SubjectPayment follow-up: INV-1042

Hi Jordan,

I’m following up because invoice INV-1042 remains outstanding. Could you confirm the payment date?

Thanks, Alex

Built for the awkward middle

Firm enough to matter. Human enough to send.

You do not need a collections platform for every late invoice. Sometimes you need the right words, the right facts, and a reminder to follow through.

01

Start with facts

Client, invoice, amount, and due date. KindlyDue avoids invented urgency, fake legal language, and guesses about fees.

02

Match the moment

Choose from five voices, six payment situations, three message lengths, and five clear requests—or let the timing choose a sensible starting tone.

03

Know what comes next

Export a simple follow-up calendar so a difficult client does not disappear behind another busy week.

Two minutes, then back to work

A small tool for a very real knot in your stomach.

KindlyDue gives you a draft, subject line, next action, and calendar-ready follow-up rhythm without turning invoice chasing into a second job.

Local-first by design

Sensitive business details do not belong in a mystery database.

The founding edition runs in your browser. Your draft is stored locally so you can come back to it, and it is not sent to a KindlyDue server.

Good questions

Before you put client details in a tool.

Does KindlyDue send the email for me?

No. It can open a prepared draft in your email app, but you remain the sender and should review every word first.

Are my invoice details uploaded?

Not in the founding edition. The drafting logic runs in your browser and stores the current draft in that browser’s local storage.

Does it calculate late fees or legal interest?

No. Those rights depend on contracts and local law. KindlyDue deliberately avoids guessing and focuses on factual administrative follow-up.

Is this a replacement for legal advice?

No. It is a writing and organization aid. Formal demands, disputed work, or large debts may deserve advice from a qualified professional in your jurisdiction.
