Dunn is invoicing software for freelancers and small businesses that does one job: getting you paid. Send an invoice with a card or bank pay button, and Dunn sends a friendly reminder before the due date, signed with your name. If the invoice goes late, Dunn adds the late fee you set, after emailing you a heads-up the day before so you can lower or waive it. Reminders pause the moment a client replies, and the reply comes to you. Every invoice keeps a timestamped history, and reports show which clients are always late. Payments go straight to your own Stripe account; Dunn never holds your money.
