The direct answer

A notice of assignment tells the account debtor that an identified freight receivable has been assigned and directs payment to the assignee. Under UCC §9-406, payment rights generally change after effective authenticated notice, subject to the statute and other applicable law. The operational priority is a verified, documented remittance change—not a vague email that could be mistaken for payment fraud.

What UCC §9-406 says

The account debtor generally may discharge its obligation by paying the assignor until it receives authenticated notification that reasonably identifies the assigned amount or right and directs payment to the assignee. After effective notice, payment to the wrong party may not discharge the obligation. If requested, the assignee must seasonably furnish reasonable proof of assignment or the account debtor may continue paying the assignor under the rule.

Design a fraud-resistant notification

Use contact information already verified through contracts, portals, or independent records. Avoid approving a bank change solely from the same message that requests it. Record the callback, sender authority, effective date, covered invoices, remittance account, and acknowledgment. Train staff to escalate conflicting instructions.

Handle partial, disputed, and future invoices

The notice should reasonably identify what is assigned. Clarify whether it covers named invoices, an account, or future receivables under the agreement. Keep disputes and offsets visible; assignment does not erase valid defenses. Route short-payments and claims through the contract’s resolution process.

Plan for termination and withdrawal

When factoring ends, outstanding assigned invoices may continue to be serviced by the assignee. Document who sends updated remittance instructions, when they become effective, how proof is delivered, and how final reserves are reconciled. Do not tell customers to redirect payment until the contractual and legal authority is clear.

Use a controlled notice record

Create a record with the assignor, assignee, account debtor, covered invoice or account, authenticated notice, effective date, delivery channel, recipient, proof request, verification callback, acknowledgment, and current remittance instruction. Restrict edits and retain prior versions. The record allows accounting to answer why a payment direction changed and which evidence supports it. It also helps resolve conflicting notices without relying on memory or a forwarded email.

Respond to a request for proof

Route the request to the contract owner and assignee, confirm the requester's identity through a known channel, and provide only the reasonable proof authorized for disclosure. Record the response and deadline. Do not improvise legal conclusions or expose unrelated customer data. If the scope of the assignment or notice is unclear, obtain qualified advice before directing payment. UCC §9-406 supplies the legal framework, while the agreement and facts determine the appropriate document and response.

Reconcile payments sent to the old account

Identify the invoice, notice delivery date, payment date, destination, and contractual rights before asking anyone to resend money. Preserve bank and customer evidence, notify the assignee under the agreed procedure, and avoid making unsupported statements about double liability. Update controls only after determining why the old instruction was used. The correct response depends on effective notice, proof, the underlying obligation, and applicable law, so operational urgency should not replace factual and legal review.

Train the accounts-payable team

Give staff a concise escalation rule for new or conflicting payment instructions: stop the change, verify the requester through a previously controlled contact, compare the invoice scope, request proof when appropriate, and record the decision. Limit bank-detail changes to authorized users and review logs. The training should not ask staff to make legal judgments; it should show when to involve contract owners or counsel. Repeat the exercise with a realistic spoofed email so the documented control is tested before a genuine notice or fraud attempt arrives.
