Expensify Unveils Native Integration with AI-Native ERP Rillet for Real-Time Expense Sync

Expensify and Rillet have launched a native integration to automate expense management and general ledger reconciliation for high-growth firms. By enabling a two-way sync between Expensify’s spend management platform and Rillet’s AI-native ERP, finance teams can achieve a continuous close, reducing the manual burden of coding transactions and managing out-of-pocket reimbursements.

What was announced

The partnership introduces a direct connection between Expensify and Rillet, designed to eliminate manual data entry and CSV uploads. The integration facilitates an automatic, two-way synchronization where Rillet’s categories, dimensions, and tax rates are pulled into Expensify. This ensures that every expense is accurately coded at the point of spend, maintaining consistency across both platforms without the need for manual intervention from accounting teams.

Functionally, the integration handles several key accounting workflows. Out-of-pocket expenses recorded in Expensify are automatically posted back to Rillet as vendor bills, while company card transactions are recorded as credit card charges against the appropriate accounts. Furthermore, reimbursements and card transactions remain in sync automatically, allowing for real-time reconciliation. This setup is intended to prevent miscoded expenses and eliminate the need for finance departments to chase employees for corrections.

The system is aimed at businesses of all sizes, including hyper-growth startups, public companies, and mid-market enterprises that require a more agile approach to financial reporting. By syncing these data points, the integration supports a "continuous close" architecture, where the general ledger reflects the current state of the business throughout the month rather than just at the end of a reporting period. The integration is available immediately for businesses running Rillet.

"The future of finance is real-time. With Rillet, when something happens in the business, the books already reflect it. This integration brings expenses into that loop: an employee swipes a card and the transaction arrives in the general ledger coded and reconciled, which is what makes a continuous close possible. The books stay current all month,"

Nadiv Rahman, Head of Partnerships at Rillet.

The companies involved

Expensify, Inc. (Nasdaq: EXFY) is a major player in the spend management space, providing a platform for expenses, corporate cards, and travel. The company reports a user base of 15 million members globally and has established itself as a top-rated application on platforms such as G2, TrustRadius, and Capterra. Expensify has recently focused on expanding its card offerings and spend control features to cater to a broader international market, moving beyond simple expense reporting into a comprehensive financial management tool for businesses.

Rillet is an AI-native Enterprise Resource Planning (ERP) platform designed for what it terms "agentic finance." The platform integrates a real-time general ledger with a continuous close architecture and AI agents, allowing finance teams to manage books with enhanced context and auditability. Rillet serves a diverse clientele ranging from hyper-growth startups to public companies and mid-market enterprises, and it maintains active partnerships with leading accounting firms. The company positions itself as a modern alternative to legacy ERP systems, focusing on automation and real-time data accuracy to streamline the finance function.

What this means

This integration signals a shift away from the traditional "batch" processing of expenses toward a continuous, real-time accounting model. For the fintech sector, it highlights the increasing pressure on legacy ERP providers to match the agility of AI-native platforms that offer deep, native integrations rather than superficial data exports. By bridging the gap between spend management and the general ledger, Expensify and Rillet are addressing a primary pain point for mid-market finance teams: the "month-end crunch." As AI agents become more prevalent in back-office operations, the demand for clean, real-time data feeds will likely force more established players to rethink their integration strategies to remain competitive.
