A recent Wells Fargo survey conducted by the Gallup Organization shows confidence among U.S. small businesses is up. Revenues are stronger. Cash flow is better. Other positive signs reported in the survey include improved financial situations, higher capital spending, and more credit availability. Read the story here.The Wells Fargo survey is in line with the most recent NFIB Small Business Optimism Index, which we noted in our January 16 post here at Small Business Trends. All signs point to good times ahead for small business. We look for small business sales to increase over the next 12 months, which will have a ripple effect. Small businesses with increased revenues in turn will invest in goods and services and hire more staff.
