One of the most common questions we get from sales leaders is: How do we know if a lead is actually worth our time?
It’s a fair question, and one that trips up many teams. Without a clear lead qualification process, marketing fills the pipeline with noise, sales burns time chasing the wrong people, and real opportunities fall through the cracks.
In this article, we’ll break down what makes a lead “qualified” in B2B, how to define MQLs and SQLs clearly, and how better qualification leads to better results. This connects closely with different qualification stages like MQLs and SQLs, which define how leads move between marketing and sales.
What Is a Qualified Lead?
In B2B sales, a qualified lead is a person or company that:
- Fits your Ideal Customer Profile (ICP), and
- Shows meaningful signs of interest or buying intent.
It’s not just someone who downloaded a PDF or clicked a link. It’s someone your team believes could realistically become a customer, based on fit, behaviour, and timing.
Think of it as a filter. Lead qualification helps you separate curiosity from commitment, so your team spends time on people who matter.
Marketing Qualified Leads (MQLs)
An MQL is someone who’s shown early interest through marketing channels but isn’t ready for a sales conversation yet.
Common triggers for MQLs include:
- Downloading a whitepaper or ebook
- Subscribing to a webinar
- Repeated website visits
- Clicking on a campaign CTA
Marketing teams use lead scoring models to decide when a contact becomes “qualified.” But that score only matters if sales agrees.
That’s why defining MQL criteria should be a shared exercise. If marketing calls everything an MQL, you’re not qualifying, you’re flooding.
Our article on which top lead generation metrics to track covers how to measure marketing effectiveness without inflating lead counts.
Sales Qualified Leads (SQLs)
An SQL is a lead that’s been vetted by sales and is ready for direct outreach or discovery.
Common SQL indicators include:
- Matching your ICP (e.g. company size, industry)
- Showing buying signals (e.g. requested a demo, engaged with key content)
- Engaging in a two-way conversation
This is where lead quality really matters. Sales needs to be confident that leads are not just interested, but also capable of buying.
What happens next? Usually, a discovery call. If you’re refining your qualification criteria, our guide to discovery calls can help clarify how to structure that first conversation.
Other Qualification Stages You May Hear About
Some companies use extra labels between MQL and SQL. These aren’t always necessary, but can be helpful in high-volume or complex pipelines.
Here are a few you might encounter:
- SAL (Sales Accepted Lead)
A marketing lead that sales has reviewed and agreed to pursue. - PQL (Product Qualified Lead)
Someone who’s used your product (often in freemium or trial form) and shown signs of intent. - Engaged Account
Used in Account-Based Marketing (ABM) to describe when multiple people from a target company are showing activity.
You don’t need to adopt every acronym, but you do need a shared definition of what qualifies as “ready.”
How Businesses Decide If a Lead Is Worth Pursuing
The simplest qualification systems are based on:
- Fit (Do they match our ideal profile?)
- Intent (Are they showing signs of buying interest?)
You can use frameworks like:
- BANT (Budget, Authority, Need, Timeline)
- CHAMP (Challenges, Authority, Money, Prioritisation)
- MEDDIC (More advanced, often for enterprise deals)
But the key is consistency. Qualification criteria should:
- Be clearly documented in your CRM
- Be agreed upon by both sales and marketing
- Be reviewed regularly as your offer or market changes
Why Lead Qualification Improves Sales Results
Qualification isn’t just a checkbox. It directly improves:
- Sales efficiency: Reps spend time with the right people
- Conversion rates: More leads progress through the funnel
- Forecast accuracy: Your pipeline reflects real opportunities
- Team alignment: Less finger-pointing, more collaboration
It’s also a core stage in how this fits into the broader lead process, not an isolated sales task.
In the UK and Australia, we’ve seen clients cut their average sales cycle in half simply by tightening up their qualification stage. You don’t need more leads, you need better ones.
Poor qualification is one of the top reasons Why Most B2B Lead Generation Fails. If your pipeline feels chaotic or bloated, start here.

FAQ about Lead Qualification in B2B
What is the difference between MQL and SQL?
MQLs are early-stage leads showing marketing interest. SQLs are vetted leads ready for sales conversations.
Do all businesses use the same qualification process?
No, but the principles are similar. Frameworks like BANT and MEDDIC are common starting points.
Can a lead skip MQL and go straight to SQL?
Yes. For example, a direct demo request from a decision-maker might qualify immediately.
