Freelancers lose thousands every year not because clients can't pay, but because following up feels awkward. Most send one reminder and give up. Nudge fixes that. Add your client, add your invoice, pick a sequence. Nudge automatically sends escalating payment reminder emails until the invoice is paid. Tone escalates automatically. The moment your client pays, everything stops. You do the work. Nudge chases the Invoice. Free plan available. No credit card needed.
