The Black Book by Rachael Chadwick-Harrison — paperback front cover
Zero to
£1 million.Five years.
Her own business.

£1 million.

In annual recurring revenue.
Built from scratch in five years.

“I set my own firm from scratch and built it to one million in annual recurring revenue within five years.”
Rachael Chadwick-HarrisonFrom the opening chapter

She built the business.
Then wrote the book.

Rachael started Chadwick Accountants & Bookkeepers with nothing and grew it into a firm generating £1 million in annual recurring revenue within five years. The Black Book is the story of how she got there — and the practical lessons you can take into your own business.

It gets into the choices behind that growth: finding your place in the market, charging properly, winning clients, delivering well and building a team that can take the business further.

If you already have a service business and want to take it to seven figures, this book helps you work through what needs to happen next, one decision at a time.
