Analysts report that both the cash advance and the invoice factoring sectors are increasing in prevalence and popularity, with business growing in both sectors at double digit levels each year. The Green Sheet estimates the market for merchant cash advances is currently $500-$700 million, with the potential to reach $3-5 billion within the next several years. The market for “factoring” (B2B loans against outstanding invoices) is even larger: Morgan Stanley estimates that factoring produces $13-15 billion per year.
