B2B accounts receivable teams lose significant cash to invoices that get stuck, not refused: a stalled internal approval, a rejected AP portal submission, a missing PO number, a departed AP contact, a short payment, or a promised payment that never arrives. The page states 43% of US B2B invoice value is overdue and 5% is written off as bad debt. Today this work is done by hand, with generic reminders on a schedule that don't address the actual cause of delay, leaving collections, dispute resolution, and cash application as manual, person-hours-heavy tasks.

Alder is described as an AI employee for accounts receivable that reads account history and email threads to find out why a specific invoice is late, then acts on the cause: finding the person who actually releases payment, submitting and fixing rejected entries in AP portals like Coupa and Ariba, locating missing PO numbers, finding new contacts when accounts go silent, pulling POs, receipts, and rates to support disputed or short-paid invoices, and remembering payment promises to follow up and check the bank feed. It also matches incoming bank payments to open invoices and flags mismatches. It integrates with existing tools (Gmail, Outlook, Teams, Slack, Coupa, NetSuite, SAP, QuickBooks, Stripe, Sequence, Brex, Mercury, Chase, Plaid) rather than requiring migration, starts read-only to observe workflows before acting, requires approval before anything reaches a customer, and logs every action for a full audit trail. The company states it can go live in 3 days, starting with one workflow such as collections or cash application before expanding.
