The recent issue of The Green Sheet has an article about the merchant cash advance industry, Sizing Up Merchant Cash Advance.
This article was written by First Annapolis Consulting, a consulting firm that specializes in consulting and investment bank services for the payments industry. Most of their assumptions were previously indicated in this blog including the size of the industry (First Annapolis' best educated guess is $500 million to $700 million in future receivables purchased). I believe it's closer to $1 billion at this point (as mentioned in my October 2007 posting).
They also indicate how there will be some shakeup in the merchant cash advance industry as I predicted in my 2008 Merchant Cash Advance Industry Predictions.
