EY US has formed an alliance with Rillet (Gnau, Inc.), an AI‑native enterprise resource planning (ERP) and accounting software provider, to help modernise finance functions with integrated risk and control features.

The collaboration combines EY US’ capabilities in finance transformation, technology consulting, risk and controls, and operating‑model design with Rillet’s general‑ledger‑first, AI‑native finance platform.

The joint offering is aimed at organisations that have outgrown mid‑market ERP products and are looking to introduce more scalable and contemporary finance operating models.

EY US’ EY‑Rillet Alliance leader Michael Flynn said: “Finance leaders are navigating relentless pressure to improve speed, insight and control, while managing mounting complexity and risk.

“The EY-Rillet Alliance is differentiating precisely because risk management and controls aren’t a separate workstream: they are woven into the transformation from the start.

“That is how the Alliance will help clients build finance functions that are not just faster and smarter but genuinely resilient.”

According to the companies, the alliance will help businesses embed accounting rules and automation directly into core finance workflows.

These include activities such as posting journal entries, performing reconciliations, handling revenue recognition, managing the financial close and preparing reports.

Rillet co‑founder and CEO Nic Kopp said: “Finance transformation has long promised speed and insight, but integrating controls has remained a persistent challenge. With EY US, we are changing that.

“When AI is baked into the accounting logic from the ground up, controls don’t just keep pace – they become stronger, more continuous and more defensible under audit.”
