How Checkout Champ sales tax works

What Checkout Champ does

Checkout Champ's built-in tax runs on tax profiles you set on each campaign: you enter a rate by country or zone, state, and optional postal code, and it applies from the shipping address, or the billing address for products that don't ship.

Where it stops

Checkout Champ describes this as a basic suite of tax features, not a full tax engine, and points merchants with complex tax needs to its tax service plugins. Every rate in a tax profile is one you enter and keep current.

What Kintsugi adds

Kintsugi is one of those tax service plugins. It determines the rate at checkout in real time on each campaign, and the same order data drives nexus tracking, registration, filing, and remittance.
