DueBuddy

What they say it does

You finish the work, send the invoice, and then silence. A week passes, then two. You don't want to nag, but you need to get paid. DueBuddy handles the awkward part. Upload the invoice, check the first email, approve it. From then on DueBuddy sends a short series of reminders from your own email address. The tone starts friendly and gets firmer over time. Stop it anytime with one tap, like when they finally pay.
