How we write definitionsEDITORIAL POLICY
Answer first
Every entry opens with a one-sentence definition you can quote as-is, then explains why it matters for an ecommerce brand.
US context
Rates, rules, and examples use US carriers, US Customs, and US retail practice unless stated.
Show the math
Metrics come with the formula and a worked example using clearly labeled sample numbers.
Vendor-neutral
No entry promotes a provider. Programs are named only to describe how they work.
