Most enterprise invoices are never paid from an emailed invoice. Across the $2B+ in receivables Monk manages, 92% have to be submitted through the buyer accounts payable portal instead, and a failed submission is usually silent. Monk is an AI-native accounts receivable platform built around that problem. It files invoices into more than 600 corporate AP portals, including Coupa, Ariba and SAP Business Network, uploads 87% without a person, and brings each rejection back onto the invoice record with the reason attached. Collections runs on the same data. Julia, the Monk agent for Intelligent Collections, reads inbound replies and answers what the customer wrote instead of advancing a dunning schedule, clearing 90% of invoices without escalation. Outbound mail sends through your existing Gmail or Microsoft 365 mailbox. Payments match at 80%, rising to 95% once rules are added. Runs on QuickBooks, NetSuite or Dynamics 365 Business Central.
