How accounts receivable automation works

Older AR tools automated the reminder schedule and gave a payment portal. The 2025 and 2026 generation uses AI agents that read the customer's replies, negotiate, escalate and match payments, and it has attracted more capital than any other corner of finance software: Stuut raised about $103 million, Monk $29 million, Fazeshift $22 million and Paraglide $5 million within eighteen months. Kolleno, Chaser and Upflow are the established mid-market tools; HighRadius and Billtrust serve enterprises.
