What Is a Sales Qualified Lead (SQL)?
A sales qualified lead (SQL) is a lead that sales has accepted as a genuine opportunity worth pursuing — vetted for fit, interest, and timing. It is the stage after a marketing qualified lead.
Why the SQL stage matters
The SQL handoff is where marketing effort becomes sales pipeline. Getting the definition right keeps closers focused on real opportunities, not noise.
A shared, written SQL definition prevents the endless 'these leads are bad' debate between teams.
MQL vs SQL
An MQL has shown enough interest for marketing to flag it; an SQL has been accepted by sales as worth working. The bar is higher and the timing is closer.
How to qualify an SQL
Confirm fit (right company and role), interest (a real signal), and timing (a reason to act now). If all three hold, it is sales-ready.
In practice
The handoff from MQL to SQL should involve a rep actually validating fit and intent directly with the prospect — not just an automated score crossing a threshold — because a lead can look perfect on paper (right title, right company size) and still have no real budget or timeline once a human actually asks.
A common mistake
Treating SQL status as purely a scoring-system output, with no human validation step, is a common mistake that lets unqualified leads flow into a rep's active pipeline and inflate forecast numbers that don't hold up.
Where it fits
SQL status is the formal entry point into a rep's active pipeline — everything before this point is marketing or SDR-owned, and everything after is the rep's responsibility to move toward a closed deal.
Key takeaways
- An SQL is a sales-accepted, sales-ready opportunity
- It sits one stage past the MQL
- Fit, interest, and timing define it
- A written definition keeps sales and marketing aligned

FAQ
Common questions.
What is the difference between an MQL and an SQL?
An MQL is marketing-flagged interest; an SQL is sales-accepted as a real opportunity. The SQL bar is higher.
Who decides if a lead is an SQL?
Sales does — based on a shared definition agreed with marketing, so the handoff is consistent.
