Marketing glossary
An SQL marks the point where a lead has earned active sales attention after a real assessment. It protects sales capacity and makes pipeline reporting more honest, provided the team records evidence rather than optimism.

Sales qualification tests whether a plausible route to business exists. The precise framework can vary, but useful questions include:
Some answers may remain uncertain early on. Qualification does not require theatrical interrogation; it requires enough mutual clarity to justify the next investment of time.
A marketing consultancy receives an enquiry from a retailer asking for “help with social media”. The company fits its target market, but the first call reveals no agreed objective, no internal owner and no budget. The contact may remain a lead, but calling it sales qualified would inflate the pipeline.
Another retailer explains that falling repeat purchases have created a measurable revenue gap, the commercial director is sponsoring the project and the team will select a partner this quarter. The consultancy confirms that its capabilities and likely fee fit. That prospect can become an SQL with a documented next step.
Consistent SQL criteria help a business:
An SQL normally follows a marketing qualified lead in an inbound model, but it does not have to. A referral or outbound conversation may enter sales qualification directly.
One mistake is qualifying only on enthusiasm. A friendly prospect who likes the idea may still lack urgency, authority or resources. Another is treating budget as the sole test before the buyer understands the likely value and scope. Good qualification explores the whole decision rather than searching for one magic answer.
Teams also advance leads because an internal target demands a fuller pipeline. That moves uncertainty between columns without reducing it. Record disqualifying evidence, missing information and the next agreed action so the status remains auditable.
Finally, qualification should work both ways. The seller must decide whether it can deliver the outcome ethically and profitably; the buyer should decide whether the supplier’s approach fits. Disqualification can save both parties from an expensive mismatch.
An MQL meets marketing’s agreed fit and engagement threshold. An SQL has undergone a sales assessment and merits an active sales process. The exact handover must be defined jointly by the two teams.
Not in every CRM. Some businesses create an opportunity only after a further milestone, such as confirmed scope or a scheduled decision. Define both stages explicitly so reports compare consistent things.
