Rillet’s Agentic ERP, combined with RSM’s finance transformation expertise, helps organizations modernize financial operations, enhance real-time visibility, and accelerate the closing process.
SAN FRANCISCO & CHICAGO, September 21, 2026–(BUSINESS WIRE)–Rillet, the Agentic ERP, and RSM US LLP (“RSM”), a premier provider of consulting, tax, and assurance services for the middle market, have announced a strategic alliance designed to help clients transform their financial infrastructures for the AI era. By partnering together, RSM and Rillet aim to modernize fragmented finance systems, fortify data integrity and controls, streamline manual workflows, and equip teams with AI-native capabilities to automate routine accounting tasks, close books faster, and eliminate the month-end bottleneck.
Finance leaders increasingly face complexity across systems, processes, talent, and compliance. Manual workarounds, siloed data, and competing priorities restrict visibility, hinder decision-making, and diminish the strategic impact of the finance function. This alliance unites Rillet’s Agentic ERP with RSM’s extensive experience in helping finance leaders assess operating models, modernization strategies, AI readiness, governance, and organizational change—driving the process efficiencies and transformation necessary to adopt AI responsibly and effectively.
“RSM assists finance leaders in aligning technology decisions to bring clarity to complex business challenges, building the operating model, data foundation, governance, and adoption strategy required to elevate finance functions,” said Daniel Beil, partner and cloud native capability leader at RSM. “Together with Rillet, we are empowering finance teams to construct more intelligent operations characterized by greater visibility, stronger controls, and a solid foundation for responsible AI adoption.”
Through a continuously updated general ledger, embedded AI agents, advanced revenue recognition, multi-entity accounting, and real-time reporting, Rillet enables finance teams to transcend manual workarounds and legacy closing cycles, operating instead from a trusted, perpetually current view of the business.
“RSM possesses a deep understanding of middle market enterprises, and this collaboration highlights our shared dedication to delivering AI-powered finance operations built for speed, scale, and enhanced visibility,” said Nicolas Kopp, CEO and co-founder of Rillet. “By merging Rillet’s Agentic finance infrastructure with RSM’s profound finance transformation and implementation expertise, organizations can expedite modernization, achieve real-time visibility, and establish a robust Agentic finance function.”
