever you normally use.
2. You submit that invoice to the factoring company, usually with backing documentation: the purchase order, proof of delivery, signed bill of lading, or a signed work order.
3. The factor verifies the invoice. It confirms with your customer that the work was completed, the amount is correct, and there is no dispute. This step is why factoring works — the factor is confirming a real, collectible obligation exists.
4. The factor runs credit on your customer, not on you. It pulls the customer’s commercial credit file and payment history to decide whether that specific receivable is worth buying and at what advance rate.
5. A notice of assignment goes out. In standard (notification) factoring, your customer receives a formal letter stating the invoice has been assigned and all payments must now go to the factor’s lockbox or account.
6. The factor advances you the agreed percentage — commonly 80% to 90%, and up to 95% in low-risk sectors like freight — usually within 24 to 48 hours of approval.
7. The factor files a UCC-1 financing statement with your state to perfect its security interest in the receivables. This is not optional for the factor, and it happens whether or not anyone explains it to you.
8. Your customer pays the factor directly on the original due date.
9. The factor releases the reserve to you, subtracting its factoring fee — priced as a percentage of the full invoice face value, per 30 days the invoice stayed outstanding.
10. If the customer never pays, what happens next depends entirely on one word in your contract: recourse.

Recourse vs non-recourse — who eats the loss

Recourse factoring means you do. If your customer fails to pay within the recourse period (often 60 to 90 days past due), you must buy the invoice back from the factor at full face value, or the factor claws the advance out of your next funding. You keep the credit risk. Recourse deals are cheaper because of it.

Non-recourse factoring means the factor absorbs the loss — but read the carve-out carefully, because it is almost never as broad as the marketing implies. Non-recourse typically covers only your customer’s credit-based insolvency: they go bankrupt or become verifiably unable to pay. It does not cover disputes. If your customer refuses to pay because the shipment was short, the work was defective, or there is a billing disagreement, that is a dispute, not an insolvency, and the invoice comes right back to you. Non-recourse also carries a higher fee and stricter customer credit screening.

Practical translation: "non-recourse" is credit insurance on your customer’s solvency, not a guarantee that you keep the money no matter what.

What invoice factoring actually costs

The advertised number is the discount rate, quoted as a percentage of invoice face value per 30 days. Published ranges run 1% to 5% per 30 days, with most of the market clustering near 2.5% for the first 30 days. Many factors use tiered schedules that escalate — for example 2.75% for days 1-30, 3.75% for days 31-45, 5.5% for days 46-60, and 8.25% past 60.

That "3%" sounds like a rounding error next to a bank rate. It is not, for two reasons. First, the fee is charged on the full invoice face value, but you only received 85% of it. Second, the period is 30 days, not a year. Annualize it correctly and the picture changes. The formula: (fee divided by cash actually advanced) multiplied by (365 divided by days the invoice was outstanding).

All figures assume an 85% advance rate. At a 90% advance the APRs drop roughly six points; at 80% they rise by about the same.

The UCC-1 lien is the part that costs you later

Here is the mechanic almost nobody explains before you sign. To protect its purchase, the factor files a UCC-1 financing statement with your Secretary of State. Under Article 9 of the Uniform Commercial Code, a sale of accounts is a secured transaction — the factor must file to perfect its interest and establish priority. Filing fees are trivial, roughly $20 to $50 in most states. The consequences are not. If you have not read what a UCC filing is and what it does to your fundability, read that before you sign a factoring agreement.

Two versions exist, and the difference is worth thousands of dollars to you:

• A receivables-only lien names accounts receivable and the proceeds of those receivables as collateral. It does not encumber your equipment, inventory, or general intangibles. Equipment loans and asset-backed SBA financing can usually still be written around it.
• A blanket lien names all assets. Receivables, equipment, inventory, intangibles, everything. Many factors default to this because it reduces their risk, not because the deal requires it.

A blanket UCC-1 shows up in every lender’s collateral search. A bank underwriting a line of credit sees that your assets are already pledged and either declines, prices you as a subordinate creditor, or demands a subordination agreement from the factor. The factor is under no obligation to sign one — and even when it will, expect two to four weeks of back-and-forth. Stacked filings compound the problem: multiple active UCC-1s signal a business that has already pledged everything it owns.

The filing does not expire when your factoring relationship does. A UCC-1 is effective for five years from the filing date under UCC section 9-515, and it lapses only if nobody files a continuation in the six-month window before that date. When you exit a factoring contract, the factor is supposed to file a UCC-3 termination. It does not always happen automatically. You have the right to send an authenticated demand for termination, and the secured party generally must file or send the termination within 20 days. Then budget another 5 to 10 business days for the public record to update and 30 to 90 days for business credit files to catch up.

Factoring underwrites your customers, not you

This is the reason factoring exists as a category. A bank underwrites your business: time in business, revenue, debt service coverage, your personal FICO, your business credit file. A factor underwrites the creditworthiness of whoever owes you money.

If you are an 11-month-old staffing company with a 580 personal score and you invoice a Fortune 500 logistics firm on net-60, a bank says no and a factor says yes. The factor is not betting on you. It is betting on the buyer’s payment history, and it holds a verified invoice plus a legal assignment as its security.

Most factors will still look at you — a background check, a light credit pull for fraud screening, a UCC search for existing liens, sometimes a personal guarantee covering fraud and disputed invoices. But it is a fraud and eligibility check, not a credit decision. That is why factoring approvals happen in days when bank applications take weeks. The trade-off: your customer concentration and your customers’ credit become your ceiling.

Notification vs non-notification, and spot vs whole-ledger

Notification factoring is the default. Your customer gets a notice of assignment and pays the factor directly. Non-notification (sometimes called confidential factoring) keeps your customer in the dark — payments route to a lockbox that appears to belong to you. It costs more and the qualification bar is much higher, commonly two or more years in business and substantial monthly volume. If your concern is that customers will read a notice of assignment as financial distress, ask specifically about non-notification on your first call rather than assuming it is available.

Spot factoring means you pick individual invoices to sell — maximum flexibility, higher per-invoice rate. Whole-ledger factoring means you assign all or nearly all receivables at a lower rate, but you are locked into a term. The obligations underneath are easy to skim past:

• Monthly volume minimums, commonly $5,000 to $25,000 or more in invoices per month — fall short and you pay the fee on the shortfall anyway.
• Auto-renewal clauses that roll the contract forward unless you give written notice, often 60 to 90 days before the term ends.
• Early termination or buyout fees for exiting before the term expires.
• One-time setup and due-diligence charges, commonly $500 to $2,500, plus per-transaction ACH or wire fees of roughly $15 to $50.

Does factoring build business credit?

Generally, no. Factoring is a sale, not a loan, so the factor is not reporting a tradeline with a balance and payment history the way a business credit card or term loan does. What does appear is the UCC-1 filing. So the net effect of a year of factoring can be zero credit-building upside and one visible lien on the downside.

The indirect benefit is real but secondhand: the cash lets you pay your vendors and net-30 accounts on time, and those vendors — if they report — build your file. That asymmetry is the strategic case for treating factoring as a bridge rather than a permanent capital structure. If you want the tradelines that actually do report, start with the verified net-30 vendor list.

How to pressure-test a factoring offer

• Get the fee schedule in writing with every tier, and calculate the effective APR at your actual average days-to-pay, not the best-case tier.
• Ask directly whether the UCC-1 is receivables-only or all-assets. Get the answer in the contract, not on a call.
• Ask whether the factor will sign a subordination agreement for a future lender, and under what conditions.
• Read the recourse period and the dispute carve-out in any non-recourse deal.
• Add up the monthly minimum, setup fee, wire fees, and termination fee, then divide by expected annual volume to get your real rate.
• Confirm the UCC-3 termination process and timeline in writing before you sign, not when you leave.

Factoring is the symptom. This is the cause.

The reason a 40% effective APR looks acceptable is that the alternatives — a bank line at 8% to 12%, a real business credit card, trade lines with net-30 terms — are unavailable to you right now. They are unavailable because of a fundability profile most owners have never actually seen: entity structure, business credit file completeness, bureau listings, existing liens, and how your business reads to an automated underwriter before a human opens the file.

That profile is measurable, and most of what blocks it is fixable in weeks rather than years. Find out which pieces you are missing before the next cash crunch forces the decision for you — because the cheapest time to fix a fundability problem is always before you need the money.
