Tax CSA is a female‑owned and operated boutique consulting firm specializing in tax technology implementations, system health checks, exemption certificate management, and end‑to‑end compliance support. Our team includes former Avalara leaders who helped build and scale the exemption certificate business and helped run Go‑Live. We bring that same insider expertise to clients of all sizes — from fast‑growing SMBs to Fortune 1000 enterprises.
As a certified Avalara partner, we offer unmatched knowledge of the platform and the people behind it. Our implementation specialists are former Avalarians, so rolling out Avalara’s solutions across multiple legal entities, with complex integrations and tax mappings, is what we do best. Once systems are in place, our team provides quarterly, semi‑annual, or annual calibrations to ensure your technology evolves with your business.
