Wondering whether your customers will know you factor invoices? In notification vs non-notification factoring, the difference is whether the customer is told to pay the factor. Notification tells them; non-notification does not, and the rules vary by country and provider.
This page is one part of the wider topic of invoice factoring, looked at from the customer-notice angle.
| Item | Key fact |
|---|---|
| Notification factoring | The customer is told its receivables were assigned and is asked to pay the factor directly |
| Non-notification factoring | The customer is not told; the seller often keeps collecting on the factor’s behalf |
| US rule (UCC Article 9, § 9-406) | After proper notice, the customer must pay the factor to be discharged |
| Ontario rule (PPSA Section 40(2)) | The customer may pay the client until it receives notice of assignment |
| Ending a notice | Keep paying the factor until a release letter is received |
The figures and rules above come from the Torkin Manes briefing and the FreightWaves notice of assignment guide. Laws and practices can change, so check the source before you rely on them.
How the two structures differ
A factoring agreement may be on a notification or a non-notification basis, as a Torkin Manes briefing of March 2017 puts it. That briefing describes Ontario law, so treat it as one jurisdiction’s example rather than a universal rule.
On a notification basis, the customer is told about the purchase of the receivables and their assignment to the factor. One purpose of that notice, the same briefing explains, is to require the customer to pay the factor directly instead of the client.
On a non-notification basis, the customer is not told. An August 2019 Financier Worldwide briefing on New York law says companies often sell their receivables and continue to collect the amounts due from customers on behalf of the buyer.
| Question | Notification | Non-notification |
|---|---|---|
| Is the customer told of the assignment? | Yes | No, often until a default |
| Where does the customer send payment? | To the factor | To the seller, who collects on the factor’s behalf |
| Does the customer see the factor’s details? | Yes, in the notice | Not usually |
The comparison above draws on the FreightWaves notice of assignment guide and the Torkin Manes briefing.
What a notice of assignment does legally
A FreightWaves guide dated February 2026 describes a notice of assignment (NOA) as a document that tells your customer to send invoice payments to a factoring company instead of you.
The same guide says that under UCC Article 9, a customer who receives an authenticated notice must pay the factor to be discharged from its obligation. It cites UCC § 9-406 and adds that paying the original supplier after proper notice generally does not discharge the debt.
Ontario words the rule a little differently. The Torkin Manes briefing of March 2017 says Section 40(2) of the PPSA lets the customer pay the client until it receives notice that the receivables have been assigned.
Before notice arrives, then, the customer can lawfully keep paying the seller. The Financier Worldwide briefing of August 2019 quotes the US rule as allowing payment to the assignor until, but not after, the customer receives a notification.
Why non-notification arrangements exist and where they stop
The Financier Worldwide briefing of August 2019 says notice is often not provided until there is a default by the seller. It gives two reasons: the seller does not want customers to know it is using receivables to finance its business, and it may collect better because of close business ties. See the full briefing for the context.
Staying quiet has limits, and the sources point to several:
- An Equipment Finance Advisor article of May 2015 says that without effective notice, the customer may keep paying the seller and may raise defenses and claims that accrued even after the assignment.
- A Triumph post dated June 2017 answers “Short answer is No” to whether a customer must pay a factor when no notice of assignment has been received.
- The same Triumph post says security interests establish priority among secured creditors but do not affect where payment goes.
Registration is a separate step from notice. The Torkin Manes briefing of March 2017 says an Ontario factor must register a financing statement against the client under the PPSA, and the Financier Worldwide briefing of August 2019 says a US sale of receivables is recorded by filing a UCC financing statement. Neither of those filings, on its own, tells the customer where to pay.
What makes a notice effective?
A Frost Brown Todd article of April 2020 quotes UCC 9-406 as making a notification ineffective if it does not reasonably identify the rights assigned. A notice that is vague can therefore fail.
An Equipment Finance Advisor article of May 2015 reviews a Maryland federal court decision involving a factor. The court found a letter legally insufficient because it was vague and did not reasonably identify the rights assigned.
The same Equipment Finance Advisor article advises a separate written communication that identifies the collateral and the parties. It says an assignee should not rely on new invoices listing its address, or on telling the customer in conversation.
Ontario has no fixed template either. The Torkin Manes briefing of March 2017 says the PPSA sets out no statutory form of notice. It reviews the Ontario court case RPG Receivables Purchase Group Inc. v. Krones Machinery Co. Limited, cited as 2010 ONSC 2372, in which the judge had to decide whether a notification was adequate.
A Triumph post of June 2017 adds that a notice can be an invoice stamp, a separate letter, or both. The FreightWaves guide of February 2026 lists these delivery routes that leave a record:
- Certified mail: registered or certified mail with return receipt documents delivery and who signed.
- Secure email: a platform that captures acknowledgment or e-signature gives time-stamped proof.
- Vendor portal: uploading to the customer’s accounts payable portal, with written confirmation, so the change reaches their vendor file.
A customer can also ask for proof. The Torkin Manes briefing of March 2017 says that if the factor fails to furnish proof of the assignment within a reasonable time, the customer may pay the client.
What it means for the client and the customer
If you are the customer
- A notification does not change the amount owed, the account terms, or rights such as a discount for returned goods, according to the Frost Brown Todd article of April 2020.
- The Triumph post of June 2017 says to never stop sending payments to the factor until you receive a release letter.
- The FreightWaves guide of February 2026 says that if a customer pays the wrong party after being notified, the factor can ask the supplier to repay or go after the customer directly.
If you are the client
The trade-off is between keeping the arrangement private and giving the factor a clear legal route to payment. Which structure applies depends on the agreement, the provider and the country, and the sources above cover only US and Ontario examples.

Frequently asked questions
What is non-notification factoring?
Show answer
It is a factoring arrangement in which the customer is not told that its invoice was assigned. The Financier Worldwide briefing of August 2019 says the seller often keeps collecting from customers on the buyer’s behalf.
Does a customer have to pay a factor that never sent notice?
Show answer
The Triumph post of June 2017 gives a short answer of no. Rules differ by country, so check the law that applies to you.
Does filing a financing statement redirect payment?
Show answer
According to the Triumph post of June 2017, a security interest establishes priority among secured creditors but does not affect payment remittance. Payment follows effective notice of the assignment.
Can a customer ask for proof of the assignment?
Show answer
Yes, according to the Torkin Manes briefing of March 2017, which says the factor must furnish proof within a reasonable time if the customer asks. If it does not, the customer may pay the client.
