Are you leaving money on the table with every quote? Most plumbing and heating engineers are — and they don’t even realise it. This book shows you exactly how to price jobs with confidence, win more work, and finally get paid what you’re worth.

If any of these sound familiar, you’re not alone. Most plumbing and heating businesses struggle with pricing — not because they lack skill, but because nobody ever taught them how to quote properly.
The Quote Handbook changes that. Written by Aaron McLeish, specialist accountant and founder of Together We Count, this book draws on years of experience helping hundreds of trade businesses fix their pricing, protect their margins, and grow their turnover.
This isn’t theory — it’s a proven, step-by-step system built from real-world experience with plumbing and heating businesses just like yours.


Join hundreds of plumbing and heating business owners who have already transformed their quoting process and increased their profits using the strategies in this book.
The Quote Handbook is the first book in the Together We Build series. It covers everything from calculating your true costs and understanding your margins, to presenting quotes that win work and building a follow-up system that converts more enquiries into paying jobs.
Follow the step-by-step system in The Quote Handbook and you will:
