Performance is a big issue with invoice factoring. A factoring company needs to know that whatever their client does, they’ve truly done it. In order to use accounts receivable financing, the work must be completed and accepted by the customer. An invoice isn’t technically an invoice until the job is finished. So leaving aside all prior arrangements of customers allowing an invoice to be submitted beforehand, no advances unless the worked has been performed to the customer’s satisfaction. And that’s performance in the invoice factoring world.
