What is an SQL?
A Sales Qualified Lead (SQL) is a prospect that has been thoroughly vetted and determined to be ready for active sales engagement. They've passed initial qualification and merit dedicated sales resources.
Unlike an MQL (marketing-qualified) which shows interest, an SQL has confirmed fit, need, and buying intent. They meet specific criteria that indicate a real opportunity to close.
SQL is a critical handoff point - it's when a lead moves from "potential" to "worth pursuing actively."
Why SQL Matters
The SQL stage is where the rubber meets the road for revenue generation:
Quality Control:
- Ensures sales spends time on real opportunities
- Filters out tire-kickers and bad fits
- Focuses expensive sales resources appropriately
- SQLs are the foundation of pipeline forecasting
- More predictable than broader lead metrics
- Indicates real revenue potential
- Shows which campaigns produce real opportunities
- Measures true lead quality, not just activity
- Aligns marketing spend with revenue
- Reps know which leads to prioritize
- Less time wasted on unqualified prospects
- Higher close rates on engaged opportunities
SQL Qualification Criteria
BANT Framework (Classic):
Budget:
- Can they afford your solution?
- Is budget allocated or available?
- What's their spending range?
- Are they the decision maker?
- Can they approve or influence purchase?
- Who else needs to be involved?
- Do they have the problem you solve?
- Is the need urgent or optional?
- What happens if they don't solve it?
- When are they looking to implement?
- Is there urgency or deadline?
- What's driving their timing?
- Technical fit (compatibility, requirements)
- Strategic alignment (company goals)
- Stakeholder landscape (who's involved)
- Competitive context (what else they're considering)
SQL vs MQL vs SAL
Understanding the lead journey:
MQL (Marketing Qualified Lead):
- Shows interest through behavior
- Fits demographic/firmographic criteria
- Marketing's assessment of potential
- Not yet vetted by sales
- Sales has reviewed and will pursue
- Initial handoff complete
- Not yet fully qualified
- Sales has actively qualified the opportunity
- Confirmed fit, need, timeline
- Ready for active selling and deal progression
Benchmarks
Lead to SQL Conversion:
- B2B overall: 15-25%
- Inbound leads: 20-30%
- Outbound leads: 10-20%
- Referral leads: 30-50%
- Average: 15-25%
- Top performers: 30-40%
- Enterprise: 10-20%
- SMB/Transactional: 25-40%
- Should happen within 1 week of handoff
- Best practice: Qualify in first or second call
- Dragged out qualification kills conversion
