Sales Qualified Lead (SQL)
A lead that has been evaluated by the sales team and confirmed to have genuine purchase potential based on budget, authority, need, and timeline. SQLs have progressed beyond marketing qualification through direct sales interaction.
SQLs represent leads where a sales representative has had a meaningful conversation and confirmed the lead has real buying potential. The qualification typically follows frameworks like BANT (Budget, Authority, Need, Timeline) or MEDDIC (Metrics, Economic Buyer, Decision Criteria, Decision Process, Identify Pain, Champion). This sales validation step filters out leads that appeared qualified based on marketing signals but lack genuine purchase readiness.
For growth operations, the MQL-to-SQL conversion rate is a critical health metric. It measures the alignment between marketing's definition of a qualified lead and sales' reality. A healthy MQL-to-SQL rate typically ranges from 30-50%. Below that, marketing is passing low-quality leads that waste sales time. Above that, marketing may be under-qualifying and missing opportunities. Track SQL conversion rates by source to identify which marketing channels generate the highest quality leads. Use SQL feedback to refine lead scoring models and improve targeting. The SQL stage is also where you can measure true marketing ROI by connecting marketing spend to pipeline that sales has validated as real opportunity.
