Debtor notification

A notice telling the customer to pay the factor directly.

Why it matters

Proper debtor notification ensures payment is directed to the factor lockbox rather than the seller operating account. Without effective notification, customers may continue paying the seller directly, creating misdirected fund situations that delay factor settlement and require the seller to forward payments. In notification factoring, the notice is legally significant: it establishes the factor right to collect directly from the account debtor under UCC Section 9-406. An ineffective notice—wrong address, wrong contact, or wrong form—may not legally bind the account debtor to pay the factor.

How it appears in contracts

Debtor notification requirements appear in the Assignment or Notice provisions of the factoring agreement. The agreement specifies who sends the notification, the form it must take, and the timing relative to the assignment of the receivable. Some agreements require notification before or at the time of invoice delivery; others permit it within a defined window after the invoice is submitted for funding. Sellers should document all notifications sent and retain proof of delivery in case the factor or a court later requires evidence that a valid notification was made.
