A potential customer who has been evaluated and deemed ready for direct sales engagement based on specific criteria set by the sales team. Unlike earlier stages in the lead qualification process, such as Marketing Qualified Leads (MQLs), an SQL has demonstrated a higher level of interest or engagement and meets the criteria that indicate they are likely to make a purchase decision. SQLs are typically identified through assessments of their needs, budget, authority, and readiness to buy. This qualification allows the sales team to focus their efforts on leads with a higher probability of conversion, improving the efficiency and effectiveness of the sales process.
