The agent runs on a schedule, not on rep goodwill. It reads new and changed records, fills the fields your scoring and routing depend on, flags conflicts instead of overwriting them, and queues anything ambiguous for a human decision. Enrichment stops being an annual cleanup project and becomes a background process.
The foundation work comes first. For a payments FinTech we stopped duplicates at the point of entry and imported more than 50,000 companies without making the existing mess worse. For another client we have kept CRM data current across every department for three years, with no in-house admin behind us.
