What is a Sales Qualified Lead (SQL)
An SQL is a contact who:
- has been qualified as an MQL (Marketing Qualified Lead),
- meets sales criteria (e.g. budget, decision-making authority, realistic timeframe),
- has confirmed interest in the solution (e.g. requested a demo, responded to a request for a quote),
- has been validated by a sales representative as ‘ready to talk’.
They usually transition from MQL to SQL following personal verification by a sales representative or based on an automatic trigger in the CRM, e.g. upon reaching a certain lead score or completing a specific activity (viewing pricing, filling in a questionnaire).
Why SQL is important for B2B companies
- It increases sales efficiency
Salespeople focus only on contacts with high conversion potential. - Shortens the sales cycle
SQLs are ready to make a decision, which shortens the time from first contact to contract signing. - More accurate forecasting
SQL metrics help to better predict closed deals, plan capacity and revenue. - Improves marketing–sales
collaboration A clear definition of the MQL → SQL transition reduces misunderstandings and strengthens mutual trust. - Increases campaign ROI
Campaigns are evaluated not only by MQLs, but by the number of SQLs and their conversion rate – a more realistic performance metric.
Practical use and examples
- CRM trigger: MQL → SQL
A lead reaches a score of 80, clicks on ‘Request a quote’ → the CRM automatically marks them as an SQL and creates a sales opportunity. - Telephone qualification by a sales representative
: An SDR contacts the lead, verifies BANT (Budget, Authority, Need, Timeline) → marks them as an SQL, schedules a meeting with an AE. - Manual SQL approval
For strategic accounts, the sales representative manually changes the status after analysing company information, e.g. following an ABM campaign. - Pipeline reporting
Marketing reports 120 MQLs, of which 48 converted to SQL (40%) → campaign optimisation focused on lead quality. - Transfer to the sales phase
After being changed to SQL, the lead is moved from the nurturing sequence to the direct sales process with a dedicated sales representative.
5 tips for working effectively with SQLs
- Define SQLs with the sales team
Have clear criteria: for example, role = decision maker, budget ≥ X, timeframe ≤ 3 months. - Introduce a qualification framework
E.g. BANT, CHAMP or MEDDIC – these will help distinguish ready leads from those that aren’t. - Track the conversion rate MQL → SQL → Opportunity
This helps optimise both the quality and timing of contact handover. - Automate transfer to CRM:
SQL = trigger for creating a sales case, assigning a task to a sales representative, or changing segmentation. - SQL ≠ closed deal – monitor quality retrospectively as well
. Track how many SQLs actually convert, and adjust MQL criteria retrospectively if necessary.
