Rex for enterprise
AI agents run order-to-cash across your existing systems, entities and regions. Built to operate at enterprise scale, under your procedures, policies and controls.

Scale
Enterprise operations span several ERPs, shared inboxes, and the portals each buyer requires. Rex works across all of it, on the systems you already run, and most teams go live in under four weeks.
Human approvals are captured alongside agent actions, giving your team a complete record of how work was executed.

Rex works alongside your existing finance infrastructure, connecting ERPs, customer systems, banks and portals to execute work across your order-to-cash operation. Your systems of record stay in place.
Nothing is migrated or replaced. Your ERPs, CRM, bank feeds and portals keep their data and their role.
Several ERPs, regional instances and acquired systems often run side by side. Rex works across all of them at once.
A single case can start in a bank feed, continue in the inbox and close in the ERP. Agents carry it through end to end.

Synthesia deployed Rex in under three weeks. Today, Rex manages order-to-cash cases across its inbox, NetSuite, Salesforce and customer portals, from intake through resolution or escalation.
“Rex has gotten smarter over time, and looking back from April and May to now, the improvement has been significant. It’s figured out that this is how we communicate with our customers.”

Yes. Rex works across SAP, Oracle NetSuite, Microsoft Dynamics, Workday and Oracle Fusion, including several at once. Procedures, approval thresholds and permissions are set per entity, so each subsidiary keeps its currency, tax and local requirements while sharing one operating model and one audit trail.
No. There is no data migration, and your ERP stays the system of record. Rex connects to the systems you already run and records its work there, alongside your CRM, inboxes, bank feeds and customer portals.
You decide which actions each agent and person can take, by role and entity. Sensitive actions, such as sending a customer email or applying a credit, can wait for approval before they run. Every action by agents and operators carries a decision trace: who or what acted, the rule applied and the outcome.
The agent stops and escalates with the context needed to decide. Missing POs, rejected invoices, MFA checkpoints, expired credentials and unclear instructions route to the right person under your procedures, whether that is your team or a Rex finance expert.
Rex takes on the routine work and hands exceptions, approvals and customer decisions to the people who own them today, in an in-house shared services centre or an outsourced team. Each group gets role-based access and works from the same audit trail.
Yes. Rex has completed a SOC 2 Type II audit and is GDPR compliant, with EU data residency. Data is encrypted with AES-256 at rest and TLS 1.2 or higher in transit. Each customer runs in an isolated environment, and enterprise SSO runs through WorkOS, with SCIM directory sync and MFA. The SOC 2 report and subprocessors are in the Trust Center at https://trust.rex.inc.
