What Is a Sales Qualified Lead (SQL)?

Definition

A sales qualified lead (SQL) is a lead that Sales has reviewed and accepted as worth actively pursuing. It's the stage after an MQL: where Marketing said “worth a look,” Sales confirms “worth my time” — usually after a conversation establishes fit, need, timing and authority.

Key takeaways

  • An SQL is an MQL that Sales has vetted and formally accepted.
  • The MQL→SQL boundary is where the Sales–Marketing SLA lives.
  • A healthy MQL→SQL rate signals the two teams agree on lead quality.

Frequently asked questions

What's the difference between an MQL and an SQL?

An MQL is Marketing's judgment that a lead deserves Sales' attention; an SQL is Sales' confirmation, after review, that the lead is genuinely worth pursuing.

Who decides if a lead becomes an SQL?

Sales does — typically a rep or SDR who reviews the MQL and confirms fit, need and timing before accepting it.

Where does a Sales Accepted Lead (SAL) fit?

A SAL is an optional stage between MQL and SQL: Sales formally accepts the lead to work it, then qualifies it into an SQL. Many teams skip the SAL step.
