Simplify's Take

What believers are saying

  • September 2026 RSM alliance opens middle-market distribution beyond venture-backed startups.
  • August 2026 Series C at $1 billion funds hiring, compliance, and enterprise sales.
  • Expensify’s September 1 integration makes Rillet stickier for expense-heavy finance teams.

What critics are saying

  • Oracle NetSuite, SAP, and Workday can copy features and squeeze Rillet’s pricing.
  • ERP replacements demand brutal migrations; one failed public-company rollout damages trust instantly.
  • If regulators restrict autonomous ledger actions, Rillet’s agentic pitch loses its core advantage.

What makes Rillet unique

  • Rillet’s real-time general ledger replaces NetSuite, SAP, and Oracle batch accounting.
  • Nicolas Kopp’s 2024 founding, 600-plus customers, and audit trails build credibility fast.
  • EY, RSM, Expensify, and Cin7 partnerships embed Rillet into finance workflows.

RSM and Rillet bring Agentic finance to mid-market.

RSM and Rillet bring Agentic finance to mid-market. Last updated: September 22, 2026 9:34 am Rillet, the Agentic ERP, and RSM US LLP, the leading provider of consulting, tax and assurance services for the middle market, announced a strategic alliance to help clients transform financial infrastructures for the AI era. Together, RSM and Rillet modernize fragmented finance systems to strengthen data and controls, streamline manual processes and prepare teams to use AI-native capabilities that automate routine accounting workflows, close faster and reduce the month-end scramble. Finance leaders face growing complexity across systems, processes, talent and compliance. Manual workarounds, siloed data and competing priorities limit visibility, slow decision-making and reduce the strategic impact of the finance function. This alliance brings together Rillet's Agentic ERP and RSM's experience helping finance leaders evaluate operating models, modernization strategies, AI readiness, governance and organizational change to drive process efficiencies and the transformation required to adopt AI responsibly and effectively. "RSM helps finance leaders align technology decisions to bring clarity to complex business challenges and build the operating model, data foundation, governance and adoption strategy needed to improve finance functions," said Daniel Beil, partner and cloud native capability leader at RSM. "Together with Rillet, we're enabling finance teams to build more intelligent operations with greater visibility, stronger controls and a foundation for responsible AI adoption." With a continuously updated general ledger, embedded AI agents, advanced revenue recognition, multi-entity accounting, and real-time reporting, Rillet helps finance teams move beyond manual workarounds and legacy close cycles to operate from a trusted, always-current view of the business. "RSM understands middle market enterprises, and this collaboration underscores a shared commitment to deliver AI-powered finance operations built for speed, scale and better visibility," said Nicolas Kopp, CEO and co-founder of Rillet. "By combining Rillet's Agentic finance infrastructure with RSM's deep finance transformation and implementation expertise, organizations can accelerate modernization, gain real-time visibility and build an Agentic finance function."

Payhawk transforms how finance teams work with new agentic Playbooks.

Payhawk transforms how finance teams work with new agentic Playbooks. The Fall '26 Edition further enhances Payhawk's AI Office of the CFO and introduces Playbooks: ready-made procedures that handle recurring finance tasks inside Claude and ChatGPT, reducing manual work for finance teams. Customers can also access all Payhawk data from their preferred AI platform using an MCP, and use the new Implementation Agent to go live in just a few hours. LONDON, Sept. 15, 2026 (GLOBE NEWSWIRE) - Payhawk, the AI-native spend management platform, today released its Fall '26 Edition, Prompt your finance, which enables finance teams to run their recurring work through Claude, ChatGPT or whichever AI assistant they already use. The edition also adds an Implementation Agent to Payhawk's AI Office of the CFO suite that configures Payhawk for new customers in hours, while continuing to enhance controls and processes for maximum efficiency and savings after go-live. Playbooks work inside the AI assistants finance teams already use, such as Claude or ChatGPT, and act on live Payhawk data through the Payhawk MCP, a secure connection that applies each user's permissions. The Playbooks are ready-made procedures that execute a finance job from start to finish. Each one covers a specific job for a specific role and knows what to check, what to ignore, and what a good result looks like. The library spans tasks such as closing the books, chasing receipts, controlling budgets, calculating cash on hand across entities, cleaning up suppliers, preparing for an audit, and getting ready for a supplier renewal. Teams can add their own. "The enhancements between Payhawk and Claude proved to be highly effective in our operational setup. It saves significant time, provides dynamic reporting, and simplifies data access. The AI-driven capabilities have become an important part of our day to day productivity," said Daniel Raffl, Cost Manager at TechnoAlpin. "Speaking to hundreds of CFOs this year, I realised that while enterprise software companies are racing to deliver MCP integrations focused on reading and reporting data, they are missing the real opportunity: building AI that acts, not just reads. Finance teams need more than another reporting layer. They expect AI to do real work for them by running end to end processes. That is why we took things to the extreme and built Payhawk to act and perform common tasks every finance team executes each month, saving them time and money," said Hristo Borisov, Co-founder & CEO of Payhawk. As part of this release, Payhawk is also introducing its new Implementation Agent, which helps finance teams implement the system in hours rather than days. The agent establishes a new benchmark for SaaS implementation by connecting customers' preferred ERP and HR systems, importing their data, and configuring workflows, policies, and processes to meet their specific needs. It also leverages insights shared with Payhawk's pre-sales team to understand each customer's objectives from day one. The Implementation Agent will support all major Payhawk integrations, including Oracle NetSuite, Microsoft Dynamics, Sage, Xero, DATEV, and QuickBooks, as well as recently announced integrations with SAP, Pennylane, Rillet, Campfire, and DualEntry. "The Implementation Agent acts as your private financial consultant, and early customers have gone live in under an hour. We're starting with onboarding and implementation, but the longer-term opportunity is continuous improvement. By learning from how customers use the system, the agent will optimise their setup over time and proactively recommend changes that make finance operations even more efficient," said Martin Reindl, General Manager & SVP Customer Success at Payhawk. The Fall '26 Edition is now live for Payhawk customers. Playbooks are available through the Payhawk MCP and in the Payhawk portal. Payhawk will demonstrate the edition in a live webinar on 29 September. Details and registration: https://payhawk.com/editions/fall-2026. About Payhawk Payhawk is an AI-native spend management platform that orchestrates global money across Bills, Cards, Expenses, Travel, and Procurement for maximum control, automation and savings. It provides a global money account on top of your ERP combined with agents enforcing rules, policies, and budgets on every payment while giving employees an effortless spending experience.

AI challenger Rillet takes on Oracle, SAP and Workday with real-time ERP agents

Rillet, a startup building AI-powered enterprise resource planning (ERP) software, is challenging legacy providers Oracle, SAP, and Workday. Co-founder Nicolas Kopp told CNBC that Rillet replaces monthly batch-processed financials with real-time accounting data powered by AI agents. The platform gives chief financial officers continuous visibility into revenue, cash, and margins, rather than periodic snapshots. Kopp said organisations can now see financials daily instead of every five to seven days. Investor Roelof Botha, who backed Rillet in May 2025, acknowledged the difficulty of switching ERP systems, comparing it to "open-heart surgery." He estimates competitors would need four to five years to catch up. The ERP market is worth hundreds of billions of dollars, but adoption of AI-native systems has lagged due to the complexity of replacing core financial infrastructure.
