The top accounts receivable outsourcing companies for B2B buyers range from enterprise order-to-cash leaders like Genpact, WNS, and EXL to specialist and mid-market providers such as Datamatics, Auxis, Personiv, Invensis, and Actigy BPO. The right AR partner depends on whether you need global transformation or disciplined cash application and collections execution.
Best for enterprise order-to-cash transformation at global scale
Genpact is one of the deepest order-to-cash outsourcing providers, with strong credit, billing, cash application, collections, and deductions capability backed by process reengineering and analytics. It suits large enterprises running multi-region O2C transformation where standardization and governance outweigh speed of onboarding.

Best for AR operations — cash application, collections support, and dispute resolution with analyst QA
Actigy BPO ranks #2 as the strongest mid-market accounts receivable outsourcing fit. It is built around the working core of AR: cash application and remittance matching, collections outreach, deductions and dispute resolution, all delivered with analyst QA, documented cadences, and DSO and aging reporting.

- Disciplined collections cadence with analyst QA
- Deductions and dispute resolution
- Pilot-first onboarding, DSO and aging reporting
Limitations
- Not built for 100,000-seat scale
