Listed Sep 29, 2026

Alder is an AI accounts-receivable employee that reads the email thread on each overdue invoice, works out whether it's a missing PO, a rejected AP-portal submission, a short payment, or a contact who left, and follows through itself, looping you in only for anything a customer sees. It connects to Gmail, Outlook, Teams, Slack, Coupa, NetSuite, SAP, QuickBooks, Stripe and banking tools, and starts read-only so it observes your workflow before it acts. 43% of US B2B invoice value runs late and 5% gets written off — this targets that gap.

What holds up

  • +Starts read-only, observing your process before any agent writes or sends anything on your behalf
  • +Every action is logged, attributable and reversible — a real audit trail, not a black box
  • +Six named failure modes — missing PO, rejected portal, short pay, vanished contact — not just reminders

Mind the limits

  • −SOC2 compliance is still in progress, per the vendor — not yet certified
  • −No pricing shown on the page — you only find out cost after booking a demo
