About this app

Waiting on an invoice is bad enough. Writing the awkward "just checking in" email is worse. Dundue does both parts for you.

Track the invoices you're owed, and Dundue tells you exactly when to nudge — then writes the polite email so you just tap send.

THE SIX-STEP LADDER
A proven follow-up sequence that escalates gently:
1. Courtesy heads-up — 3 days before the due date
2. Due-today note
3. Friendly check-in — a few days past
4. Firmer reminder — two weeks past
5. Direct request — three weeks past
6. Final notice — 30 days past

Each step is pre-written, professional, and one tap from your mail app or share sheet. Sent reminders are logged, so the ladder never repeats a step and never fires one it blew past.

YOU STAY IN CONTROL
Dundue never contacts your clients. Every email goes out from your own address, sent by you, when you decide. Dundue just makes sure you never forget and never have to find the words.

SEE WHO OWES YOU AT A GLANCE
• Invoices color-coded by urgency: overdue, due soon, upcoming, paid
• Per-client history — who pays on time, who always needs a nudge
• Log payments as they land

PRIVATE BY DESIGN
Everything lives on your phone. No account, no cloud, no analytics. Your client list and amounts are nobody's business but yours.

Built for freelancers, contractors, and small agencies — anyone who does the work, sends the invoice, and then has to be their own accounts-receivable department.

Stop dreading the follow-up. Dundue remembers, Dundue writes, you get paid.
