# Business process outsourcing (BPO)

Contracting a specialist provider to run a business process, such as collections or cash application, on your behalf.

Finance and accounting BPO providers run order-to-cash work for many clients, typically from delivery centers staffed by trained teams following each client's procedures.

Rex works with finance operations providers as partners, as the AI delivery system for their clients' work.
