Sales Qualified Lead
A prospect that has been reviewed and confirmed by the sales team as meeting target criteria, ready for direct sales engagement.
A Sales Qualified Lead (SQL) is a prospective customer who has been assessed by the sales team (or an automated qualification process) and confirmed to meet the company's Ideal Customer Profile (ICP) criteria and to have expressed sufficient buying intent to warrant active sales pursuit. SQLs have passed the qualification bar set by the sales organization — they have the right budget, authority, need, and timeline (BANT) or similar qualification framework.
The SQL represents a key handoff point in the sales process: a prospect progresses from being an unqualified contact, to a Marketing Qualified Lead (MQL — showing engagement), to an SQL (confirmed by sales as worth pursuing), to an opportunity (active deal in the pipeline), to a customer (closed won).
SQL qualification frameworks include BANT (Budget, Authority, Need, Timeline), MEDDIC (Metrics, Economic Buyer, Decision Criteria, Decision Process, Identify Pain, Champion), SPICED (Situation, Pain, Impact, Critical Event, Decision), and GPCTBA/C&I (Goals, Plans, Challenges, Timeline, Budget, Authority, Consequences and Implications). Enterprise sales organizations use more rigorous frameworks; SMB-focused teams may use lighter qualification.
SQL-to-opportunity conversion rate and SQL-to-closed-won conversion rate are critical pipeline metrics. Low SQL-to-opportunity conversion may indicate poor MQL-to-SQL criteria alignment (marketing passing unqualified leads). Low SQL-to-won conversion indicates competitive issues, pricing problems, or qualification methodology gaps.
For PLG companies, the SQL concept may be supplemented or replaced by PQL (Product Qualified Lead) — accounts that have self-selected into product engagement, indicating higher conversion probability than traditionally qualified leads.
FAQs
What is the difference between an MQL and an SQL?
An MQL (Marketing Qualified Lead) has shown interest through marketing activities (content downloads, webinar attendance, email engagement) and meets demographic/firmographic criteria, but hasn't been sales-reviewed. An SQL has been evaluated by sales (or an SDR) and confirmed as having the budget, authority, need, and appropriate timeline. The MQL-to-SQL conversion rate measures how well marketing is qualifying before handoff to sales.
What is SLA between marketing and sales for lead handling?
A Service Level Agreement (SLA) defines how quickly sales must follow up with MQLs/SQLs — typically 'respond within 24 hours' or 'respond within 4 business hours for enterprise MQLs.' Research shows that lead response time dramatically impacts conversion: responding within 5 minutes vs. 30 minutes increases conversion probability by 100x. Marketing-sales SLAs, monitored via CRM reporting, ensure leads aren't wasted.
How do you prevent marketing from gaming MQL metrics?
Marketing gaming of MQL metrics (passing any contact as an MQL to hit quota) is a common dysfunction. Solutions: require SQL acceptance by sales as the metric marketing is measured on (not just MQL volume); implement a joint MQL definition reviewed quarterly; track MQL-to-opportunity and MQL-to-won rates, not just volumes; and have sales regularly give feedback on lead quality. Aligning incentives (marketing measured on revenue, not leads) is most effective.
