Hanlin Moss Yi

What Hanlin Moss Yi does

Hanlin Moss Yi P.S. is a privately held Certified Public Accounting firm headquartered in Seattle, Washington, with a second office in Xi'an, China. The firm delivers five integrated professional service lines — Taxes and Advisory, Business Valuations, Audit/Assurance, Accounting Services, and Consulting Services — to individuals and small to mid-size privately held businesses, with a specialized cross-border practice serving clients with operations or interests in the Chinese marketplace. Its core differentiators are bilingual English/Chinese delivery, PCAOB registration for public-company audit work, and deep involvement with the IACVA (International Association of Consultants, Valuators and Analysts), where managing partner William A. Hanlin, Jr. serves as President, partner Susan Yahong Yi serves as Vice President of Asian Affairs, and Of Counsel James P. Catty serves as Chairman of the Board.

The firm operates as a boutique partnership with 11-50 employees, billing primarily through professional-services engagements (hourly or fixed-fee) on multi-year client relationships. Revenue is generated from tax preparation and IRS representation, ASC 805/350-compliant business valuations for financing, M&A, and litigation, US GAAP/IFRS audits, financial statement preparation, and advisory work spanning capital structure, succession, and exit planning. Customer acquisition is driven by professional referrals, partner-level industry visibility through IACVA, and a bilingual website offering free initial consultations. Pricing is not publicly disclosed, consistent with engagement-based professional services.

Strategically, the firm is anchored by a stable senior partner team (Hanlin, Yi, Catty) with established credentials (CPA, CFE, ICVS, CFD) and over 25 years of operating history. The China office and IACVA global network spanning 50+ countries provide international reach disproportionate to the firm's small headcount. No funding rounds, acquisitions, technology platform, or AI/ML capabilities are evidenced in the input data; the firm's value proposition rests entirely on partner expertise, regulatory credentials, and the cross-border US-China niche rather than scalable technology or capital-intensive growth.
