# The First 90 Days vs Traction / EOS

Which book does a new owner actually need first?

## Choose The First 90 Days

Read The First 90 Days in the window it is named for, between wiring the money and feeling like the owner: diagnose what you have inherited, find early wins, and build credibility before you change anything. It was written for executives joining big companies, so it carries no seller handoff, no personal guarantee and no cash controls, and you will translate its frameworks down to a fifteen-person business yourself.

## Choose Traction / EOS

Read Traction a few months later, once you know the business well enough to know what to measure: scorecards, a weekly meeting, quarterly priorities and a clear accountability chart, which is a rhythm hundreds of thousands of small companies run on. Two cautions from its own record. It is dogmatic by design and works best swallowed whole, which is heavy for eight people, and installing it in month one competes with the learning that should be filling month one.

## Side by side

| | The First 90 Days | Traction / EOS |
| --- | --- | --- |
| What It Is | A playbook for leadership transitions, diagnosing the situation you're inheriting, securing early wins, and building credibility fast. Written for executives entering new roles, it maps remarkably well onto taking over a just-purchased business. | The book behind the Entrepreneurial Operating System (EOS), a simple operating cadence (scorecards, weekly L10 meetings, quarterly rocks, accountability charts) that hundreds of thousands of small companies run on, and a common choice for new owners installing structure post-acquisition. |
| Category | Operating Resources | Operating Resources |
| Pricing Model | One-Time | One-Time |
| What It Costs | The updated and expanded edition, published May 2013, is $30.00 in hardcover from the publisher's own store. No workbook, assessment or digital toolkit is sold beside it. | Book, paperback typically around $20 retail (Simon & Schuster / BenBella; varies by retailer), with a free chapter download and 50% off bulk orders of twenty or more. The software half now publishes a flat price: the first user is free forever and every additional user is $10 a month, with no contracts, no minimums and no feature tiers. Certified implementer fees are still unpublished and are the significant cost. |
| Best For | The 90 days between wiring the money and feeling like the actual owner | Owners a few months post-close who've learned the business and are ready to install an operating rhythm |
| Where It Fits | Operate & Grow the Business | Operate & Grow the Business |
| Our Verdict | Read it during diligence so the transition plan exists before day one. | The default post-close operating system; install it in month 4, not week 1. |
