# Rex

Canonical: https://www.softwareadvice.ie/software/559783/Rex

> Rex is an AI service for accounts receivable (AR) and order-to-cash teams.

Rex is built for finance teams that are stretched: controllers, AR managers, and collections leads at B2B companies whose receivables volume has outgrown the team's capacity, and who don't want to solve that by adding another software platform they'd have to configure, monitor, and operate themselves.

With traditional AR software, your team still drives everything; the tool just makes each step faster. Rex works differently. Its AI agents take over the routine work directly: collections outreach and dunning sequences, invoice delivery, payment reminders and follow-up, and triage of the shared AR inbox, including replies to common customer requests like invoice copies and billing questions. The agents work every account on the ledger, every day, not just the largest ones.

Your team stays in charge of everything that matters. Rex is set up around your existing collections policies, payment terms, and tone of voice, and you decide the escalation rules: what the agents may send on their own and what needs sign-off first. Anything that calls for human judgment (a disputed invoice, an at-risk account, a request for a payment plan) lands with your team, with the full account history attached so you can act without digging. Rex helps your people work exceptions; it never replaces them.

Because Rex is a managed service, setup and ongoing tuning are done with you rather than left to you. The Rex team configures the service around your processes, monitors quality and performance over time, and adjusts as your policies change. There is no new platform for your team to learn or administer.

Rex fits into the systems you already use. It connects to ERP systems such as NetSuite, CRM systems such as Salesforce, and email and messaging tools such as Gmail and Slack, so invoice data, customer records, and communications stay consistent with your systems of record. Every action an agent takes is logged and reviewable.

If your AR team spends more time sending reminders and answering routine emails than making decisions, Rex is the difference between buying a better tool and getting the work done.
