Financial operations platform BILL announced a partnership Monday with AI-native ERP provider Rillet to streamline financial operations for growing businesses and accounting firms.

As part of this collaboration, the companies say they will launch a real-time, native two-way integration that continuously aligns accounts payable, spend, and financial data across both systems—providing accounting and finance teams with a real-time financial position and the clarity and confidence to make informed decisions as they scale.

“As growing businesses modernize, many are turning to AI-native finance platforms designed to operate in real time. Yet when critical tools aren’t continuously aligned, fragmented workflows and disconnected systems can still create silos, limit visibility, and delay reporting at close,” the companies said in a March 2 media release. “The new integration addresses this challenge through real-time, bi-directional data synchronization.”

With this integration, AP, spend, and expense data—including vendors, accounts, bills, credits, and all payment activity—are automatically synchronized across BILL and Rillet for supported workflows, thereby reducing errors and eliminating unnecessary manual steps. A real-time, two-way sync keeps financial records continuously aligned across both platforms, preventing duplication and preserving data integrity. Deep links allow teams to move seamlessly between systems, accelerating review and reconciliation.

“Growing businesses need finance systems that evolve with them, not limit them,” Mike Cieri, executive vice president of software at BILL, said in a statement. “As the trusted, intelligent finance platform connected through an 8-plus-million-member network, we approach integrations with the same philosophy we apply to innovation: purposeful, scalable, and built around how businesses organically operate. Our partnership with Rillet reflects that commitment by helping customers keep their finance systems connected and operate with greater agility as they adapt and scale.”

“BILL powers nearly half a million businesses and has become the backbone of intelligent financial operations,” added Nic Kopp, CEO and founder of Rillet. “When you combine that scale and expertise with Rillet’s perpetual ledger, you move from periodic accounting to continuous accounting. Our joint customers are achieving a faster close with books that remain up-to-date and audit-ready.”
