Receivables Factoring

How it works

A factor buys a business's accounts receivable outright, at a discount to their face value, and ownership of the invoice actually transfers. That transfer is what makes it a sale rather than a secured loan, even though the economics resemble lending. The factor advances a percentage of face value immediately, called the advance rate, and holds the remainder as a reserve, releasing it to the seller, less the factor's fee, once the customer actually pays.

The credit underwritten in this transaction belongs to the account debtor, meaning the customer who owes the money, not to the business that sold the invoice. A factor is betting on that customer's ability and willingness to pay, which is why factoring can work for young or thinly capitalised sellers whose own balance sheet would never clear a bank's underwriting.

Notification factoring tells the customer to pay the factor directly, usually into a lockbox, and is the more common and lower-risk structure. Non-notification factoring keeps the sale confidential from the customer and carries meaningfully more risk of misdirected or diverted payments. Recourse factoring lets the factor charge an unpaid invoice back to the seller; non-recourse factoring has the factor absorb the credit loss, but typically only for defined insolvency events rather than for commercial disputes.

A UCC-1 financing statement is filed to perfect the factor's claim on the receivables, and any existing lender holding a blanket lien on the seller's assets has to subordinate or release its interest first. Verifying that an invoice is genuine, undisputed, and tied to goods or services actually delivered is the operational core of the business and the primary defence against fraud. Individual investors typically reach this space through specialty finance funds, private notes issued by factoring companies, or marketplace platforms; running the operation directly means operating an actual finance business.

What it pays

Factoring economics are quoted as a discount or fee against the face value of an invoice for a stated period, often with additional fees layered on as the invoice ages, rather than as a stated annual interest rate. Because the holding period is short, a modest-looking discount on face value annualises into a far larger figure, which is what makes factoring's headline numbers look striking next to conventional lending.

What drives the return is the credit quality and payment behaviour of the account debtors being factored, the advance rate offered, the concentration of the receivables book, and the seller's historic dilution. Dilution, meaning credit notes, disputes, short payments and returns, is the metric practitioners watch hardest, because it erodes collections without any customer actually defaulting.

Gross return comes from the fee charged plus any float earned while holding collected funds; servicing and collections costs subtract from it, and those costs run higher than in most other forms of lending given the verification and collection work involved. Fund investors receive only the net spread left after loss reserves, servicing costs, and fund-level expenses, so the gap between what a seller pays and what an investor ultimately earns is wide. Non-recourse pricing runs higher than recourse pricing because the factor, rather than the seller, is retaining the credit risk.

Costs and taxes

Running a factoring book directly means absorbing real operating costs: verification staff, collections personnel, credit insurance, servicing software, and legal work on UCC filings and intercreditor agreements with any existing lenders. Fund investors face a second layer, paying management and performance fees on top of the operating costs the fund itself is already bearing internally.

For US federal tax purposes, discount income earned from factoring is ordinary income, not capital gain. A fund organised as a partnership reports its results to investors on a Schedule K-1 rather than a 1099.

Factoring conducted directly constitutes an operating trade or business, which brings self-employment tax considerations, state registration, and in some states specific commercial finance licensing requirements depending on the type of receivable involved. Held inside a self-directed IRA, an active factoring operation generates unrelated business taxable income, because the IRS treats it as an operating business rather than as passive investment income.

Bad debt write-offs and reserve accounting carry more weight here than in most income investments, since charge-offs are a routine, expected part of the business rather than a rare exception. Because a factoring transaction is legally structured as a purchase rather than a loan, state usury caps generally do not apply, but courts have repeatedly litigated whether a given arrangement is truly a sale or a disguised loan subject to recharacterisation.

Liquidity and time commitment

The underlying assets are very short-dated. Invoices commonly turn over within a month or two, so a factoring portfolio self-liquidates quickly if new purchases simply stop being made. That short duration is a structural feature of the asset class, not a promise about any particular fund's terms.

Fund vehicles nonetheless impose redemption notice periods and sometimes gates, because their capital is continuously redeployed into new invoice purchases, and halting that flow means unwinding ongoing client relationships rather than simply waiting for cash to arrive. Direct participation is not liquid in any meaningful sense: it is a business with staff, systems, and customer relationships, and exiting it means selling a business, not redeeming a position.

Effort marks the real dividing line in this asset class. Through a fund, the position is genuinely passive; run directly, it is a full-time credit, verification, and collections operation. Platforms that let investors fund individual invoices sit between the two, but they push the diligence burden back onto the investor, and whatever diversification exists is whatever the investor builds themselves, invoice by invoice.

Factoring relationships with sellers are typically contracted for a fixed term with minimum volume commitments, which stabilises the flow of receivables into a factor's book but also locks the operator into serving that client for the contract period.

How it goes wrong

The classic failure is the fake invoice: invented customers, inflated amounts, or invoices billed for goods that were never actually shipped. Verification, confirming the invoice is real and the underlying delivery occurred, is the only real defence, and any weakness in that process is where fraud enters.

Receivables can be double-pledged, sold to two factors at once, or already captured by an existing lender's blanket lien that was never properly subordinated or released. Dilution is a separate and quieter failure mode: a customer pays less than the invoice states because of a return, a dispute, or a contra account, and the shortfall lands on the factor even though no default has technically occurred. Concentration compounds both problems, since a book built around one large account debtor can be wiped out by that single customer's insolvency.

Recourse back to the seller is only as good as the seller's own solvency, and businesses that turn to factoring are often thinly capitalised to begin with, which limits how much that recourse is actually worth. Non-recourse protection typically excludes the most common real-world cause of non-payment, since commercial disputes are almost always carved out of the coverage.

There is also an adverse selection problem built into the client pool: businesses that qualify for conventional bank credit generally use it, so the applicants seeking factoring skew toward companies a balance sheet lender already declined. Finally, payments a factor collects shortly before a customer's bankruptcy filing can be clawed back by a trustee as a preference, turning a completed collection into a liability months after the fact.
