FetchDue is an AI agent that gets your invoices paid. It watches everything you are owed, drafts every reminder in your voice, and escalates on your schedule from friendly nudge to firm text. It reads what clients write back: a promise to pay Friday gets logged against the invoice and followed up on if Friday passes. You approve every send until you flip on Autopilot. Connects to QuickBooks, Xero, HubSpot, Outlook, and Stripe.
