The 2026 buyer's guide to EDC software: Evaluating platforms by user satisfaction

When selecting an Electronic Data Capture (EDC) system, technical compliance and regulatory validation are baseline requirements. However, operational efficiency is largely dictated by user satisfaction. Systems that provide clear user interfaces, intuitive navigation, and responsive customer support reduce training time, minimize data entry errors, and accelerate query resolution across Clinical Research Coordinators (CRCs), Clinical Research Associates (CRAs), and Data Managers.

This guide evaluates six leading EDC platforms listed on G2, ordered primarily by their G2 satisfaction score. All G2 data points and satisfaction metrics cited in this report originate from the G2 Grid® Report for Electronic Data Capture (EDC) Software (Fall 2026) and public user profiles hosted on G2.com.
