What is notice of assignment (noa)?
Notice of Assignment (NOA): The letter that tells your customer to pay the factor directly.
How it works
When you factor an invoice, your customer receives a Notice of Assignment redirecting payment to a lockbox controlled by the factor. This is standard in B2B and does not signal financial trouble—most large buyers process dozens of NOAs a month.
