## What is Dundue?

You did the work. Dundue helps you get paid for it — politely.

Track the invoices you're waiting on, and Dundue tells you exactly when to follow up and writes the email for you: a six-step reminder ladder that escalates from a friendly heads-up (3 days before due) to a firm final notice (30 days past), every message professional, courteous, and ready to send from your own mail app.

• See what's outstanding and overdue at a glance
• A "reminders to send" queue so nothing slips
• Six polite templates, from courtesy note to final notice
• Sent reminders are logged — the ladder never repeats itself
• Clients with balances, payment tracking, write-offs
• Versioned JSON backup you control
• Light and dark mode

Private by design: everything stays on your phone. No account, no servers, no tracking — and every email goes out from your address, not ours.

Free for your first 15 invoices. One $9.99 purchase unlocks unlimited invoices, forever.

Pay once. Own it forever. No subscription. The Pro unlock is $9.99, one time.
