findings, if we build it:

Works with what you send now

Forward an emailed invoice or PDF and you're set. No switching to FreshBooks or QuickBooks just to get reminders; Duebird watches the due date and follows up the day it slips.

Escalates like you would

A friendly nudge at day 3. A firmer note at day 10. A final notice at day 21. You approve the tone once and never write another reminder.

You stay the good guy

Reminders come from Duebird, not from you. The client relationship stays warm and the invoice still gets paid.

Full disclosure: Duebird doesn't exist yet. This page measures whether it should. Sign up and you're voting yes. If we build it, you get it first and cheapest; if we don't, we'll tell you what happened. © 2026 Astero Software
