AutoDunn is an invoicing software product available on the Whop marketplace, created by sun8b and launched in August 2026.

Stop chasing money you're owed. AutoDunn automatically tracks every dollar clients owe you — invoiced or just promised over a call — and reminds them before you have to. Built for freelancers and small studios (designers, devs, consultants, lawyers, accountants) who bill by project or by hour and are tired of Excel sheets, awkward follow-up texts, and forgetting who still owes what. WHAT IT DOES • Tracks both formal invoices AND verbal/handshake commitments • Manual entry or bulk CSV import — log deposits, mark payments received • Dashboard: total receivables, overdue amount, deposits, client concentration, sorted by days overdue • Automated email reminders: pre-due confirmation (Level 0) + 3-tier overdue escalation (Level 1/2/3) • Early-payment discounts (2%/10 Net 30) and late fee calculations • Smart de-duplication — never spams the same client twice at the same level for the same invoice PRICING $15/month · 14-day free trial · after the trial, view-only access is kept but automated reminders pause until you subscribe. If you've ever lost a client relationship over an awkward "hey, did you forget to pay me?" text — AutoDunn sends it for you, professionally, on autopilot.

AutoDunn has is priced at $15/month.
