General Terms
Sales-Qualified Lead
A prospective customer that has been evaluated and deemed ready for direct sales outreach.
Definition
A Sales-Qualified Lead is a prospect that has been thoroughly vetted through both marketing qualification and additional screening criteria to determine high likelihood of becoming a customer. SQLs demonstrate specific buying signals, meet ideal customer profile criteria, and have shown sufficient engagement to warrant direct sales team involvement.
Examples
Lead requesting product demo after multiple content downloads
Prospect meeting budget and authority requirements
Contact showing high engagement across multiple channels
Lead explicitly expressing interest in purchasing
Frequently asked questions
Common questions about Sales-Qualified Lead, answered.
What is a sales-qualified lead (SQL)?
A sales-qualified lead is a prospect who has been vetted — by marketing and/or sales — as ready for direct sales engagement, based on their fit, interest, and intent. An SQL has moved beyond general interest to demonstrate enough buying readiness that a salesperson should actively pursue them. It's a key handoff stage in B2B and considered-purchase pipelines.
What's the difference between an MQL and an SQL?
A marketing-qualified lead (MQL) has shown enough engagement to be worth nurturing but isn't yet sales-ready — marketing keeps working them. A sales-qualified lead (SQL) has been further vetted as ready for direct sales contact and is handed to sales. MQL signals 'promising, keep nurturing'; SQL signals 'ready, sales should engage now'. The transition between them is the marketing-to-sales handoff.
How are leads qualified as SQLs?
Through criteria combining fit and readiness — does the lead match the ideal customer profile (industry, size, role, budget authority) and have they shown buying intent (requested a demo, engaged with bottom-funnel content, high lead score)? Many teams use frameworks (like BANT — budget, authority, need, timing) to qualify. The criteria should be agreed between marketing and sales so the handoff is consistent.
Why does the MQL/SQL distinction matter?
Because it aligns marketing and sales and focuses sales effort where it pays off. Sending sales every lead wastes their time on unready prospects; nurturing everyone forever never closes deals. Defining clear MQL and SQL stages — with agreed criteria — ensures sales engages only genuinely ready leads while marketing nurtures the rest, improving conversion and reducing friction between the teams.
Who decides when a lead becomes an SQL?
Ideally both teams, by mutual agreement. Marketing typically proposes leads as sales-ready based on scoring and qualification criteria, and sales accepts (or rejects) them against shared definitions, often formalized in a service-level agreement. This shared ownership prevents the common friction where marketing claims to send qualified leads and sales says they aren't ready — clear, agreed SQL criteria keep the handoff honest and effective.
