The 5 leaks

Money leaks out between
the first email and the paid invoice.

  1. 1LeadsGood leads wait too long. Then they go with someone faster.
  2. 2ProposalsYour offer is late or has a mistake. They pick someone else.
  3. 3Projects“Just one small thing.” You end up working for free.
  4. 4ClientsA good client goes quiet. Then they leave.
  5. 5CashThe work is done. The money isn't in your bank.

What a leak looks like

A good lead. Lost in one weekend.

From Book 1. Harbor & Pine is a made-up studio the books use as an example.

  1. Friday, 4:52 pm

    A good lead writes in. Big project. They want to decide this month.

  2. Monday, 3:05 pm

    The owner finally replies. Two other firms answered on Friday.

  3. After the sales call

    The proposal goes out 9 days later. $31,000.

  4. Then

    Nothing. Nobody follows up.

  5. Months later

    “You were our favorite. But we never heard back.”

Nobody was lazy. Every step made sense. That's how a leak works: you never see it on an invoice.

Calculator

What do your leaks cost?

Type your own numbers. You get a rough answer right away.

The example numbers come from the studio in the books. Rough estimate. Not a promise.

One good lead is worth about $1,950 in profit to you.

The leads you answered late were worth about $17,600 in profit. A fast reply gives you a real chance at that money.

How the books use AI

AI writes the draft. You decide.

Nothing goes out until you've read it.

Spreadsheets do the math.

No prices from AI. Ever.

Remove names first.

Your clients' details stay private.

Is it for you?

Yes, if you…

  • run an agency, studio or consultancy with 2–20 people
  • run an IT, accounting, architecture, engineering or recruiting firm
  • sell projects or monthly work worth thousands
  • still do sales yourself, between client work

No, if you…

  • sell mainly to consumers
  • want AI to send emails for you
  • want a promise of guaranteed income

Questions

Do I need new software?

The included app runs in your browser, with no installation or account. Use the Excel files instead if you prefer. For AI-written drafts, use your own ChatGPT, Claude or Gemini account.

How do I keep my app data safe?

Save a backup file after each working session. Your entries stay in your browser; clearing browser data can remove them. Open your saved backup to restore them.

Which AI do I need?

Any common one, like ChatGPT, Claude or Gemini.

Do I have to read them in order?

No. Each book works on its own. Start with the leak that hurts most.

How much time does it take?

You can read a book in an evening. Most weeks in the 30-day plans take about 2–3 hours. The first week can take longer while you enter your existing records.

Is Harbor & Pine a real company?

No. It's a made-up studio. The example files let you follow and check the toolkit calculations used in the books.

Do I paste client emails into AI?

Only what's needed, with names and contact details removed. Many prompts work from short notes in your own words.

I'm not in the US. Does it work?

Yes. The books and the app show amounts in US dollars and dates in the US format; the numbers work the same in any currency. Only the legal notes (email, text messages, late fees) follow US rules.

What exactly do I get, and how?

Right after payment you get a download link, on the thank-you page and by email: the 5 books as PDF files, and the bonus AI Quick Wins Kit, which is the guided app and the 10 Excel files (5 empty templates and 5 filled-in examples).

Does the app work on Mac, Windows and iPad?

Yes on Mac and Windows: the app is one file that opens in Chrome, Edge, Firefox or Safari, with no installation or account. On an iPad or phone, read the books and use the Excel files; the app is made for a computer screen.

How do I get help?

Write to us: the Contact link is at the bottom of this page. We answer within one business day. For payment and invoice questions, use the support link in your order confirmation email.

“The leads were never the problem. They were already coming in. The question was only whether anyone would be there when they did.”
