Vertex announced a broadened partnership with CPA.com that launches an AI‑driven sales‑tax compliance solution built in collaboration with Kintsugi. The new offering equips accounting firms of all sizes to automate exposure analysis, registration, filing, and ongoing compliance for their clients, leveraging Vertex’s tax engine and Kintsugi’s AI categorization technology.
The launch is part of Vertex’s broader AI strategy, following the October 2025 introduction of a Kintsugi‑powered solution for SMBs. Vertex invested in Kintsugi in April 2025, and the partnership combines Vertex’s tax‑engine expertise with Kintsugi’s machine‑learning classification to deliver faster, more accurate compliance workflows.
Bradd Wildstein, Vertex’s Vice President of Partner Sales, said the expansion will help CPA firms unlock new revenue streams and simplify return filing. Michael Cerami, Executive Vice President at CPA.com, noted that the solution is right‑sized for mid‑market and SMB clients, enabling them to access enterprise‑level compliance without the complexity of larger platforms.
Vertex’s recent Q3 2025 earnings beat expectations, underscoring strong execution amid a challenging environment. The company remains focused on scaling its AI platform and expanding into mid‑market segments, positioning the new partnership to drive growth beyond large enterprise customers.
The partnership offers firms a choice between a white‑label platform and a hands‑free automation option, both supported by dedicated help and seamless integration with leading ERP, billing, and e‑commerce systems. The result is fast setup, transparent workflows, and integrated reporting that can accelerate adoption and revenue generation for CPA firms.
