The 3PL Guide
About the guide

Published by Implentio, written for the brands who pay the bills

Working with a 3PL: The Complete Guide for Brands explains how 3PL pricing, contracts, operations and invoices actually work. It is published by Implentio, which audits 3PL and carrier invoices for ecommerce brands, and every article is reviewed by Implentio’s 3PL billing team: people who check 3PL invoices against contracts every day.

The guide is vendor-neutral. It never names a brand or a 3PL in its articles, and where it draws on Implentio’s own invoice reviews it reports only rounded shares of customers, never samples or benchmarks. It is free to read and share with attribution.

How this guide is written

  1. Answer first. Every article opens with a short, direct answer you can quote.
  2. Sourced line by line. Every number links to its source, and survey figures carry their year and sample.
  3. Vendor-neutral. We never name a brand or a 3PL, and we explain why 3PLs price the way they do.
  4. Show the math. Cost topics include a worked example with the arithmetic checked.
  5. Reviewed on a schedule. Carrier rules and published rates are re-checked every three months.
