Dundue: Invoice Reminders

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.
