Invoice factoring is a somewhat unique way of financing because there may be day to day contact with the factoring company and your customers. Because there is so much involved during the accounts receivable financing process the factoring company becomes more familiar with their clients than standard lending where a computer tracks whether monthly payments are made. In many cases there is daily contact with the factor, or in other cases the factoring client is depending on weekly payroll funding.
So in that sense there is more to invoice factoring than the actual funding. The factoring company has to understand how a particular business operates in order to minimize any intrusion on the daily operations.
