What Is an SQL?
Also known as sales qualified lead, SQLs
An SQL (sales qualified lead) is a lead that the sales team has reviewed, usually through a call or discovery conversation, and confirmed is worth actively pursuing. It matches the ideal customer profile and shows a real need, a reachable decision-maker and a plausible timeline. SQLs typically become opportunities in the sales pipeline.
Sales Qualified Lead (SQL) explained
SQL status is earned through qualification, not activity. An SDR or account executive checks the lead against criteria such as BANT or MEDDIC: is there a problem we solve, a budget or path to budget, someone with authority involved, and a reason to act within a reasonable time? If yes, the lead becomes an SQL. If not, it goes back to nurture or is disqualified.
In outbound, many leads skip the MQL stage. A prospect who replies to a cold email and agrees to a meeting goes straight to a discovery call, and becomes an SQL if that call confirms fit. That is why outbound teams often report on meetings held and SQLs rather than MQLs.
Tracking SQLs connects lead generation to revenue. The ratio of SQLs to closed deals tells you whether qualification is too loose. The SQL count by source tells you which channels create real pipeline, not just activity. It also keeps marketing and sales honest with each other, since both can see how many leads survive a real conversation.
Sales Qualified Lead (SQL) example
An SDR books a discovery call with the head of IT at a 400-person manufacturer who replied to a cold email. On the call, he confirms the company's current backup vendor contract ends in four months, the CFO has already approved budget to switch, and he leads the evaluation. The SDR marks him as an SQL and hands the deal to an account executive.
How to qualify an SQL
Agree written criteria
Define what sales must confirm, such as pain, authority, budget path and timing, so every rep qualifies leads the same way.
Prepare before the call
Review the account, role and any engagement history so the conversation focuses on their situation, not basic fact-finding.
Ask open discovery questions
Explore the problem, its cost, who else is involved and what would trigger a decision. Listen more than you pitch.
Record and route
Log what was confirmed in the CRM, convert qualified leads to opportunities, and send others back to nurture with a reason.
Common mistakes
- Marking every booked meeting as an SQL before any qualification has actually happened.
- Using a checklist rigidly and disqualifying good buyers who simply have not set a budget yet.
- Not recording why leads were disqualified, which removes the feedback marketing needs to improve targeting.
- Letting definitions drift between reps, so SQL counts cannot be compared across the team.
Sales Qualified Lead (SQL) FAQ
An MQL is flagged by marketing based on fit and engagement data. An SQL has been vetted by sales, usually in a conversation, and confirmed to have real need, authority and timing. MQLs indicate interest; SQLs indicate a likely sales opportunity.
Sales decides, typically an SDR, BDR or account executive after a qualification call. The criteria should be agreed with marketing in advance and written down, so the decision is consistent and both teams trust the numbers.
An SQL usually becomes an opportunity in the CRM, with a deal value and expected close date. From there it moves through pipeline stages such as demo, proposal and negotiation until it is closed won or closed lost.
Not always. Some companies convert SQLs to opportunities immediately, so the terms mean the same thing. Others require an extra step, such as a completed demo or a confirmed budget, before an SQL becomes a forecastable opportunity.
