In B2B sales, precision matters, especially when it comes to the language you use. Few terms are as frequently confused as “lead” and “prospect.” They sound similar, but they play very different roles in your sales funnel.
Understanding this difference isn’t just about semantics. It shapes how you qualify potential customers, structure your pipeline, and allocate your team’s time. Here’s how to make the distinction clear and useful.
If you’re unsure about where ‘lead’ or ‘prospect’ fits into your sales funnel, our B2B Sales Glossary breaks down 100+ key sales terms in plain language.
What Is a Lead?
A lead is someone who has shown some level of interest in your business, but hasn’t yet been qualified. They might have filled out a form, signed up for a newsletter, or downloaded a resource, but you don’t know yet if they’re a good fit.
Leads sit at the top of the sales funnel. They are typically generated through marketing activities such as ads, webinars, cold outreach, or content marketing.
A lead is someone who could become a customer, but you’re not sure yet.
What Is a Prospect?
A prospect is a lead that has been qualified. That means you’ve determined they match your target customer profile and may have a need for your solution. Importantly, your sales team is actively engaging with them.
Prospects are often considered “Sales Qualified Leads” (SQLs) and are tracked in the sales pipeline. They’ve moved beyond passive interest, they’ve entered the sales conversation.
A prospect is someone you’re actively selling to.
Lead vs Prospect: Key Differences
| Aspect | Lead | Prospect |
|---|---|---|
| Qualification | Unqualified | Qualified |
| Funnel Stage | Top of Funnel (TOFU) | Middle of Funnel (MOFU) |
| Engagement | Passive or automated | Active communication |
| Owner | Marketing or SDR | Sales rep or Account Executive |
| CRM Status | Contacted or scored | Opportunity, pipeline, or deal stage |
| Example | Signed up for a webinar | Booked a discovery call |
When Does a Lead Become a Prospect?
This handoff is one of the most important transitions in any structured sales system. A lead becomes a prospect when they meet certain criteria, often based on job title, company size, industry fit, or expressed interest, and someone on your sales team begins outreach.
In many B2B sales models, this shift happens when a Marketing Qualified Lead (MQL) becomes a Sales Qualified Lead (SQL). From that point forward, the contact is actively worked as a sales opportunity.
For clean data and better performance tracking, it’s essential that your CRM reflects this distinction consistently.

Why the Distinction Matters
Treating every lead like a prospect leads to wasted time, bloated pipelines, and poor forecasting. On the flip side, qualifying leads too slowly means missed opportunities.
Understanding the difference improves:
- Lead handoff between marketing and sales
- Sales team prioritisation
- CRM hygiene and sales reporting
- Conversion metrics across funnel stages
If you’re building or refining your sales process, this distinction should be built into your workflow, especially when using tools for lead scoring, pipeline tracking, or sales automation.
Final Take
- A lead is someone you could sell to.
- A prospect is someone you are selling to.
Making this distinction clear inside your team helps you work smarter, scale faster, and close with more consistency.

FAQ About Leads vs Prospects
What’s the difference between a lead and a prospect in sales?
A lead is an unqualified contact who has shown some interest. A prospect has been qualified and is being actively pursued by the sales team.
When does a lead become a prospect?
Typically, a lead becomes a prospect once they meet specific qualification criteria and enter the sales pipeline — often marked by moving from MQL to SQL.
Why is it important to separate leads and prospects?
It improves how teams prioritize outreach, allocate resources, and measure pipeline performance. Treating every lead like a prospect causes inefficiency and poor forecasting.
