Whether you’re evaluating platforms, onboarding your team, or working with developers on a SuiteCRM implementation, this glossary gives you clear, practical definitions grounded in real-world CRM context.
CRM Fundamentals
The building blocks of customer relationship management — the concepts every CRM user, admin, and decision-maker needs to understand.
CRM (Customer Relationship Management) — The strategy and software for managing all customer interactions in one platform.
Lead — An unqualified prospect who has shown interest but hasn’t been vetted by sales yet.

Logic Hooks — PHP functions in SuiteCRM that fire automatically on CRM events (before save, after save, on delete).
REST API — The standard interface for external applications to communicate with SuiteCRM programmatically.
Workflow — No-code automation rules in SuiteCRM that trigger actions when records meet specified conditions.
