Duefy is an AI invoice-collection tool for freelancers and small businesses. It chases every unpaid invoice for you: timed, escalating reminders over email and SMS, AI reply detection that catches "I'll pay Friday" and pauses the chase, dispute flagging, and a one-click pay page (Stripe). Import invoices from CSV, PDF, a photo, or email, or migrate in minutes from QuickBooks, Xero, FreshBooks, Wave, Zoho, Chaser, or InvoiceSherpa. Plans start at $19/mo with a 14-day free trial.
