Tax Setup & Rules

Define What You Sell Design & Setup High-signal capability Updated July 2026

Tax Setup & Rules — Tax setup and rules determine how each product is taxed — codes, nexus, exemptions, and jurisdiction logic — before a single invoice exists. Address and tax ID validation feed it clean inputs; invoicing and checkout apply its determinations at transaction time.

Where it sits in the lifecycle

Tax Setup & Rules lives in the Design & Setup phase of Define What You Sell — the stage where you design the catalog, pricing, and rules of the offer. In the corpus tool index this phase maps to the CPQ and Billingcategories.
