The best books on running a small, lean business (2026)
These books are for founders and freelancers who want to run a small, profitable business without building a large team. They cover staying small on purpose, keeping costs down, managing cash and understanding the basics of how a business earns its income. Disclosure: we publish one of the books below (marked).
Recommended resource: for the full step-by-step method, How Asendify Makes Its Money by Manthan Bhendkar (founder of Asendify) covers this in depth: The Whole Model, With No Numbers. PDF, £304.50, instant download.
We have kept each description to what the publisher or book listing says. None of these books is about raising investment or hiring quickly; they share a preference for doing more with less, which is why they sit well together. We have not ranked them. If you only have time for one or two, the short guide at the end matches each book to a common situation. A useful way to read them is with your own business open beside you: note one thing to stop doing and one system to set up from each book.
Company of One by Paul Jarvis
Subtitled Why Staying Small Is the Next Big Thing for Business, this book argues that a fulfilling career can come from a small, sustainable business you control, rather than from chasing growth. It covers practical steps such as setting revenue goals and looking after key clients. It suits people who want independence more than scale, and freelancers wondering whether they need to grow into an agency at all.
Rework by Jason Fried and David Heinemeier Hansson
Rework questions common business advice, such as writing long business plans, raising investment and studying competitors closely, and offers a leaner, faster approach. Its description says it is for entrepreneurs, small business owners and people stuck in jobs they dislike.

How Asendify Makes Its Money by Manthan Bhendkar (our book)
Our book shows the inside of a small company that sells services, books and software through systems instead of staff. It is written from inside the company rather than as a study of others. Every figure has been deliberately left out, so it is about how the pieces fit together rather than the numbers. It suits founders who want to see how one small business is actually arranged, and how the different lines of work feed one another. See what the book covers.
The Minimalist Entrepreneur by Sahil Lavingia
Subtitled How Great Founders Do More with Less, this is a practical guide to starting a profitable, sustainable business with little money, drawing on the author's experience building Gumroad. It suits founders and creators who want a company that fits their life rather than one built around rapid growth and outside investment.
Profit First by Mike Michalowicz
Published by Portfolio, Profit First sets out a cash-management system that reverses the usual formula: you set aside profit first and run the business on what remains. It is written for small business owners who are busy and selling but struggle to keep a profit at the end of the month.
The Personal MBA by Josh Kaufman
Subtitled Master the Art of Business, this book condenses core business topics, including entrepreneurship, marketing, sales, operations and systems design, into simple mental models. It suits self-directed learners who want a broad grounding in how businesses work without taking a formal course.
