California is home to more than 4.3 million small businesses, and over 12 percent of these are in the metropolitan San Francisco area. Small businesses accounted for 46.7 percent of employment in the San Francisco area, with the largest number of employees in the professional, scientific, and technical services industry (U.S. Small Business Administration 2025b, 2025c).
We analyzed 2.1 million small businesses with Chase Business Banking accounts operating during 2025, including more than 43,000 in the San Francisco metro area, to provide a snapshot of their financial health. The typical small business in San Francisco exhibits financial health measures—over 21 cash buffer days and $163,300 in annual revenues—that are more robust than those of a typical small business in the U.S. Median San Francisco revenues were higher than the overall sample in every industry, with professional services—the largest small business sector in San Francisco—having 39 percent higher revenues. While higher revenues may reflect the higher cost of living in San Francisco, cash buffer days scale balances by average outflows. This suggests that small businesses in San Francisco hold relatively larger cash reserves even after accounting for their higher outflows.
Cash buffer days: Small businesses may differ along many dimensions, such as size, industry, location, and growth trajectories, but they all need to manage their cash flows. Cash reserves can be used not only to absorb unexpected shortfalls in revenue or increases in expenses but also to invest in growth opportunities. We use cash buffer days to measure how long a small business could maintain its average outflows in the event of a complete disruption to inflows.
