What LSL does
LSL CPAs is a privately held accounting and business advisory firm headquartered in Irvine, California, founded in 1929 and operating as a California limited liability partnership (LSL, LLP). The firm serves three core segments — closely-held businesses, government entities, and non-profit organizations — across ten industry verticals including automotive dealerships, construction, healthcare, manufacturing and distribution, professional services, real estate, entertainment venues, and family-owned enterprises. It employs 101-250 professionals across four offices in Irvine, Sacramento, Tempe (AZ), and The Woodlands (TX), and is a member of PrimeGlobal, a worldwide association of independent accounting firms.
Core services span Audit & Assurance, Tax Planning & Preparation, Business Advisory & Consulting, Outsourced Accounting, Fractional CFO Services, 401(k) Pension Plan Audits, Lease Accounting (ASC 842), Estate & Trust Planning, Wealth Advisory, and Government Finance Consulting. For government finance departments specifically, LSL delivers a Workiva-based automation stack covering ACFR preparation, budget book automation, XBRL tagging, and ADA Title II digital accessibility compliance; the capability is led by a Senior Implementation Manager recruited from Workiva itself. Differentiators cited in LSL's own material include specialized credentials (CCIFP for construction, CPFO, prior government finance leadership) and domain depth across government, construction, healthcare, automotive, and non-profit.
LSL's revenue model is professional services billing under custom engagement-based pricing, with fees set by project scope, complexity, industry specialization, and client size, typically structured as multi-year contracts. Go-to-market is relationship-driven, with industry specialization and thought-leadership content (blog, email newsletter, webinars, Twitter/X, OBBBA tax resources page) supporting inbound demand and direct proposal engagement. The firm has been named an Accounting Today Regional Leader for four consecutive years through 2026.
