CPQ (Configure, Price, Quote) software automates the process of configuring complex products, calculating accurate pricing with rules and discounts, and generating professional quotes — reducing errors and accelerating quote-to-close. Core capabilities include product configuration with rules and dependencies, pricing engines with discount controls, quote document generation, proposal workflow and e-signature integration, guided selling recommendations, and integration with CRM, ERP, and billing systems. The category spans enterprise CPQ suites (Salesforce CPQ, Oracle CPQ, Conga CPQ) and mid-market tools (DealHub, PandaDoc CPQ) that combine quoting with proposal and e-signature.
