SQL (Sales Qualified Lead)

A Sales Qualified Lead (SQL) is a lead that sales has accepted as worth their time — having met the criteria for active sales engagement — typically after passing through the MQL stage and through SDR qualification.

What is SQL (Sales Qualified Lead)?

SQL is the stage where a lead becomes sales' responsibility. The criteria are stricter than MQL: an SQL has both fit and demonstrated interest sufficient that an AE will spend real time. The transition from MQL to SQL is often handled by SDRs — they qualify the MQLs marketing produces and pass through only those that warrant AE attention. Strong SQL definitions include explicit qualification criteria (often BANT-style: Budget, Authority, Need, Timeline) and a documented SLA on AE engagement time.

Why it matters

  • Sales' acceptance gate — sales decides who's worth their time.
  • MQL-to-SQL conversion rate is a key sales-marketing alignment metric.
  • Clear SQL criteria reduces the most common sales-marketing dispute.

Use cases

  • AE engagement gate. AEs work only SQLs, not raw MQLs or inbound leads.
  • Funnel-conversion reporting. MQL-to-SQL conversion as the primary sales-acceptance metric.
  • Quality feedback loop. SQLs that close vs SQLs that stall feed back into qualification criteria.
