14 days past due

Hi [NAME],

Invoice #[NUMBER] for [AMOUNT] was due on [DATE] and is now 14 days

If something has changed on your end — budget frozen, approval stuck,
invoice never reached accounts — tell me and we'll work out a plan.
I'd rather know than keep sending these.

If it's already been paid, forward me the remittance and I'll close
it off.

Hard Emails, Handled

The 12 client conversations that cost you money — written, ready, and sounding like you.

You've been not-writing the same email for eleven days.

You know the one. The invoice that was due on the 3rd. Or the client who's added four "quick favors" to a fixed-price project. Or the rate increase you've needed to send since spring. You open the tab. You write "Hi —". You close the tab.

A solo operator sitting on one $2,400 invoice for three extra weeks isn't losing three weeks. They're losing the invoice after that one too, because the same silence repeats. You're not bad at business. You're bad at one specific email — and so is everyone else doing this alone.

What this is

A 32-page kit of the twelve client emails that are hard to write, written out in full, with the AI prompts that rewrite each one in your voice. You copy it into your own workspace and it's yours.

And eight phrases that are costing you money

Page 19 is a list of the things people write instead of the email, and what each one actually communicates. The first four:

  • "Just checking in" — announces the email contains nothing.
  • "No rush!" — written permission to ignore you.
  • "Sorry to bother you" — frames your paid work as an imposition.
  • "Let me know your thoughts" — an invitation to do nothing.

None of the replacements are more aggressive. They're more specific. That's the whole trick.

Read three pages before you decide

Not a blurred screenshot and not a table of contents. Three complete pages out of the thirty-two, in full, exactly as they appear in the document.

The one rule

Every email in here obeys a single rule, and if you only take one thing from this document, take this:

Give them one specific thing to do, and one dignified way out.

That's it. That is the difference between an email that gets answered and an email that gets archived.

One specific thing to do. Not "let me know your thoughts". Not "when you get a chance". A dated, concrete action: pay this link by Friday, reply with a number, tell me which of these two you want. Vague asks feel polite. What they actually do is transfer the work of deciding what you want onto a person who has forty other emails, and that person will choose the one that requires no decision.

One dignified way out. People don't ignore you because they're hostile. They ignore you because replying means admitting something awkward — the budget's frozen, they forgot, they went with someone cheaper, they can't afford you any more. Silence is the cheapest way to avoid saying that out loud.

So say it for them. "If the budget's frozen, tell me and we'll work out a plan." "It's more than you wanted to spend — that's fine and it doesn't offend me." The moment the awkward thing is on the page in your handwriting, it stops being awkward, and you get a reply.

Every template here is that rule twice: an ask with a date on it, and an exit with no shame in it.

What this means for the tone question

You are probably worried about sounding aggressive. Look at what actually makes these emails land — none of it is force. It's specificity and an exit. You can be extremely warm and still be completely clear. What you cannot be is vague and expect an answer.

The word to delete, everywhere, forever, is "just". Every instance of it in an email is you apologising for having sent the email. Find it, delete it, send.

Late invoice — the firm follow-up (day 14)

When to use it. Invoice is 14 days past due. You've sent one friendly nudge. Silence.

The email

Subject: Invoice #[NUMBER] — payment status

Hi [NAME],

Invoice #[NUMBER] for [AMOUNT] was due on [DATE] and is now 14 days
past due.

I need it settled by [DEADLINE]. Link: [LINK]

If something has changed on your end — budget frozen, approval stuck,
invoice never reached accounts — tell me and we'll work out a plan.
I'd rather know than keep sending these.

If it's already been paid, forward me the remittance and I'll close
it off.

[YOU]

Why it works. No apology, so nothing signals that asking to be paid is an imposition. One specific deadline, so there is a thing to be late for rather than a mood to manage. And an open door that makes it easy for them to tell you the real reason — because the real reason is nearly always a frozen budget or a stuck approval, and neither gets solved by another nudge.

What most people send instead. "Just circling back — no rush, whenever you get a chance!" This fails because it gives them permission to keep ignoring you.

A subject line has one job: make the email look like a specific piece of admin rather than a feeling. Numbers, dates and nouns get opened. Verbs about your emotional state do not.

Who this is for

Freelancers, consultants and agencies of one — people who do the workand send the invoices, with nobody else to hand the awkward email to. If you've ever opened a draft, written "Hi —", and closed the tab, this was written for you specifically.
