Factoring is running one merchant's transactions through a different merchant's account to hide where the sales really come from. It is a form of transaction laundering that lets a banned, high-risk, or undisclosed business hide behind a clean-looking account and slip past underwriting and monitoring.
What is factoring, in plain English?
In payments fraud, factoring means processing a business's card sales through a merchant account that belongs to someone else. The account that gets approved and monitored is not the one that actually generated the sales. The real business, which might be selling something the acquirer would never knowingly board, sits hidden behind a front that looks ordinary.
This is a species of transaction laundering. The point is to defeat underwriting: a merchant that could not pass its own application borrows the identity of one that did, and its transactions flow through a clean-looking pipe. The acquirer sees the front's approved business and misses the true source of the money.
Factoring is both a fraud and a compliance problem. It exposes the acquirer to unexpected chargebacks and legal risk from the hidden business, and it defeats the monitoring that is supposed to keep prohibited or high-risk activity off the network.
How factoring works
- Front — Board a clean merchant. A benign, approvable business gets a legitimate merchant account, or an existing one is repurposed.
- Hide — Route the real sales. Transactions from the undisclosed or banned business are pushed through the front's account.
- Blend — Disguise the descriptor. Statements show the front's name, so cardholders and monitors see goods that were never really sold.
- Extract — Settle out the funds. Money settles to the front and is passed to the true operator, minus a cut for the account holder.
Who is involved?
Who | Their role |
The hidden merchant | The real business, often banned or high-risk, whose sales are being disguised. |
The front account | A clean, approved merchant lending its account, whether complicit or duped. |
The acquirer | Boards and monitors the front, unaware of the true source of the volume. |
The cardholder | Sees an unfamiliar descriptor and may dispute, surfacing the mismatch. |
What it looks like in practice
In practice
A small online retailer of home goods was boarded months ago with modest, steady volume. Then its processing jumps sharply, average ticket sizes change, and a share of its buyers are in regions that make no sense for a domestic housewares shop. Chargebacks arrive citing products the retailer does not sell.
A review finds the account is being used to process payments for a separate, prohibited business that could never have been boarded on its own. The housewares merchant is factoring: its clean account is a pipe for someone else's sales, and the descriptor mismatch on the disputes is what finally gave it away.
Why it matters to operators
Factoring quietly breaks the whole point of underwriting. An acquirer's risk model assumes it knows what each merchant sells, but a factored account carries hidden volume with a completely different risk profile, sometimes from businesses that are illegal or under sanction. The exposure shows up later as surprise chargebacks, fines, and potential liability for facilitating prohibited activity.
Because the true business is deliberately concealed, the usual monitoring signals are muddied. The defense is to watch for mismatches: a descriptor that does not fit the sales, transaction sizes or geographies that do not match the stated business, and volume that jumps beyond what the boarded merchant could plausibly produce.
What to watch in the data
- Descriptor mismatch. Statement text or product descriptions that do not match what the merchant was approved to sell.
- Profile drift. Ticket sizes, categories, or buyer locations that do not fit the boarded business model.
- Volume spikes. Sudden jumps beyond what the merchant's stated operation could realistically generate.
- Odd geography. A large share of buyers in regions inconsistent with the merchant's supposed customer base.
- Chargeback themes. Disputes referencing goods or services the merchant does not actually offer.
Quick questions
Is factoring the same as transaction laundering?
Factoring is a specific form of transaction laundering: routing one business's sales through another's merchant account. Transaction laundering is the broader category of disguising the true source of card payments.
Is the front account always in on it?
Not always. Sometimes the account holder is complicit and takes a cut, and sometimes a legitimate merchant is compromised or duped into processing another party's transactions without fully understanding it.
Why is it a compliance issue, not just fraud?
Because it defeats underwriting and can put prohibited, sanctioned, or illegal businesses onto the payment network unseen. That exposes the acquirer to regulatory and legal risk on top of financial loss.
How is factoring usually discovered?
Through mismatches: descriptors that do not fit the sales, volume that outpaces the stated business, buyer geographies that make no sense, and chargebacks for products the merchant does not sell.
Does note that factoring means something different in lending?
Yes. In finance, factoring is selling receivables for cash, a legitimate practice. In payments fraud, it means disguising a hidden merchant's sales through another account, which is not the same thing.
What should a team do when it suspects factoring?
Investigate the true source of the volume, freeze or offboard the account if confirmed, and consider whether the hidden business triggers reporting obligations given what it is actually selling.
