A few weeks ago, The Wall Street Journal explained how small companies are getting paid more slowly by their large company customers while those same large companies are forcing the little guys to pay faster. Well, Cortera’s data is showing that the little guys are getting paid more slowly by their small business customers, too.

Our Small Business Index (SBI) shows that while small businesses (companies with less than 500 employees – the SBA definition) are improving, but they’re paying 25% slower than a year ago and 20% slower than the overall business average. It is also important to note the widening gap between big companies and small companies. Pre-recession, the measures for the average, small and big companies tracked in a tight range, but since late 2008 we’ve seen a significant gap open up. Small businesses have a 55% higher DBT than large companies.

This is a dangerous situation for small businesses and a bad trend for the economy as a whole. When the payment flow between small businesses slows, the resulting friction impedes their ability to plan, grow and sometimes even survive.
