Alder

Alder is an AI employee for accounts receivable. It chases overdue invoices, resolves disputes and short payments with supporting documentation, submits and resubmits invoices to customer accounts payable portals such as Coupa and Ariba, and matches incoming payments to open invoices from the bank feed. The aim is to take the repetitive follow up and reconciliation work off the finance team while humans keep control of what customers see. It suits business to business companies whose receivables teams handle large volumes of unpaid invoices and portal driven payment workflows. Alder finds and writes to the actual decision maker at each customer account rather than a generic inbox, and it can start in a read only observation mode before taking any autonomous action. Every action is logged in an audit trail and is reversible. The vendor states that it does not train models on customer data and can deploy inside a private VPC where required. Integrations cover Gmail, Outlook, Microsoft Teams and Slack for communication, Coupa for portals, NetSuite, SAP and QuickBooks for accounting, and Stripe, Sequence, Brex, Mercury, Chase and Plaid for payments and banking.
