An MQL (Marketing Qualified Lead) is a lead who knows you and understands that you have a solution to their problem. An SQL (Sales Qualified Lead) is that same lead once they have come to a meeting or an audit. The first is the job of marketing, the second is the job of sales.
Not knowing this difference is expensive. Marketing says "we gave you 100 leads," sales says "nobody bought," and both are right. They are counting different things.
In short:
- Lead — anyone who left an application.
- MQL — a lead who passed the filter and is waiting for you.
- SQL — an MQL who came to the meeting. This is where the sale is decided.
- To get leads in as MQLs right away, use a form with 8–10 questions.
What is the difference between a lead, an MQL and an SQL?
A lead is a person who saw an ad and left their details through a form or a website. Who they are, what their business is like, whether they have money — all of that is still unknown. Sometimes when you call, you hear, "I never left an application."
With an MQL, those questions are closed. In the form they wrote their business type, their position and their problem. When you call, they are ready to talk.
An SQL is the next stage: a person who talked to the operator and came to a free audit or consultation. The salesperson sits down with them face to face.
To make it clear, the chain looks like this: Traffic → Lead → MQL → SQL → POS. The full explanation is in the article B2B sales funnel.
How can you turn a lead into an MQL right away?
We usually do not leave a lead at the "plain lead" stage. On a dedicated website or lead form we put 8–10 questions: business type, position, number of employees or revenue, current solution, main problem, decision timeline.
This raises lead cost 2 to 5 times. But the person who leaves an application is already qualified. In the end, the cost of acquiring one customer (CAC) goes down.
The most interesting part: in the right niche, a filter may not make leads more expensive at all. In the Loome case, even after a 10-step filter, applications came in from $0.16 and MQLs from $0.41. We had forecast $10–15.
When does an MQL become an SQL?
The goal of the call to an MQL is not to sell but to set a meeting. The operator listens to the customer, asks about their problems and offers a free audit:
"We have solutions for these situations. If you like, we will do a free audit: we will go through the problems together and explain what kind of solution is possible."
When the person agrees to a meeting and comes, they become an SQL. From that point on, responsibility sits with the sales team.
Where do most people go wrong?
The first mistake is counting all leads the same. If your report only shows the "number of leads," you will end up multiplying cheap and useless leads.
The second mistake is naming the price to an MQL on the phone. The person hears the price, says "I'll think about it" and disappears. The right way is to name the price in the meeting, after the problem is clear, as a range.
The third mistake is not marking MQL and SQL separately in the CRM. If you cannot see at which stage leads are lost, you cannot fix it.
How should you measure MQL and SQL?
Look at four numbers every week:
- Lead cost.
- MQL cost and the share of MQLs among leads.
- The share moving from MQL to SQL.
- The share moving from SQL to a sale.
If there are many MQLs but few SQLs, the problem is in the call. If there are many SQLs but few sales, the problem is in the meeting or the offer. The numbers show you where the problem is.
Conclusion
In short, MQL and SQL are two words you need so that marketing and sales speak the same language.
- Turn leads into MQLs with a filtered form.
- The goal of the call is a meeting.
- Mark an MQL who came to the meeting as an SQL.
- Measure the conversion of every stage in your CRM.

Frequently asked questions
What is an MQL?
An MQL (Marketing Qualified Lead) is a lead qualified by marketing: they know you, they know which ad they came from, and they understand that you have a solution to their problem. They are not a buyer yet, but they are ready for a conversation.
What is an SQL?
An SQL (Sales Qualified Lead) is an MQL who came to an audit, a consultation or a meeting. The sales result depends on the quality of the conversation at exactly this stage.
How many questions should the form have to get MQLs?
For B2B, 8–10 questions. This raises lead cost, but the people who leave applications are higher quality. At Loome, MQL still came in from $0.41 after a 10-question filter.
What should you do if there are many MQLs but few sales?
First check the MQL to SQL rate. The problem is often in the call: the operator tries to sell on the phone instead of setting a meeting, or names the price too early.
