CSI Accounting & Payroll

CSI serves small and medium-sized businesses that aren't large enough to warrant having internal accounting or payroll departments. We specialize in small business accounting, bookkeeping, consulting, taxes, and payroll. We serve clients across the continental U.S., and our long Columbia (Baltimore/DC) history means we're on top of local ordinances. We are part of several professional organizations, including the Professional Association of Small Business Accountants (PASBA), which has twice recognized CSI Accounting & Payroll as one of the top small business accounting firms in the U.S. They awarded CSI with the 2013 Large Firm of the Year Award, and in 2018, they awarded owner Brian Paulson with the Lifetime Achievement Award.
